Effectiveness of biopreparations in rice fertilization in the canton of Nobol (Guayas, Ecuador)

Abstract

Improving the productive level in rice cultivation is an objective for small and medium producers of the San José farm in the canton of Nobol, province of Guayas, who sought to evaluate the effect of organic biopreparations complementary to traditional fertilization in rice (Oryza sativa L.) variety SFL 11. For this research, a completely randomized block design (CBRD) was applied; the treatments are based on (worm humus leachate and fermented from Gliricidia sepium) where T1, at a dose of 3 L/ha; T2, at a dose of 5 L/ha; T3, at a dose of 8 L/ha; T4, with a dosage of 10 L/ha; T5, conventional management with an application of Multifeed foliar fertilizer (N-P-K-Bo-Zn ) at a dose of 1 kg/ha; and T6, absolute control. The Tukey comparison test was applied at 5% significance for the statistical analysis. It was determined that the application of T4 was significantly superior in most of the variables under study. In terms of plant height, an average of 104.37 cm was achieved, with an average of 14.05 tillers per plant and an average of 239.5 panicles/m2, in addition to presenting a greater number of grains per panicle with an average of 138.95, a panicle length superior to the other treatments, with an average of 27.12 cm and a lower percentage of affected grains 5.21%; likewise, the best yield of 8.650.00 kg/ha of paddy rice; therefore, the positive influence of the application of organic biopreparations on the development and productive behavior of the rice crop is evident.
