| Popis: | In order to determine the efficiency and response regarding the use of phosphorus of soybean cultivars, experiments were conducted in the 2013/2014 season, to evaluate 15 soybean genotypes under two phosphorus using a randomized complete block, with three replications. To simulate environments with low and high levels of phosphorus, doses of 40 and 120 kg.ha-1 of P2O5 were applied. Characteristics were evaluated for number of pods per plant, grain yield and using the methodology proposed by Fageria & Kluthcouski (1980), determined efficiency in the use of phosphorus. The environment high phosphorus positively affected the average grain yield in all genotypes, with an increase of 48.9% over the average grain yield in low-phosphorus environment. Cultivars JULIANA RR, M9056 RR, P99R01 and M9144 RR were classified as efficient and responsive as the use of phosphorus. |
