Comportamiento agronómico y productivo de la línea promisoria de arroz (Oryza sp.) L-17 cultivada en la zona de Pimocha, Provincia Los Ríos

Rice (Oryza sativa L.) is the main food of inhabitants in developing countries and is the second most consumed cereal in the world. Its global demand increases due to population growth and consumption models in different regions. Rice is one of the most important crops for Ecuador, generating a significant contribution to the economy, in addition to contributing to and guaranteeing the food security of the population and generating thousands of direct and indirect jobs throughout the production chain. The progress of the sector in productivity issues during the last decades has been slow. This project aims to determine the agronomic and productive behavior of the promising L-17 rice line cultivated in the Pimocha area, province of Los Ríos. In this research, a methodology was carried out, with a non-parametric statistical design with the use of Tukey analysis including comparisons of means. For the analysis, three repetitions will be considered (three samplings with areas of 4 m² taken in one hectare of crop) and two cultivars (L-17 and SFL-11). The technique used to evaluate the plots was direct counting of individuals, tillers, panicles, grains, the distance between plant and row and estimation of yield, two treatments were used. Regarding the results, the promising line L-17 showed a greater number of panicles, which reached a value of 21.68, compared to the SFL-11 variety, which obtained a lower number of panicles 19.27. Line L-17 had a higher percentage (6.04%) of wasted grain, compared to the commercial line, SFL-11, which had a lower amount of wasted grain (5.5%). It is found that the promising line L-17 has a distance of 36 cm from the commercial SFL 11 of 34.6 cm, which results in the smaller the distance, the greater the number of plants. Although there are similarities in the agronomic characteristics of the SFL-11 line and the promising L-37 line, it is the latter that really shines in terms of performance and creates an impressive range of 6.5 to 7 tons per year. In conclusion, the promising line L-17 is distinguished from the commercial line SFL 11 by having a high significance of difference, both in character, yield and production cost, which makes it a promising line for farmers.
