Nitrogen rate and plant density interaction enhances radiation interception, yield and nitrogen use efficiency of mechanically transplanted rice

With the development of hybrid rice cultivars and mechanized planting technologies, it is hypothesized that the grain yield and nitrogen (N) use efficiency of mechanically transplanted rice could be further improved by harnessing the compensatory effects from the N rate and plant density on individual plants and populations. We evaluated the interactive effects of the N rate and plant density on the grain yield and N use efficiency of rice in...
