Abstract
Field experiment was conducted during kharif season of 2013 to evaluate the impact of nitrogen scheduling and cultivars on growth, yield and economics of sorghum (Sorghum bicolor L. Moench). The experiment comprised two cultivars (V1: CSH 16 and V2: CSV 20) and five nitrogen scheduling (N1: 50% at sowing as basal + 50% at 30 DAS, N2: 50% at sowing as basal + 25% at 30 DAS + 25% at boot-leaf stage, N3: 25% at sowing as basal + 50% at 30 DAS + 25% at boot-leaf stage, N4: 25% at sowing as basal + 50% at 30 DAS + 15% at boot leaf stage + 10% at grain filling stage, N5: 25% at sowing as basal + 45% at 30 DAS + 5% foliar spray at 45 DAS + 15 % at boot leaf stage + 10% at grain filling stage) with three replications were assigned in factorial randomized block design. The results revealed that the cultivar 'CSH 16' recorded significantly higher chlorophyll content (3.44 mg g–1), dry matter accumulation in panicle (3.11 and 53.81 g at 60 DAS and at harvest, respectively), grain yield (1521 kg ha–1) and N uptake (74.54 kg ha–1) while significantly higher dry matter accumulation in leaves (13.31 g at 60 DAS and 21.48 g at harvest) and stem (12.02 and 23.65 g at 60 DAS and at harvest, respectively), stover yield (11141 kg ha–1) and K uptake (181.45 kg ha–1) were recorded in cultivar 'CSV 20'. For sorghum, application of nitrogen in N2 schedule significantly improve chlorophyll content (3.43 mg g–1), dry matter accumulation in leaves (14.30 g at 60 DAS and 21.13 g at harvest), stem (12.38 at 60 DAS and 23.70 g at harvest) and panicle (3.36 and 53.32 g at 60 DAS and at harvest, respectively), grain yield (1613 kg ha–1), stover yield (11811 kg ha–1) , total N, P, K uptake, net returns (` 19487 ha–1) and B:C ratio (1.95) over rest of the nitrogen scheduling treatments.
