A field experiment was conducted during 2004_05 and 2005_06 at Agricultural Research Station, Durgapura, Jaipur to study the effect of NP fertilizers, vermicompost and sulphur on growth, yield attributes, yield and quality of clusterbean [Cymopsis tetragonoloba (L.) Taub.] and residual effect of NP fertilizers, vermicompost and sulphur on grain yield of succeeding wheat [Triticum aestivum (L.) emend. Bori and Paol.]. Application of NP fertilizers up to 75% of RDF (15 kg N + 30 kg P2O5/ha) recorded significantly higher seed yield, gum content and gum yield by 46.99 and 14.88, 11.06 and 5.26 and 63.53 and 20.29 per cent over control and 50% of RDF, respectively. Vermicompost application @ 2.0 t/ha significantly increased the yield attributes of clusterbean viz., pods per plant, seeds per pod, pod length and test weight and seed, straw and biological yields of clusterbean over vermicompost @ 1.0 t/ha. Further, the successive increase in sulphur up to 40 kg S/ha recorded significantly higher seed and straw yields of clusterbean. The combined application of NP fertilizers @ 75% of RDF and vermicompost @ 2.0 t/ha significantly improved the pods per plant and seed yield of clusterbean. The 100% of RDF, vermicompost @ 2.0 t/ha and sulphur @ 60 kg S/ha applied to clusterbean recorded significantly higher grain yield of succeeding wheat crop by 21.54, 12.04 and 21.09 over control, respectively.
