Influence of Phosphorus and potassium on Growth and Yield of Chick Pea (Cicer arietinum L.) under Prayagraj Condition

Abstract

The field experiment entitled was “Influence of Phosphorus and Potassium levels on growth and yield of chickpea” conducted during Rabi 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The soil of experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.36%), available N (171.48 kg/ha), available P (15.2 kg/ha) and available K (232.5 kg/ha). The experiment was laid out on Randomized Block Design with nine treatments each replicated thrice on the basis of one year experimentation. The treatments which are T1 : 20 kg/ha Phosphorus +10 kg/ha Potassium, T2 : 20kg/ha Phosphorus+20kg/ha Potassium, T3 :20kg/ha Phosphorus +30 kg/ha Potassium, T4 : 30 kg/ha Phosphorus +10 kg /ha Potassium, T5 : 30 kg/ha Phosphorus +20 kg /ha Potassium, T6 : 30 kg/ha Phosphorus +30 kg /ha Potassium, T7 : 40 kg/ha Phosphorus +10 kg /ha Potassium, T8 : 40 kg/ ha Phosphorus +20 kg /ha Potassium, T9 : 40 kg/ha Phosphorus +30 kg /ha Potassium are used. The results shown that the steady increase in growth attributes of Chickpea at 100 DAS viz., plant height (42.66 cm), Number of nodules per plant (6.33), Dry weight (29.17 g) were significantly higher in treatment 9 (40kg/ haphosphorus+30 kg/ha potassium). Also, treatment 9 with 40kg/ha phosphorus +30 kg/ha potassium recorded maximum number of Pods per plant (43.60), seeds per pod (1.93), Test weight (210.50 g), maximum Seed yield (2.49 t/ha), Stover yield (4.60 t/ha) and Harvest Index (34.99 %) compared to other treatments.
