These higher yields probably result from a <br />combination of factors, the most important of which is management. <br />Other factors affecting yields include soil types, location, weather, <br />and the amount of fertilizer and spray materials used. Yields for the <br />various management levels are shown in Table 5. <br /> <br />Table 5.
