Abstract

The field experiment was conducted to study the effect of integrated nutrient management (INM) modules on green gram at instructional farm, Department of Agronomy, Faculty of Agriculture, MGCGVV, Chitrakoot, Satna (M.P.) during Kharif season of 2018-19. The experiment consisted of randomize block design having Factorial arrangement with three replications. In this experiment, 18 treatment combinations including three levels of nitrogen as F1- 75% RDF, F2- 100% RDF and F3- 125% RDF, two levels of Farm Yard Manure as O1- control and O2- FYM @ 5 t/ha, while three bio fertilizers rates were tested are B1- Rhizobium, B2- LMn 16 and B3-Rhizobium + LMn 16. Plant height, number of leaves per plant, number of nodules per plant, number of pods per plant, pod length, number of seeds per pod, test weight and Stover yield of green gram was not affected significantly due to chemical fertilizers, farm yard manure, bio-fertilizer and their interaction at all the growth stages. While seed yield was found non- significant due to farm yard manure and bio-fertilizer treatment. The seed yield of green gram was recorded significantly superior under treatment F3- 125 % RDF (535 kg/ha), followed by treatment F2- 100 % RDF (523 kg/ha), while the minimum was found in F1- 75 % RDF (496 kg/ha). Interaction effect between these treatments was found to be non- significant influenced of green gram, while seed yield of green gram was obtained significantly higher under treatment combination between F3- 125 % RDF X O1- control (548 kg/ha). Residual effect on succeeding mustard crop was not influenced by the treatments. Residual effects of different levels of chemical fertilizers, organic manure and bio-fertilizers on yield attributes on different yield attributes of mustard viz., number of siliquae per plant and number of seeds per siliqua was found to be non- significant. In application of chemical fertilizer maximum B:C ratio was found under F3- 125% RDF and F2¬¬- 100% RDF (1.91:1). It was noted that maximum B: C ratio was significantly obtained under O1- control (2.27:1). In application of bio-fertilizer maximum B:C ratio was noted under B3- Rhizobium + LMn 16 (1.91:1).
