Effect of fertility levels and bioinoculants on productivity, profitability, quality and nutrient acquisition of clusterbean (Cyamopsis tetragonoloba)

Abstract

A field experiment conducted during the rainy (kharif) season 2008 at Jobner, Rajasthan, to evaluate that effect of fertility and bioinoculants on productivity, nutrient uptake and quality of clusterbean [Cyamopsis tetragonoloba (L.) Taub.]. The application of 75% recommended dose of fertilizer along with seed inoculation with Rhizobium significantly resulted in more number of effective nodules/plant (19.4), nodules dry weight/plant (17.8 mg), clusters/ plant (17.5), seed (1.10 t/ha) and stover yield (2.99 t/ha) and profitability over seed inoculation of PSB, Rhizobium and control. Nitrogen and phosphorus uptake by seed and stover were also significantly higher with 75% recommended dose of fertilizer along with Rhizobium over PSB, Rhizobium and control. Significantly higher protein content (27.81%) was recorded with application of 75% recommended dose of fertilizer along with Rhizobium over PSB, Rhizobium and control. Gum content (29.20%) was also higher with application of 75% recommended dose of fertilizer along with Rhizobium. © 2014, Indian Society of Agronomy. All rights reserved.
