Quantitative analysis of yield and soil water balance for summer maize on the piedmont of the North China

Jingjing WANG,Feng HUANG,Baoguo LI

Frontiers of Agricultural Science and Engineering 2015, Volume 2, Issue 4,   Pages 295-310 doi: 10.15302/J-FASE-2015074

Abstract: production area in China, but the current winter wheat-summer maize system has resulted in a large waterThis water-shortage necessitates the improvement of crop water productivity in the NCP.A crop water model, AquaCrop, was adopted to investigate yield and water productivity (WP) for rain-fedThe RMSE between the simulated and measured soil water storage at depth of 0–100 cm ranged from 4.09capillary groundwater would not result in groundwater over-tapping since the precipitation can meet the water
