Abstract: An experiment was conducted to study the effect of nitrogen management on growth and yield of parching sorghum genotypes (Sorghum bicolour L. Moench) during 2017-18. The results revealed that among the parching sorghum genotypes, Gulbhendi Local-1 showed significantly higher plant height, dry matter plant-1 and stem diameter as compared to genotype Phule madhur at harvest. However, the parching sorghum genotype Phule madhur showed significantly more number of leaves, leaf area plant-1 and leaf : stem ratio over genotype Gulbhendi Local-1. The parching sorghum genotype Phule madhur recorded higher grain recovery cob-1 and green hurda yield over the genotype Gulbhendi Local-1 and found significantly superior of parching sorghum found maximum in the genotype Gulbhendi Local-1. However, the genotype Gulbhendi Local-1 recorded maximum green fodder yield and found significantly superior over the genotype Phule Madhur. The highest benefit: cost ratio was observed in Phule Madhur (4.63:1) as compared to Gulbhendi Local-1 genotype. With regards to nitrogen management, application of 125% RDN ha-1 recorded maximum plant height, number of leaves, leaf area plant-1, leaf : stem ratio, dry matter plant-1 and stem diameter and was found significantly superior over 50 per cent RDN ha-1 through urea + 50 per cent RDN ha-1 through vermicompost, 100 per cent RDN ha-1 and 100 percent RDN ha-1 through vermicompost at harvest, respectively. Similarly, grain recovery panicle-1, green hurda yield and green fodder yield was maximum with application of 125% RDN ha-1 and found significantly superior over remaining nitrogen management treatments. Similarly, application of nitrogen 125% RDN ha-1 through urea recorded highest B:C ratio found significantly superior over different nitrogen management treatments i.e application of 50% RDN ha-1 through urea + 50% RDN ha-1 through vermicompost, 100% RDN ha-1 through urea and 100% RDN ha-1 through vermicompost, respectively.
