LSD: Least significant difference at 5% probability level: % Change: Percent change in grain yield with reference to the grain yield of the standard sowing date under rainfed. SS, ES and LS stand for standard sowing date, early sowing date and late sowing dates, respectively. RF and SI stands for rainfed and supplemental irrigation, respectively
