Abstract
Findings derived from the present study suggest that Sorghum cultivars differed in their ability to respond to different fertilizer regimes. Not one cultivar consistently showed the same degree of response over all yield components measured. The most responsive cultivars for number of grains/head, straw yield, head weight, and Striga infestation were Karkatib, Dabr 1/1/1/1, Feterita, and T.U.B. 7 resp. Over all yield components measured maximum response to the different fertilizer regimes was realised at 215 kg N/ha. N-fertilization significantly increased host yields and significantly reduced Striga yields. Of all cultivars, Safra was the most efficient in allocating more nutrients to grain production than to straw. No consistent evidence was found to indicate that host responsiveness to nitrogen fertilization would invariably depress Striga infestations. Thus the hypothesis that N-fertilization significantly reduces a Striga attack is untenable as a general statement about all host cultivars.
