Efficacy of liquid, powder and gel-based rhizobium and RDN levels on growth and yield of groundnut

The field experiment was conducted during Zaid 2023 at Crop Research Farm, Department of Agronomy, SHUATS, Prayagraj (U.P). The experiment was laid out in Randomized Block Design with ten treatments which are replicated thrice on the basis of one year experimentation. The treatment combinations are T1 Powder based rhizobium + 50% RDN, T2 Liquid based rhizobium + 50% RDN, T3 Gel based rhizobium + 50% RDN, T4 Powder based rhizobium + 75% RDN, T5 Liquid based rhizobium + 75% RDN, T6 Gel based rhizobium + 75% RDN, T₇ Powder based rhizobium + 100% RDN, T8 Liquid based rhizobium + 100% RDN, T9 Gel based rhizobium + 100% RDN, T10 Control (20:40:40) are used. Results obtained that the application of Powder based rhizobium + 100% RDN recorded significantly higher Plant height (94.81 cm), Plant dry weight (47.65 g/plant), Significantly maximum number of pods/plant (49.20), Seeds/pod (3.00), Test weight (36.76 g), Seed yield (1966.22 kg/ha), were recorded with the treatment of Powder based rhizobium + 100% RDN.
