Effects of foliar application of a byproduct of the two-step olive oil mill process on maize yield
The main objective of this work was to study the effect of foliar fertilization at different doses with a byproduct of the two-step olive oil mill process on the productivity and quality of maize crops (Zea mays, L. cv. Tundra) located in Lora del Río, near Sevilla (Andalusia, Spain). Foliar fertili...

| Resumo: | The main objective of this work was to study the effect of foliar fertilization at different doses with a byproduct of the two-step olive oil mill process on the productivity and quality of maize crops (Zea mays, L. cv. Tundra) located in Lora del Río, near Sevilla (Andalusia, Spain). Foliar fertilizer was applied four times during the season and three different concentrations were tested. Foliar fertilization increased leaf soluble carbohydrate contents, chlorophyll A and B and carotenoids, and increased the leaf concentrations of N, K, Fe, Mn and Zn. Yield was significantly increased by 24% to 14.9 t $\cdot$ ha-1 by the highest dosage of the byproduct, which also caused a 22% increase in kernel number and a 19% increase in grain protein content. |
