The continuous cultivation focusing on high yield made the crop prone to various diseases, especially root rot. To evade the detrimental effects of agrochemicals on sensitive silkworms and environment, the importance was given to bio-control approach. In the present study, four bio-formulations of the actinobacterial isolate NM5 ( Streptomyces parvulus ) were prepared using three carriers: talc, rice husk ash and spent silkworm pupal powder. From the in-vivo study against combined inoculation of root rot pathogens, the lowest incidence of disease symptoms including wilting (25.45%) and rotting (20.91%) was observed in APNM5 (rice husk ash: silkworm pupal powder-1:1 ratio) treated plants which scored as mild to moderate infection. Untreated control was stunted with chlorotic leaves that defoliated prematurely with severe infection (76.25% wilting and 82.80% rotting). Moreover, in all NM5 treated saplings, as a result of defense action rotten root portions were stimulated to develop new healthy rigid roots. Biometric observations showed formulations had positive effect on plant growth parameters even in the presence of pathogens including higher leaf numbers (27.5), enhanced leaf area (67.96 cm 2 ) and yield (6 g plant -1 ), shoot length (44.56 cm) and weight 25.50 g plant -1 ), root length (33.67 cm), root weight (2.17 g plant -1 ), root: shoot ratio (0.08) than uninoculated saplings. Therefore, both the performance of potential isolate and effective utilization of agro-waste were enhanced by the nutrient based APNM5 bioformulation in an eco-friendly way.

From the findings of two years’ experiment, it can be noted that inoculation of Rhizobium significantly increased the number and dry mass of nodules (32.8 plant -1 and 35.8 mg plant -1 at 30 DAS), plant dry mass (26.8 g plant -1 ) and grain yield (861.3 kg ha -1 ) of black gram. Azotobacter chroococcum alone and with Rhizobium numerically favoured the nodulation (29.6 and 34.2 plant -1 respectively) in black gram. Rhizobium + A. chroococcum treatment produced significantly more plant dry mass (29.6 g plant -1 ) and grain yield (930.6 kg ha -1 ) of black gram over the uninoculated control (23.2 g plant -1 and 747.9 kg ha -1 respectively) and Rhizobium alone, respectively. Bacillus sp. in conjunction with Rhizobium were statistically comparable to Rhizobium alone inoculation in respect of nodule mass and grain yield. All the three inoculants together gave the 890.3 kg ha -1 black gram yield which was statistically comparable to Rhizobium + A. chroococcum in black gram. So, from the results of experiment, it can be concluded that dual inoculation of black gram seeds with Rhizobium + A. chroococcum promotes significant nodulation of black gram crop with in turn increases the plant biomass and seed yield of summer blackgram crop.
