Influence of Nitrogen 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 Nitrogen and Zinc on Growth, Yield and Economics of Sorghum (Sorghum bicolor L.)”. To Study treatment consisting of three levels of Nitrogen viz. 60, 80 and 100 kg/ha and three levels of Zinc viz. 15, 20 and 25 kg/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 [Nitrogen 100 kg/ha + Zinc 25 kg/ha] recorded significant higher plant height (238.83 cm), higher dry weight (122.37 g), higher length of ear head (27.51 cm), higher seed yield (4430.43 kg/ha), higher stover yield (7246.58 kg/ha), higher number of grains/head (981.34) and higher harvest index (38.75 %) was recorded in treatment 9 [Nitrogen 100 kg/ha + Zinc 25 kg/ha]. Similarly, maximum gross return (1,46,993.65 INR/ha), maximum net return (99,186.03 INR/ha) and highest benefit cost ratio (2.08) was also recorded in treatment 9 [Nitrogen 100 kg/ha + Zinc 25 kg/ha] as compared to other treatments.
