Effect of iron, naphthalene acetic acid on growth and Economics of green gram

Abstract

A field experiment was conducted during kharif season of 2023 at Crop Research Farm Department of Agronomy on green gram. The treatments consisted of 3 levels of NAA (25, 50 and 75 ppm) and 2 level of Fe foliar Spray (0.5% and 2.5%) on 2 different growth stage (At 25 and 45 DAS). The experiment utilized a Randomized Block Design, comprising 10 treatments, each replicated three times. Application of 0.25% Fe foliar Spray (25 DAS & 45 DAS) + NAA: 50ppm (Treatment 6) recorded highest plant height (43.17 cm), maximum plant dry weight (14.82 g). The aforesaid treatment also recorded maximum gross return (INR 111465.46 /ha), net return (INR 78998.46/ha) and B:C ratio (2.43) was also recorded in the treatment 6.
