 en Estimation of the Fertilizer Response of Maize and Bean Intercropping Using Sole Crop Response Equations
Wortmann, C.S.; Schnier, H.F. & Muriuki, A.W.

Abstract

Maize (Zea mays L.) and bean (Phaseolus vulgaris L.) are commonly grown in association in eastern and southern Africa. Results from 64 fertilizer response trials conducted in Kenya were used to study the relationship between maize monoculture response to fertilizer nitrogen and phosphorus and the intercrop response. The intercrop was more productive that the monoculture with no fertilizer applied, but overall responses of systems to applied nutrients did not differ. Maize, both in monoculture and intercropped, responded more frequently to applied N than did the intercropped bean. Frequency of response to applied P was similar for both crops and both production systems. The basis was established to estimate maize-bean intercrop fertilizer response using response equations for maize monoculture.

Résumé

En Afrique de l'est et australe, le mais (Zea mays L.) et le haricot (Phaseolus vulgaris L.) sont habituellement cultives en association. Les resultats de 64 essais de reponse aux fertilisants conduits au Kenya etaient utilises pour etudier le rapport entre les reponses de l'azote et du phosphore au mais en monoculture et en culture mixte. La culture mixte etait plus productive que la monoculture qui n'a pas renu de fertilisants. Toutes les reponses des systemes qui ont renu les fertilisants n'etaient pas differentes. Le mais, a la lois en monoculture et en association, repondait plus a l'application d'azote que le haricot en association. La frequence de reponses a l'application du phosphore etait similaire pour toutes les 2 cultures et dans tous les 2 systemes de production. La base etait ainsi etablie pour estimer la reponse de fertilisants a la culture associee de mais - haricot en utilisant les equations de reponse pour le mais en monoculture.
