Effect of organic manure and biofertilizer on Growth and yield of brown mustard (B. juncea subsp. integrifolia var. crispifolia)

The study was conducted at Department of Horticulture, Sikkim University, Gangtok, Sikkim during 2020–2021 with an objective to observe impact of organic manure and biofertilizers on growth and yield of brown mustard. The experiment had 7 treatments and 3 replications and statistical design used was Randomized Block Design. The best results were observed in treatment T6 (FYM 100%) + Azospirillium @5kg/ha) in terms of leaf length, leaf width, plant girth, number of leaf/plant, leaf weight, fresh weight of plant, dry weight of plant, leaf area index, leaf NPK content, germination percentage, root length. The second best treatment in this study was T3 (FYM 100%+ Azotobacter @500 ml/ha). The study is helpful in improvement of production of brown mustard.
