Descrição: dc.descriptionSelenium (Se) as selenite and phosphorus (P) have similarities in uptake and assimilation by plants. Selenium content in cowpea grains might be affected by P, which could affect Se and P concentration in other plant tissues and the biosynthesis of sugars and chlorophyll. This study investigated the effects of Se and P interaction on cowpea plants grown under pot conditions. The experiment involved two cultivars, BRS Xiquexique and BRS Tumucumaque, and a 5 × 2 interaction between five rates of Se (0, 5, 10, 20, and 40 g ha−1) and two rates of P (low and adequate P). The results showed that adequate P supply led to the highest dry mass production and Se concentration in shoots, roots, and grains, starting at the rate of 5 g ha−1 of Se. The Se rates also had an effect on chlorophyll and carotenoids concentrations, and the combined application of Se and P increased the total sugar concentration in the grain. However, low P supply decreased Se accumulation in cowpea seeds. The study highlighted that the interaction between Se and P affected cowpea yield and growth, and an adequate supply of P in the soil increased Se accumulation in cowpea grains. The study also suggested that lower doses of Se increased sugar and pigment contents, but high doses of Se had a negative impact on cowpea growth, regardless of P supply, resulting in reduced grain yield.-
