Research results from the neotropics showed a high positive correlation between plant population densities and yields of marketable berries in hot pepper (Capsicum chinense Jacq.). Densities were compared on a Piarco Series soil (Ultisols of the Aquoxic Tropudults sub-group) during 2011 in central Trinidad on cv. Moruga Red to determine the density that will produce the highest yields of berries, mean berry weights and mean plant developmental traits. The 16 different densities ranged from 60 x 30 cm to 150 x 120 cm.
