Abstract
The present study aimed to investigate the impact of seed-borne mycoflora on soybean (Glycine max L.). Seed germination and subsequent seedling vigour are important factors for influencing crop establishment and yield potential. Six varieties of soybean seed samples viz. JS 95-60, JS 97-52, RSC 10-46, RSC 10-71, CG Soya-1 and seven seed-borne mycoflora viz. Fusarium spp., Alternaria spp., Colletotrichum spp., Cladosporium spp., Macrophomina spp., Penicillium spp. and Trichoderma spp. were selected for the experiment. A pot experiment was conducted to study the effect of seed-borne mycoflora on seed germination and seedling vigour of soybean. The results revealed that, among seed inoculation techniques maximum reduction in seedling vigour index over control was observed in Colletotrichum spp. (27.24%) inoculated seedlings and overall increased seedling vigour of soybean varieties was observed in Trichoderma spp. (26.52%) inoculated seedlings. Among soil inoculation techniques maximum reduction in seedling vigour index over control was observed in Macrophomina spp. (38.41%) inoculated seedlings and overall increased seedling vigour of soybean varieties was observed in Trichoderma spp. (24.40%) inoculated seedlings.
