Abstract

An experiment to determine the effect of fertilizer N and P on the growth and yield of sweet pepper grown on a Coto soil, a Tropeptic Haplorthox, was conducted at lsabela in northwestern Puerto Rico. The experiment consisted of 12 treatments, with five replications distributed in a complete randomized block design. Treatments included N fertilizer levels of 0, 75, 150, 225, 300 and 375 kg/ha; and P levels of 0, 33, 65, 98, 131 and 164 kg/ha. All plots received 150 kg/ha of K, except for the non-fertilized control. Pepper responded significantly to the application of 300 and 375 kg/ha of N when compared to 0 N application. However, there were no significant differences among N levels. There was no response to the application of P. Treatments had no significant effect on the time interval between transplanting and flowering. The N levels in the leaf were correlated with yield, whereas P levels were not.
