Abstract:
Trials were conducted in the screen house of Niger State College
of Agriculture, Mokwa (09°18’N; 05°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.
