Abstract
It is an established fact that temporary waterlogging occurs at first irrigation to wheat crop in rice-wheat cropping system. This is also true in saline sodic soils. Wheat crop becomes pale yellow just after first irrigation resulting in severe reduction in growth and yield. This study was planned to address this problem by various management strategies like irrigation at 25 days after sowing (DAS) without fertilizer, irrigation at 25 DAS + 120110-70 NPK kg ha -1 , irrigation at 25 DAS + 120-110-70 NPK kg ha -1 + 25 kg sulphuric acid per hectare, irrigation at 25 DAS+ 120-110-70 NPK kg ha -1 +12 kg sulphuric acid per hectare and irrigation at 40 DAS +120-110-70 NPK kg ha -1 . A saline sodic field {pHs =8.92, ECe =5.70 (dS m -1 ) and SAR=23.71 (mmol L -1 ) 1/2 } was selected. Maximum grain yield (3.01 t ha -1 ), number of tillers (437 m -2 ), 1000-grain weight (35.43 g) and number of grains spike -1 (40) were produced with the application of 120-110-70 NPK kg ha -1 + 25 kg ha -1 sulphuric acid at first irrigation applied 25 days after sowing in saline sodic soil.
