Fertilization increases longleaf and slash pine flower and cone crops in Louisiana

Abstract

Annually fertilizing heavily thinned cultivated stands with 1,000 pounds per acre of 15-25-10 markedly increased female flower and cone production. Flowering was also related to March-through-July rainfall in the previous year and to the size of the flower crop two years earlier. Annual fertilization of seed production areas appears practical if mortality of female strobili can be minimized.
