There is ample evidence in the literature that environmental conditions occurring during seed filling affects the final composition of soybean seeds. This variability in seed composition is problematic for the industry since the prescribed levels, for example, for protein concentration in the meal, are not always attained. The large variation in these levels in different years and locations commonly renders confusing information. Most literature reports that temperature is one of the major factors influencing protein and oil concentration in the soybean seed. The objective of this study was to determine, under field conditions, the effect of temperature on soybean protein and oil concentrations and to verify whether or not a geographic pattern exists to explain the variations of these levels. Protein and oil concentrations were evaluated in soybean seeds collected during two years in 10 different locations with variations in latitude, altitude and temperature. The largest variations in protein concentration within the same location were best explained by rain distribution during seed filling. Among locations the differences were larger. There was a trend that seed collected at locations with milder average temperatures (21ºC to 23ºC) and higher altitude (>650 m) present higher protein concentration than those collected in locations with higher temperatures (23ºC to 27ºC). When this trend was not observed, the rain distribution during the seed filling and seed yield, again best explained the results. The linear regression for oil and protein was performed aiming at selecting, among nine parameters related to temperature, the most relevant ones in explaining the oil and protein concentrations in the seeds. The regression for protein Concentration (r2 = 0.75; P = 0.0482) showed that mean temperature for January, February and March was the most significant parameter: the lower the mean temperature the higher the protein concentration. On the other hand for oil (r2 = 0.66; P = 0.0448), the temperature for January was the most significant parameter: the higher the temperature the higher the oil concentration. Due to the magnitude of the differences obtained among years and locations, and the importance of small difference in these parameters for the industrial sector, the geographic pattern based only on temperature variations was not sufficient to explain the variations on protein concentration, as expected. This may be the reason for confusing interpretations in relation to variations on oil and protein concentrations. The rain distribution during the seed filling period as well as the nitrogen availability to seeds during the same period, are the key factors to the best understanding of the variations in protein and oil concentrations in soybean seeds.
