The effect of super phosphate and planting density on mini-tuber production from true potato seed

Abstract: 
Improving tuber seed quality and availability is institutionally complex in the tropics and sub-tropics. The main objective of this work was to evaluate the effect of superphosphate and plant density on mini-tuber production from true potato seed. The enhancement of all growth variables was due to P availability in the soil allowing plants to develop without restrictions as rates increased. Days to maturity, shoot P, tuber dry matter, shoot dry matter and specific gravity showed significant responses to superphosphate. Phosphorus showed significant yield increases with increase in application rates. Yield also increased significantly by weight with decreased planting spacings adopted.
Améliorer la qualité et la disponibilité des semences de tubercules est institutionnellement complexe dans les régions tropicales et sub-tropicales. L’objectif principal de ce travail était d’évaluer l’effet de superphosphate et de la densité des plantes sur la production de mini-tubercules à partir de semences de pomme de terre. La mise en valeur de toutes les variables de croissance était attribuable à la disponibilité du phosphore dans le sol permettant aux plantes de se développer sans restriction comme les taux augmentaient. Les jours de maturité, de P de pousse, de la matière sèche des tubercules, de matière sèche de pousse et de la gravité spécifique ont montré des réponses significatives au superphosphate. Le phosphore a montré des augmentations de rendement importantes avec l’augmentation des taux d’application. Le rendement aussi a augmenté considérablement en poids par des espacements décroissants de plantes adoptés.

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"
