N.BabatundeF. E.TenebeV. A.3200723An experiment was conducted during the 2002 and 2003
cropping seasons on a striga infested field at Bauchi in the Northern
Guinea Savannah ecological zone of Nigeria in order to evaluate the effect
of some cowpea varieties and planting patterns on striga suppression.
Sorghum variety (SAMSORG 14) was grown in mixture with three cowpea varieties
(Kano 1696, Yaro da kokari and IT89KD-288) and three planting patterns
(alternate ridge, 1:1 and 2:1 sorghum: cowpea combination ratio on same
ridge). These treatments were factorially combined in a randomized completely
block design and replicated three times. Sorghum intercropped with cowpea
variety Kano 1696 in alternate ridge significantly reduced striga density
and striga dry matter production. The same factorial combination also
gave the highest percent nitrogen (N) in sorghum grain, total N uptake
by sorghum, cowpea and the highest contribution of symbiosis to N uptake
of sorghum. It could be suggested from this study that any striga control
package to be developed for small scale farmers around the study area,
should consider intercropping sorghum/cowpea as a central focus. However,
screening of more cowpea varieties should be taken into cognizance in
order to determine the most suitable variety for reducing striga seed
bank.]]>Adagba, M.A., S.T.O. Lagoke and A. Usman,2002Striga hermonthica in upland rice: Influence of upland rice varieties and rates of nitrogen fertilizer.]]>33119127Aflakpni, G.K., S.
