Effect of organic sources of nutrient on growth, yield and quality of soybean (Glycine max L. Merill) in upland acid soils of Nagaland

A field experiment was conducted during Kharif season of 2016 and 2017 at the Experimental research farm of School of Agricultural Sciences and Rural Development, Nagaland University, Medziphema, Nagaland with the purpose of studying the effect of different organic nutrient combinations on growth, yield and quality of soybean. The experiment was carried out in soybean variety JS 97-52 with different sources of organic nutrient i.e FYM, Forest litter, Pig manure, Poultry manure and Vermicompost at varying amounts and combinations using a randomized block design. Application of Poultry manure @ 3 t ha-1 + Forest litter @ 0.25 t ha-1 produced maximum number of leaves, highest plant height and highest number of seed yield, stover yield, biological yield, protein and Oil content. Incorporation of Poultry manure @ 3 t ha-1 along with Forest litter @ 0.25 t ha-1 registered highest nutrient uptake and content in seed and stover and available nutrient in soil after harvest. The present study revealed that Poultry manure @ 3 t ha-1 + Forest litter @ 0.25 t ha-1 was the best nutrient management practice which improved growth, yield, nutrient uptake and available nutrient status of the soil after harvest of soybean.
