The organic-amendments viz., FYM, oil-cakes of mustard, cotton-seed and groundnut were incorporated in powdered form into the compost and casing-soil separately for the control of Aphelenchoides composticola infesting mushroom crop. The mustard oil-cake @ 5 to 10 g/kg of wet compost was most effective in increasing the yield of mushroom buttons and controlling the nematode. Incorporation of organic-amendments into the compost was better than that of their incorporation into the casing-soil. However, FYM proved least effective. Besides, incorporation of higher dose (10g/kg into compost or casing-soil) caused maximum mortality of the nematode and resulted in maximum yield of buttons. Both the doses of cakes, however, interacted differentially in causing the mortality of nematodes.
