Response of five eco-physiological parameters, to the application of potassium in sunflower (Asteraceae), under semi-arid climate

Descripción del Articulo

In order to know the effect of three levels of potassium on five eco-physiological parameters in sunflower, open-pollinated achenes Victory cultivar, were sown at a density of 11.08 plants m-2 with a fertilization of 100N-50P kg ha-1 N=nitrogen, P= phosphorous, K= potassium. Traits evaluated were: a...
