Yield and economics of moth bean [Vigna aconitifolia (Jacq.) Marechal] as influence by the levels of phosphorus, spacing and manures

A field experiment was conducted during kharif 2018 at Central Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj, (U.P.). The soil experimental plot sandy loam in texture, nearly neutral reaction (pH 6.7), low organic carbon (0.35%), available N (230 kg ha-1), P (20 ha-1) and K (189 ha-1). laid out Randomized Block Design with factorial concept. There were 13 treatments including 12 treatment combinations three levels phosphorus, two spacing organics one control. Result show that higher dose phosphorus recorded significantly yield parameters viz., plant pods per (28.14), grains pod (4.57) Test weight (27.54 g).
