Effect of different levels of phosphorus and dates of sowing on growth and yield of green gram (Vigna radiata L.) under climatic condition of Allahabad

Abstract

A field experiment was conducted during the Kharif season 2015 at the Crop Research Farm, Department of Environmental Science, SHIATS, Allahabad (U.P.) to concluded the experiment on the title effect of different levels of phosphorus and dates of sowing on growth and yield of green gram (Vigna radiata L.) under climatic condition of Allahabad in factorial Randomized Block Design with nine treatment combinations and replicated thrice. The results revealed that highest plant height (75.81 cm), number of branches (4.00), number of nodules (65.27). Yield and yield attributes viz. number of pods plant-1 (31.53), Test weight (44g), seed yield (1497 kg ha-1), stover yield (2920 kg ha-1), harvest index (42.45%) were highest recorded in treatment T3 (75 kg phosphorus ha-1+15 July DOS). Treatment combination T7 (25 kg phosphorus+05 August DOS) require more GDD to reach flowering (959.00) and maturity (1540.70).
