A field experiment was conducted on improving nitrogen use efficiency through split application of nitrogen in rainfed kharif sorghum (Sorghum bicolar (L.) Moench) at AICRP on Sorghum, Main Agricultural Research Station, Dharwad-Karnataka-India during kharif 2014. The experiment was laid out in split plot design with fourteen treatment combinations and three replications. The treatment consisted of two genotypes as main plots and seven methods of split application of nitrogen as sub plot. Among the genotypes DSV-6 recorded significantly higher plant height (225.2 cm), leaf area index (3.14),…mehr

A field experiment was conducted on improving nitrogen use efficiency through split application of nitrogen in rainfed kharif sorghum (Sorghum bicolar (L.) Moench) at AICRP on Sorghum, Main Agricultural Research Station, Dharwad-Karnataka-India during kharif 2014. The experiment was laid out in split plot design with fourteen treatment combinations and three replications. The treatment consisted of two genotypes as main plots and seven methods of split application of nitrogen as sub plot. Among the genotypes DSV-6 recorded significantly higher plant height (225.2 cm), leaf area index (3.14), leaf area duration (114.77 days), total dry matter production (237.28 g plant-1), grain weight ear-1(100.59 g), number of grains ear-1(4376), nitrogen use efficiency (59.36 kg kg-1), grain yield (5937 kg ha-1), fodder yield (9.09 t ha-1), net returns ( 33241 ha-1) and B:C ratio (1.86). Split application of nitrogen @ 50 % N at sowing + 25 % N at 30 DAS + 25 % N at boot leaf stage recorded significantly higher plant height (196.4 cm), leaf area index (3.51), leaf area duration (95.50 days), total dry matter production (220.48 g plant-1), grain weight ear-1(99.56 g).
