Abstract

A study was conducted to assess the effect of liquid bio-inoculants on the agronomic traits of green gram. Field experiments were conducted on the Instructional-North farm of Karunya Institute of Technology and Sciences, Coimbatore, Tamil Nadu during the rabi season (2024) in a randomized block design. The experiment included five treatments [Absolute control, RDF, RDF + Rhizobium leguminosarum (TNAU14) in liquid formulation, RDF + phosphor bacteria in liquid formulation, RDF + Rhizophos in liquid formulation. Seeds were treated in accordance with the details given above and foliar application was done @ 1ml Lit-1 on 15th,30th and 45th DAS. From the results, a significant increase in the plant height (30.03 cm) dry matter production (1633.67 kg ha-1) and number of root nodules (65.70) at different growth stages were observed when compared to the absolute control. The yield parameters like pods plant-1 and seeds pod-1 were also increased. The treatments with mixed liquid bio-inoculant Rhizophos (T5) registered the highest seed yield and haulm yield of 730 kg ha-1 and 1816.67 kg ha-1 respectively. The results suggest that, application of liquid rhizophos through seed treatment and foliar spray significantly influenced the agronomic traits of green gram and the yield.

Keywords: Bioinoculants, foliar application, green gram, rhizophos, seed treatment, dry matter, yield, nodules
