Response of liming materials and phosphorus on growth and yield of soybean in a Dystrudept of Nagaland

A field experiment was conducted during the rainy (kharif) season of 2018 and 2019 on different liming materials and phosphorus to evaluate the influence of different liming materials and levels of phosphorus on growth attributes, yield attributes and yield of soybean [Glycine max (L.) Merr.]. All the liming materials (no lime, WA @ 0.4 LR, PMS @ 0.4 LR and CS @ 0.4 LR and P levels (0, 40, 60 and 80 kg P2O5 ha-1) significantly increased plant height, leave plant-1,branches plant-1, number of root nodules plant-1, root length and root dry weight at different crop growth stages at 30, 60 and 90 DAS. 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 the parameters plant height, number of root nodules plant-1, root length, 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.
