Response of Phosphorus Levels and PSB on Growth and Productivity of Kliarif Green Gram (Vigna radiata L.Wilczek) under Custard Apple (Annona squamosa) Based Agri-Horti-System

摘要

A field experiment was conducted to study the effect of phosphorus levels and PSB on growth and yield of kharif green gram (Vigna radiata L. Wilczek) under custard apple (Annona squamosa) based agri-horti-system during kharif season of 2009. Among different treatments, phosphorus levels with PSB application, 40 kg P_2O_5 / ha + PSB (T_7) treatment produced significantly highest in various growth parameters, viz., plant height, number of trifoliate leaves per plant, number of branches per plant, dry matter accumulation, yield components viz., number of pods per plant (20.87), number of grains per pod, pod length, test weight, grain yield (998.20 kg/ha) and straw yield (2893.0 kg/ha) and harvest index (34.12%) but at par with 30 kg P_2O_5 / ha + PSB (T_6) treatment.
