EFFECT OF PHOSPHORUS AND SPACING ON GROWTH AND YIELD OF GREENGRAM (Vigna radiata L.)

Abstract

A field experiment was conducted during Zaid season of 2019 at Crop Research Farm of SHUATS, Prayagraj (U.P). To study the “Effect of Phosphorus and Spacing on growth and yield of Greengram (Vigna radiata L.)”. The experiment consisted of 9 treatments and replicated thrice. Which includes three levels of phosphorus (30, 40 and 50 kg/ha) and three different Spacing levels of (20 cm x 15 cm), (30 cm x 15 cm) and (40 cm x 15 cm). Results revealed that application of 40 kg/ha Phosphorus + 20 cm x 15 cm recorded significantly maximum plant height (41.33 cm), dry matter accumulation (299 g/m 2 ) and crop growth rate (2.77 g/m 2 /day). As well as, the maximum number of branches per plant (4.82), number of nodules per plant (7.94) and number of pods per plant (18.89) were recorded with application of 40 kg/ha Phosphorus + 40 cm x 15 cm. Whereas, application of 40 kg/ha Phosphorus + 30 cm x 15 cm spacing significantly influenced higher Grain yield (1139.33 kg/ha) and Stover yield (2544.58 kg/ha). However, Net returns (Rs 52126.92/ha) and benefit cost ratio (1.76) was also obtained maximum with the application of 40 kg/ha Phosphorus + 30 cm x 15 cm. This experiment concluded treatment with 40 kg/ha Phosphorus + 30 cm x 15 cm was more productive as well as economic.
