9B. 3 Improving Water Productivity in sub-Saharan Africa
I. Effect of minimum tillage and mulching on maize (Zea mays L.) yield and water content of clayey and sandy
soils. Walter Mupangwa, Steve Twomlow, Sue Walker and Lewis Hove – ICRISAT and University of the Free State.
Rainfed smallholder agriculture in semi-arid areas of southern Africa is subject to numerous constraints. These
include low rainfall with high spatial and temporal variability, and significant loss of soil water through evaporation.
An experiment as been established at Matopos Research Station, Zimbabwe, to determine the effect of mulching and
minimum tillage on maize yield and soil water content. The experiment as been run for two years and set up at two
sites: clay (Matopos Research Station fields) and sand (Lucydale fields) soils, in a 7 x 3 factorial combination of
mulch rates (0, 0.5, 1, 2, 4, 8 and 10 t ha -1 ) and tillage methods (planting basins, ripper tine and conventional
plough). Each treatment was replicated three times at each site in a split plot design. Maize residue was applied as
mulch before tillage operations. Two maize varieties, a hybrid (SC 403) and an open pollinated variety (ZM 421)
