Problems of Rainfed Agriculture in India
摘要
The low productivity of agriculture in dry farming regions is due to the cumulative effect of many constraints on crop production. The constraints can be broadly grouped into (a) climatic constraints like rainfall, potential evapotranspiration, temperature, sunshine, wind velocity, and relative humidity; (b) edaphic constraints like physical, chemical, and biological; (c) technological constraints; and (d) socio-economic constraints. There are different types of production constraints according to different crops.
