The effectiveness of basin tillage on maize production in the semi-arid Dayataya ward of southern Zimbabwe

Abstract

This study examines the effectiveness of basin tillage in maize production in Dayataya ward located in the semi-arid district of Zvishavane ward in southern Zimbabwe. The study was based on questionnaire surveys and interviews with key informants, field observations, and secondary data sources. The major findings of the research were that even though many small scale farmers have adopted basin farming in the Dayataya ward, most of them have not fully implemented the requirements of basin tillage. Not all farmers have incorporated mulching as a special requirement in improving soil moisture in basin tillage. Basin spacing and plant population fall far below the regional standard. Plot fencing is also an area of concern since farmers need to protect their mulch from livestock during the winter season. Yield of maize per hectare has shown some improvement. The research recommends farmers to take a holistic approach towards basin farming. A full basin tillage package that comprises proper basin spacing, plant per hectare, and other on-land rain water harvesting techniques, such as deepening of contours and placing infiltration at strategic positions, may also help farmers to improve soil moisture.
