The effect of gypsum and NPK fertiliser on groundnut performance in Western Tanzania

This study was carried out to determine the effect of amending soil with gypsum rich material on the performance of groundnuts (Arachis hypogea L.) grown in low fertile sandy textured soil in the miombo woodland ecosystem, western Tanzania. The frequent bush fires, continuous cultivation and use of nitrogenous inorganic fertilisers have resulted in loss of both primary and secondary plant nutrients including Calcium (Ca) and Sulphur (S) which are key mineral requirements for groundnut production. This study was carried out to determine the effect of different application rates of gypsum on performance of groundnut. Results revealed that application of gypsum rich materials and NPK (10:18:24) increased groundnuts kernel yield in western Tanzania. This suggests that the cheap Gypsum materials can be used by resource poor farmers to improve groundnut yields. We recommend that private investors be attracted to process, pack and distribute this cheap fertiliser material to farmers
Cette étude a été réalisée afin de déterminer l’effet de l’amendement des sols avec des matériaux riches en gypse sur la performance des arachides (Arachis hypogea L.) cultivées dans un sol peu fertile à texture sablonneuse dans l’écosystème boisé de miombo, à l’ouest de la Tanzanie. Les feux de brousse fréquents, la culture continue et l’utilisation des engrais minéraux azotés ont abouti à la perte d’éléments nutritifs à la fois primaires et secondaires, y compris le calcium (Ca) et le soufre (S) qui sont des besoins minéraux essentiels pour la production des arachides. Cette étude a été réalisée pour déterminer l’effet des taux d’application différents de gypse sur la performance des arachides. Les résultats ont révélé que l’application des matériaux riches en gypse et de NPK (10:18:24) a augmenté le rendement du grain des arachides à l’ouest de la Tanzanie. Ceci suggère que les matériaux bon marché de gypse peuvent être utilisés par les agriculteurs pauvres en ressources pouraméliorer les rendements des arachides. Nous recommandons que les investisseurs privés soient attirés à traiter, emballer et distribuer cette matière fertilisante bon marché aux agriculteurs.

The 2012 RUFORUM Biennial Conference is the third 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. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under the theme of Integrated Crop Management
