The experiment was conducted both in the laboratory and glasshouse of the Department of Plant Pathology, BAU, Mymensingh during the period of March to July, 2001. Mixed inocula of Meloidogyne javanica and Sclerotium rolfsii in five different treatments including control were tested on the growth, yield, galling incidence and development of the nematode in soybean. Maximum length of shoot and root, fresh weight of shoot and root with nodules, number of pods, number of nodules and yield per plant were observed with the control treatment. Progressively higher galling incidence and higher number of adult females and juvenile populations of M. javanica correspondingly with lower plant growth, nodulation and yield per plant were recorded from lower to higher levels of inocula ranging from 4-10 egg masses of M. javanica with 0.025-0.1% w/w of S. rolfsii. Galling incidence was negatively correlated with plant growth, nodulated and yield of soybean.
