Abstract
ABSTRACT Table cassava cultivars efficient in the use of phosphorus (P) and responsive to phosphate fertilization represent a crop option for regions with low availability of the nutrient and for crops using technological packages, such as investment in fertilization. The objective of the study was to classify table cassava cultivars regarding efficiency and responsiveness to P application in two agricultural crops. For this, four table cassava cultivars (Água Morna, BRS Gema de Ovo, Recife and Venâncio) were evaluated under conditions of low P availability (and without phosphate fertilization) and high availability (and fertilized with 240 kg ha-1 of P2O5). The Água Morna cultivar proved to be efficient and responsive in the two harvests evaluated. Only the Venâncio cultivar was classified as non-efficient. There was variation in the response of the Recife cultivar between the crops evaluated.
