Upscaling the use of efficient and affordable soil fertility replenishment practices for small holder farmers of western Kenya

The study assessed the agronomic effectiveness of fertilizer use recommendations in western Kenya on maize yields. The treatments included: FURP – 75kg N/ha CAN and 26kgP/ha DAP; 2) FURP – 75kg N/ha CAN and 26kgP/ha DAP plus lime (2t/ha); 3) FURP – 75kg N/ha CAN and 26kgP/ha Minjingu phosphate rock; and 4) Rutuba bio Agricultural organic manure at 125kg/ha and DAP at 13 kg P /ha. Inclusion of agricultural lime and manure in combination with mineral fertilizers significantly increased yields in this rather acidic environment.
L’étude a évalué l’efficacité agronomique de l’utilisation d’engrais, sur recommandations, dans l’ouest du Kenya sur les rendements de maïs. Les traitements comprenaient: FURP - 75 kg N / ha CAN et 26kgP/ha DAP; 2) FURP - 75 kg N / ha CAN et 26kgP/ha DAP addition de chaux (2t/ha); 3) FURP 75 kg N / ha CAN et 26kgP / ha Minjingu phosphate et 4) Rutuba, engrais organiques bio agricole de 125kg/ha et DAP à 13 kg P / ha. L’inclusion de la chaux agricole et du fumier en combinaison avec des engrais minéraux a augmenté les rendements de manière significative dans cet environnement plutôt acide.

"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 stakeholers 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 soil science and water management".
