Сортова мінливість маточних коренеплодів буряка столового сорту Бордо харківський

Abstract

The reaction of the varieties of beet Bordo Kharkov on meteorological conditions in the years 2000-2011 is defined, the standards for the sample years  in precipitation and temperature, relative humidity, by using the coefficient of elasticity (E) are established, the effect of meteorological conditions on crop yields uterine roots for years of researches are determined. It is established that the formation of high-quality commercial products of uterine beet root  is  in direct proportion to the amount of precipitation (r = 0,69), the amount of tem- perature (r = 0,51) and relative humidity. It was found that  with  increasing relative humidity of 1% the yield of uterine beet root is increased by 580 kg, under conditions of increasing the amount of effective temperatures for 1 0C  yields are reduced by 17 kg, the increase in total rainfall of 1 mm enlarges the yields of uterine roots to 54 kg
