Abstract The field experiment was conducted at Education and Research Farm, Department of Agriculture Botany, College of Agriculture, Dapoli during rabi 2017–2018 to study effect of biocontrol agents on physiochemical aspects of Lablab purpureus L. The experiment was laid out in randomized block design with seven treatments in three replications. The seven treatment were T0 RDF only, T1 Rhizobium treatment, T2 RDF + T1, T3 Tricoderma viride (4ml/lit) + T1, T4Pseudomonas fluorescence (4ml/lit) + T1, T5Bacillus subtilis (4ml/lit) + T1, T6-Paceilomyces lilacinus (4ml/lit) + T1 respectively. Different bio control agents were applied through foliar spray at 2nd and 4th week after sowing. Data were collected on plant height, number of branches, number of leaves, days to 50% flowering, days to maturity, number of pods per plant, number of pods per plant, no of grains per pod, pod yield per plant (g), pod yield per plot (kg), grain yield per plant (g), grain yield per plot (g) at the interval of 30, 60, 90 DAS and at physiological maturity. Growth period of the crop significantly reduced with the application of bio control agent. The treatment paceilomyces lilacinus Bacillus subtilis Pseudomonas fluorescence and Trichoderma harzianum were superior in physiological attributes and growth parameter among all the treatments. So there is a need of further research work on different bio-control agents to assess their potential for developing smart green technologies in agriculture. Physiological role of biocontrol agent in mitigating the morphological related consequences of crop are discussed. Top Keywords Biocontrol agent, Morphological, Yield attributes. Top |
