African Crop Science Journal Vol.5. No.2, pp. 257-262 1997 On-farm forage/food crops sequential system and its residual effects on subsequent wheat cultivation ABATE TEDLA, N.Z. LUPWAYI and HAILU REGASSA Code Number: CS96064 Sizes of Files: Text: 15.1K Graphics: Tables 12.3K (gif) - 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. Key Words: Chickpea, Ethiopian highlands, oats, on-farm, sequential cropping, vertisols, vetch RESUME 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 jacherecultures 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.
