Yields of Tomatoes As Influenced By Application of Filter-Press Cake and Starter Solutions

Abstract

An experiment using the Manalucie variety of tomato was established on a Vega Alta sandy clay soil at Río Piedras, P.R., with various combinations of filter-press cake, and starter solutions such as Folo-food, Growgreen, and 9-10-5, in addition to the regular commonly used fertilizer, 9-10-5. Filter-press cake increased the marketable yield by 6.76 tons. When filter-press cake was not applied the use of starter solutions failed to increase yields. A starter solution made from a 9-10-5 fertilizer was just as effective as the commercial starter solutions. The use of filter-press cake and/or starter solutions is recommended for tomato production in Puerto Rico.
