Yield and Nutrient Composition of Tomatoes in Relation to Soil Temperature, Moisture, and Phosphorus Levels¹

ABSTRACT

Tomato plant growth was determined for 4 soil temperatures in combination with 2 soil moisture conditions and 3 phosphorus levels. There was a curvilinear relationship between yield and temperature. The highest yields were at 68°F., low soil suction, and high phosphorus. Yields increased with decreasing soil suction and with increasing phosphorus. Chemical leaf analysis, with exception of Mg, showed Ca, K, P, N, Cu, Fe, Mn, and Zn to vary significantly with temperature changes. Ca, Mg, K, N, Mn, and Zn were increased with decreasing soil moisture. Ca, Mg, K, P, N, and Mn tended to decrease with higher rates of phosphorus.
