    Effect of fertilization on the production of female flowers in Stone pine (Pinus pinea L.)
    Pinus pinea L., commonly known as Stone pine, is famous for its edible seeds, called pine nuts. It is native to the Mediterranean area, and requires between 400-800 mm annual rainfall and 4-6 dry months for fruiting. Fertilizers, meanwhile, have demonstrated the capability to increase crop yields and improve product quality. Moreover, fertilization promotes root development and aerial plant growth, thereby contributing to the efficient use of soil and water (Sotomayor et al. 2001). Research on the effects of fertilization is readily available on walnut, chestnut and other species that produce edible seeds or nuts

    Effect of fertilization on Pinus pinea cone to seed and kernel yields
    Stone pine (Pinus pinea L.) is a species of economic interest mainly due to its pine nuts, the most expensive nut in the world. Despite the high value of pine nuts, cones are mainly harvested from unmanaged forests. Therefore, research and its applications are needed to develop nutritional management techniques among other cultivation practices intened to boost production. This study evaluated the effect of fertilization on cone production and quality (cone weight and size, number of seeds and kernels, and health status), which in turn may affect cone to seed and cone to kernel yields. Fertilization consisted of two applications of macro and micronutrients in two adult plantations twice in the growing season (in spring and fall). Morphometric variables, cone production per tree and cone health were evaluated during two years after fertilization. Fertilization effect on cone production was positive and significant in both years, with variations between years. Most of the morphometric variables were positively impacted by fertilization, including cone diameter (3.5% increase), kernel weight and length (7.7% and 2.7% increase, respectively), and total seed and kernel weight per cone (20.9% and 18.6% increase, respectively). Fertilized stone pine trees increased production and quality of cones, seeds and kernels, but did not increase cone to seed or kernel yields. However, fertilization increased type II seed damage by 45.4% and 18.9% in 2020 and 2021, respectively. The results obtained in this research may help producers adopt cultural practices to boost pine nut production.
