The fertilization regime also affects the concentrations of many secondary metabolites such as capsaicinoids and
phenols [13, 14]. Golcz et al. [15] stated that chili pepper has the greatest requirement for potassium (40%) and nitrogen
(31%) in relation to the total amount of absorbed nutrients. Little is currently known about the effect of soil nutrients on
pepper fruit pungency. Nitrogen availabilitymay have amore direct effect on capsaicin accumulation since the synthesis of
a single capsaicin molecule requires 3mol of nitrogen to be formed [16]. Hence nitrogen availability may affect pepper
pungency through its content in the fruit tissues.On the other hand, potassium may also affect pepper pungency given its
positive effect on fruit development [17]. Previously, some studies have documented N and K effect on hot pepper [18,
19]. However, the results obtained by researchers suggest that K apparently does not notably interfere in capsaicin metabolization.
