Effect of phosphorus management with bio-agents on yield and yield attributes of groundnut (Arachis hypogea L.)

A field experiment entitled “Effect of phosphorus management with bio-agents on growth and yield of groundnut (Arachis hypogea L.)” was carried out during rabi, 2020 at Wetland Farm, S.V. Agricultural College, Tirupati campus (under the judicatory of Acharya N.G. Ranga Agricultural University). The experiment was laid out in a randomized block design with nine treatments. Phosphorus management practices were significantly influenced the growth and yield of groundnut crop. The highest pod yield and number of filled pods plant-1 was recorded with the application of 100% RDP + Liquid PSB + VAM (T7) whereas highest haulm yield was recorded with the application of 125% RDP + Liquid PSB + VAM (T9). 100 pod weight, 100 kernel weight, shelling percentage were non significantly influenced by the application of inorganic phosphorus, liquid PSB and VAM.
