Millet was grown with and without added phosphorus at one temperature and moisture level on samples of two soils which had been incubated for 74 days at 23°, 2.7°, and −20.5° C. and at moistures of 40, 60 to 70 and 100 percent of field capacity. The higher the soil temperature prior to cropping, the greater was the yield of dry matter and phosphorus uptake. Soil moisture contents prior to cropping did not affect yield and phosphorus uptake. Millet was also grown at three soil moisture levels and at two soil temperatures. The effect depended on the accompanying temperature. The soil moisture level did not affect the yield and phosphorus uptake at a soil temperature of 16° C. but did affect it at a soil temperature of 21° to 33° C. during the cropping period. Response to phosphate in field trials with wheat was related to both temperature and rainfall during the growing season.
