Effect of fertility levels and bio-fertilizers on productivity of mungbean [Vigna radiata (L.) Wilczek]

Abstract

A field experiment was conducted at Agronomy farm, School of Agriculture, Suresh Gyan Vihar University, Jaipur (Rajasthan) during kharif, 2022 on loamy sand soil with objective to study the response of mungbean to varying fertility levels and bio-fertilizers. The sixteen treatment combinations consisting of four each of fertility levels (Control, 50, 75 and 100% RDF) and bio-fertilizers (Control, Rhizobium, PSB and Rhizobium + PSB) were tested in randomized block design with three replications. Application of rhizobium and PSB was significantly increased the number of pods/plant, seeds/pod, test weight, seed (1053 kg/ha), straw (2054 kg/ha) and biological yield (3106 kg/ha) were also obtained under rhizobium and PSB that were 20.20, 15.78 and 17.25 percent more than over control, respectively and net returns (Rs 53772/ha) and B:C ratio (2.73) over control and rhizobium alone.
