Résumé

Un essai en milieu paysan a ete realise durant deux saisons sur des vertisols de 
hautes terres d'Ethiopie pour evaluer un systeme sequentiel de fourrage/cultures
vivrieres comme alternative au systeme traditionel de jachere\cultures vivrieres. L'
efficacite de l'azote residuel resultant de la culture sequentielle et de systeme de
jachere comme supplement d'azote dans une culture de ble etait aussi analysee. Le
pois chiche cultive en humidite residuelle apres une culture mixte d'avoine/vesce ou
jachere donnait le meme rendement. Dans la deuxieme annee, les rendements de
grains de ble et de paille augmentaient significativement apres un traitement de 60 kg
d' azote tandis que le rendement de paille augmentait apres un traitement de 30 kg
d'azote en comparaison de 0 kg.

Abstract

An on-farm trial was conducted over two seasons on Vertisols in the Ethiopian
highlands to evaluate a sequential forage/food crop system as an alternative to the
traditional fallow/food crop system. The efficiency of residual nitrogen from
sequential cropping and fallow systems as a supplement to applied nitrogen in a
wheat crop was also tested.  Chickpea grown on residual moisture preceded by either
oats/vetch mixture or a fallow had similar yields.  In the second year, both wheat
grain and straw yields were significantly increased at the 60 kg nitrogen level
treatment while the straw yield was also significantly increased at the 30 kg nitrogen
level compared to 0 nitrogen level.
