Shupikai Ndigwirei, a Zimbabwean agriculture student explains cultural and mechanical methods of weed control for maize crops.
Cue: For maize farmers, controlling weeds is one of the most important tasks in achieving a good harvest. Maize plants emerge from the soil more slowly than weeds, and do not cover the soil until they are two or three months old. This means that while the maize plants are young, there is plenty of opportunity for weeds to grow around them. And if farmers use large amounts of fertilizer on their maize crop, this can also help the weeds to grow even faster. As a result, weeds can become a serious competitor to the maize plants, taking much needed water and nutrients, unless careful weed control is practised. Controlling weeds usually involves either killing the weeds that emerge, or using cropping practices that prevent weeds growing in the first place. In our next report, an agriculture student from Zimbabwe called Shupikai Ndigwirei, explains to Sylvia Jiyane about methods of weed control that may be suitable for small-scale maize farmers who have little capital to invest in chemicals or mechanical weeders.
