Efeito de diferentes dosagens de fte na germinação e crescimento inicial do arroz (Oryza Sativa L.)

Abstract

Rice (Oryza sativa L.) is the second most cultivated cereal, considered the main food for the global population. The production is directly affected by the nutritional quality of the crop, with the supply of micronutrients being essential for the development of the culture, significantly impacting the quality of rice cultivation. The aim of this study is to analyze the use of different doses of FTE BR12 on the germination and initial growth of rice, aiming to determine the limits for the proper development of the culture in its initial development phase. The experiment was conducted in the Plant Biology laboratory at PUC GO, in plots arranged in a completely randomized experimental design (CRD), distributed in five treatments: 50; 100; 200; 400 kg/ha of FTE BR-12, and the control (0 kg/ha). Each treatment was established with four replications, and the experiment lasted for 20 days. Statistical analysis was performed through ANOVA, where germination parameters, plant height, root size, and plant dry matter were analyzed. The results observed in this study indicated that the application of FTE BR-12 at the doses used in the treatments did not significantly affect the analyzed parameters at the 5% significance level. It is concluded that rice in its initial growth and development phase was not affected by different doses of FTE (ranging from 50 kg/ha to 400 kg/ha), as observed in the control. Possibly, during the initial development phase, the requirement for micronutrients is low, and the amount existing in the seed reserves is sufficient to meet the plant's needs.
