Abstract:
A field experiment was conducted to find out the Phosphorous and drought mitigating strategies on growth and yield of Chickpea (var. RVG-202) with the different levels of Phosphorous (40, 50, 60 P₂O₅ kg/ha) and with the application of Drought mitigating strategies applied at pre-flowering and pod formation stage)respectively, at Crop Research Farm, Department of Agronomy, Faculty of Agriculture, SHUATS, Prayagraj, Uttar Pradesh The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%),available N (225 kg/ha), available P (19.50 kg/ha) and available K (92.00 kg/ha). The experiment was laid out in Randomized Block Design, with ten treatments consists of viz., 1: Control(RDF) 2: P₂O₅ 40 kg / ha + 1% KCl spray 3: P₂O₅ 40kg/ha + 0.5%sodium selenite spray 4: P₂O₅ 40 kg/ha+1% KCl + 0.5% sodium selenite spray 5: P₂O₅50 kg / ha+1% KCl spray 6: P₂O₅ 50kg/ha+2%Urea + 0.5% sodium selenite spray 7: P₂O₅50 kg/ha + 2% Urea + 1%KCl +0.5%sodium selenite spray8: P₂O₅60kg/ha + 25kg ZnSO₄/ha + 1% KCl spray 9: P₂O₅ 60kg/ha + 25kg ZnSO₄/ha + 0.5%sodium selenite spray10: P₂O₅ 60kg/ha+25kg ZnSO₄/ha + 1% KCl +0.5%sodiumselenitespray in the rabi2021. Results obtained that there was significant increase in growth parameters viz., Plant height (60.36cm), Number of Nodules/Plant (38.60 at 60DAS), Dry weight (26.56g)and yield attributes viz., Seed yield (2332.00 kg/ha), Straw yield (4571.33 kg/ha) and Harvest index (33.51%) were recorded with the application of P₂O₅ 60kg/ha + 25kg ZnSO₄/ha + 1%KCl +0.5%sodium selenite spray. Therefore, it is concluded that the application of P₂O₅ 60 kg /ha+ 25 kg ZnSO₄/ ha + 1% KCl + 0.5% sodium selenite spray was more productive and economically feasible.
