Abstract
ABSTRACT Fertilizer amount affects pepper yields (Capsicum annuum var. annuum L.), and can affect fruit color. An N-P-K fertilizer was applied at the rate recommended for this location, based on soil test results, and 1.5-times that rate. Green and red fruit yields of five bell and five non-bell pepper cultivars, as affected by fertilizer rate, were determined. Yields of all cultivars were higher in 1996 than in 1998 when day and night temperatures were much above normal. In 1996, increasing fertilizer rate caused decreases in green and total yield of bell peppers, but had no effect on red fruit yield. In 1998, additional fertilizer increased total yield of ‘Melody’, and decreased that of ‘Red Beauty’. In both years, increasing fertilizer rate increased green and total, but not red, fruit yield of some, or all, non-bell peppers tested. Additional fertilizer above the standard rate did not improve red fruit yield at this location.
