A research trial was carried out during kharif season of 2019-20, 2020-21 and 2021-22 at the AICRP on Soybean Farm, School of agricultural Sciences, Nagaland University to evaluate the production factors of soybean and their effects on growth, yield and economics. The experiment was laid out in Randomized Block Design with 7 treatments replicated thrice. The treatments comprised of T1-full package (seed treatment, seed inoculation, RDF, weed management, insecticide, ridge furrow), T2- full package - seed treatment, T3-full package - seed inoculation, T4-full package - RDF, T5-full package - weed management, T6-full package - insecticide and T7-full package - ridge furrow. Pooled results revealed that soybean grown with full package of practices gave highest growth and yield attributes and produced highest yield. Seed yield reduction of 91.24% and 69.90% with omission of weed management and RDF, was observed compared to full package of practice. Maximum yield gap was obtained with full package of practice excluding weed management and RDF. Partial factor productivity and Agronomic efficiency for NPK was higher with full package of practices.
