abstract
The present investigation was carried out to study the influence of staggered sowing of male parent along with additional nitrogen dose of 10 kg/ha to male parent on synchronization of flowering. The results of the experiment revealed that male parent flowered late by 6.41days than the female parent with simultaneous sowing (V₁). Among the different techniques to achieve synchronization of flowering, sowing of male parent (CPRT-112) by six days earlier to female (V₃) along with additional nitrogen dose of 10 kg/ha at 25 DAS to male parent (N₂) resulted in better synchronization of flowering (0.53 days). This treatment also hastened the days to panicle initiation in male parent (43.53 days), days to 50% flowering in male parent (52.75 days), increased the ear head weight (34.27 g), number of seeds per ear head (1853.00), seed weight per ear head (19.46 g), seed set (88.13%), highest seed yield (2701.96 kg/ha) and 1000 seed weight (10.76 g) as compared to other treatments.
