Sinopsis de RAINFED AGRICULTURE

The chapters of the book have been selected and arranged in such a manner as to lead the students through the entire gamut of rainfed agriculture supported by suitable examples and diagrams. The topics covered are most relevant in view of growing interests in rainfed agriculture technologies. The focus is on new concept and approaches &nbsp,in dryland and rainfed lands, rainfed farming-introduction, characteristics, distribution and problems, efficient management of rainfed crops, water harvesting and moisture conservation, study of mulches and antitranspirants, principles of intercropping, concept of watershed resource management, drought and its management, soil erosion-definition, nature and extent of erosion, stress physiology, scope of agro-horticultural, agro-forestry and silvi-pasture in dryland agriculture etc.Rainfed agriculture is practiced in most of the arid and semiarid areas of India.&nbsp,About 67 % of arable land in India (143.2 m ha) is rainfed. In terms of production&nbsp,rainfed agriculture accounts for production of more than 40 per cent of total&nbsp,food grains, nearly 75 per cent of oilseeds, 90 per cent of pulses and 70 per cent&nbsp,of cotton. Most of the rainfed lands are typified by highly fragile natural resource&nbsp,base, the rainfall is low, soils are often coarse textured, sandy, inherently low in fertility, organic matter and water holding capacity, and are easily susceptible&nbsp,to wind and water erosion. Deterioration of natural resources is the main issue&nbsp,threatening sustainable development of rainfed agriculture, more so in the Third&nbsp,World Countries.India will have to produce 300 million tonnes of food grains to&nbsp,feed 1.5 billion populations (approx.) in the coming years. This target cannot be&nbsp,realized from irrigated areas alone as we have irrigation potential for 178&nbsp,million &nbsp,hectares only. Therefore, we will have to evolve an appropriate technology for&nbsp,dry land farming.
