An experiment was conducted at the Punjab Agricultural University, Ludhiana during kharif 2014. Three nutrient levels (125:60:30, 200:65:80, 250:80:100 kg N:P2O5:K2O /ha) as main plots and two planting geometry (60x20 and 60x15 cm) as sub plots and five hybrids (DKC 9145, Rasi 3033, PMH 4, HM 9 and Bio 9637) in sub-sub plots were evaluated. Nutrient application 250:80:100 kg N:P2O5:K2O/ha (8478 kg/ha) being at par with 200:65:80 kg/ha (8213 kg/ha) resulted in significantly higher grain yield than 125:60:30 kg N:P2O5:K2O/ha (7532 kg/ha). The mean grain yield was significantly higher with plant geometry of 60x15 cm (8357 kg/ha) than of 60x20 cm (7791 kg/ha). Bio 9637 and DKC 9145 hybrids has higher plant and ear height as compared to all other hybrids. DKC 9145 hybrid recorded significantly higher grain yield (9411 kg/ha) followed by PMH 4 (8996 kg/ha), Rasi 3033 (8051 kg/ha), Bio 9637 (7868 kg/ha) and HM 9 (6046 kg/ha). [ABSTRACT FROM AUTHOR] |
