Abstract

Soils of Nagaland state are strong to slightly acidic in nature and deficient in available P. Low availability of phosphorus in these soils is due to fixation of P by Fe and Al oxides. The 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 nutrients uptake, qualitative properties and yield of soybean [Glycine max (L.) Merr.]. All the liming materials (WA @ 0.4 LR, PMS @ 0.4 LR and CS @ 0.4 LR and P levels ( 40, 60 and 80 kg P2O5 ha-1) significantly increased plant height, leave plant-1 , branches plant-1 , number of root nodules plant-1 at 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 plant height, number of ro

Conclusion

This study thus reveals that the application of calcium silicate (CS) @ 0.4 LR along with 80 kg P2O5 ha-1 was most effective towards the optimization of soybean yield with better quality, and to improve the qualitative of soybean and increase nutrient uptake followed by paper mill sludge (PMS) @ 0.4 LR along with 80 kg P2O5 ha-1 and wood ash (WA) @ 0.4 LR along with 80 kg P2O5 ha-1.
