Qualitative detection of undesirable constituents, adulterants in Feeds: The nutritive value of feed ingredients from the same origin may exhibit variation. The factors which are responsible for the variation are natural variation are natural variation, processing, adulteration and damage, deterioration. These days, due to shortage and high prices of feed ingredients, adulteration is one of the main problems. Feed quality can be examined by different techniques:
(a) Feed microscopy: Stereo or compound microscopy may be used for: (i) Screening method; (ii) Floatation technique.
(b) Chemical tests: For heavy metals, nitrates, phosphates, sulfates, free sulfur, salts: carbonate, chloride, salt, sugar, urea, blood, hoof or horn, leather meal, uric acid.

Common name    :    English- Fever nut/Grey Nicker
        Hindi- Kat-karanj 
        Odia- Gila

Family    :    Caesalpiniaceae

Habit & Distribution
The plant is a herb (Fig. 24 a), commonly found in hedges, thickets, scrub forests etc. and is distributed throughout India.

General Characters
It is a large climber with staright or recurved prickles. The branchlets are hairy and leaflets are 8 pairs with elliptic and lanceolate shape. Flowers are yellow, simple and usually supra-axillary. The pods are broadly oblong with 5-7.5×4 cm in size. It is 1-2 seeded and the seeds are large and round, 1-8cm diameter. The testa is very hard. The flowering time for the plant is August to October and it bears fruits during December to April.

Veneer grafting

It has one striking advantage in using the detached scion sticks for propagation, i.e. the shoot of the mother plant which is to be multiplied can be cut away from the mother plant and taken to the seedling growing in the nursery for grafting. Proper selection of scion is very important for the success of this method. The scion stick ought to be 3 to 4 months old and with some activated bud, either auxiliary or terminal. This is secured by defoliating the scion shoot about a week before the actual operation

This method can be practiced on seedling stocks grown in pots or nursery beds. A slanting cut about 5cm long on one side of scion stock, is given and the bark along with wood is removed, giving an oblique cut. Now a slanting cut on one side of the scion is made, which will just fit with the notch of the stock. The scion is then placed in position in such a way that the cambium rings of both stock and scion come in close contact. It is then wrapped tightly with 1.5cm wide tape of 200-300 gauge alkathene film keeping the terminal ends free. When the scion begins to grow at the top, (after about 3 weeks) the upper part of the stock is removed, thus forcing the buds to grow more rapidly. The plastic wrap is removed after 2-3 months.

The success is more or less the same in the entire scion (2.5 to 10.50 cm in length) but the growth of scion is always more when bigger scions are used.

Family : Rhamnaceae

Flowering: July-September

Fruiting: October-January

Botanical Description: Jackal Jujube is a very thorny straggling shrub with rusty-velvety young branches with paired thorns. Thorns are, one straight and the other recurved. Alternately arranged simple leaves are ovate to ovatelancelike, often oblique, with three prominent nerves and numerous transverse nervules. Tiny green flowers are borne in nearly stalkless velvety cymes in leaf axils. Fruits are spherical or obovoid drupes, black, shining, seeds woody.

Phytochemicals from various parts of a plant or tree such as the leaves, the flowers, the seeds, the barks, the roots and the shrubs can be isolated. Once one comes in from collecting plants in the field, it is good idea to freeze them immediately in a freezer at – 20°C or a commercial freezer held at – 80°C (Kaufman et al., 1999). According to Harborne (1984, 1998), fresh plant tissues should be used for phytochemical analysis and the material should be plunged into boiling alcohol within minutes of its collection. Alternatively, plants may be dried before extraction.

The fi rst symptom of disease appears in early spring soon after leaves come out of buds. Affected leaves become distorted and fold over as tips directed backwards. The whole lamina puckered except tip and blistered. In some leaves, part of leaf show distortion. Blistered portions are thicker, softer than the normal leaf blade. The affected areas remain green for a while and gradually become yellow and fi nally turn reddish-purple in colour. 

Introduction

Rhizobia are Gram-negative soil bacteria , aerobic nitrogen fixers and adhere to the roots of leguminous plants. Fixed nitrogen is assimilated to proteins and is transported along the plants. A part of proteins is also released in rhizosphere region.

Familiarization with various fertilizers, manure and Agri – implements: Manure: * Nutrients are added to soil for healthy growth of plants. * Continuous growing of crops makes the soil poor in nutrients. * Manures are organic substances obtained from decomposition of plants animal wastes. * Manuring is done to replenish soil with nutrients.
Advantages of manuring: * Improves water retaining capacity of the soil. * Makes the soil porous and exchange of gases becomes easy. * Increases the number of friendly microbes. * Improves the texture of the soil. * Replenishes the soil with necessary nutrients.
Fertilizers: * These are chemical substances rich in nutrients. * These are produced in factories.
Advantages of fertilizers: * Help farmers to get better yield of crops.
Disadvantages of fertilizers: * Sources of water pollution. * Make the soil less fertile. * Artificial fertilizers often cause diseases.

Family    :    Caesalpiniaceae

Habit & Distribution 
The plant is a shrub (Fig. 25a), commonly found in gardens and sometimes in wild. It is cultivated throughout India and probably native to tropical America, now widely cultivated in the tropics.

General Characters
The plant is a branched shrub or small tree that reaches up to 3-4 m in height. The leaves of the plants are bipinnate, 20-40 cm long, bearing 3-10 pairs of pinnae, each with 6-10 pairs of leaflets. The flowers are yellow or red in colour and borne in racemes up to 20 cm long. Petals are four in number, subequal and transversely oblong above the long claw. The plant flowers and fruits during most parts of the year.

It is known by different names such as Ramularia leaf spot, rust, bird’s eye spot, grey spots, and white spot. It mostly attacks leaves but can also attack fruit stalks and also fruits.

Cystic ovarian disease (Cystic ovarian degenertaion or ovarian cysts) is a common ovarian dysfunction in cattle and causes huge economic loss to farmers due to its high incidence and negative impact on the reproductive performance of cow. Animals having cysts on ovary result in anoestrum as the most significant clinical sign. Althouugh the exact cause that leads to cystic ovarian disease is not yet fully clear but altered release of LH hormone is the most accepted hypothesis.

Estimation of silage quality parameters: Process of making silage is called ensiling. The green fodder harvested at a proper stage is stored, packed and compressed in silo and it is then tightly covered to prevent the contact with air. Thus, the forage is preserved by controlled microbial anaerobic fermentation in a silo with minimum loss of nutrients for use as a succulent fodder during scarcity (lean) period. This form of preserved fodder is known as silage. Silage is prepared by obtaining enough acid content in ensiled feed which inhibit the microbial fermentation thereby preserving the green fodder. Following are
points to ponder:
1. Maize, sorghum, bajra crops having thick solid stems and rich in soluble carbohydrates, are best for silage preparation. Silage can also be prepared from oats, berseem etcetera, after wilting to 35 – 40 % dry matter.
2. Dry matter content in fodder crop for ensiling should be between 30 – 40 % (average 35 %) and should have sufficient soluble sugars for acid production during fermentation.
3. The crop is harvested in bloom stage, which is best for silage preparation.
4. If the crop is deficient in soluble carbohydrates, (for example, legumes), then a sugar industry by – product is added.
5. Silage having acidic flavour and pH 3.5 to 4.2 is considered to be excellent.
6. The crop should be properly trampled / pressed to remove the air out of silo.
7. The crop is chopped into small pieces for better microbial action due to increased surface are and sufficient acid production.

The phases of green revolution and post green revolution of Indian agriculture have assured us of security. We are now producing 354 million tons of food grains and our target is to produce 550 million tons before 2050. This is really an incredible progress for any country dominating with rural and agrarian economy. As on date, the contribution of Indian agriculture to national GDP is 14.7 % but it has to support around 60% of population. While food security has been ensured for 1480 million of population, the issues of malnutrition are standing paramount. It sounds melancholic that India is also sustaining world’s highest count of hungry population close to 51% newborn babies are underweight, 60% of rural women are anaemic, millions are deprived of dedicated safe drinking water. According to FAO, between 702 and 828 million people in the world faced hunger in 2021. Health, hygiene and nutrition are organically linked to each other, in terms of calorie intake of rural women. We are still far below of international standard. Alongside, the hemoglobin level runs below the expected level to indicate that women are runningin a moderate to acute anaemic condition. Around 840 million people are malnourished from insufficient calories. According to Black et al., (2008) nutrition related factors were found to be jointly responsible for around 35% of the child fatalities and 11% of the overall global illness burden in an analysis that took into account co-exposure. Due to poor quality of drinking water, whatever available, the propagation of water born diseases has been endemic and robust. The geo-spatial distribution of hunger and malnutrition indicates that there is location to location variation, gender discrimination, and seasonal variability across the terrain of social-cultural distribution. To make India stronger and swashbuckling we need to refocus on women health, child care and removal of economic discrimination. With acute hunger, mapping, problem of chronic hunger as well, chronic hunger hasbeen reflected through seasonal sickness, broken health and psycho-somatic downfall. Sometimes, poverty has not been the only factor for malnutrition. The other factors for malnutrition can be our wrong belief system, superstition, wrong food habit, and unscientific cooking process. With this background the objectives of the studyhave been spelt out.

The following special terms are used in grape cultivation:

1. Training: Consists chiefly in giving a shape to the vine to the various forms of support.
2. Pruning: Consists in removing canes, shoots, leaves diseased, unproductive and other vegetative parts of the vine.
3. Thinning: Thinning is the removal of flower cluster, immature fruit cluster or parts of cluster.
4. Shoots: Shoots are the current season’s top vegetative (succulent) growth arising from a bud after pruning.
5. Canes: Canes are the woody matured shoots.

The symptom appears as numerous, circular, light yellow to dark yellow spots on both the surfaces of leaves but is more prominent on the upper surface. The spot may coalesce to form large, irregular patches and soon entire leaf turns yellow and dries. Affected leaves appear as reddish-brown in colour. Excessive spotting destroys green tissues and becomes weak and yield reduced drastically
