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

Abstract

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