Fertilizer trials were made with tomatoes, Rutgers variety, and cucumbers, P.R. 39 and Ashley varieties, in the Southwestern section of Puerto Rico with the following results: 1. For tomatoes at Jayuya, on a Jayuya silty clay loam, highest yields were obtained with 50 pounds of nitrogen and 100 pounds each of P2O5 and K2O per acre. Liming at 1,000 pounds per acre did not increase yields significantly. 2. The more fertile Santa Isabel clay of the Lajas Valley failed to respond significantly to variations in nitrogen, phosphate, or potash for tomatoes or cucumbers. 3. Cucumbers grown on a Paso Seco silty clay loam at the Fortuna Substation showed significant yield responses to 100 pounds of nitrogen and 50 pounds of P2O5 per acre.En pruebas d...
