Crop water requirement (ETc) of different crops of middle Gujarat

Journal of Agrometeorology, 2016
Accurate estimation of crop water requirements (ETc) of any crop is essentially required for irrigation scheduling and water management. The present study was undertaken to estimate the crop water requirement (ETc) of ten major crops (rice, wheat, maize, pearl millet, chickpea, green gram, soybean, groundnut, mustard and cotton) grown in different ...
