Science > Biology > Improvement in Crop variety > Collection and Conservation of Germplasm From ancient time, humans have collected germplasm from the wild variety and domesticated it. Domestication: Domestication is the process of bringing wild species under human management. The domestication of plants is one of the first and most crucial steps in developing […]
Science > Biology > Management of Crop Production > Seed Dormancy Seed dormancy is the innate inhibition of germination of a viable seed even placed in the most favourable environment for germination. seed dormancy is also called the rest of the seed. Generally, Seeds are dormant once they leave their parent. It enables the embryo to […]
Science > Biology > Management of Crop Production > Preparation of Soil When plants of the same kind are grown and cultivated at one place on a large scale, it is called a crop. For example, a crop of wheat means that all the plants grown in a field are that of wheat. Modern agriculture […]
Science > Biology > Improvement in Crop variety > Improvement in Crop Variety The plant breeding technique is the combination of desirable and suitable characteristics from many selected crops into a single hybrid crop, then to multiply it and make the hybrid plant available to farmers for cropping. Thus Crop improvement refers to the genetic […]
Science > Biology > Management of Crop Production > Classification of Crops All living organisms need food for survival, health, growth, and development. Food provides nutrients like carbohydrates, fats, protein, vitamins, and minerals. Different crops require different climatic conditions, temperature, and photoperiods for their growth and completion of their life cycle. The growth of plants […]
Science > Biology > Improvement in Crop variety > Impact of the Green Revolution When studying the impact of the Green Revolution we have to consider both of its sides: merits and demerits Merits of the Green Revolution: Increase in Agricultural Production: The aim of the Green Revolution was to make India self-sufficient in the […]
Science > Biology > Improvement in Crop variety > The Green Revolution At the time of independence, India was partitioned into two countries. The most agriculturally productive land came under Pakistan with a small population while India has to support a larger population compared to Pakistan. Similarly, at the time of its independence, India was […]
Science > Biology > Improvement in Crop variety > Increase in Food Production Crops are plants grown on the longer area for food or other use. Branch of agriculture connected with rearing and management of crop plant is called agronomy. For the successful crop production, understanding of how crops develop and grow, how various factors […]
Science > Biology > Soil Management > Prevention of Soil Erosion Different methods of prevention of soil erosion are discussed below Vegetation: The simplest and most natural way of prevention of soil erosion is through planting vegetation. Erosion of soil from baren land is more, hence the soil must be kept covered by growing grass and […]
Science > Biology > Soil Management > Soil Erosion The removal of the top fertile layer of the soil from the soil is called soil erosion. It is a naturally occurring process that affects all landforms. In agriculture, soil erosion refers to the wearing and transportation of topsoil of the field by the natural physical […]
