CORRELATION RELATIONSHIP PRECIPITATION DURING THE GROWING SEASON AND YIELD OF POTATO TUBERS IN VARIETIES OF DIFFERENT MATURITY GROUPS
Abstract
The correlation dependence of rainfall was mean and high positive and depended on the maturity group of potato varieties. In early and mid-early varieties of potato, a correlation coefficient was positive (0.386...0.419), in mid-ripening and mid-late varieties it was high positive (0.664...0.697). The optimal amount of precipitation in May and June for the early and mid-early potato varieties was from 200 to 250 mm, which provided an average yield of 33.9 and 34.8 t/ha, and for the mid-ripening and mid-late varieties those indices were as follows: from 200 to 300 mm – 36.3 and 37.4 t/ha. Under the conditions of both higher and lower precipitation, potato yield decrease was marked.
