Abstract
The effects of subsoiling strategies and rates of nitrogen application on the nitrogen uptake and use efficiency and grain yield using the maize cultivars Zhengdan958(ZD958) were studied. The experiment followed a split plot experiment design, taking the various subsoiling treatments(CK: no-subsoiling; T1: interval subsoiling; T2: each row subsoiling) in the main-plots and N supply treatments as split-plot(0, 112.5, 225, 337.5 kg/ha). The results indicated that a wide annual variability in grain yield for subsoiling strategies and nitrogen application. The yield of T1 and T2 increased by 9.62%, 8.81%, respectively, compared to no-subsoiling, and the yield of N2, N1, and N3, increased by 65.32%, 62.60% and 49.09%, respectively, compared to N0 application. The yield increased mainly due to greater the kernel numbers and grain weight. With increasing of nitrogen application, nitrogen partial factor productivity, nitrogen recovery efficiency and nitrogen agronomic efficiency(show a decline current) is shown to reduce a current. It was concluded that use of interval subsoiling and each row subsoiling mode consistently could increase maize nitrogen physiological efficiency and nitrogen partial factor compared to no-subsoiling.
