Note: The treatment coding details already showed in the above table. DM—day to maturity, PN—panicle number, PL—panicle length, SSP, spikelet per panicle, FGP—filled grain percent, TGW—thousand-grain weight, GY—grain yield. The mean comparison in columns was made using Tukey tests for treatments mean in both seasons and the lettering was done on basis of Tukey HSD test at 5% using simple effect. ns = non-significant
*, ** = significant at 5% and ** at 1%, respectively.
