Influence of Pre-sowing Seed Treatment with Bio – fertilizers on Plant Growth and Yield Attribute Traits of Mustard (Brassica nigra L.)

A set of thirteen treatments including control of seed treatments of mustard (Brassica nigraL.) with various biofertilizers were used to evaluate the effect of different pre sowing seed treatments of bio-fertilizers on growth,yield and yield attributing traits of mustard. The treatments were evaluated in a Randomized Block Design with three replications during the rabi season, 2021-22. The present investigation was carried out at the Field Experimentation Centre of Department of Genetics and Plant Breeding, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Naini, Prayagraj, U.P. during rabi 2021. at Naini Agriculture Institute,Naini. The data were recorded from five randomly selected plants for each treatments in all the replications for twelve characters. Analysis of variance showed significant differences among the seed treatments for all characters indicating that the seed treatment with biofertilizers has adequate variability to support the improvement the seed yield of mustard. It is concluded that all the characters under study were significantly affected by the influence of the application of biofertilizers. Among all the biofertilizers used under the study, seed treatment with the application of vermiwash at 12% for a duration of 6 hours and observed rapid increase in field emergence, plant height, seeds per siliqua and yield characteristics.
