Effect of phosphorus and zinc levels on growth and yield of greengram (Phaseolus radiata L.)

Abstract

A field experiment was conducted during Zaid (summer) season of 2023 at Crop Research Farm Department of Agronomy. The experiment was laid out in a Randomized Block Design with 10 treatments and replication thrice. The treatments consisted of 3 levels of Phosphorus (40, 50 and 60 kg/ha) and 3 levels of zinc (2.5, 4 and 5.5 kg/ha) along with recommended doses of nitrogen, phosphorus and potash and a control (20-40-20 kg N-P-K/ha). Application of phosphorus at 60/ha in combination with Zinc at 5.5kg/ha (treatment 9) recorded maximum plant dry weight (9.72 g), more number of Pods/plant (9.64), Seeds/pod (10.49), test weight (39.95 g), and seed yield (1456.86 kg/ha).
