Effect of Integrated Use of FYM and Phosphorus on Performance of Green Gram-Wheat Cropping System in Bundelkhand (UP)

A field experiment was conducted during 2009–10 and 2010–11 loamy sand soil of KVK farm Chitrakoot, Uttar Pradesh, to study the effect of integrated use of graded levels of P₂O₅ (i.e. 0,15,30,60Kg/ha) and four levels of FYM (i.e.0,3,6,12 t/ha). FYM was applied only to green gram in both the years. the seed yield of green gram increased significantly with the application of FYM up to 6 t.ha⁻¹ & fertilizer P up to 30KgP₂o₅ ha⁻¹. The study revealed that the dose of P can be reduced to half for obtaining optimum yield of green gram when 6 tFYM ha⁻¹ is conjointly applied. The yield of succeeding wheat crop in which previous green gram crop had FYM & application of 6 t. ha⁻¹ & fertilizer P up to 60 Kg P₂O₅. Residual effect of 12 tFYM &application of 60 KgP₂O₅ha⁻¹ produced the maximum wheat grain yield.
