Research was undertaken in the summer and fall of 1988 to determine the effect of phosphorus placed below, below and to the side, banded and incorporated, and broadcast on the yield and quality of tomatoes.
The results of the field study were not statistically significant due to high levels of available soil phosphorus. However, there were trends toward higher total yields, higher yield of number one grade tomatoes, and higher tissue phosphorus levels when phosphorus was placed in a concentrated zone or band as contrasted with the more popular broadcast method.
The effect of phosphorus placement in the greenhouse was studied using two different soils, a high available phosphorus soil and a low available phosphorus soil. Again, phosphorus placed in a concentrated zone produced plants with higher tissue phosphorus levels, regardless of the soil the plants were grown on.
