Impact of nutrient management system on growth, yield and quality of Indian mustard (Brassica juncea L.) cv. Rani variety

Abstract

A field experiment was conducted at the central Research Field of Sam Higginbottom university of Agriculture, Technology and Sciences, Prayagraj during 2016-17 and 2017-18 to study the’’ Impact of nutrient management system on the growth, yield and quality of Indian mustard (Brassica juncea L) cv. Rani variety’. The experiment was laid out in a factorial randomized block design with three replications along inorganic, organic and biofertilizers with 10 different treatment combinations. The result of the study revealed that the T6 (50% N through vermicompost + Azotobacter) exhibited significantly higher in plant growth, yield, oil yield and quality parameters viz., Plant height, (cm), Number of primary branches/plant, Number of secondary branches/plant, First flower appearance, 50% flowering DAS and Flower appearance (DAS) Number of Siliquae/plant, Number of seeds/Siliquae 1000-seed weight (g), Seed yield (q/ha), Stover yield (q/ha), Harvest index (%), N content in seed (%), Protein content in seed (%), Protein yield (Kg/ha), Oil content (%), Oil yield (kg/ha), Palmitic acid (%), Stearic acid (%), Oleic acid (%), Linoleic acid (%), Linolenic acid and Arachidic acid. It was also evident from the results that the plant growth, yield, oil yield and quality parameters as recorded by different treatments during 2016-17 were comparatively lower than recorded during 2017-18.
