Description:

Ridge formation with strip tillage alleviates excess moisture stress for drought-tolerant crops.

Summary / Notes:

The impact of climate change is expected to be more severe in semi-arid and arid ecosystems. Seasonal and high-rainfall floods have recently become a common occurrence in semi-arid sub-Saharan countries in southwestern Africa, where ridging is becoming an important method to alleviate flooding stress in drought-tolerant crops. Theobjective of this study was to propose a feasible tillage method and compare its agronomical effects to those ofconventional tillage practices in northern Namibia in sub-Saharan Africa. Pearl millet and cowpea were grown inthe field using different tillage methods in seasonal wetlands in this area. We investigated crop yield, growthparameters, soil moisture content, and the shape of the ridge. Soil tillage using a newly proposed disc ridger fortwo-wheel tractors resulted in higher yield and growth rate in both crops than using the other tillage methodsi.e.single mouldboard ploughing with animals and/or disc harrowing with four-wheel tractor. Ridge formation withstrip tillage (partial pulverization) using the disc ridger resulted in significantly lower soil moisture content afterirrigation because of the higher aspect ratio of the ridge. It is likely that large undisturbed portion remainedtherewith prevented the ridge from collapsing because of the irrigation water that imitated natural rainfall inthis region. Therefore, ridge formation with strip tillage leads to good drainage, and as a result, proper drying ofsoil prevents flooding stresses thus enhancing early growth and yield of pearl millet and cowpea. Keywords: Ridging, Flood, Sub-Saharan Africa.
