Response of tomato to coffee pulp and phosphate rock composts applied to a phosphorus deficient Ultisol

A glasshouse experiment was conducted using tomato (Lycopersicon esculentum M.) var. Carl J to investigate the effect of composting coffee pulp with Minjingu phosphate rock (MPR) on phosphorus availability, plant growth and yield response on a phosphorus deficient Ultisol . Coffee pulp compost, MPR and coffee pulp composted with MPR were applied at equivalent rates of 0, 40, 80, 100, 120, 140, 160 and 200 kg P ha-1. Coffee pulp composted with MPR significantly (p=0.05) improved tomato response relative to direct applied MPR and coffee pulp composted alone.
Une expérience de serre a été entreprise en utilisant une variété de tomate Carl J (Lycopersicon esculentum M.) pour étudier l’effet de composter la pulpe de café avec le phosphate naturel de Minjingu (MPR) sur la disponibilité de phosphore, croissance de plantes et réponse de rendement sur un Ultisol déficient de phosphore. Le compost de pulpe de café, les MPR et la pulpe de café compostée avec MPR ont été appliqués à des taux équivalents de 0, 40, 80, 100, 120, 140, 160 et 200 kg P ha-1. La pulpe de café compostée avec MPR a amélioré de manière significative (p=0.05) la réponse de tomate relative au MPR appliqué directement et la pulpe de café compostée seule.

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"
