Abstract
Los suelos agrícolas presentan cada vez un mayor deterioro y con ello la disminución de su productividad. Las causas principales de la problemática son la utilización masiva de fertilizantes minerales y productos fitosanitarios, lo cual genera una dependencia a mediano y largo plazo que a su vez ocasiona un deterioro en el suelo y genera impactos negativos en el ecosistema. Una alternativa al presente problema es la incorporación de enmiendas orgánicas con una visión encaminada a la complementación de fertilizantes minerales aplicados y con ello alcanzar la productividad deseada sin afectar los costos de producción. El objetivo principal en la presente investigación fue evaluar el efecto de enmiendas orgánicas en el crecimiento, desarrollo y productividad en el cultivo de tomate riñón (Solanum lycopersicum) de la variedad (Pietro), en el cantón Ibarra, Provincia de Imbabura. Se implementó un Diseño de Bloques Completamente al Azar con cuatro tratamientos, tres tipos de enmiendas orgánicas (sedimentos de laguna, ovinasa, vermicompost) y un testigo, con una dosificación de 50 t ha-1. Los resultados obtenidos indicaron beneficios en la variable morfofisiológica (días a la floración), obteniendo un valor de 29,33 días con la incorporación de sedimentos de laguna frente al resto de enmiendas utilizadas, así como resultados positivos de productividad en las variables (número de frutos por racimo con un valor de 5,60 frutos; tamaño de fruto dando como resultado 8,94 cm; rendimiento por planta obteniendo 0,51 kg ha-1 y rendimiento por hectárea con un valor de 121390,31 kg ha-1). Esto demuestra que la utilización de enmiendas orgánicas como complementación a la fertilización es una alternativa eficiente para satisfacer las necesidades del cultivo y alcanzar los rendimientos esperados.
Agricultural soils are increasingly deteriorating and, as a result, their productivity is decreasing. The main causes of this problem are the massive use of mineral fertilizers and phytosanitary products, which generates a medium and long-term dependence that in turn causes soil deterioration and negative impacts on the ecosystem. An alternative to the present problem is the incorporation of organic amendments with a vision aimed at complementing the mineral fertilizers applied and thus achieving the desired productivity without affecting production costs. The main objective of this research was to evaluate the effect of organic amendments on the growth, development, and productivity of kidney tomato (Solanum Lycopersicum) of the variety (Pietro), in the canton of Ibarra, Imbabura Province. A Completely Randomized Block Design was implemented with four treatments, three types of organic amendments (lagoon sediments, ovine, vermicompost), and a control, with a dosage of 50 t ha-1. The results obtained indicated benefits in the morpho-physiological variable (days to flowering), obtaining a value of 29.33 days with the incorporation of lagoon sediments compared to the rest of the amendments used, as well as positive productivity results in the variables (number of fruits per bunch with a value of 5.60 fruits; fruit size resulting in 8.94 cm; yield per plant obtaining 0.51 kg ha-1 and yield per hectare with a value of 121390.31 kg ha-1). This shows that the use of organic amendments as a complement to fertilization is an efficient alternative to meet the needs of the crop and achieve the expected yields.
