Abstract

Effects of nitrogen on stem borer damage in a sorghum/millet m ixture were investigated in Nigeria. Millet and sorghum grain yield as well as stem borer infestation were not significantly influenced by rate and time of nitrogen application. Borer (Acigona ignefusalis) infestation on millet was very severe in 1984, resulting in total crop failure. In 1985, millet produced grains because of lower borer infestation and damage; the yield of sole millet was thrice that of millet in mixture, whereas the sole crop density was twice that in the mixture. Unlike millet, sorghum produced grains in 1984 despite severe damage by Busseola fusca. Sole sorghum yielded five times the mixture in 1984 but two and a half times in 1985. Borer damage was generally more severe in the mixture.

Résumé

Les effets de l'azote sur le dommage du foreur des tiges dans l'association sorgho'mil ont été examinés au Nigeria. Le rendement en grain du mil et du sorgho aussi bien que l'infestation par le foreur des tiges n'etaient pas influencés significativement par le taux et le temps d'application de l'azote.

Infestation sur le mil par le foreur (Acigona ignefusalis) etait très sévère en 1984, resultant à l'échec total de la culture. En 1985, le mil à produit des grains à cause de l'infestation moindre et le dommage, le rendement du mil en monoculture etait le triple de celui du mil en association alors que la densité de la monoculture etait le double de celle de la culture en association. A la difference du mil, le sorgho a produit des grains en 1984 en dépit de dommage sévère par Busseola fusca. La monoculture du sorgho a donné un rendement cinq fois plus que l'association en 1984 mais deux fois et demi en 1985. Le dommage du foreur etait en général plus sévère dans l'association.
