Wpływ elementów meteorologicznych na rozwój i plonowanie żyta ozimego i pszenicy ozimej w rejonie środkowowschodniej Polski

The aim of this work was the proof of hwestigation of influence such meteorological elements as temperature, precipitation and sunshine on the developing and yelding many plants cultivated in field. There were winter rye and winter wheat. Agrotechnical and meteorological data from six Research Station from Cultivars Estimation were taken. The data come from experiments which were carry out in 1985-1995. In this work it was tried to finde the regression equations, which in the best way we can estimated the correlation between developing of some plants as well as the yielding level and meteorological conditions. Using the multiple linear regression the equations for this dependence has been built. There was found a significant dependence of the developing and yielding of cultivated plants on common interaction such meteorological elements as temperature and precipitation. From many investigated elements we can state that the temperature is the most important factor, which was effected on the plants developing specialy on the interphases duration.
