Jalapeño pepper can provide important antioxidants for the human diet. In Mexico, there is a tendency to improve its yield and quality. Recently, the use of bioregulators and oxidation promoters in tomato, broccoli and cabbage has been shown to improve harvest yield and quality. The objective of this study was to evaluate the effect of prohexadione calcium (P-Ca), benzoic acid (BA) and salicylic acid (SA) on yield and the levels of capsaicin and vitamin C in jalapeño pepper var. M. The study was conducted under greenhouse and laboratory conditions at the Universidad Autonoma Agraria Antonio Narro in 2007. The treatments were, P-Ca, BA, SA, and water (control) applied in the seed, seedling and plant stages. The variables were concentrations of capsaicin and vitamin C in ripe fruits and total yield per plant. The content of capsaicin and yield were statistically higher in the three stages with applications of P-Ca (100, 150 and 200 mg·liter¹) individually or in combination with BA and SA (1x10^-6 M). The level of vitamin C increased when P-Ca at 100 mg·liter¹ was applied to the seed.
