Abstract
Field experiments were conducted under All India Coordinated Sorghum Improvement Project (AICSIP) at 6 lo- cations during rainy seasons of 2009 and 2010 in a split plot design having 3 fertility levels, viz., control (0:0:0 kg/ ha of N: P O :K O), recommended dose of nutrients-RDF (80:40:40 kg/ha of N: P O : K O) and 150% of RDF 2 5 2 2 5 2 (120:60:60 kg/ha of N: P O : K O) in main-plots, while 8 sorghum cultivars including 3 hybrids (CSH 14, CSH 16, 2 5 2 CSH 23) and 5 varieties (SPV 462, CSV 15, CSV 17, CSV 23, SPV 1616) constituted the sub-plot to find out their effects on productivity and nutrient-use efficiency in rainy-season grain sorghum [Sorghum bicolor (L.) Moench]. Results revealed that increasing levels of fertility up to 150% RDF significantly increased the grain yield (3.28 t/ha), nutrient uptake, net returns (25.97 103 /ha) and benefit: cost ratio (1.79) as compared to control. Hy- brids produced 20.6% higher grain yield over varieties. Among hybrids CSH 16 (3.07 t/ha) and among varieties SPV 462 (2.56 t/ha) produced the maximum grain yields. The nutrient-use efficiency (NUE) was higher in hybrids (6.66 kg grain/kg NPK) than the varieties (5.54 kg grain/kg NPK). Increasing fertility levels from 100% RDF to 150% RDF increased the NUE of all the test hybrids, but decreased the efficiency of varieties except CSV 17.
