Abstract

A field experiment was conducted during Zaid 2022 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P) to determine the “Influence of micronutrients and naphthalene acetic acid on growth, yield and economics of summer greengram (Vigna radiata L.)”. To study treatments consisting of three Micronutrients viz. Zn @ 100 ppm, Boron @ 100 ppm and Mn @ 50 ppm and three levels of Naphthalene acetic acid viz. 30, 40 and 50 ppm. There were 10 treatments, each of which was replicated three times and laid out in a random block design. The results showed that treatment 3 [Zinc (100ppm) + NAA (50ppm)] recorded significantly higher plant height (47.6 cm), higher number of branches/plant (9.00), higher number of leaves/plant (13.60), higher dry weight (7.40g), higher number of nodules/plant (7.6). Whereas, maximum number of pods/plant (29.00), maximum number of seeds/pod (10.27), higher test weight (29.40 g), higher seed yield (1.24t/ha), higher stover yield (2.73 t/ha) and higher harvest index (30.30 %) was recorded in treatment 3 [Zinc (100ppm) + NAA (50ppm)]. Similarly, maximum gross return (86,085.00 INR/ha), higher net return (58,674.00 INR/ha) and highest benefit cost ratio (2.14) was also recorded in treatment 3 [Zinc (100ppm) + NAA (50ppm)] as compared to other treatments.
