Trials were conducted in the screen house of Niger State College of Agriculture, Mokwa (09 degrees 18'N; 05 degrees 04'E) in the Southern Guinea Savannah agro-ecological zone of Nigeria during October-December, 2008 and January-March, 2009. The objective was to evaluate the effect of management of Striga hermonthica on sorghum (Sorghum bicolor) using Arbuscular mycorrhizal fungi and NPK fertilizer levels. The trials were laid out in split-split plot arrangement in a randomized complete block design. The main-plot treatments consisted of three sorghum varieties; SAMSORG 3, ICSVIII and SAMSORG 14 while the sub-plot treatments consisted of inoculations; Striga mixed with Glomus, Striga only and Glomus only as well as no inoculation control. The sub-sub-plot treatments were made up of NPK fertilizer levels; (100 kg N, 50 kg P2O5, 50 kg K2O ha(-1)), (50 kg N, 50 kg P2O5, 50 kg K2O ha(-1)) and (0 kg N, 0 kg P2O5, 0 kg K2O ha(-1)). The result obtained showed that sorghum variety SAMSORG 3 were taller, having more vigour and lower reaction to Striga parasitism which resulted in the crop producing higher dry matter compared to the other two varieties. The plots inoculated with Striga only supported shorter plants of sorghum varieties, higher vigour and lower reaction score to Striga compared to Striga mixed with Glomus. It is obvious in this study that the crop performance increases with increase in the rates of NPK fertilizer applied. |
