          Abstract

          Abstract Analyses of potential sources and products that aim to balance nutrients in soil and plants; improve physical, mineral, and biological attributes of soil; and reduce environmental impacts require greater attention. Therefore, the aim of this study was to evaluate the agronomic efficiency of organomineral fertilizers (OMFs) in Atlantic potato cultivars. The experimental design was a randomized complete block design, with four treatments and six replicates. The treatments consisted of NPK mineral fertilizers (recommended according to soil analysis and nutritional crop requirements) as a control and NPK plus OMF according to composition and form of application (planting, ridging, and leaf), referred to as managements A and B, which indicate the amount of nutrients that the plants received. Therefore, treatments with OMF were designated as follows: P-OMF(A): organomineral fertilizer management applied through the planting furrow; PR-OMF (B): organomineral fertilizer management applied through the planting and ridging, and PR-OMF (B) + L-OMF (B): organomineral fertilizer management applied through the planting and ridging and by leaf application. The applications of P-OMF (A) and PR-OMF (B) + L-OMF (B) resulted in positive effects on special class production and total productivity of Atlantic potato tubers, which increased by 12% to 16% and 11% to 15.5%, respectively. The application of PR-OMF (B) + L-OMF (B) improved the soluble solid content by 2.7% compared to the control (absence of OMF application). Therefore, organomineral fertilizers have the potential to improve the quantitative and qualitative attributes of potatoes.

          Resumen El análisis de las posibles fuentes y productos que apuntan a equilibrar los nutrientes en el suelo y las plantas, mejorar los atributos físicos, minerales y biológicos del suelo y reducir los impactos ambientales necesitan más atención. En este sentido, el objetivo de este estudio fue evaluar la eficiencia agronómica de los fertilizantes organominerales (OMF) en papa, cultivar Atlantic. El diseño experimental fue un bloque completo aleatorizado, con cuatro tratamientos y seis repeticiones. Los tratamientos consistieron en el control -fertilizantes minerales NPK (recomendado de acuerdo con el análisis del suelo y los requerimientos nutricionales del cultivo); y NPK más OMF de acuerdo con: composición y forma de aplicación (plantación, crestas y hojas), que fue llamado a lo manejo A y B. Lo manejo A y B se relaciona con las tasas de nutrientes que recibieron las plantas. Por lo tanto, los tratamientos con OMF se designaron como: P-OMF (A): manejo de fertilizantes organominerales (A) aplicado en el surco de siembra; PR-OMF (B): manejo de fertilizantes organominerales (B) aplicada en la siembra y la formación de surcos y PR-OMF + L-OMF (C): manejo de fertilizantes organominerales (B) aplicada en la siembra, la formación de surcos y la aplicación de hojas. Las aplicaciones de P-OMF (A) y PR- PR-OMF (B)+ L-OMF (B) dan como resultado una acción positiva para la producción de Clase Especial y la productividad total de los tubérculos del cultivar Atlantic, con incrementos entre 12 y 16% y 11 a 15.5%, respectivamente. La aplicación de PR-OMF (B)+ L-OMF (B) mejora en un 2.7% el contenido de sólidos solubles, en comparación con la ausencia de aplicación de OMF. Por lo tanto, los fertilizantes organominerales presentan potencial para mejorar los atributos cuantitativos y cualitativos de las papas.

            The Importance of Nutrient Management for Potato Production Part I: Plant Nutrition and Yield

            As part of a successful agronomic strategy, adequate nutrient management of the potato crop is essential throughout the whole growth period. In this review, the importance of balanced fertilisation for potato yield formation and yield security is addressed by taking advantage of the results of field trials and existing literature. The most important roles of the macronutrients nitrogen, phosphorous, potassium, magnesium, calcium and sulphur in the plant and their importance for yield formation in potato are reviewed. Fertilisation practices in potato production are discussed. Due to their various functions in plant metabolism, the impact of plant nutrients on potato yield is complex. Therefore, interactions with abiotic and biotic factors, for instance interactions between two different plant nutrients in the soil and the plant, are taken into account.
