Conteúdo: 	Bell pepers (Capsicum annuum L. cv. Early Calwonder) were plug-mix seeded at 13-, 25-, 38-, and 51-cm within-row spacings in two rows on raised beds and thinned to one, two, or three plants per hill upon emergence. The experiments were conducted on commercial pepper fields located in southern Florida during the Winter l983 and Spring l984 seasons. Populations ranged 21,527 plants/ha. Plant growth characteristics were measured at anthesis and just before the final harvest in each experiment. Root and shoot weights, shoot: rrot ratios, and stem diameters generally decreased and plant heights generally  increased in response to higher plant populations. The lower shoot: root ratios at higher plant populations indicated that plants were producing more rootmass in proportion to shoot mass than plants as lower populations. Number of primary and secondary branches per plant in the two experiments averaged 2.7 and 5.3, respectively, and were generally not  influenced by plant populations. Marketable fruit yields/ha increased linearly in response to higher plant populations. Marketable fruit number and weight per plant decreased with higher plant populations, whereas fruit size (g/fruit) was unaffected.  This observation suggested that the higher marketable yield/ha at higher plant populations were attributed to more plants with a lower number of similarly sized fruits per plant. The 25-cm within-row spacing with two plants per hill resulted in 81,l09 plants/ha, the optimum marketable pepper fruit yield.
