Productivity and Profitability of Clusterbean as Influenced by Fertility Levels and Bio-inoculants

A field experiment entitled “Productivity and Profitability of Clusterbean as Influenced by Fertility Levels and Bio-inoculants” was conducted at Agronomy farm, S.K.N. College of Agriculture, Jobner (Rajasthan) during the Kharif, 2024 on loamy sand soil. The experiment was laid-out in factorial randomized block design replicated thrice consisting of 16 treatment combinations viz. four fertility levels [control, 40%, 80% and 100% RDF] and four bio-inoculants [control, Rhizobium, PSB and Rhizobium + PSB]. The results showed the significantly higher number of pods per plant (35.94), number of seeds per pod (8.51), test weight (29.14 g), seed yield (1495 kg/ha), haulm yield (3528 kg/ha) and biological yield (5023 kg/ha) along with net returns of ₹ 67,570/ha and B:C ratio of 3.09 in 100% RDF. Among different bio-inoculants, significantly higher number of pod/plant (35.22), number of seed/pod (8.30), test weight (29.01 g), seed yield (1489 kg/ha), haulm yield (3515 kg/ha) and biological yield (5003 kg/ha) where observed along with net returns of ₹ 67,556/ha and B:C ratio of 3.12 in Rhizobium + PSB. Treatment Rhizobium and PSB alone remained at par to each other but significantly higher than control. Results also showed that combined effect of 80% RDF with Rhizobium + PSB significantly increased the number of pods per plant, number of seeds per pod, test weight, seed yield, haulm yield and biological yield along with net returns and B:C ratio and it was equally effective with combination of 100% RDF with Rhizobium + PSB.
