AbstractA yield regression model was developed for soybeans (Glycine max (L.) Merr.) of DIRA-Ribeirão Preto, using total evaporation in December, relative humidity of January and a surrogate technology trend as independent variables. Eighty percent yield variation of soybeans from 1956 to 1978 was explained by the regression equation, which provides yield information in the beginning of February - two months after planting. The forecasted yield for crop year 1978-1979 is 1576.22 kg/ha if the past weather patterns and technology improvements continue. The results show that the standard monthly meteorological elements-relative humidity and total evaporation are better yield determinants for soybeans and corn than total precipitation and mean temperature which were used in the Thompson 's models.
