Effect of organic fertilizers on the production of turmeric (Curcuma longa L.) seedlings Efecto de abonos orgánicos en la producción de plántulas de cúrcuma (Curcuma longa L.)

Abstract

The cultivation of turmeric, known botanically as Curcuma longa L., is native to India and is distinguished by its characteristic yellow-orange hue, which is why it is called the "golden root." This chromatic attribute has given turmeric a prominent position in the global market, due to the beneficial properties it houses in its rhizome. In this research, the main objective is to evaluate three types of solid organic fertilizers, in addition to a control group, in relation to their influence on the production of turmeric seedlings. The study was carried out in the city of Santo Domingo de los Tsáchilas, specifically in the Santo Domingo canton, at the intersection of Avenida Los Anturios and Franklin Pallo. The research headquarters was the Tsa'chila Higher Technological Institute. To carry out this evaluation, a Completely Randomized Design (DCA) was adopted, in which three types of organic fertilizers were compared together with garden soil. Statistical significance was established using the Tukey test, with a significance level of 0.05%. The methodology used was experimental in nature, in which various variables were measured, including the time necessary for germination, the length of the roots, the number of roots per seedling, the height of the seedlings, the number of leaves per seedling and the diameter of the pseudostem. The results indicated that the fertilizer called "T2 Bocashi" presented superior performance in terms of germination and development of turmeric seedlings.
