Abstract

Field studies were conducted in 1991 and 1992 to evaluate the effect of in-row spacing on machine-harvested jalapeno pepper (Capsicum annuum L.) yield and plant characteristics. In 1991, 'TAM Mild Jalapeno-1' (TAMJ1) and 'Jalapeno-M' (JM) were planted at 4-, 8-, 12-, and 16-inch (10-, 20-, 30-, 40-cm) in-row spacings and, in 1992, TAMJ1 was planted at 3-, 6-, 9-, and 12-inch (7.5-, 15-, 22.5-, 30-cm) spacings. Total marketable yield increased linearly for JM (in 1991), while the yield response was quadratic for TAMJ1 in 1992 with narrower in row spacing. Total marketable yield for JM (1991) and TAMJ1 (1992) was highest for the narrowest spacing, 4 and 3 inches, respectively. Red fruit yield of both cultivars in 1991 increased linearly with narrower spacing. In 1992 there were no differences in red fruit yield among in-row spacings. Plants lodged more at wider spacings. In-row spacings as narrow as 4 inches may increase marketable yield of machine-harvested jalapeno pepper.
