“…This indicates that besides the natural parthenocarpy level of the cultivar, the yield was favored by the soil worm castings application, since this, in addition to increasing nutrients like nitrogen, phosphorus, potassium, calcium, magnesium, and microelements availability (Olivares-Campos et al, 2012), provides active substances with phytohormonal effects (Domínguez et al, 2010;Calvo et al, 2014;Aremu et al, 2015). These promote fruit growth (Rodríguez-Dimas et al, 2007;Ayala-Tafoya et al, 2020), and induce increased performance (Reyes-Pérez et al, 2017, Ayala-Tafoya et al, 2020. Ayala-Tafoya et al (2020) discuss that auxins: 1-naphthaleneacetic acid (0.45%)1naphthaleneacetamide (1.2%) increased the fruit set percentage, number of fruits per plant, and yield in zucchini.…”
