Potassium has a great influence on fruit quality and is effective in hardening growth at high rates. Potassium levels are particularly important at planting time for growth control and later for the prevention of ripening disorders. The ratio between potassium and nitrogen is also important in growth control-the higher the ratio the slower the growth. Problems with fruit quality, such as blotchy ripening, boxy fruit, and even to some extent, greenback, are associated with low levels of potassium and in most cases can be counteracted with high-potassium feeds. The proper management of irrigaton and a stable salt content of the soil solution are also factors in avoiding blotchy ripening.
