Effect of Integrated Use of Phosphorus Fertilizers and Biofertilizers on Growth and Yield of Groundnut (Arachis hypogaea L.)

Abstract

The present study highlight the effect of integrated use of phosphorus fertilizers and biofertilizers on growth and yield of groundnut (Arachis hypogaea L.). A field experiment was conducted during rabi, 2022 Wetland farm, S.V. Agricultural College, ANGRAU, Tirupati, Andhra Pradesh. Eight treatments and three replications made up the field experiment's randomized block design. The combined application of biofertilizers and phosphorus fertilizers had a substantial impact on the yield and growth of the groundnut crop. Most of the growth parameters and yield attributes viz., dry matter production, plant height, number of nodules plant-1, number of filled pods plant-1, number of ill-filled pods plant-1 were numerically highest with application of 75% RDP + liquid PSB + AM (T8) and 100 pod weight, 100 kernel weight, shelling percentage were recorded non-significant. Pod yield and kernel yield were recorded significantly highest with 75% RDP + liquid PSB + AM (T8) followed by 100% RDP + liquid PSB (T3).
