ABSTRACT In tomato, foliar application of calcium-based nutrient solutions is used to complement soil fertilization. However, knowledge regarding the factors that influence the effectiveness of foliar fertilizer applications remains incomplete. The objective of this study was to evaluate the efficiency foliar fertilization with calcium for improving production and quality of hydroponic Sweet Grape tomatoes. An experiment was conducted in a commercial hydroponic system in a split-plit-plot scheme, with two calcium doses: 1,5 and 3 mmol L-1 of Ca. The solutions were sprayed on the leaves at inte...
