Evaluation of new cultivars of mango (Mangifera indica L.) in Ghana. 1. Growth performance

Abstract

Data for girth and tree size are presented for 14 new mango cultivars planted at Ejura in the forest savanna u-ansitional zone of Ghana. Girth increases in all cultivars were approximately linear from 1969 tg 1971. Trunk increase was fastest in Sunset followed by Palmer and Jacquelin in that order. Ruby exhibited the slowest trunk growth over the period. Corresponding tree size development was most pronounced in the three cultivars with fastest trunk growth. Ruby size development was slowest among the cultivars. Edaphic and weather conditions at Ejura favouring general growth of mango are outlined.
