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.

Common name    :    English- Elephant ear taro
        Hindi- Kachu/Kachlu
        Odia- Saru

Family    :    Araceae

Habit & Distribution
It is a herb (Fig. 35 a), commonly found in damp, shady places and also cultivated. The plant is widely distributed throughout the hotter parts of India.

General Characters
The plant is a tuberous bulb plant growing about 3-5 ft in height. The plant has large leaves. The leaves are heart shapes, 2-3 ft long with a long stalk of about 3 ft height. The flowers are yellowish-white spathes and spadixes are frequently produced. It bears flowers and fruits during June-November. 

This crop is gaining importance as a main ingredient in Indian diet due to its medicinal properties. Large areas are under its cultivation and the larger fruited varieties have become very popular. It is one of the prime constituents in ayurvedic preparations
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.

India, with 118.7 million farmers, which accounts for more than half of its population, depends on agriculture as its primary source of income. However, the use of technology in the agricultural industry has been limited in India. As a result, the agriculture industry in India contributes merely 17-18% to its GDP. However, in the last couple of years, India has seen a rise in the number of agri-tech startups that are not only making technology more accessible but also helping these farmers to improve their lives. Today, we will take a look at top 10 agri-tech startups helping Indian farmers.

Introduction

Ammonia is the major end product in the breakdown of proteins in fish. Fish digest the protein in their feed and excrete ammonia through their gills and in their faces. The amount of ammonia excreted by fish varies with the amount of feed put into the pond or culture system – increasing as feeding rates increase. Ammonia also enters the pond from bacterial decomposition of organic matter such as uneaten feed or dead algae and aquatic plants.

Definition

Fracture of humerus bone and femur bone are generally categorised under higher level fracture.

Methods Used For Fracture Repair

These level fractures are repaired appropriately by intramedullary pinning and Thomas splint application.

Only pinning or only Thomas splint are not the method for its repair as the distal fragments of bone get tourqed by pinning only and the fracture fragments get distracted by simple Thomas splint application.

Hence after pinning a humerus or femur bone, the limbs are kept immobilised perfectly by Thomas splint application.

When pinning as well as Thomas splint application are not possible the fractured bones are kept immobilised with fevicol gum bandage only. So for this purpose modification of velpeau sling is generally adopted and animal is restrained within limited space for 21 days.

Purpose: This test is conducted to determine the boldness and soundness of the seeds. The weight of a given number of seeds of different varieties or kinds will vary. This variation is due to boldness and soundness of the seeds. The seeds will vary according to the soil fertility, variety and other environmental conditions. Higher the weight of a variety per thousand seeds, better is the variety for cultivation.

Materials and equipments: Scale, balance and seeds.

Aim

To determine the contours by cross-section method using dumpy level.
