Factors Affecting Watershed Management and Impact of Watershed Management Program on Sustainable Agagement. The watershed areas of the country are suffering from the following problems: (1) different degradation problems; (2) improper land use; (3) excessive cropping; (4) shifting cultivation; (5) slope cultivation; (6) overgrazing; and (7) human and animal pressure, etc., which cause severe soil

Plant Ideotype, Their Types, and Ideotype for Dryland Farming,crop ideotype is an important prerequisite for water-saving cultivation and high-yield breeding programs in dryland crops. There are various ideotype types viz., isolation ideotype, competition ideotype, and crop ideotype. The ideotype for dryland farming has the following characteristics: drought t

Introduction, Types, and History of Rainfed Agriculture and Watershed Management in India,untries. Out of 143 m ha cultivated land about 43 m ha are under irrigation and the rest of the area (about 70%) is rainfed, but all is not too dry and is the food basket for the poor, with a millet-dominant crop pattern. Rain-dependent areas can be broadly split into two: “dryland areas,” which rec

In arid and semi-arid regions, the soils are over-salted (saline-alkali soils), while in sub-humid and humid regions, the soils are acidic (acid soils). Micronutrients and ameliorants, particularly lime, are inadequate and require periodic supple

Soil and Water Conservation Techniques in Rainfed Areas,r conservation help to improve the rate at which water is absorbed by the soil. These are used when the land slope is less than 2%. Agronomic measures include conservation tillage, deep tillage, conservation farming, contour farming, mulching, growing of cover crops, and strip cropping. However, eng
