Influence of Biofertilizers and Zinc on Growth and Yield of Mustard (Brassica juncea L.)

A field experiment was conducted during Rabi 2021-2022 to study the “Effect of biofertilizers and zinc on growth and yield of mustard (Brassica juncea)’’, at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). Mustard variety of Varuna T-59 was used with biofertilizers like Azotobacter and PSB along with different levels of zinc at 5, 10 and 15 kg.ha1. There were 9 treatments each replicated thrice. The result showed that growth and yield parameters viz., plant height (191.33 cm), no of branches (10.40), Plant dry weight (34.99g), Number of siliquae/plant (283.93), Number of seeds/siliqua (14.99), seed yield (2.23t.ha1) and stover yield(4.90t.ha1) were recorded highest in treatment 9 with the application of Azotobacter 10 g/kg1 seeds+ PSB 10 g/kg seeds + Zinc 15 kg.ha1. Gross return (1,33,800.00 INR/ha), Net return (93,921.00INR /ha). B:C ratio (2.35) were recorded superior with application of Azotobacter 10 g/kg1 seeds+PSB 10 g/kg seeds + zinc 15 kg.ha1.
