Organic Manure & Biofertlizers: Effect on the Growth and Yield of Indian Mustard (Brassica juncea L.) Varieties

Abstract

A field experiment was conducted at the Research Farm of Sam Higginbottom Institute of Agriculture, Technology and Sciences, Allahabad during 2016-17 and 2017-18 to study the organic manures and biofertilizers: Effect on the growth and yield of Indian mustard varieties. The experiment was laid out in a randomized block design with three replications. The treatments consisted of five mustard varieties and 10 fertilizer treatments. The result of the study revealed that the variety Rani recorded significantly tallest plant highest, number of primary branches, number of siliquae/ plant, seeds per siliqua, seed and straw yields, whereas secondary branches were significantly highest with variety yellow Goldey. Amongst fertilizer treatments T7 (75% N through vermicompost + Azotobacter) produced significantly tallest plants, the highest number of primary and secondary branches/plant high yield attributing characters, seed and stover yield. The mustard variety Rani Supplied with 75% N through vermicompost + Azotobacter realised the highest gross, net returns and benefit cost ratio.
