Abstract

This work aimed to select the most efficient genotypes in phosphorus absorption and utilization in cerrado soils during corn second crop. The essay was constituted of 47 treatments (genotypes) and conducted at the experimental area of the Universidade Federal do Tocantins, Gurupi Campus. In order to simulate environments with high and low levels of phosphorus, doses of 25 and 113 kg ha^-1de P₂O₅ were applied in the seeding, respectively. In order to identify the cultivars adequate to the environments, the study applied the methodology that suggest cultivar classification should be conducted according to use efficiency and response to phosphorus application (efficiency and response). It was concluded that the genotypes efficient in phosphorus absorption and utilization and responsive to P increase were UFVM77-0331, UFVM77-0307, UFVM77-0333, UFVM77-0381, UFVM77-0313, UFVM77-0305, UFVM77-0377 and UFVM77-0345.
