A field experiment was conducted to study the residual effect of organics, Phosphorus levels and application of fertilizer levels on wheat under soybean-wheat cropping sequence in vertisols during 2010-11 and 2011-12 at College of Agriculture, Parbhani. The experiment was laid down with in split plot design with three sources of organic matter (0, FYM @ 5t ha-1 + PSB and Vermicompost (VC) @ 5t ha-1 + PSB ), four levels of P (0,30,60 and 90 kg P2O5 kg ha-1) and three fertilizer levels (0, 50% RDF and 100 % RDF) to wheat in soybean-wheat cropping sequence. The results on pooled basis indicated that available N,P and K kg ha-1 was significantly influenced due to residual effect of organics, P levels and application of fertilizer levels to wheat after soybean at 30, 60 DAS and at harvest. Among the organics residual effect of VC @ 5t ha-1 + PSB recorded maximum available N (170.29, 160.82 and 146.2503 kg ha-1), P (11.16, 10.43 and 10.30 03 kg ha-1) and K (710.13, 701.18 and 686.76 kg ha-1) at 30, 60 DAS and at harvest, followed by FYM @ 5t ha-1 + PSB. The residual effect of application of 90 kg P2O5 ha-1 to soybean showed maximum available N (169.82, 159.59 and 147.03 kg ha-1), P (11.00, 10.38 and 9.66 kg ha-1) and K (711.46, 693.21 and 688.46 kg ha-1) at 30, 60 DAS and at harvest. Application of 100 % RDF to wheat showed significant available N, P and K in soil over 50% RDF and Control. The maximum uptake of P kg ha-1, yield and quality parameters of wheat was recorded due to residual effect of VC @ 5t ha-1 + PSB, 90 kg P2O5 ha-1 and application of 100% RDF.
