Food is the basic requirement for maintaining the life process. Plants supply the bulk of foods required for human and animal. With limited cultivable area and ever increasing pressure of human population, the demand for food is constantly rising which can not be alone met by conventional plant breeding technologies. Novel techniques like plant genetic engineering are gaining momentum for production of superior plants or yield enhancement of a species.  It has been observed that the most commercially successful application of recombinant DNA technology is in genetic engineering of plants, which led development of multinational seed companies deriving monetary benefit from genetically modified crop and food products. From production of herbicide resistant or insect pest tolerant plants to alter the inherent quality composition of human food, plant genetic engineering has established firmly the commercial viability of recombinant DNA technology.

Abstract
India’s agriculture, a foundational pillar of its economy, boasts a rich history dating back to the Indus Valley Civilization. Despite employing 40% of the workforce and achieving global leadership in commodities like spices, pulses, and milk, agriculture’s GDP contribution has declined to 15-18%. Challenges such as price volatility, climate change, trade barriers, and infrastructure deficits hinder the sector’s global competitiveness. However, opportunities abound in agri-tech innovations, organic farming, and expanding exports of high-value products like basmati rice and Alphonso mangoes. Strategic policy reform, sustainable practices, and investment in infrastructure and technology can position India as a global agricultural powerhouse.

1. MATURITY INDICES
Maturity indices (right time of harvesting) are quality factors that give clues as to when a product should be harvested to allow marketing flexibility and ensure the attainment of minimum acceptable quality to the user. It also refers to the set of criteria used to determine the stage of maturity for harvesting the horticultural crops. Commodities harvested either pre-mature or too late are more susceptible to postharvest physiological disorders, diseases and have poor shelf life than harvested at right stage of maturity. The pickers/ handlers are trained in methods of identifying produce that is ready for harvest. However, optimum harvesting stages depends upon type of produce and their final use. Horticultural crops may be harvested at two main maturity levels i.e., physiological maturity and commercial or horticultural maturity. Therefore, the proper stage/maturity indices for harvesting of all horticultural crops should be identified for their implementation during harvesting. Horticultural maturity in relation to developmental stages of the plants is depicted in Fig 3.1.
Maturity indices are different for different horticultural crops and are employed to:
1. Ensure sensory quality (flavour, colour, aroma, and texture) and nutritional quality: Harvesting horticultural produce too early (under-developed or immature produce) will result

A reservoir stores water behind a dam and can reduce downstream flooding by temporarily retaining part of the incoming flood volume. Its effectiveness depends on available storage, inflow characteristics, outlet capacity, operating rules, forecasting information, and the timing of releases. Reservoirs may also serve irrigation, municipal supply, hydropower, navigation, recreation, and environmental purposes, making their planning a multipurpose undertaking. This chapter introduces reservoir terminology, classifications, storage zones, capacity determination, site selection, sedimentation, and operating principles. It explains how flood-storage space modifies peak discharge and discusses reservoir routing, release regulation, design limitations, safety considerations, and the role of coordinated reservoir systems in basin-wide flood management.

The seven basic tools of quality control are practical graphical techniques used to identify, analyse and resolve manufacturing problems systematically. Associated with Japanese quality expert Kaoru Ishikawa, they can be applied by employees at different organizational levels. In textile and apparel production, these tools support defect tracking, process control, waste reduction and buyer compliance. They consist of the cause-and-effect or fishbone diagram, check sheet, control chart, histogram, Pareto chart, scatter diagram and flow chart. Together, they help collect and organize information, reveal patterns, identify major sources of defects, investigate relationships between variables, map processes and determine root causes, thereby supporting evidence-based corrective action and continual improvement.

Jalshakti: It is a material (starch based polymer) which can absorb and hold 80-100 times its weight of water. It is a gel on which plant roots lock themselves and tap the water. It can be used on most soils and in all composts to promote vigorous growth and minimise plant stress. It is used by mixing with growing medium at the rate of 1-2% by weight. Plant roots attach themselves to hydrated granules of the chemical and tap their water store. Jalshakti reduces watering needs.

Jam: Concentrated fruit pulp with natural fruit flavour where pectin imparts a good set and high sugar concentration (68%) facilitates its preservation.
 
Jungle: The general Indian term for forest.

X₁, X₂, X₃ : The symbols used to designate the first, second and third generation of X-ray treated plants/seeds.

Xanthophyll : A carotenoid plant pigment (carotene), yellowish in colour, present in chloroplasts and other plants parts where chlorophyll is absent, It assists in photosynthesis.

Xenia: i) The direct influence of foreign pollen on the endosperm due to phenomenon of double fertiliztion which may allow the male parent to affect the appearance of seed. ii) Changes due to effect of foreign pollen in visible characters of endosporem, e.g. Maize- when variety with white endosperm is pollinated by one with deep yellow endosperm, endosperm of resulting seed is pale yellow.

Yaw: Aircraft rotation around the vertical axis (NCRST).

Yeasts : Unicellular micro-organisms, (fungi) producing zymase (enzyme), which converts sugars into alchohol and CO₂. A single-celled ascomycete fungus, economically important in capable of fermentation and an important source of vitamins.

Yield: Plant part harvested and the quantity of it. In agriculture, necessarily related to a specified crop or crops or to a group of animals or to an area, and to a period of time. For multipurpose trees, the amount of each specified part harvested. See also Production.

Complete fracture- It is a fracture in which there is complete loss of bone continuity and the bone is divided into two or more fragments (Fig.1).

Green stick fracture- It is the fracture in which, the cortex opposite to the bending force fractures completely, while the cortex under the force remains in tact, commonly seen in immature animals, (Fig-2)

Overriding fracture-A fracture in which the fragments lie side by side, causing shortening of limb (Fig-3)

Transverse fracture-The fracture line here runs transverse to the long axis of bone. Such type of fracture is caused by bending forces (Fig-4).

Oblique fracture- In this the fracture line runs oblique to the long axis of the bone. Such type of fracture is caused by bending with axial compression (Fig-5).

Spiral fracture-Here the fracture line spirals along the long axis of bone. Such type of fracture is caused by torsion, twisting or rotational forces e.g. in humorous (Fig-6)

Comminuted fracture- In this fracture, at least three fracture lines inter connect each other at one point (Fig-7).

Definition : These are the splints made out of light metal rods or bamboo for correction and immobilization of middle and higher level fracture in animals.

Large animal orthopedic patients are often managed with modified Thomas splints and to achieve an acceptable outcome with this device the following points should be kept in mind.

Animals initially find discomfort with the splint and try to reject it by kicking and often show violent movements. Hence initial acclimatization with the device by close observation and supervision of the patient is essential.

Recumbent animals should be supported in standing position by a sling and they should be managed with the principle “12 hrs on sling and 12 hours on floor”.

Movement of the animal should be restricted.

Definition

Wound with infection with 6 hours of occurrence can be brought to non infected stage by flushing.

Procedure

The infected wound at fracture site is cleaned / flushed thoroughly using sufficient quantity with antiseptic solution.

The site is applied with topical antiseptic / antibiotic and the size of the wound is reduced by placing interrupted stitches for skin closure.

For drainage of inflammatory fluid, the counter opening is made as the distal part of the swelling of the dependent part of flushing catheter is placed inside to carry out regular flushing of the wound without removing the immobilizer.

The fracture site is immobilized as per the conventional procedure using POP cast leaving two window over the opening of counter opening site.
