“…The residual N2 content of soil was estimated by Kjeldahl method (Ferrai, 1960;Subba Rao, 1979) from the soil obtained upto the depth of 6 cm. After 75 days of incubation of G. max chlorophyll content was measured by the method performed by Arnon (1949) and Witham et al (1971).…”

Glycine max-Rhizobium interaction is a well known symbiotic association occurring in nature and responsible for biological nitrogen fixation. Thiram a well-known fungicide has been in practice as seed dressing in order to prevent fungal colonization. In the present study the effect of various thiram concentrations is investigated. Thiram concentration beyond 500 g/ml was observed to be highly toxic with respect to plant growth factors and rhizobial infection to the G. max. The nodulation, nodule dry weight, nitrogenase activity were observed to be maximum at 100 g/ml of thiram. The study is useful in determining the threshold concentration of fungicide for soybean seed dressing for effective nitrogen fixation and crop yield.
