Introduction

Flowers provide opportunity to convert them into exquisite value added products directly from fresh flowers like garland, bouquet , flower arrangements or after drying the flowers making different dried flowers products like pot pourri, wreath, painted gourds or after processing like rose water, gulkand,gulroban,perfume, essential oil, insects repellants, cosmetics etc. Beside this a number of pigments like xanthophylls, carotenoids, luteins, anthocyanins etc. which have neutraceutical properties and pharmaceuticals compounds are also prepared from flowers. The value addition results in more acceptable quality products for the domestic and export market and hence ensure high premium to the producers.

Introduction

Main stay of Indian floriculture is to grow traditional loose flowers mostly for worship, personal adornment and traditional decorations. With the evolving culture of ‘saying it with flowers’ the cut flowers sector made significant inroads in recent times. Today the traditional flowers are grown in area of 2.48 lakh hectare producing 16.58 lakh tonnes of loose flower and 4.84 lakh cut flowers (NHB 2015). India also has significant proportion of trade in potted flowering plants, ornamentals foliage plants for landscaping, turf grasses, cut foliage, dry flowers, specialty flowers, annual flower seeds and fillers. India exported floricultural produce worth Rs. 450 core (APEDA 2016) that comprises fresh cut flowers (to Europe, Japan, Australia, and Middle East, USA), loose flowers (for expatriate Indians in the Gulf and Europe), cut foliage (to Europe), dry flowers (to USA, Europe, Japan, Russia, and Australia) and potted plants (Middle East) besides seeds and planting material. The major market for domestic flowers is in Delhi, Mumbai, Calcutta, Chennai, Pune, Bangalore, Hyderabad etc. With limited infrastructure the amount of trade that takes place in the major markets varies from season to season.

Introduction

According to the definition provided by Merriam-Webster, the potato (Solanum tuberosum) is a starchy, tuberous herbaceous annual that only lasts for one growing season and is a member of the Solanaceae family. The potato, also known as the king of vegetables, is grown for its edible tubers and is the fourth largest food crop in the world after maize, wheat, and rice. It is a staple food in many parts of the world and accounts for about 2% of the world’s dietary energy supply (“Potato Pro,” 2020). It was thought that the domestication of the potato began in southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC, which is roughly 7,500–10,000 years ago (Spooner et al. 2005). Potatoes range in size, shape, color, starch content and flavor.

What is Artificial Intelligence

‘Artificial’ is taken to mean a property of a human-made machine. ‘Intelligence’ will be that when something is able to perform a new action or change its state to achieve the optimal response it could perform given external inputs. This term is coined by- John McCarthy (American computer and cognitive scientist) during 1956 So, AI is basically a machine able to mimic human intelligence by having the ability to predict, classify, learn, plan, reason and perceive.

AI is an emerging technology in the field of agriculture. AI-based equipment and machines, has taken today’s agriculture system to a different level. This technology has enhanced crop production and improved real-time monitoring, harvesting, processing and marketing . The latest technologies of automated systems using agricultural robots and drones have made a tremendous contribution in the agro-based sector. Various hi-tech computer-based systems are designed to determine various important parameters like weed detection, yield detection and crop quality and many other techniques.

The dairy sector plays a key role in ending poverty, especially for rural communities. Nearly one billion people earn their livelihood from dairy. Dairy has an important role to end hunger, achieve food security and improve the nutritional value of diets in a sustainable manner. Dairy products contribute to good health and wellbeing at all stages of life. Its nutrient-rich pack ensures a nourished and healthy population. Dairy has been linked to protection against non- communicable diseases. The Indian context for Dairying is an economic symbiosis of crop and cattle population. Livestock plays a pivotal role in the economy; animal husbandry is the most important economic activity in rural areas. The dairy sector today provides eighty million farm households with the triple benefits of nutritive food, supplementary income and productive employment for family labour, mainly for women. 

Extended Summary

Kiwifruit is recent crop introduction tohorticulture practices in Mid-Himalayan statesin India such as, Himachal Pradesh and J&K in the North-West and Sikkim, Arunachal Pradesh and Nagaland in the North-Eastern Himalayas.Over past few years this fruit has attainedimmense popularity and among consumers due to its nutritional value, while also it has gained appeal among small and marginal farmers owing to its high benefit-cost ratio,particularly through Hi-Tech cultivation techniques.

Kiwifruit,also known as Chinese gooseberry (Actinidia chinensis Patch) is believed to have originated in China,although it gained popularity in New Zealand. In India, Kiwi was first introduced in Lal Bagh at Bengaluru,however,it was soon observed that the fruit could be cultivated well only inthe semi-temperate climate of Himachal Pradesh, around1963.

India is an agriculture based country where more than half of the population depends upon agriculture. Agriculture is a primary source of livelihood for about 58% of the population of the country. Indian agriculture sector contributes about 17% of Indian’s gross domestic product (GDP) and provide employment to 50% of the country workforce (DES, 2019). The diverse ecohabitat of the Himalayan region of the country hosts a wide range of plant diversity as well as crop diversity on which native people rely for their food and nutritional security. The hilly regions of the country are potential source of agriculture production having diversified weather conditions comprises of temperate and subtropical climatic conditions and covers about 35% of total geographical area of the country. As far as agriculture is concern, agriculture marketing has been an important aspect of rural population as it provides essential links between farm producers and consumers.

• Grafts onto older seedlings result in poor root system.
• There should be no rain; otherwise, water gets inside the union and causes rotting of tissues.
• The name Mangifera was given for the first time by “Bontus” in 1658 when he referred to this as arbor Mangifera (the tree producing mango). Linnaeus also referred it as Mangifera arbor in 1747 before changing the name to its present form “Mangifera indica” in 1753.

Mango was firstly grown within glasshouse in 1960 at England.

Breeding objectives genetic resources and techniques for breeding

• There are countries that consume 100 to 150 kg yearly per capita while others which do not even make it to 10kg.
• Genetic variability is the raw material of the plant breeder.
• International network for the improvement of Banana and Plantain (1 NIBAP), Prance to conserve the available germplasm.
• Only pathogen gene-free planting material can be used for construction or distribution from the gene bank for further multiplication or utilization in any breeding program.
• Fruit breeders have therefore tended to utilize single gene variants in performance to polygenic variation.
• In general, for most commercial requirements, homozygous is inadequate by six or seven generations of selling (56 or 37).
• In the dominance hypothesis, it is assumed that the deleterious gene is normally recessive.
• The simplest approach for the selection of our breeders is mass selection.

Introduction, importance and scope of Canopy management
