<p>Nigeria is losing out on a significant $40 million per year due to rejection of cashew nut crops, according to the president of the National Cashew Association of Nigeria, Tola Faseru.The issue is that farmers, keen to take advantage of weight based sales are not processing and drying their nuts themselves. Which means there is a higher cost in supplying the nuts as they later have to be dried, sorted and graded.This has led to discounts of 20-30% being offered for the produce, causing the exporters to receive lower prices from buyers in India and Vietnam - the world's largest markets for cashews.Mr Faseru is asking farmers not to sell directly to buyers, but instead to sell their produce through the association and follow guidelines for drying out and thus, increase quality.<br></p>
