Influence of weather conditions on passage and duration of phenological phases of growth and development for oilseed crops
Journal Title: «Таврійський науковий вісник» - Year 2018, Vol 99, Issue
Abstract
The article shows the results of the analysis of agrometeorological conditions for the growth and development of sunflower, oilseed flax and safflower in the South Steppe zone of Ukraine. The regularities of influence of growing conditions hydrothermal factors on the duration of interphase periods of oilseed crops are revealed. It was determined that at the beginning of vegetation period of the studied crops rainfall amount significantly affects the onset rate of the developmental phases (the correlation coefficients are 0.74-0.93). During the formation of generative organs, the complex hydrothermal factor HTC (hydrothermal coefficient) shows the biggest influence, which is confirmed by the correlation coefficients in the range of 0.79-0.95.
