The farm-economic results of the increase of area and yield of Brussels sprouts grown on a share-cropping basis. Brussels sprouts are grown mainly on a share-cropping basis in the Netherlands. In the last years the costs for the share cropper have risen more than those for the farmer. To achieve an insight into the cost structure the production costs have been calculated. With a yield of 9,250 kg and an area under Brussels sprouts of 1 ha per share cropper the production costs in North Groningen are Dfl. 3,850 per ha. If picking is started a week earlier, the yield is 7 percent higher. Picking is often started too late to obtain the highest possible yield and returns. The average course of prices in the past ten years showed that an earlier start of picking did not reduce the average prices. Yield increase causes a degressive reduction in the number of work hours applied for picking and sorting per kg of product. The resulting decrease in cost price varies from Dfl. 0.31 to Dfl. 0.61 per kg for yield ranging from 5 to 13 tons per ha. Yield increase too hardly reduces the average prices. By increasing the area per share-cropper the labour requirement for picking is reduced linearly. This causes a reduction in the costs per kg of product from Dfl. 0.42 to Dfl. 0.38 per kg in plots varying from 0.5 to 2 ha with a yield of 9,250 kg/ha ; the returns per kg are not reduced. The costs of the share cropper show a greater fall than those of the farmer, the percentage being 28 and 6 respectively. If in North Groningen, Brussels sprouts are picked earlier and the area per share cropper is increased, the costs are reduced, but not the proceeds.
