Influence of Biofertilizer and Zinc on Growth, Yield and Economics of Sorghum (Sorghum bicolor L.)

A field experiment was conducted during kharif 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to study the “Influence Biofertilizer and Zinc on growth, yield economics Sorghum (Sorghum bicolor L.)”. To Study treatment consisting three levels Azotobacter chroococcum viz. 10g/kg, 15g/kg 20g/kg 15kg/ha, 20kg/ha 25kg/ha. There were 10 treatments, each which replicated times laid out in randomized block design. The results showed that 9 [Azotobacter (20g/kg) + (25kg/ha)] recorded significant higher plant height (214.23 cm), dry weight (120.23 g), length ear head (25.44 seed (4310.02 kg/ha), straw (6810.02 kg/ha) harvest index (38.75 %) (25kg/ha)]. Similarly, maximum gross return (85752.38 INR/ha), net (58302.38 INR/ha) highest benefit cost ratio (2.12) also (25 kg/ha)] as compared other treatments.
