| dc.description.abstract | Under medium land conditions of Bihar plateau rainy seasons paddy is harvested late, thus mustard sowing gets delayed causing drastic yield reduction. Keeping in view the above fact an experiment was conducted during winter season of 1997-98 on sandy loam soil having 170, 13.24 and 148 kg/ha available NP and K respectively with pH 6.0 to study the effect of sowing method and nitrogen level on growth, development, yield, quality and economics of mustard. The treatments consisted of three sowing methods- paira, broadcast and line sowing in main plots and four nitrogen level 0,40,80 and 120 kg/ha in sub-plots. Experiment was laid out in split plot design and replicated thrice.. Results revealed that paira sown mustard produced maximum (6.04 q/ha) and straw (27.46 q/ha) yield as a result of higher dry matter (306,79 g/m² at maturity), CGR (5.57 g/m²/day between 50-70 DAS), RGR (0.113 g/g/day between 30-50 DAS), maturity (123 days), plant height (104.6 cm), secondary branches/plant (5.8), siliquae/ plant (59). Consequently heat unit requirement (1610 kg/ha), net energy output (35,000 MJ/ha). energy use efficiency (7.09), net return (Rs.5,768/ha) and benefit: cost ratio (1.40) was higher under paira than broadcast and line sown crop. Crop with 120 kg N/ha produced maximum seed (7.87 q/ha) and straw (23.17 q/ha) yield owing to higher dry matter accumulation (369.88 g/m²), CGR (5.14 g/m²/day) and RGR (0.083 g/g/day) between 50 70 DAS and maturity (119 days). Similarly primary (4.8) and secondary (6.2) branches/plant, siliquae/plant (77), oil yield (263 kg/ha), N-uptake (73.19 kg/ha), net energy output (43,646 MJ/ha), net return (Rs.7,641/ha) and benefit cost ratio (1.58) was also high with 120 kg N/ha. Mustard crop sown as paira with 120 kg N/ha proved better for higher productivity and monetary advantage . | |
