2.1 Introduction

Women and Girls are born in to social and cultural system steeped in inequality and discrimination. They receive an unfair shape of opportunities, attentions and resources from the moment of their conception. One of the most inequality is Violence against Women and Girls [VAWG]. Violence against Women is a serious obstacle to development, peace and equality. It dehumanizes women and nullifies human rights and fundamental freedom. Present Article explains types of domestic violence and Government support system against Gender based Violence.

Violence againstWomen [VAW]is globally pervasive.It existsin every country, cutting across boundaries of culture, class, caste, education, income, ethnicity and age. These trends are also reflected in the status of women in India. Census data shows that while the sex ratio has risen since the last decade, it is still low at 933, the juvenile sex ratio in India hasreached an all time low of 927. Census data 2001, official statistics from the National Crimes Record Bureau [NCRB] reveals a trend of rising crimes Record Bureau [NCRB] reveals a trend of rising crimes against women. Cultural practices in India such as dowry, child marriage, sati, the Devadasi tradition and ill treatment of widows enhance girls and women’s vulnerability to the experience of violence. Gender differential treatment related to nutrition, health care, education, mobility and other life opportunities places girls and women at a higher risk of gender violation.

3.1 Introduction

Government of India has made significant impact in empowering girl child through initiation of various schemes viz; Beti Bachao Beti Padhao, Sukanya Samriddhi Yojana etc. After initiation of such types of programme for girls, Child Sex Ratio was increased during 2021-22 i.e; 929 females per 1,000 males. Recently Government of India has initiated new innovation in Beti Bachao Beti Padhao programme. Present Paper aim is to discuss the new innovations during 2017 to 2022 under this scheme.

In India under the leadership of Prime Minister Shri Narendra Modi foresee rural India as ability laden with great prospective to speed of Sustainable Development Goal. Looking at splurge of schemes targeting girl child like Beti Bachao Beti Padhao, Sukanya Samriddhi Yojana, Ladli Yojana and several other schemes empowerment of girl child seems to be heart of a plan to attain dream of Aatma Nirbhar Bharat.

Date:

Objective: To get acquainted with classmates.

Description: This is the first lab activity and has been designed to make the students feel comfortable in their new surroundings. The aim is also to help them get acquainted with their classmates as they are still new to each other. This short fun activity will help them mingle and set the tone for upcoming activities.

Date:

Objective: To understand communication process and its elements.

Description: Communication is the process by which a person shares knowledge, feelings, ideas, and information, etc. with another person(s) in such a way that each gains a common understanding about the meaning and intent of the message. Major functions of communication include sharing information, issuing instructions, persuasion and motivation. There are several elements in communication process. Anyone who takes the initiative and starts the communication process is called the source or communicator. The intended recipient of the communication content is called as the receiver. Any sign or symbol which has the same meaning for the source and the receiver is called is the message. Receiver is the intended recipient of the message and what the communicator hopes to accomplish is the objective of communication process.

Date:

Objective: To understand the significance of non-verbal communication.

Description: Non verbal communication refers to communication without the use of words. It can encompass a wide range of communication behaviour from body language to choice and use of architectural objects. It is used for repeating, substituting, complementing, regulating verbal messages and deceiving. Some of the common non verbal means of communication include: Gestures: Gestures are movement of body parts and kinesics refers to the study of body movement.

Date:

Objective: To understand the importance of paralanguage in verbal communication.

Description: Paralanguage is the variation in voice and includes vocal characteristics such as pitch, range, resonance, tempo, etc. Though it is an integral part of verbal communication, it is quite distinct from the actual signs and symbols that are used by the communicator.

Date:

Objective: To practice giving appropriate feedback.

Description: Communication is a cyclic process. The message originates from the source and is reaches the receiver. The receiver then decodes the message (i.e; makes sense)and sends a message back to the sender to convey his/her understanding or agreement with the message that has been received. Feedback not only completes the communication cycle, but also takes the process forward.

Date:

Objective:To understand the concept of perception and its role in communication.

Description: Human body receives stimuli through various sensory organs and the brain processes these stimuli and assigns meanings leading to a reaction. This process of organizing, identifying and interpreting of sensory stimuli leading to an understanding of the environment is called perception.

Date:

Objective: To understand gap in communication process.

Description: Communication is never 100 percent efficient. In other words, even an ideal situation does not lead to complete and full understanding between the sender and receiver. Often, the receiver may understand the message differently or receive only a part of the message. This happens as every individual has a different frame of reference. Frame of reference is the set of experiences, beliefs and values which influence a person’s behaviour and acts as a benchmark against which all new stimuli are interpreted. Based on the frame of reference, every individual develops a perception. Perception is the process of receiving and interpreting stimuli.

Date:

Objective: To understand the characteristics and limitations of language.

Description: Language is the structured system of symbols, which are called as words. Semantics refers to the study of the relationship between symbols and their meaning. All languages are arbitrary as the word symbol is not the thing it represents (i.e. if all of us agree, we can refer to a “cat” as “donkey”, without turning it into one!). Words can be both abstract (things that cannot be sensed directly) and concrete (things that can be experienced through sensory organs).

Date:

Objective: To prepare a non-projected audio-visual aid (chart).

Description: Audio visual aids are media that can make communication more effective through use of sound and visuals. They are of two types – projected and non-projected aids. Non projected aids are visual materials that are used as it is by the instructor and do not need any device or equipment. Examples include charts, posters, leaflets, flash cards, etc. They are easy to prepare, carry and use. They can be prepared as and when needed and multiplied at low cost.

Date:

Objective: To prepare a non-projected audio-visual aid (folder).

Date:

Objective: To prepare a non-projected audio visual aid (poster).

Description: Poster is a placard displayed in a public place to raise awareness. A well-made poster must attract attention of passers-by and motivate them to take action. Here are a few tips for making effective posters:

a) A good poster should rely on pictures rather than words. While there is no strict rule regarding the number of words, try to use no more than 10- 12 words.

b) The font size should be big enough to read from a distance as posters are displayed at public places. If there is a variation in font size, increase the size as you move from top to bottom. In addition, while choosing colours, keep the background against which the poster will be displayed in mind.

Date:

Objective: To prepare a projected audio-visual aid (power point presentation).

Description: Audio-visual aids that are magnified and projected on to a screen are called as projected audio-visual aids. There are three methods of projection:

a) Direct projection: In this case, light rays from the source of illumination pass through condenser lens, then hit the object and go through objective lens and fall on the screen. Slide projector is an example of direct projection.

Date:

Objective: To practice group discussion and understand the do’s and don’ts of group discussion process.

Overview: Group discussion is a form of discourse, which occurs when more than two people recognize a common problem, exchange and evaluate information and ideas. Their efforts may be directed towards a better understanding of the topic or solving a problem. Group discussion occurs in a face-to-face or co-acting situation. It is a democratic method in which equal opportunity is given to every participant to express his/ her opinion. In formal settings, group discussion takes place under the direction of leader. Group discussion is often used by academic institutions or employers to assess certain traits and skills of the participants. The number of participants usually is around eight, but there is no hard and fast rule. When being used as a method of assessment/ evaluation, the group is given a topic.

Date:

Objective: To practice case-based group discussion.

Overview: A case is a detailed description of anything that has happened in real life. In a case, real names are often changed to ensure confidentiality and protect the privacy, but it is not a fictitious account. A case presents a situation, or a problem and the learner is expected to suggest a solution based on the information given in the case. Case based group discussion is often used to test the analytical and reasoning ability of the participants. While participating in a case-based group discussion, the students should start by recognising and defining the problem. This is followed by listing as many solutions as possible with contributions from all the group members. In the next step, each solution is evaluated critically by the group members keeping in mind the information/ data/ facts given in the case. Finally, the best possible solution is put forth by the group. It is important to remember that there are no right or wrong solution as any option is often a trade-off.

Date:

Objective: To practice group task.

Overview: Teamwork and good interpersonal relationships are of great importance in professional life. Hence, organizations often use various methods to test qualities such as communication/influencing/leadership skills. One commonly used method is assigning group task to the candidates. Group task requires striking a balance between team goals and individual success. The team members are expected to contribute to the overall goals while furthering their individual objectives. Additionally, the evaluator can observe leadership skills, team spirit, communication skills, analytical and decision-making skills of the group members without being intrusive. One can also judge the role for which a particular member is best suited. The time assigned for a task-based group discussion/ group task can range from 10 to 60 minutes depending upon the complexity of the task.

Date:

Objective: To make group presentation.

Description: Group presentation refers to presentation of subject matter by few or a group of people. Group presentations are fairly common in professional life and hence, one should have a mastery over how to prepare and make group presentations. If handled properly, group presentations have several advantages over individual presentations. They are more attention grabbing and interesting as the mere presence of more than one individual introduces variety into the process. Work can be shared among the team members and knowledge and resources can be pooled for better outcome.

Date:

Objective: To practice public speaking.

Description: Public speaking refers to communication with a large number of audience in a face-to-face situation. Public speaking differs from most other types of communication as the roles of sender and receiver are distinct and different. Also, in case of public speaking, the onus of taking the interaction forward primarily lies with the speaker. Consequently, many people find it daunting and stressful and try to avoid public speaking situations.

Date:

Objective: To practice giving an entertainment or special occasion speech.

Overview: Entertainment and/ or special occasion speeches are short, simple and often meant to be humorous and entertaining. Special occasion speeches include welcome address, award presentation/ acceptance speech, after dinner speech, farewell speech, eulogy, etc. Entertainment or special occasion speech is often an impromptu speech i.e. they are usually given without any preparation.

Overview: Video programs are often produced in a studio environment as it is convenient, easy to manage and there are very few disruptions. A typical video production facility comprises of two areas – control room and the studio floor. Director, assistant director, video and audio technicians sit in the control room. The control room has a series of monitors that display the final and camera outputs. It may also have “on air” and “preview” monitors which display images being broadcast and to check the image before recording, respectively. The control room also has a production console, which is used to select the video and audio output.

Date:

Objective: To understand shot sizes in a video production.

Overview: Shot, in video production refers to one continuous recording by the camera. It comprises of a series of frames (still images) and There are 24 frames in one second. A shot includes eeverything recorded between switching on and switching off the record button on the camera. It can contain movement of both camera and talent.

Date:

Objective: To write a script for a short video production.

Overview: A script is a written document that contains description of the setting, characters, dialogue, and stage directions for an audio-visual production. It is used to communicate information about actors, costumes, sets, and other aspects of production to those who will be involved in program production. While screenplay tells a story, a script (especially shooting script) mainly helps in production. Another difference between a screenplay and a script is that the former conveys what the audience will see on the screen, whereas the script guides the production team. A storyboard refers to pictorial representation of shots in a sequential order. It is very handy during shooting short videos like commercial or public service messages.

Date:

Objective: To write an article for a farm publication.

Description: Print media can be used at the receivers’ convenience and can be preserved for future reference. It can also be used to reach the readers at a relatively low cost and the information can be verified by the reader. Due to these advantages, print media is an important form of communication, especially for development purpose. The term “farm publication” is used to refer to any publication that is prepared by an extension agency/ development department and contains information related to improvement of farming practices. Farm publications can be of various types such as leaflet, folder, magazine, newsletter, etc. Farm publications are very useful for literate farmers and can also be used by illiterate farmers with the help of others.

Description: A newspaper is a periodic publication containing written information about current events and other information that is of interest to the readers. A newspaper organization usually consists of the following departments:

a) Editorial department: The editorial department collects, processes and finalizes all content and images that are published in the newspaper. News/ information collected by the journalist or contributed by various writers is made readable, presentable and attractive to the readers through editing and proof reading by the editorial team.

Introduction

The term “Remote Sensing” was coined in 1950s by Ms. Evelyn Pruitt, a geographer with the U.S. Office of Naval Research, and the term is now commonly used to describe as the science and art of identifying, observing, and measuring an object on the earth surface, without having any direct contact. This process involves the detection and measurement of radiation of different wavelengths reflected or emitted from distant objects or materials through which they may be identified and categorized by class/type, substance, and spatial distribution (National Aeronautics and Space Administration—NASA). Remote sensing technology has been widely applied in various applications such as water resources, agriculture, geological studies, forestry, land use, resource exploration, etc.

Elements of Remote Sensing

The remote sensing process involves an interaction between the incident radiation and the targets of interest, exemplified by the use of imaging systems in which the following seven elements are involved; however, remote sensing also involves sensing of emitted energy and using non-imaging sensors

Introduction

Watershed management has emerged as an important research area in recent years. Understanding the morphology of the catchment is one of the widely used methods for watershed management. Morphometry is the measurement and mathematical analysis of the configuration of the earth’s surface, shape, and dimension of its landforms (Agarwal 1998; Obi Reddy et al., 2002). The study of watershed is very useful in drainage basin evaluation, silt erosion control, flood frequency analysis, watershed prioritization, natural resources management, and conservation (Waikar and Nilawar, 2014). The significance of morphometric analysis is highlighted in the basins that are either un-gauged or difficult to access. The morphometry is usually analyzed through measurement of linear, aerial, relief, gradient of channel network, and contributing ground slope of the basin (Magesh et al., 2012). The hydrological behavior of a basin can be easily determined through the areal parameters (Mahala, 2020.) The evolutionary history of any basin can be best understood through the implication of different relief morphometric measures of drainage basin (Sharma and Sarma, 2013).

GIS and RS techniques are proven convenient methods for morphometric characterization of sub-watersheds and prioritization of watersheds. As the satellite images provide a synoptic view of a large area, the RS and GIS methods become very useful in the analysis of drainage basin morphometry (Rai et al., 2017). Thus, the morphometric analysis using spatial techniques has emerged to be the fast and efficient method as compared to most of the conventional methods (Rao et al., 2010) such as manual extraction of drainage network and assigning the stream order from a published Survey of India topographic map. The present study aims at using remote sensing and GIS technology to compute various parameters of morphometric characteristics of the Chaliyar River basin.

Introduction

Groundwater resources are under stress globally due to various reasons including increasing water demand, impending climate change, industrialization, land use/land cover changes, etc. Adequate sustainable development strategies have to be adopted for the management of groundwater resources. Irrespective of the developmental status of countries all over the world, groundwater serves as a crucial resource for meeting fundamental needs. However, increasing population, water demand, surface water contamination, and recent patterns of climate unpredictability have caused increasing reliance on groundwater as reported by several researchers (Adimalla and Taloor 2020; Aladejana et al. 2020; Cuthbert et al. 2019; Green 2016; Hamed et al. 2018; Jasrotia et al. 2019; Khalaj et al. 2019; Li 2016; McGill et al. 2019; Morsy et al. 2017; Taloor et al. 2020).

Even in India, water scarcity has been reported in many parts, though the country receives relatively higher rainfall. However, the rainfall pattern has changed over the last few years. The country has been experiencing significant spatiotemporal changes in rainfall patterns, leading to fewer rainy days and more extreme rainfall, which many studies have attributed to global climate change and anthropogenic influences. The rainfall variability has substantial impacts on water availability, agricultural productivity, and welfare of the 1.2 billion people in India because agriculture in India feeds about 17.2% of the global population and more than 56% of the agricultural land is rain-fed. Rapid and heavy patterns of rainfall result in the draining of most of the rainfall as surface runoff particularly on higher slopes, and reaches the surface water bodies, thereby reducing the infiltration and subsequent groundwater recharge. These variations in rainfall have ultimately affected the groundwater behavior and availability in many river basins.

Introduction

Climate change and human activities have emerged as significant factors affecting water resources in diverse regions (Kumar et al. 2022; Haddeland et al. 2014). The escalation in human water consumption for domestic and industrial purposes enhanced by the impacts of climate change has resulted in an overall decline in water availability (Liu et al. 2017; Paul et al. 2021). Rising temperatures and altered precipitation patterns directly influence water availability for ecosystems and agriculture potentially leading to greater evapotranspiration rates, intensified rainfall events, and prolonged droughts (Sharannya et al. 2021; Myers et al. 2023). Furthermore, urbanization, deforestation, and agricultural practices alter landscapes, affecting water resources in these areas.

Water shortages pose threats to ecosystem health, and socio-economic development and disrupt agricultural production (Piao et al. 2010). Thus, ensuring sustainable and efficient water usage necessitates accounting for water usage and quantifying it in a changing environment. To comprehensively assess the significance of water resources in the environment, Falkenmark (1995) introduced the concept of blue water (BW) and green water (GW) water, particularly for managing water resources in water-stressed regions. Green water refers to the portion of precipitation that infiltrates into the unsaturated soil layer and is subsequently utilized by plants through transpiration and soil evaporation. In fact, “blue water” represents surface and groundwater flow in rivers, lakes, and aquifers (Abate et al 2024; Sharannya et al. 2021). While numerous studies have investigated the spatial and temporal variation of BW and GW using the Soil and Water Assessment Tool (SWAT) (Feng et al. 2021; Li et al. 2009; Lyu et al. 2019), fewer publications have focused on assessing these variations and uncertainties at the basin scale under varying climate scenarios (Sharma et al. 2023). Hydrological models such as SWAT, serve as valuable tools for simulating past and future hydrological changes in the watersheds using projected climate data. SWAT specifically can simulate both blue and green flows at the watershed scale.

Introduction

Rainfall is one of the climatic variables that varies very highly spatially and temporally. Understanding this micro-level variation is a crucial indicator for planning future water requirements and preparing for management strategies. Numerous researchers have delved into the distribution, variability, and trends of rainfall across diverse spatial scales, ranging from global to regional and basin levels. Nair et al. (2014) analyzed the rainfall trend and seasonality index for Kerala state in India over the last 100 years. The rainfall trend was found to be decreasing significantly in almost all the regions of the state. Nischitha et al. (2013) provide insights into the spatial and temporal variability of daily monsoon rainfall in the Tunga and Bhadra River basins in Karnataka state. Paradkar et al. (2019) evaluated the pattern of weekly rainfall by using statistical parameters such as mean, standard deviation, skewness, and kurtosis for five stations in Pratapgarh district.

Geographical Information System (GIS) proved to be an effective tool in handling information and analyzing rainfall patterns, providing visual representations, and facilitating the decision-making process (Kadir et al. (2016) and Rao et al. (2017)). Anand et al. (2020) analyzed the long-term spatial and temporal trends of rainfall in the Lower Bhavani basin in Tamil Nadu, India using GIS and statistical methods. Earls et al. (2007) compared different interpolation methods such as Inverse Distance Weighting, Spline, and Kriging (ordinary and universal) to generate a 30 m representation of the rainfall data. Spatial interpolation techniques perform differently and their evaluation should not rely solely on quantitative assessment. Wu & Hung (2016) compared the performance of three spatial interpolation techniques i.e., IDW, kriging, and spline using quantitative assessment, 2D visualization, and 3D visualization. IDW and kriging performed similarly in terms of quantitative assessment, while spline performed worse. IDW and spline performed similarly in 2D visualization, while kriging showed different behavior. Kriging was observed to be an inexact interpolation in 3D visualization, while spline tended to create extreme values along the edges of the study area. Some studies discovered that the accuracy of Kriging in the study area is higher than that of IDW or Thiessen interpolations (Earls et al. 2007; Song et al. 2008; Chen et al. 2010). GIS applications have the capability to integrate spatial data and non-spatial data like rainfall and to visualize, model, and analyze how rainfall distribution varies across space and over time, providing insights into climate change, water resource management, agricultural planning, and disaster management. The present study aims to analyze annual rainfall data pertaining to Kerala state in the GIS environment.

1.1 Introduction

Since the beginning of humankind, we have thrived as a species due to our unique capabilities. These skills have developed and progressed over the centuries to the point that, in recent decades, we have been able to build machines that can imitate our intelligence, as far as we comprehend it. A novel type of world may lie ahead of us.

Artificial intelligence is the future, and the future is here." - Dave Waters

Artificial intelligence (AI) refers to the replication of human intelligence in computers, which are programmed to think and behave in a manner similar to humans. Literacy, logic, problem-solving, perception, and linguistic appreciation are all manifestations of cognitive abilities. Artificial Intelligence refers to the development of computer systems, computer-controlled robots, or software that are designed to exhibit intelligent behavior similar to that of the human mind. The term artificial intelligence is composed of the word "Artificial," which denotes something created by humans rather than existing naturally, and "Intelligence," which refers to the capacity to gain and utilize knowledge and skills.AI is achieved by the analysis of patterns in the human brain and the evaluation of cognitive processes. The culmination of these studies leads to the creation of sophisticated software and systems with advanced intelligence. The term AI was coined by McCarthy et al. 2006 while working on Dartmouth summer research project in which they proposed that machines have the capability to emulate "every facet of learning or any other characteristic of intelligence."

2.1 Introduction

Horticulture plays a pivotal role in global food production and is essential for ensuring food security and improving nutrition. However, the increasing pressure on agricultural resources, coupled with environmental challenges, necessitates the adoption of innovative technologies to enhance productivity and sustainability. Artificial Intelligence (AI) has emerged as a powerful tool in this regard, offering unprecedented capabilities in data analysis, pattern recognition, and decision-making. In horticulture, AI holds immense potential for revolutionizing crop and soil monitoring practices, enabling more efficient resource utilization and better management strategies.

2.2 Foundations of Ai in Crop and Soil Monitoring

Artificial Intelligence (AI) forms the backbone of modern crop monitoring techniques, enabling the processing of vast amounts of agricultural data and the extraction of actionable insights. This section provides an in-depth exploration of the fundamental principles of AI, machine learning, and deep learning, elucidating their applications in crop monitoring within horticulture.

2.1.1 Understanding Artificial Intelligence (AI)

Definition and Scope: AI refers to the development of computer systems capable of performing tasks that typically require human intelligence, such as learning, reasoning, and problem-solving.

Types of AI: AI can be categorized into two broad types: narrow AI, which is designed for specific tasks, and general AI, which exhibits human-like intelligence across a wide range of domains. In the context of crop monitoring, narrow AI applications are more prevalent, focusing on tasks such as image recognition, predictive modeling, and decision support.

3.1 Training

Virtual orchards are sophisticated, simulated environments used to train agricultural robots in a controlled, risk-free setting. These virtual landscapes replicate real-world orchards with high fidelity, incorporating detailed models of trees, fruits, branches, and various terrain features. By leveraging advanced technologies like 3D modelling, physics-based simulation, and machine learning, virtual orchards provide a comprehensive platform for developing and testing robotic algorithms without the logistical challenges and costs associated with field trials. In these simulations, agricultural robots can perform various tasks, such as navigating through rows of trees, detecting and localising fruits, and executing precise pruning actions (Shamshiri et al., 2018). The virtual environment allows for testing different path planning and control algorithms, enabling researchers to fine-tune these systems for optimal performance.

Additionally, virtual orchards can simulate various environmental conditions, such as changing light levels, weather patterns, and the presence of obstacles, providing a robust testing ground for robots to adapt to dynamic scenarios. One significant advantage of virtual orchards is the ability to generate large amounts of training data for machine-learning models. Robots can be exposed to many pruning scenarios, enhancing their ability to generalize and perform effectively in real-world conditions. Furthermore, the use of virtual reality (VR) and augmented reality (AR) can aid in training human operators to control and supervise these robots, improving their proficiency and reducing the learning curve (Sarker, 2021).

4.1 Introduction

Pests and plant diseases pose serious risks to global agriculture (Strange and Scott, 2005; Oerke, 2006). Plant diseases and pests are the natural disasters that can impede a plant’s normal growth throughout the plant’s whole life cycle, from seed formation to seedling growth and may result in plant death (Liu and Wang, 2021). Diseases reduce yields in a number of important crops by 21–30% globally (Savary et al., 2019), whereas insect infestations reduce crop output by 30–33% annually (Kumar et al., 2019). For the management, accurate disease diagnosis and pest identification are essential. Artificial intelligence (AI) techniques can be a crucial addition to enable the monitoring of plant diseases and pests at a coarse scale, as traditional field scouting of these pests and diseases is labor-intensive, subject to bias, and typically shows low efficiency (Mahlein, 2016).

Agriculture is undergoing a revolution because of artificial intelligence (AI), which is replacing outdated techniques with more effective ones (Talaviya et al., 2020). AI intervention in agriculture is helping farmers increase productivity and reduce adverse environmental effects (Sujawat, 2021). The application of AI techniques has created new opportunities for scientific research as well as new instruments and ways for handling and analyzing vast volumes of data. An important benefit of AI is its capacity to spot patterns in data that are not immediately obvious or available to humans. This allows for previously unattainable new insights and discoveries (Angermueller et al., 2016; Eraslan et al., 2019). AI is currently changing how we work and live, yet its influence on pathology and entomology research is still underappreciated. AI’s cost-effectiveness, precision, quickness of performance, and adaptability are its core concepts in agriculture (Eli-Chukwu, 2019). In agriculture, artificial intelligence not only helps farmers use their abilities, but it also guides them to obtain better quality and larger yields with fewer resources (Khandelwal and Chavhan, 2019). AI-based technology addresses the issues that agricultural sector faces and helps to increase efficiency in all areas. These challenges include crop harvesting, irrigation, soil content sensitivity, crop monitoring, weeding, harvesting, and establishing.

5.1 Introduction

The application of chemical pesticides is crucial in horticultural production, but it is also one of the most hazardous agricultural operations. Overapplication can lead to significant environmental concerns. Spraying is vital for reducing harvest losses and improving productivity. According to Cho et al.,(2012), 30-35% of production damages can be prevented by reducing harmful insects and diseases through spraying. Plant protection is essential for ensuring yield quantity and quality. Effective pesticide use is crucial, as excessive application can lead to pests developing immunity, destruction of beneficial insects and natural pest enemies, and increased harmful insect populations. Excessive pesticide use also disrupts pollination, preventing fruit formation. The method of pesticide application is key to targeting the correct quantity and quality, reducing environmental contamination, and increasing sustainability (Abbas et al., 2020). Site-specific application rates in precision horticulture can decrease pesticide use. Only 30-40% of pesticides typically reach their targets, with most lost to the environment, contaminating workers and causing pollution. Protecting plants with chemicals aims to prevent infections and ensure healthy growth.

Spray drift can harm non-target plants and contaminate watercourses, posing a severe and costly problem for horticultural farmers using air-assisted variable sprayers (Seol et al., 2022). Spray drift refers to airborne spray droplets moving beyond the intended application area from aerial or ground-based methods. Studies have found that a significant portion of pesticides is lost to the air and ground, with up to 30-50% of the applied pesticides being lost through various means (Abbas et al., 2020). Modern trends emphasize the importance of sensors and precision agriculture for effective pesticide use. Understanding tree canopy physical features is crucial for effective spray application. This study focuses on recognizing and geometrically classifying canopies for adequate pesticide protection. Variable rate spraying targets only the canopy, enhancing pesticide application efficiency (Rathnayake et al., 2022). Electronic methods and innovative equipment reduce operational and environmental costs. Sensors tracking canopy characteristics and spacing ensure optimal use of inputs, promoting sustainability.

6.1 Introduction

Perennial crops are crucial for maintaining food security, despite making up only 4.2–4.7% of all agricultural acreage (Kreitzman et al., 2020). The value of fruit and nut production reached a value of USD 823 billion globally in 2020, with the top five fruit crops being apples (87 Mt), oranges (78 Mt), grapes (77 Mt), mangoes (55 Mt), and apricots (41 Mt) (Statista, 2020). The tree nut business is growing quickly, although making up a smaller share of the world’s agricultural output. Global tree nut output is expected to reach 4.2 Mt in 2019–2020, with almonds, cashews, walnuts, hazelnuts, and pistachios accounting for 31%, 17%, 21%, 12%, and 14% of the nut market share, respectively (Serna, 2020).

Tree crops require a longer investment period before producing a commercial yield; sweet cherry takes three years to attain a commercial yield, while pistachio takes ten (Rezaei et al., 2019). High-density monocultures of cultivars chosen for their potential yield, fruit quality, and disease resistance are part of optimal tree crop production techniques. These monocultures are maintained under intensive, high-input farming systems (Simon et al., 2017). However, inadequate pollination can seriously impair the quantity and quality of these agricultural products, prompting for meticulous dedication to pollination research and management (Bosch et al., 2021; Forbes et al., 2019).

Effective pollination, and on the contrary, situations in which pollination is restricted or deficient, depend on both internal and external factors (Figure 7.1, Table 7.1). The period of stigma receptivity, the lifespan of the ovule, and the quality and availability of compatible, suitable pollen are all considered as intrinsic factors (Howlett et al., 2015). Agronomic methods pertaining to plant nutrition, orchard layout, pest and disease control, pollinator activity, pollen quality, and weather patterns and their effects on flowering synchrony are examples of extrinsic factors(Toledo-Hernandez et al., 2017). Hatfield and Prueger assert that pollination is one of the phenological stages that is most sensitive to temperature, and as such, it has a significant impact on productivity (Hatfield and Prueger, 2015). Climate has been shown to be a key factor in determining pollination success and production in crops including peaches, apples, and almonds.

7.1 Introduction

Artificial intelligence (AI) is the imitation of human intellect in machines designed to emulate human activities and cognitive functions. These machines are designed to accomplish tasks that normally require human intellect, such as learning, problem solving, perception, and decision-making (Zhang et al., 2022). Horticultural crops, including fruits, vegetables, nuts, and ornamental plants, are of paramount importance in global agriculture, as they contribute significantly to food security, economic prosperity, and environmental sustainability. Nevertheless, the cultivation of these crops poses numerous challenges for growers, such as fluctuating market demand, insufficient resources, unpredictable climate conditions, and the constant threat of pests and diseases (Nowak & Grant, 2018). In recent years, the agricultural sector has experienced a significant shift owing to advancements in Artificial Intelligence (AI) technologies (Liakos et al., 2018). AI has emerged as a powerful tool for the cultivation of horticultural crops, providing solutions for boosting productivity, sustainability, and efficiency (Shrivastava & Kumar, 2021). By utilizing AI, horticulturists can overcome the traditional challenges associated with crop management, resource allocation, and environmental sustainability, paving the way for a more resilient and productive agricultural sector (Garg et al., 2019). The integration of AI into horticultural crop production encompasses a diverse range of applications, including precision agriculture, crop monitoring and management, predictive analytics, automated harvesting, and genetic improvement (Golhani et al., 2018). These applications leverage machine learning algorithms, remote sensing technologies, and data analytics to analyze vast amounts of agricultural data ranging from soil composition and weather patterns to crop health and market trends (Araus& Cairns, 2014). Through intelligent data-driven insights, AI enables farmers to make informed decisions in real-time, optimize resource utilization, minimize waste, and maximize yields (Kamilaris et al., 2017). This technological convergence offers promising prospects for food production, enabling stakeholders to explore new avenues for growth, resilience, and sustainability in horticultural crop cultivation (Mohanty et al., 2016).

Seed is the primary and most critical input in any crop production programme. A quality seed alone contributes around 15-20% towards total production. The efficacy of all other inputs to increase production will be in vain if the quality of the seed is poor. Hence, use of quality seed is crucial as it appreciably increase the productivity of the crop without depending much on other inputs. This adds to the old saying in Manu Smriti good seed in good field yield abundantly .A quality seed can be defined as genetically and physically pure seeds with high germination percentage, free from seed borne pathogens and safe moisture content. This guarantees good germination, vigorous growth, and good establishment of crop in the field.

History of Seed Industry in India

Farmers dependent mostly on traditional indigenous varieties earlier and its seed requirements were met through their own farm saved seeds or through local sources. But the quality of these seed stocks was not assured, and this resulted in drastic reduction in production as well as productivity of the crops. As a result of various crop improvement programmes, improved varieties possessing high yield potential along with additional characters of biotic and abiotic resistance came into the scenario. But the availability of the seeds of these improved varieties among the farmers remained as a problem and it limited the cultivation of these varieties. This led to the development of a well-planned systemized seed production system. Government of India had framed and brought out different legislations for regulating systemized seed production. These laws are framed to make available quality seeds and planting materials to a common farmer and equip him to approach authority for justice. Seed legislations were initiated in the country by establishment of National Seed Corporation (NSC) during 1963 under Ministry of Agriculture and the seed industry was restructured through the nationals seed projects phase I (1977-78), Phase II (1978-79) and Phase III (1990-1991). These initiatives strengthened the seed industry through formulation of seed regulations, establishment of state seed corporations and seed certification agencies thereby assured the supply of quality seeds to farmers

Technically, seed is the sexually produced matured ovule consisting of an intact embryo, endosperm and or cotyledon with protective covering (seed coat). A true seed consist of an embryonic plant, a store of food which consists of cotyledons and endosperm and a protective seed coat. Seed can also be considered as any material that is used for planting or regeneration purpose. Rather than seed, propagating materials like healthy seedlings, tuber, bulbs, rhizome, roots, cuttings, setts, slips, all types of grafts and vegetatively propagating materials used for production purpose is also referred to as seed. Thus, seeds are of two types namely sexual or botanical seed and asexual seed. Both can be used for raising the crops thus forms the agricultural seeds.

Based on the moisture content present, seeds are of two types, orthodox seeds and recalcitrant seeds. Orthodox seeds are the botanical seeds which contain moisture content less than 20%. Such seeds do not germinate even if the moisture content is more than 20% unless artificially forced to germinate. Recalcitrant seeds contain moisture content more than 20% and such seeds will not germinate if moisture content is less than 20%. These seeds cannot be stored for long and for long storage, special structures or conditions are required. Mostly perennial plant species produce this type of seeds.

The horticulture sector of our country is following an increased growth in area and production by 9% and 14 % respectively for the past six years (2015-21). It is reported that the growth rate of horticultural crop production accounts for 2.7% per year. Fruits and vegetables are the major sectors contributing to total horticulture production. As per the report of second advance estimates published by Horticulture statistics division, Ministry of Agriculture and Farmers Welfare during 2020-21, our country recorded the highest horticulture production during 2020-21 with an annual production of 329. 86 million tonnes from an area of 27.23 million hectares and the vegetable sector shared around 196.26 million tonnes production from 10.80 million hectare area. India is the largest producer of okra and ginger and second largest producer of potato, onion, cauliflower, brinjal, cabbage etc. Vegetables also contribute to the export market and onion, mixed vegetables, potatoes, tomato and green chilli are the main vegetables exporting from our country. It is estimated an export of worth Rs. 4969.73 crores from vegetables during the year 2020-21.

Importance of Vegetable Seed Production

Though we are leading in many of the vegetables in area and production, our national average in productivity of the major vegetables is far less compared to the world average. The country s estimated vegetable production by the year 2050 is 375 million tonnes from 15 million hectare with an average productivity of 25 t/ha. Low productivity is mainly because the farmers are still relying on old varieties which are less yielding and susceptible to pest and disease. Unavailability of the quality seeds of newly released varieties is one of the main reasons for this production gap. A substantial increase in yield and quality of vegetable crops can be achieved by adopting suitable agronomic practices, plant protection measures and use of quality seed. Now a days, there is an increased demand for good quality seeds of open pollinated varieties as well as hybrid seeds through which an increased vegetable production can be achieved for meeting the requirement of increasing population. So far, very limited number of vegetable hybrids have been developed and released by public sectors and majority of the existing promising hybrids in vegetables are from private sectors.

It involves all the steps starting from the extraction till sowing that makes the seed a high quality product for distribution among the farmers for a profitable crop. It reduces the spoilage during storage, increase the shelf life of the seeds, guarantees good germination and field stand thereby reduces the risk of losing the crop at early stages.

Seed Extraction

The seed extraction methods vary with the stage at which the matured fruits are harvested for seed extraction. Some of the vegetable crops are harvested at well ripe stage while some others are harvested at mature dry stage. Proper extraction should be selected taking into consideration the easiness of seed extraction from the fleshy pulp, relatively more seed recovery and less damage to the quality of seeds. There are different methods of seed extraction includes manual method, fermentation method, chemical method and mechanical method.

Manual Method

The manual method of seed extraction varies depending on the harvested fruit type. There are two types of seed extraction in vegetable crops viz., dry extraction and wet extraction.

1. Dry extraction Method

Dry extraction method is following in vegetables where mature dry fruits or mature dried pods are harvested for seed extraction. The harvested dried fruits are kept in sun for 2-3 days. The dried fruits are split open and the seeds are extracted by beating with pliable bamboo stick or by beating against a hard surface. Heavy beating should be avoided to reduce mechanical injury to the seed. Excessive mechanical injury may result in lowering of seed viability. The extracted seeds are dried in the sun between 8.00-11.00 am and 2.00-5.00 pm to reduce the moisture content to a safe level. This is followed in crops like chilli, okra, sponge gourd, ridge gourd, french bean, lablab bean, cow pea, cluster bean etc.

Solanaceae is a plant family that comprising of 2300 species and 85 genera of which, nearly one half of the species belongs to the genus Solanum. The genus Solanum includes both tuber bearing and tuber nonbearing forms. Among the tuber nonbearing forms, the major fruit vegetables growing throughout the world are tomato, brinjal and chilli. They prefer warm humid tropical climate for growth and development. Hence, the agroclimatic regions where this type of climate prevails is suitable for seed production of these vegetables. In addition to this, hybrid vigour has been widely commercially exploited in these crops because of easiness in emasculation and pollination and availability of large number of hybrid seeds per fruit.

Tomato (Solanum esculentum L.)

Tomato is the most important warm season vegetable growing throughout the world. The fruit is valued as salad vegetable and for cooking purpose. It is one of the vegetables from which, a wide variety of processed products are made. The crop is grown throughout the year in one part or other part of the country and it has become one of the indispensable fruit vegetables in our diet. It is rich in vitamin A, vitamin C, niacin, and minerals like calcium, phosphorus etc and it is rich in antioxidant, lycopene which is the carotenoid responsible for the red colour of tomato. Tomato is of recent origin, and it is the native of Peru in South America from where it spread to the entire part of the world.

Cucurbits account for the largest group of tropical vegetables, consisting of cucumber, muskmelon, bitter gourd, bottle gourd, ridge gourd, sponge gourd, snake gourd, pointed gourd, bitter gourd, ivy gourd, wax or ash gourd, chow chow or chayote, pumpkin, summer squash, winter squash, watermelon etc. They all belongs to the family Cucurbitaceae. They are herbaceous in nature and are characterized by tendril-bearing vines and adaptation to warm climate of the tropics and subtropics. Among the different genera of cucurbit vegetables, three genera viz., Cucumis (cucumbers, melons), Cucurbita (pumpkins, squash), and Citrullus (watermelons), are economically important in the world while the others hold regional importance. Most of the cucurbits are grown for its immature fruits and are consumed as salads or cooked vegetable. While, muskmelon and watermelon are used fresh as dessert fruits. Pumpkin and squashes are used in confectionaries besides as cooked vegetables. Mature ash gourd fruits are used in sweet candy preparation.

Cucurbits are low in calories, minerals, or vitamins. However, bitter gourd is rich source of vitamin C, the squash, pointed gourd, and muskmelon contain good amounts of carotene, kakrol is high in protein, and pointed gourd is rich in calcium. Bitterness in some species of cucurbits was attributed by the varying degree of bitter principles, cucurbitacin. Bitter gourd is known for its hypoglycemic activity due to phytoceutical, cheratin in the fruit, which lowers blood sugar level.

Okra is a tropical vegetable cultivating for its tender fruits. It is one of the major vegetable crops in India which can be grown in summer as well as rainy season. Fruits are rich in vitamin A, vitamin C and minerals like calcium, phosphorus, iodine, iron, and potassium. Dry fruit skins and fibers are valued for manufacture of paper and card boards. The processed product, dehydrated okra plays a considerable role in export earnings. Dried seeds of okra found to have 20-24 percent protein and 13-22% edible oil hence, used for edible oil production. Mucilaginous stem is used for clarification of cane juice for preparing jaggery. Roasted ground seed are used as coffee substitute.

Cultivated okra is believed to be originated in tropical and subtropical Africa and phytogeographic studies indicated that it arose in Abyssinian region (Ethiopia). However, existence of large number of related species with wide variability and dominant characters suggested India as the secondary centre of origin. Some researchers suggested Hindustani centre of origin mainly India, Pakistan, & Burma.

Morphology and Pollination

Okra is an erect robust herbaceous annual with green or green with reddish tinged stem. Leaves are alternate, 3-7 lobbed, palmate, hirsute and serrate. Flowers are solitary, bisexual, axillary, peduncle is 2 cm long, epicalyx is up to 10 and bracteoles narrow and hairy. Calyx is fused with corolla hence falls with corolla after anthesis. Petals are 5, separate, yellow coloured with crimson spot on claw. Staminal column consists of numerous stamens (80-120) which are united to the base of the petals. Ovary is superior, stigma is small, 5-8 fid and deep red. Fruit is pyramidal and oblong beaked capsule, longitudinally furrowed, hirsute or glabrous, dehisce longitudinally when ripe. Seeds are dark green to dark brown, round and tuberculate.

Leguminous vegetables include wide range of vegetables which can grow in climatic conditions extending from warm to cool weather. They are rich in protein, essential amino acids and fibre hence, recognized as an important component in ensuring nutritional security. They are growing for its pods for vegetable purpose, seeds as pulse or for dual purpose. They are excellent green manures that fix atmospheric nitrogen into soil and cultivation of leguminous vegetable crops is recommended as an integral component in sustainable soil fertility management. Leguminous vegetables include tropical types namely cowpea, hyacinth bean, winged bean, jack bean, sword bean while, cool season legumes include French bean, garden peas, lima bean and broad bean. They are mostly self-pollinated owing to its cleistogamous flowers. Pole or bush types are available in these crops and all are seed propagated. Among the different leguminous crops, French bean, garden peas and cowpea are under commercial cultivation while other leguminous vegetables are region specific in cultivation.

Cowpea (Vigna unguiculata)

Cowpea is a warm season legume grown both as vegetable crop as well as pulse crop. Tender pods are used as vegetable and dry beans are used as pulse. Cowpea is mainly growing for its seeds as pulse than as vegetable crop. The vegetable types bear stringless pods of more than 30 cm long, fleshy pericarp and higher monosaccharide to polysaccharide ratio. Cowpea is believed to be originated and domesticated in West or Central Africa especially Nigeria where diversity was noticed abundant. The cultivated cowpea, Vigna unguiculata is divided into different cultivar groups viz., pulse type as Vigna unguiculata var. unguiculata, Vigna unguiculata var. cylindrica or var. biflora as dual purpose type for fodder and dry seeds and vegetable type as Vigna unguiculata var. sesquipedalis (yardlong bean/string bean/asparagus bean). The cultivar groups, biflora and sesquipedalis are suggested to be originated from ssp. unguiculata in India and South East Asia respectively.

Cole crops refers to vegetable crops originated from a common ancestor, colewort or wild cliff cabbage (B. oleraceae var oleraceae or Brassica sylvestris L.) and they belong to family Brassicaceae. They prefer low temperature for growth and development hence mainly grown as temperate vegetables in temperate and subtropical climatic zones. This group of vegetable includes cabbage, cauliflower, knol khol, brussels sprout, sprouting broccoli, kale, Chinese cabbage etc. They are Mediterranean vegetables since its centre of origin is considered to be Mediterranean region. Later on, it spread into different parts of the temperate and subtropical countries. In India, cultivation of cole crops was started in the hills where temperate climate prevails and in states like Uttar Pradesh, Orissa, Bihar, Assam, West Bengal, Maharashtra and Karnataka as cool season crop. But with the introduction of tropical types which are more tolerant to high temperature cultivation, cole crops are taking new pace in the cropping system of nontraditional areas. Cabbage and cauliflower became the most widely grown cole crops though cabbage, knol khol and curly kale were the first cultivated types and cauliflower came in the mid-way followed by brussels sprout and sprouting broccoli. The genetic designation of different vegetables under cole crops were described by several workers of which Linnaeus (1753) designated all the cole crops under one species, Brassica oleraceae and in 1969, Neuwhof classified them into different forms as B oleracea var capitata L. (cabbage); B oleracea var botrytis L. (cauliflower); B oleracea var gemmifera DC. (Brussels sprout); B oleracea var italica L. (sprouting broccoli); B oleracea var gongyloides L. (knol khol) and B oleracea var acephala DC. (kale).

Cole crops are usually biennial herbs with tap root system and erect stem. They are highly cross-pollinated and temperature sensitive for the production of head and curd. They are classified as early, mid and late varieties based on the temperature requirement and duration. Among this, early varieties are found to be high temperature tolerant and late varieties are low temperature tolerant. The flowering in cole crops requires a chilling temperature of 4-70C for about 6 8 weeks which transforms the juvenile phase into reproductive stage with exceptions of some early varieties of cauliflower and sprouting broccoli. Upon receiving the chilling temperature, the central stalk will develop into reproductive shoot or multiple reproductive shoots will be formed from the curd. The earlier is seen in cabbage, brussels sprout and kale whereas, the latter in cauliflower and sprouting broccoli. The seed production of cole crops belonging to temperate groups are mostly undertaken in temperate hills especially in the hills of Uttaranchal and Himachal Pradesh whereas, seeds of tropical types are produced in plains and lower hills of India.
