Bell pepper plant losses at transplanting may reduce yields. Growers often use subjective visual observations to determine reductions in plant stand but do not have a basis for determining if missing plants should be replaced or how soon. This study was initiated to determine effects of stand deficiencies and replanting on yield and fruit size of pepper during the spring 1992 and 1993.

`Jupiter' bell pepper plants were transplanted to the field in late March and spaced 30 cm apart on 1.2-m beds mulched with black plastic. Treatments included a control [0% stand deficient (SD)] and 10, 20, or 30% SD plots that were established at transplanting. Each SD treatment was replanted to a 100% stand two or three weeks after initial transplanting or was not replanted.

Yield of extra-large and marketable fruit was not affected by stand deficiencies or replanting in either year. Stand deficiencies up to 30% did not result in reductions in total/early yield or fruit size.
