The application of tebuconazole at all doses tested in this study showed a significant (p 6 0.05) phytotoxicity to greengram plants and severely affected the dry matter accumulation, nitrogen fixing determinants: nodule numbers, nodule dry biomass and Lb, nutrient-uptake, and yield and quality of grains. The doses of fungicide higher than the recommended one had displayed more toxicity to greengram plants.
