This investigation aimed to see the effect of saprophytic fungus (Arachniotus sp.) and organic matter (wheat straw) at four N levels (0, 40, 80 and 120 mg/kg soil) under greenhouse conditions. The treatments were tested on maize fodder and their residual effect was also seen on two subsequent crops (wheat and maize). Nitrogen (4 levels) was applied to all three crops. Maize fodder yield of first crop was not affected by nitrogen, wheat straw or fungus plus wheat straw applications. Wheat straw and fungus plus straw had no residual effects on wheat grain yield as well as protein contents. Higher N application improved grain/straw yields, protein content and tillering of wheat. When residual effect was tested on second crop (maize), its fodder yield and protein contents were not affected. Rather they were decreased. The data concluded that results were very inconsistent and fungus inoculum did not enhance N-use efficiency alone or in combination with N application.
