| dc.description.abstract | A field and laboratory experiments were conducted at National Seed Project and Department o f Seed Science and Technology, GKVK, UAS, Bangalore respectively during Kharif 2011-2012 to assess the response o f fertilizer treatments and spacing on growth, seed yield and quality o f single cross maize hybrid NAH-2049. Experimental results revealed that fertilizer application at (T9) 225:112.5:60 NPK kg h a '+ Z n S 0 4 at 10 kg ha~'+ Boron spray (1 %)+A. chroococcum+B. megaterium+ G. fasiculatum recorded significant plant height in both male and female parent (134.90 and 152.80 cm), cob weight (135.40 g), hybrid seed yield (3237.65 kg h a 1) and germination per cent (98%) superior over other fertilizer treatments. Among the planting geometry higher hybrid seed yield (2836.90 kg h a '1) was recorded in (S() 75X30 cm planting geometry compared to 60X30 cm (2765.09 kg h a '1). Growth, seed yield and quality attributes viz.,num ber o f leaves per plant (13.30), days to 50 per cent tasseling and silking (45.33 and 46.67 days), pith weight (34.27 g), 100 seed weight (35.61 g) and seedling dry weight (90.57 mg) were observed in fertilizer application at 225:112.5:60 NPK kg ha^+lO kg ZnS0 4 + Boron spray (1%) + A. hroococcum+ B. megaterinm+ G. fasiculatum with planting geometry o f 75X30cm. Significant pollen viability per cent (89.89%) was recorded in fertilizer treatment (150:75:40 N PK kg ha ')+Z nS0 4 spray(2%)+ Boron spray (1%) in the male parent (M A I-105). Interaction effect o f treatment T9S1 and non aged hybrid seeds showed significant differencefor higher shoot length (15.79 cm), root length (20.46 cm) and seedling vigour index I and II (3290 and 8996). | en_US |
