ON THE PLOT How to grow vegetables for profit S outh Africa's food and agricultural policy historically placed national self-sufficiency as a major objective. Until recently this goal was largely met, as a surplus was produced in most major agricultural commodities. From page 32 lettuce may deter insects. Oregano planted with broccoli may repel cabbage flies. A further protection for your plants is the use of mulch. Mulch is a layer of materials used to cover soil so that you reduce evaporation, keep soil moist, moderate soil temperature (warm in winter, cool in summer), reduce weeds and soil erosion. Mulch can help to fertilise your soil. Organic mulch can be made Farmers and others in the agricultural value chain are recognised for their ability to respond and survive, while managing risk responsibly. However, climate change presents a new and very significant threat to agricultural systems. It has become C increasingly difficult for the agricultural sector in South Africa to provide sufficient quantities of food at affordable prices. This summer's drought and the effect of El Nino have exacerbated the situation. So should smallholders then WINTER VEG from bark, dead leaves, straw, compost, nut shells, stones, bark chips, pebbles, etc. Simply spreadBa thin layer of mulch over your vegetable patch, taking care to avoid A plants and their covering stems, to gain the benefits. Paying attention to watering is also important to the success of your winter kitchen garden. Gauteng winters are cruelly dry, and because things tend to quieten down in the garden many neglect to water sufficiently in winter. By the same token, vegetables by their very nature (think of the moisture found in a tomato) generally require much more water than flowers or shrubs, so be sure to water at least twice a week, or more depending, on the vegetable and your soil. Ensure deep watering - the water should reach 30cm into the soil. Water in the warmth of the morning. Where there is risk of frost do not water in the afternoon or evening. 33 www.sasmallholder.co.za be thinking about growing vegetables commercially, as a means of making an income and to meet the needs of the community? Before setting up a production unit, we need to consider a number of factors. We should understand the risks and know our own strengths and how to overcome our weaknesses. When does production become profitable? According to the Agricultural Research Council (ARC), if, for example, onions are grown on 1ha of land, a yield of 4 000 bags of 10kg each is possible. At R22 per 10 kg bag (R2,20/kg), this can provide a gross income of R88 000. Say your input costs are R1/kg, your profit is R1,20/kg. But if the smallholder is only paid R16 a bag, his profit is Continued on page 35
