Effect of organic manures and spacing on growth and yield of greengram (Vigna radiata L.)

Abstract

The field experiment was conducted on Greengram during Kharif season of 2024 at Crop Research Farm, Department of Agronomy, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (U.P.). To study the “Effect of Organic manures and Spacing on growth and yield of greengram (Vigna radiata L.)”. The experiment was done under Randomized Block Design with nine treatments and replicated thrice. The results revealed that treatment 6 [Poultry manure (8.7q/ha) + 25 cm x 25 cm] was found to be more desirable with higher growth parameters viz, significantly taller plant height (43.87 cm), maximum number of branches/plant (7.67) and higher plant dry weight (7.75 g) and yield attributes and yield namely maximum number of pods/plant (14.80), maximum number of seeds/pod (14.13), higher seed yield (1300.00 kg/ha) and higher stover yield (4533.33 kg/ha). However, the maximum gross return (161165.99 INR/ha), net return (119665.99 INR/ha) and benefit cost ratio (2.88) were also recorded in treatment 6 [Poultry manure (8.7q/ha) + 25 cm x 25 cm] was found to be productive and also economically feasible.
