Asparagus (Asparagus officinalis L.) may be cultivated either for white or for green spears, the latter method started to prevail in the world in the last years. The aim of the study was a comparison of yielding of white and green asparagus cv. ‘Ravel’ in the open field and in the PE tunnel. The weight, number and diameter of spears in the total, marketable and non-marketable yields in the first and second harvest year were assessed. Total and marketable yield of white asparagus was higher than that of green one, but the latter formed significantly more spears in the total and nonmarketable yield. The yield and number of spears obtained in the tunnel was significantly higher than with no cover. Marketable spears constituted on average 77.8% of yield weight and 63.0% of the total number of spears and the values for both cultivation methods were similar. Mean weight and diameter of white spears were higher than those of the green ones.
