Evaluación de distanciamientos de siembra en dos variedades de arroz (Oryza sativa L.) en la zona de Babahoyo

SUMMARY The present experimental work was established in the grounds of the Experimental Farm "Palmar" of the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at Km 12 of the Babahoyo - Montalvo highway (CEDEGÉ), between the geographic coordinates of 277438, 26 UTM of West longitude and 110597.97 UTM of South latitude; with a height of 8 m.s.n.m. The zone presents a humid tropical climate, with an average annual temperature of 25.60 ° C; an annual rainfall of 2329.8 mm; relative humidity 82% and 998.2 hours of annual average heliophany. The soil has a flat topography, a loamy clay texture and regular drainage. Seeds of rice SFL-11 and Poderosa were used as seed material, constituting as interacted treatments with planting distances of 0.25 x 0.25; 0.30 x 0.30; 0.35 x 0.35 m and randomly. The experimental design called "Complete Random Blocks" was used, in factorial arrangement A x B, with eight treatments and three repetitions, Factor A includes rice varieties and Factor B transplants distances. All the variables were evaluated with the Tukey test. For the results obtained, it was determined that a favorable response was presented in the evaluation of planting distances in two rice varieties; in the agronomic characteristics of plant height, tillers and panicles / m2, panicle length, grains per panicles and weight of 1000 grains, the SFL-11 variety stood out with random sowing and the highest crop yield and net profit was reported with the SFL-11 variety using random planting distancing. Keywords: rice, planting distances, yield.
