This study undertaken during rabi season of 2017 and 2018 at Agricultural Research Station, Karimnagar, Telangana to study the effect of planting row ratios of female: male for seed production of Maize hybrid Karimnagar makka-1. The flowering showed that male inbred has taken 60 days after sowing (DAS) to 50% pollen shedding as against 64 days in both 4:1 and 5:1 row ratios and female showed 50% silking at 63 DAS compared to 66 days in both 4:1 and 5:1 row ratios. The 5:1 row ratio recorded significantly more cob length (18.3 cm). Kernel number (29.5), 100-seed weight (39.3g), grain weight per cob (107.6g), seed yield of (2597 Kg/ha) and net returns (Rs. 3,93,632/ha) compared to 4:1 row ratio (17.9 cm, 27.3, 36.6 g, 99 g, 2094 Kg/ha and Rs. 3,05,132 / ha respectively) indicating 19.3 and 22.5% increased yield and net returns over 4:1 row ratio which in turn resulted significantly higher yield over 3:1 row ratio |
