As the present study draws to a close, it opens up a myriad of possibilities for future research and exploration in the field of the present study. The insights gained and the findings presented in this thesis may provide a foundation for building upon and extending the existing body of knowledge. By identifying key areas that require additional attention and offering suggestions for future studies, this section of the chapter aims to inspire and guide researchers in their pursuit of enhancing our understanding and driving progress in this dynamic and evolving field.

The present study leaves behind the following domains which may be researched out in future:

1) The present research can be replicated with varied geo-spatial situations viz., in different locations and settings, with different respondents, with spatio-temporal expansion and methodological innovation.

2) PRA tools and materials can be deployed to collect more specific data to compensate for the inadequate information to go for the classical statistical approaches.

3) Multi-criteria decision analysis (MCDA) techniques can be integrated with mental modelling and fuzzy logic cognitive mapping so to enhance the decision-making process.

4) To realize the full potential of these frameworks, collaboration and knowledge sharing among researchers, practitioners, policymakers, and farmers are essential. Continued research and development efforts are needed to refine and validate the models, enhance user-friendliness, and adapt them to diverse agricultural systems and contexts.

Breaking of soil aggregates and dispersion followed by a rapid drying leads to rearrangement and coherence of soil solids in the form of surface crust. The cohesion exhibited by soil upon drying is directly related to surface crusting and clod formation. The formation of soil crusts and hard clods is a major structural feature of soils. Seedling emergence of cereal crops is generally controlled by point resistance around the shoot tip (Richards, 1953). Penetrometer, which measures the resistance to vertical penetration in soil, is an effective instrument to evaluate the crust strength. A relationship between penetration resistance and seedling emergence would serve as a guide to ensure optimum soil condition for a desired plant density.

Apparatus and Accessories

Penetrometer, moisture box, trowel, electronic balance and oven.

5.1 Volumetric Techniques or Titrimetric Analysis

Acid Base Neutralization Reactions-Acidimetry & Alkalimetry

Oxidation –Reduction Reactions-Oxidometry (Permanganometry) & Dichrometry

Introduction

The pH (hydrogen ion concentration) of the environment provides the maximum effect on the growth of bacteria. Each organism grows at its optimal pH. Due to variation in other factors such as temperature, osmotic pressure etc marked changes in pH have also been observed.

Requirements

1. Erlenmeyer flasks (100 ml)
2. Culture of E. coli
3. Pipettes
4. Spectrophotometer
5. pH meter

Procedure

Introduction

Subculture is key skill in bacteriological laboratory allowing us to colony propagate a pure culture in single colony. Pure cultures are essential for characterization such as identification using biochemical test or antimicrobial susceptibility testing.

Protocol

1. Label your fresh blood agar plate.

2. Select a single colony to subculture (colonies grows by clonal expansion; each colony should be a pure strain.)

3. Use the colony you have just picked to make the 1st streak on your fresh plate.

Objective
After performing this experiment you will be able to learn:
pH value of packaging material.

Introduction

As mentioned earlier, these tests are performed to assess the suitability of the board for printing, corrosion protection, food packaging etc. The presence of acid in paper or paper possessing an acidic reaction is a property of specific importance. Not only may the presence of acid effect the aging properties of paper, but it also may act upon materials that come into contact with the paper. In addition, the sizing of paper, wet strength treatment, and dye and fillers retention, usually depend upon the addition of alum or other acidic materials to the beater furnish. Hence many appers are acidic to various degrees at the time of manufacture. pH is a measure of hydrogen ion present which depends both upon the amount of acidic material and upon its degree of ionization. Hence, pH does not measure the amount of acid present. Since it is the 'activity or ‘intensity’ of acid that is usually of most interest, the pH value is the more common test.

Common name    :    English- Adlay/Job’s tear
        Hindi- Gurlu 
        Odia- Garagada

Family    :    Poaceae

Habit & Distribution
The plant is a herb (Fig. 34 a), usually found near water bodies, way sides of agricultural lands etc. It is widely distributed throughout the hot and damp parts of India and commonly seen in tropics.

General Characters
The plant is an annual grass rooting at the lower nodes, spongy, glabarous and grows up to 0.9-2 m in height. The leaves are flat, linear, and acuminate with a strong midrib and 10-40 cm long and 205-4 cm in width. The spikes are 6-10 cm long, erect and penduncled. The fruits are hard, bony, ovoid, shining white or nearly black in colour. It bears flowers during September to November and carries fruits during December to February.

Paper chromatography (P.C.) is the easiest to perform and requires simple and ordinary apparatus. It easily provides qualitative information since components of a mixture can be separated based on their mobilities or molecular weights. It also can provide quantitative information if some special attention and calculation procedures are followed. Paper chromatography is a technique that involves placing a small dot or line of sample solution on to a strip of chromatography paper. The paper is placed in a jar containing a shallow layer of solvent and sealed. As the solvent rises through the paper, it meets the sample mixture, which starts to travel up the paper with the solvent. This paper is made of cellulose, a polar substance, and the compounds within the mixture travel farther if they are non-polar. More polar substances bond with the cellulose paper more quickly, and therefore do not travel as far.

Abstract

Although women were not recognized as essential components of Agriculture for a long time, of late due recognition has been given to the role of women in agricultural production and steps have been taken to bring more and more women farmers into main stream, through Shree Shakthi Sanghas and Self Help Groups for women. Special projects aided by outside agencies and voluntary organizations such as WYTEP, IRDP, TRYSEM, DWCRA etc. provide training to farm women.These operations include selection and treatment of seed, protection of the seed or plant material, land preparation, application of manures and fertilizers, sowing or planting, nursery raising, irrigation, weeding, earthing up, pinching or thinning, training and pruning top dressing, plant protection, harvesting, transport and post-harvest operations such as threshing, winnowing, sieving, cleaning, drying, grading, packing and storage, joining hands with men etc. They also do marketing and disposal of the produce. For household use they take care in hulling, flowering, pounding etc.

Purpose- One of the important operation for horticulture crops is raising of seedlings (vegetable, fruit trees, shrubs and flowering annuals). Seedlings are either directly planted as in the case of some vegetables, flowering annuals, shrubs and trees or may used as root stock as in the case of mango, citrus etc. For healthy and good stand of seedlings proper preparation of nursery beds is essential. Since large number of seedlings are raised in a consideration. The protection of seedlings from pest, diseases, strong sun and wind is very important. These factor will vary if seedlings are raised under Low Tunnel Polyhouse.

Bark-eating caterpillars - Indarbela quadrinotata, I. tertraonis: Metarbelidae
The larvae of this species make zigzag galleries and feed on the bark under silken ribbon- shaped webs. They are stout and dirty brown in colour.
Fruit- borer : Deudorix Isocrates : Lycaenidae: The larvae of this beautiful butterfly cause considerable damage (up to 42%) to fruits.  They start feeding while the fruit is tender, and growing. During severe infestations, chemical control may be warranted. This can be done by spraying contact insecticides like malathion, or dichlorvos or  fenvalerate or other synthetic pyrethroids.

Abstract

Women become major players in creating sustainable livelihood in rural areas. Though they are the major work force compared to men in agriculture and allied areas, they are considered as invisible entity. Their contribution in total labour force itself is about 55 to 60 per cent. They play multiple roles both in and outside the home by ensuring food security and substantiating nutritional security to the family as a whole. Empowering these women with knowledge and skill to take up vocational income generating activities is prime need of the hour. Further, building their capacities on managerial skills, decision making, and technical competency is also equally important area of concern.
