Item Open Access Effect of Legume Inoculant and Biochar on the Growth, Nodulation and Yield of Soybean {Glycine max. L. Merrill)(Department of Agronomy, Nasarawa State University Keffi, 2021-10-25) Sodah, M.G.; Jayeoba, O.J.; Amana, Sani Mathew; Jibrin, Mangwa I.The experiments were conducted at the Teaching and Research Farm, Faculty of Agriculture, Shabu -Lafia Campus of Nasarawa State University, Keffi, during 2018 and 2019 cropping seasons to examine the effects of Legume Inoculant and Biochar on the growth, nodulation and yields of Soybean. The experiments were laid in Randomized Complete Block Design (RCBD). Biochar at the rates ofO, 4, 8 andl2 tons/ha was incorporated into the ridges before the Soybean seeds were planted as uninoculated (without legume inoculant) and inoculated (coated with legume inoculant) respectively. All data collected were subjected to analysis of variance (ANOVA) using GENSTAT Statistical Package while least significant different (LSD) was used to separate treatment means at 5% probability. The results revealed that inoculated plots recorded significantly (P<0.05) taller soybean plant, higher number of branches, nodules number per plant and grain yields (kg/ha) against uninoculated plots. The results also showed that biochar at the rate of 8 tons/ha produced significantly (P<0.05) tallest soybean plant, highest number of branches, nodules number per plant and grain yields (kglha) compared to other rates of biochar applied while the highest dose of biochar (12 tons/ha) applied did not necessarily influenced and increased Soybean growth and yield. Legume inoculant and biochar at the rate of 8 tons/ha is therefore recommended for sustainable Soybean in the study area.
