Agronomic biofortification of cowpea with selenium by foliar fertilization: effect of doses in three cultivars

Selenium (Se) deficiency in the human population is one of the major nutritional problems in the world. A possible solution is biofortification. Biofortification is a process that increases the element of interest’s concentration in food by fertilizer applications (agronomic biofortification) or by genetic breeding focused on accumulation capacity for this element (genetic biofortification). Thus, the aim of this work was to determine the effect...
