Abstract
Abstract In a 4-year study of tomato cultivar (VF-145), using densities from 316,160 to 3,877,900 plants/ha, growth was most rapid below 963,300 plants. The highest yield of marketable fruits, 104.9 millier/ha, was attained with 617,500 plants/ha. Soluble solids in the fruits declined, and plant sugar content increased, at densities above 963,300 plants/ha, concurrent with a reduction in leaf area per plant. Differences in plant density had no significant effect on nutrient content of the plants. Potassium deficiency symptoms were evident at all densities shortly after fruit-set. Total K absorbed by plants increased from 439 kg/ha with 316,160 plants to 1997 kg/ha with 3,877,900 plants.
