Abstract:A mulched drip fertigation system is an effective way to improve maize yield, but at present, the efficiency of nutrient delivery and water use are generally low. Therefore, this study conducted optimization field experiments to identify the main factors limiting the delivery of water and fertilizer, including regulations on nitrogen (N) fertilizer, irrigation conditions, planting density and maize varieties, in the semi-arid area of Northeast China. As part of an effort to close the yield gap for maize, an op… Show more
