Repercussion of Seed Treatment with Bio-fertilizers, Bio-stimulants, Botanicals on Plant Growth & Yield Attributes Traits of Black Mustard (Brassica nigra L.)

The present experiment was conducted in field at Department of Genetics and Plant Breeding. Naini Agriculture Institute, SHUATS, UP. to investigate the " Repercussion of seed treatment with bio-fertilizers ,bio- stimulants , botanicals on plant growth & yield attributes traits of black mustard (Brassica nigra L). The experimental material comprised of Thirteen (12+1) treatments including control. The seed of mustard variety NDR 8501 were treated with three different concentrations of each biofertilizer viz., Neem leaf extract, Tulasi leaf extract, Rhizobium,Vermiwash for a duration of 8hours. The experimental was conducted in Randomized Block Design (RBD) with two replications during the rabi season, 2021-22. The data were recorded from five randomly selected plants for each treatments in all the replications for thirteen 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 15% for a duration of 8 hours gave the significant difference in comparision to other treatments as well as over the control.
