Effects of Inorganic and Foliar Fertilizers on Antioxidant Capacity and Flower Yield of Saffron (Crocus sativus L.)

Abstract Saffron ( Crocus sativus L., Iridaceae) is a highly valued species in the food, medicinal, and nutraceutical industries as coloring, flavoring, therapeutic agent. Its productivity flower production vary depending on different factors, including fertilizer treatment. This study was conducted to evaluate effects of inorganic (NK) combined with organic matter plant densities well influence split foliar application yield saffron. The performance saffron plants revealed that NK vegetal (1%) generally better than effect Treatment fertilizers at recommended optimal concentration prolonged flowering period plants.
