Abstract:

Three potassium fertigation rates (T1 = 100%, T2 = 60%, T3 = 30%) via trickle irrigation, fertilization rates (T4 = 100%, S1 = 100%, S2 = 50%, S3 = 0.0) and nonfertilization (T5 = 0.0) on commercial yield of sweet peppers under drip irrigation were evaluated in a Vertisol soil at Fortuna Agricultural Experiment Substation located in the semiarid south coast of Puerto Rico. Fertigation and fertilization increased commercial yield significantly (P = 0.05) compared to non-fertilized plots. Mean commercial yield was not significantly different (P = 0.05) fertigation and banded application at the highest rates (T1 and T4 plots).
