Low light is a common environmental factor that adversely affects rice yields. This study was conducted to evaluate the combined effect of hill density and nitrogen (N) fertilizer rate on yield attributes in hybrid rice under low-light conditions. Field experiments were conducted in 2014 and 2015. Two hybrid rice cultivars (Y-liangyou 1 and Luoyou 9348) were grown under combinations of three hill density levels (high, 40 x 10(4) hills ha(-1); moderate, 27 x 10(4) hills ha(-1); low, 14 x 10(4) hills ha(-1)) and two N rate levels (high, 240 kg ha(-1); moderate, 143-148 kg ha(-1)), and shaded fro...
