The experiment studied the effect of various mulching terms of ‘Foxtrot’ tulips with wheat straw in combination with spraying of plantations with herbicides using various doses and different amounts of working liquid. The mulch was laid out just after planting and after the soil had frozen. The experiment included combinations, in which the mulch was left until the end of the growing season or removed...
The objective of the study was to determine the relationships between the yields of basic crop plants and the changes in some meteorological elements. The report, which covers the results of five years of experiments, presents the coefficients of correlation and regression, as well as diagrams of the yield versus a given meteorological element. It was found that the mean yearly air temperature had...
During the period of 1981-1985 measurements of vertical movements of soil were carried out at the Agrometeorological Observatory at Felin, Lublin. During the cool half-year from November through April, the authors analyzed maximum diurnal movements in a decade, decade amplitudes, and the number of days with vertical movements in a decade. Also assessed was the extent of wintering of rye and wheat,...
