- The relationships between the yield and meteorological elements have been stated by the use of multiple regression model selection. Winter wheat yield was taken as dependent variable and three groups of meteorological elements were taken as independent variables. Simple meteorological elements belong to the fi rst group of independent variables; their nonlinear combinations (square, square root) belong to the second group. The third group has included complex elements they are functions basing on the relationships between plant growing and environmental conditions among others meteorological conditions. Stations Sulejów has been the source of longterm meteorological, phonological and winter wheat yield data. The station is situated in central part of Poland and winter wheat is grown on medium type of soil. The regression equations including both simple meteorological elements, their nonlinear combinations and complex variables achieves the best statistical characteristics than the equations including simple elements only.
