Factors Affecting the Growth and Distribution of Winter Wheat Roots Under Uk Field Conditions

AbstractLaboratory and field experiments indicate that the female spruce budworm (Choristoneura fumiferana (Clem.)) pupal stadium requires approximately 122C degree-days above a threshold of 7.2 °C (45°F), the male 124. Emergence time on any given day depends on temperature but is independent of photoperiod. Under field conditions male and female budworm mate only once per 24-h period. In the laboratory under continuous illumination females mate repeatedly and males readily mate a second time within a few hours, but the duration of the second copulation is abnormally long. The probability of multiple matings under field conditions is reduced by the restricted period of sexual activity coupled with the duration of copulation and the lower competitiveness of mated insects. Antennae are essential to the male for successful copulation.

Experimental Plots

To carry out effective plant protection measures, it is necessary to take into account all the factors affecting the quality of the crop. The aim of our research was to study the degree of development of leaf diseases of winter wheat and the rate of infestation of crops, depending on the tillage method. The studies were carried out in 2019-2020 at the experimental plots of “Kuban educational farm” in Krasnodar. For the research, four experimental plots with Steppe variety of soft winter wheat were created, where various soil cultivation systems were applied: 1 - No-Till (zero technology), 2 - moldboard-free technology, 3 - recommended, 4 - moldboard technology. The article presents data on the degree of development of diseases and the degree of infestation of winter wheat plants in the crops of test plots with various tillage systems. It was found that the most preferable is the use of the recommended type of treatment, since with it the least number of diseases develops and the degree of development of pathogens is reduced by 2-3 times in comparison with other options. The influence of the tillage method on the number and composition of phytopathogen spores was revealed.
