term cropping in the tropics (Ipimoroti et al., 2002). Fuchs et al. (1970) reported that nutrients from mineral fertilizers enhance the establishment of crops while those from mineralization of organic manures promoted yield when both fertilizers were combined. Titiloye (1982) reported that the most satisfactory method of increasing maize yield was by judicious combination of organic wastes and inorganic fertilizers. It has been observed that addition of manure increases the soil water holding capacity and this means that nutrients would be made more available to crops where manures have been added to the soil (Costaet al., 1991). Murwira and Kirchman (1993) observed that nutrient use efficiency might be increased through the combination of manure and inorganic fertilizer. This study was therefore conducted to investigate the effects of varying rates of farmyard manure and inorganic fertilizers on the growth and yield of cucumber.
