Effect of Integrated Management of Phosphorus, Sulphur and Biofertilizers on Dry Matter Production, Yield and Nutrient Status of Pigeon pea (Cajanus cajan (L.) Millspough)

The present experiment was conducted at the Agriculture Farm of Shri Durga Ji Post Graduate College Chandeshwar, Azamgarh, Uttar Pradesh during Kharif season 2020 and 2021 to find out the effect of integrated nutrient management on growth, yield and nutrient status of pigeon pea (Cajanus cajan (L.) Millsp.). The experiment was laid out in Randomized Block Design (RBD) with three replications. There were 13 treatments combinations, consisted of phosphorus, sulphur and biofertilizer. Combined application of phosphorus, sulphur and biofertilizers significantly increased dry matter production, yield and nutrient status of pigeonpea over the control during both the years. The result revealed that higher grain yield (16.68 q ha-1) and stalk yield (53.22 q ha-1) of pigeon pea was obtained in plants treated with treatment T10(60 kg P2O5 ha-1 + 15 kg S ha-1 + Rhizobium + PSB) than that of control and other treatments.The results showed that the plots fertilized with a higher dose of phosphorus and a lower level of sulphur with biofertilizer under treatment T10 (60 kg P2O5 ha-1 + 15 kg S ha-1 + Rhizobium + PSB) had higher contents of N, P, and S (3.45, 0.449, and 0.204%, respectively) in grains and in stalks (1.59, 0.373, and 0.105%, respectively). Interaction effects (years ×treatments) were non-significant which implies interaction is absent indicated that treatments behave independently over years. The findings concludes that use of optimum fertilizer level along biofertilizers could able to enhance the performance of crop in terms of growth and yield.
