A study was conducted to determine the growth, nutrient uptake and yield performance of tanier cultivars Blanca del País, Kelly and Morada under intensive management. Tanier plants grown under field conditions were harvested for biomass production about every 30 days during the growing season. At each harvest, plants were separated into various plant parts to determine dry matter accumulation, N, P, K, Ca, Mg and in uptake and yield. Maximum uptake of nutrients was 307, 83, 417, 112, 68 and 1.4 kg/ha of N, P, K, Ca, Mg and Zn, respectively, for cultivar Blanca del País. Nutrient uptake by Kelly was considerably less than for Blanca del País and Morada. Overall, there were no significant differences in total dry matter production between cultivars Blanca del País and Morada whereas Kelly accumulated significantly less dry matter. Maximum yields ranged from 11,316 kg/ha in Kelly to 34,068 kg/ha in Morada.
