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