  1. SH, super high-yielding cultivation pattern; ONM, optimized nutrient management cultivation pattern; FP, local farmer's practice cultivation pattern. Different small letters indicate significantly differences at P < 0.05 as determined by the LSD test. NS, no significant; *, ** and ***, F-values significant at 0.05, 0.01 and 0.001 levels.
