Controlled-release fertilizer substitution boosts maize yield and water-nitrogen use efficiency via optimizing source-sink characteristics in saline-alkali soil

Description

This dataset contains the two-year field experimental raw data of spring maize under different controlled-release fertilizer substitution ratios in moderately saline-alkali soil of Ningxia Yellow River Irrigation Zone. Six nitrogen fertilization treatments were set: CK (no nitrogen), T0 (100% conventional urea), T25, T50, T75, T100 (25%,50%,75%,100% CRF substitution of urea nitrogen). Measured indicators include leaf photosynthetic parameters, nitrogen-metabolizing enzyme activities, dry matter translocation, grain filling characteristics, grain yield, water and nitrogen use efficiency. This dataset supports the manuscript submitted to Journal of Agriculture and Food Research.
