Effect of fertility levels and bioinoculants on growth, productivity and economics of cluster bean (Cyamopsis tetragonoloba)

Abstract

A field experiment was conducted at research farm of SKN College of Agriculture, Jobner, Rajasthan to assess the effect of fertility and bioinoculants on growth, yield and economics of cluster bean (Cyamopsis tetragonoloba L.). The results revealed that application of 75% recommended dose of fertilizer along with Rhizobium inoculation recorded higher growth (plant height, branches/ plant, dry matter accumulation/plant and nodules/plant); yield attributes (pods/plant, seeds/pod and 1000-seed weight) seed and stover yields, gross returns (25.05 × 103 Rs./ha), net returns (13.63 × 103 Rs./ha) and B:C ratio (1.19) as compared to control and phosphate solubilizing bacteria (PSB) inoculation and remained at par with all other treatment combination. So, it was concluded that use of 75% RDF along with Rhizobium may be recommended for obtaining the higher yield of Cluster bean in the region.
