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 Integrated Crop Management
Effect of Integrated Water and Nutrient Management Technologies on Soil Profile Moisture Content and Grain Water Productivity in Zimbabwe
Abstract:
This paper reports results of an on-farm experiment done to
quantify soil moisture storage, water and water productivity of
maize and soybean as affected by tillage and fertility
management systems during 2009/2010 and 2010/2011 cropping
seasons. The aim of the study was to investigate the effect of
cattle manure and inorganic fertiliser (compound D) under tied
ridging, conservation farming basins, conventional mould board
plough, rip and potholing on soil profile moisture storage and
water grain productivity. The results showed that there is no
interaction between tillage system and fertility management
options on determining water productivity and soil profile
moisture storage. However tillage systems and fertility
management options independently had an impact on water
productivity while soil profile moisture storage was affected by
tillage systems alone.
Cet article présente les résultats d’une expérience menée dans
une exploitation agricole pour quantifier l’accumulation en
l’humidité dans les sols, l’eau et la productivité de l’eau du
maïs et du soja telles que affectées par le labour du sol et les
systèmes de gestion de la fertilité durant les saisons culturales
2009/2010 et 2010/2011. Le but de cette étude était de
rechercher l’effet du fumier des bovins et des engrais
inorganiques (composé D) sous le billonnage conditionnel, les
bassins de l’agriculture de conservation, la charrue
conventionnelle de l’ensemble de l’humus, la déchirure et la
spéléologie sur l’accumulation en humidité du profil des sols et
la productivité de l’eau dans les céréales. Les résultats ont
montré qu’il n’y a pas d’interaction entre le système de labouret les options de gestion de la fertilité sur la détermination de la
productivité de l’eau et l’accumulation en humidité du profil des
sols. Toutefois, les systèmes de labour et les options de gestion
de la fertilité avaient indépendamment un impact sur la
productivité de l’eau tandis que l’accumulation en humidité du
profil des sols a été affectée seulement par les systèmes de
labour.
