Respuesta óptima económica de la fertilización potásica sobre variables agronómicas y productivas del cultivo del banano

Abstract

Banana cultivation represents an important economic activity in Ecuador, its production levels demand large amounts of nutrients, including potassium (K), which without proper management lead to productive and environmental detriments. An experiment was carried out in two locations in the province of El Oro, to measure the response of increasing doses K. The results showed us that the source of K at the level of 525 kg ha-1 year based on potassium nitrate achieved significant results and it was considered as the optimal dose of fertilization (DOF), while the optimal economic dose (DOE) was efficient for determining the maximization of income.
