2021-7-31  The average maize yield for the farm is about 5t/ha over a 10-year period, and its average soya bean yield is 2t/ha over a five-year period. “The largest average yield we’ve ever achieved was 7,5t/ha for maize and 3,2t/ha for soya bean. At input costs of around R10 000/ha, the break-even maize yield is roughly 5t/ha.”.

PRODUCTION AND MARKETING OF LUCERNE

2016-4-21  YIELD Yields vary with region, weather, and the crop's stage of maturity when cut. Yields also depend on the plant population, maintenance of the crop and the variety that has been cultivated. Average yield ranges between 15 000 kg to 30 000 kg per hectare. The first cutting gives an average yield of about 1.5-2 tons/ha. and then the yield increases during subsequent
