Comparative effect of farmyard manure, cowpea residues and NPK Fertilizer on maize grain yield in Morogoro

Optimal combinations of organic and inorganic fertilizers can give rise to increased maize yields in nutrient depleted soils. In this study, we assessed the effectiveness of cowpea residues and combinations of inorganic fertilizers on maize yield. Integration of 40 kg/ha N, 10 kg/ha P and 50 kg/ha K and organic fertilizers improved maize yields significantly. In areas where cowpea is produced in reasonable quantities, its residues can be used to improved maize yields.
Les combinaisons optimales d’engrais organiques et inorganiques peuvent donner lieu à une augmentation des rendements du maïs en éléments nutritifs des sols appauvris. Dans cette étude, nous avons évalué l’efficacité des résidus de niébé et de combinaisons d’engrais minéraux sur le rendement du maïs. L’intégration de 40 kg / ha N, 10 kg / ha de P et 50 kg / ha K et les engrais organiques améliorent les rendements du maïs de façon significative. Dans les régions où le niébé est produit en quantités raisonnables, les résidus peuvent être utilisés pour améliorer les rendements du mais.

About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Natural Resource Management"
