Weed dynamics and yield of soybean as influenced by integrated nutrient and weed management practices

Abstract

In the year 2017 and 2018, a field trial on soybean was performed in the kharif season. The application of 75% RDF + 25% organic through farmyard manure + Phosphate solubilizing bacteria treatment was found showing highest plant height (47.39), number of primary branches (25.04), plant dry matter accumulation (25.04 g plant -1 ), seed yield (1.63 t ha -1 ), and stover yield (2.27 t ha -1 ). On the other hand, treatment 50% RDF+50% organic through Rhizobium + Phosphate Solubilizing Bacteria registered minimum density as well as dry weight of weeds. Regarding weed management practices, minimum weed density and dry weight; and maximum soybeans’ growth and yield were registered under three hand weedings (hand weeding at 15, 30, 45 DAS).
