WEATHER-BASED SPRING WHEAT YIELDING FORECASTING

Bo┐ena Michalska, Agnieszka Witos

 

ABSTRACT



The research draws on 1970-1998 decade rainfall, maximum, minimum and average air temperature, relative air humidity recorded at 1 p.m. and insolation; all of them reported by 6 Meteorological Office (IMGW) stations and by one agricultural meteorological station and on spring wheat yielding reports provided by Provincial Statistical Office (WUS). Multiple regression was used to define the relationship between yield and weather components over respective periods. The regression equations developed for the Zachodnie Pomorze Province can be applied to forecast spring wheat yielding. Preliminary forecasts are available late in May, whereas precise forecasts late in June and July.

Key words: spring wheat, weather components, yielding forecasts.
