Abstract

Field experiment was conducted to investigate effect of co-inoculants Rhizophos in liquid formulation on the agronomic traits of black gram (Vigna mungo L.). The treatments such as RDF (Recommended dose of fertilizer) + rhizophos in liquid formulation (T5), RDF + phosphobacteria in liquid formulation (T4), RDF + Rhizobium leguminosarum (TNAU14) in liquid formulation (T3), RDF (T2) and absolute control (T1) were imposed in a Randomized Block Design with four replication each. Seeds were treated accordingly with the treatments and foliar application was done at 1ml.L-1 on 30, 45 and 60 DAS. Among the treatments, foliar spray of Rhizophos @ 1 ml.L-1 exhibited profound effect in improving the growth and yield attributes. The result demonstrates that RDF + rhizophos in liquid formulation recorded the highest yield of (750 kg.ha-1) over the control (483 kg.ha-1). The results showed that, application of co-inoculant rhizophos through seed treatment and foliar spray significantly influenced the agronomics traits and yield of black gram over individual treatment and recommended dosage alone.

Keywords: Foliar spray, bio-inoculant, Black gram, yield, phosphobacteria, rhizophos, seed treatment
