Abstract

Field experiments were carried out at Research Farm, ICAR Sikkim Centre, Tadong during two consecutive Rabi seasons of 2012 and 2013 to determine the effect of different microbial inoculants on selected soil biological properties, growth, yield, and quality of common buckwheat, and then identify the best inoculant for application for local common buckwheat production in hilly ecosystem of North-East India. The results indicated that seed inoculants applied to common buckwheat effectively increased plant growth, chlorophyll content (SPAD), yield attributing characters, total phenolic and flavonoid content, grain yield, and soil biological properties. Among the different inoculations, combined application of Azotobacter spp. and Azospirillum spp. was found most efficient and resulted in maximum values of plant growth parameter, yield attributing characteristics, grain yield (1.23 Mg/ha), soil microbial biomass carbon (SMBC) and dehydrogenase activities at all the growth stages of common buckwheat.

Key words: Buckwheat, dehydrogenase activities, flavonoid content, phenolic content, microorganisms, yield.
