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.
