Abstract:
An experiment was laid out in a split plot design (SPD) with sixteen treatments and replicated thrice during the kharif season of 2018 and 2019 on different liming materials and phosphorus levels to evaluate the influence of different liming materials and levels of phosphorus on yield attributes, nutrients uptake, soil properties and yield of soybean [Glycine max (L.) Merr.]. Application of liming materials and P levels significantly increased pods plant-1, 100 seed weight, grain and stover yield. Interaction effect of liming material and P was also significant for number of pods plant-1, stover and grain yield. The highest yield was found with an application of calcium silicate @ 0.4 LR along with 80 kg P2O5 ha-1. Maximum uptake of N, P, K, S and Ca were found with CS @ 0.4 LR and 80 kg P2O5 ha-1.Their interaction was significantly influenced in nutrients uptake by soybean. Application of liming materials of CS @ 0.4 LR increased with pH-5.41 from the initial pH 5.31. The highest OC% was found in the plots receiving CS @ 0.4 LR (1.17%) and 80 kg P2O5 ha-1 (1.24%).The available N, P & exchangeable Ca2+ and Mg2+ in soil increased by application of liming materials and phosphorus and their interaction.
