In the present study an attempt has been made to understand the effect of Ammonium nitrate and Urea on the rhizosphere mycoflora ofOryza sativa. The fertilizers' application to pot-soil planted with the paddy increased the microfungal population both in rhoizsphere and nonrhizosphere regions. Certain fungal species were stimulated by the fertilizers. 80 lbs/acre of amm. nitrate was most favourable for rhizosphere fungi where as 60 lbs/acre of urea proved the best.
