The conventional fertilization of field grown green peppers consists of a basal application and several topdressing. With a single basal application of polyolefin coated fertilizer (POCF), topdressing can be eliminated, thus labor costs can be reduced. In this study, a single basal application of POCF was compared to the split application of readily available fertilizer (RAF) in 1996 and 1997. In 1996, plants given POCF were taller and gave better early and total yield than those given RAF treatment. In 1997, the yield was the same for both RAF and POCF, however in the early growth stages, POCF gave better yield than did RAF. fruits given POCF had higher average vitamin C content than did those given RAF. The nitrogen, phosphorus and potassium concentrations of fruit from the POCF plants were also higher in this year. From the above, it can be concluded that a single basal application of POCF fertilizer is recommended, as a labor and energy saving fertilization method for field gr
