Abstract: A field experiment was conducted during kharif and rabi seasons of 2014-15 and 2015-16 at College Farm, College of Agriculture, Professor Jaya Shankar Telangana State Agricultural University, Rajendra Nagar, Hyderabad, Telangana to study the residual effect of integrated nutrient management, different dates of sowing and different fertilizer doses on production potential of succeeding beangal gram and French bean crop under pearl millet based cropping system. The three integrated nutrient management treatments viz., M₁-100% RDF, M₂-100% RDF + FYM @ 5 tons ha^-1 and M₃-100% RDF + Press mud @ 2.5 tons ha^-1 were given to pearl millet in kharif season as main plot treatments replicated thrice, during succeeding rabi season on the same field bengal gram and French bean were grown for which each main plot treatment was split into four sub plot treatments with different dates of sowing D₁ – After harvest of June 15^th sown pearl millet (September 24^th), D₂- After harvest of June 30^th sown Pearl millet (October 14^th), D₃- After harvest of July 15^th sown pearl millet (November 1^st) and D₄- After harvest of July 30^th sown pearl millet (November 15^th) and again each plot divided with four levels of recommended dose of fertilizers viz., S₁: 100% RDF to Bengal gram, S₂: 50% RDF to Bengal gram, S₃: 100% RDF to French bean and S₄: 50% RDF to French bean as a sub- sub treatments in strip- split plot design. The RDF (M₃-100% RDF + Press mud @ 2.5 tons ha^-1) applied to pearl millet reported the significant residual effect on growth, yield attributes, seed and haulm yields of succeeding begal gram and french bean crop followed by M₂-100% RDF + FYM @ 5 tons ha^-1. Among various dates of sowing, D₃ (after harvest of July 15^th sown pearl millet) recorded significantly higher seed yield followed by D_2, D₁ and D₄. Thus, application of 100% RDF significantly resulted in comparison to 50% RDF on growth, yield attributes, seed and haulm yields of both succeeding crops like bengal gram and french bean in pearlmillet based cropping sequence.
