“Efectos de bioestimulantes orgánicos sobre comportamiento agronómico de dos variedades de arroz (Oryza sativa L.), en la zona de Pimocha”.

SUMMARY The present experimental work was established in the Rcto. San Vicente, belonging to the Pimocha parish, of the Babahoyo canton belonging to Mr. Johnny Fernando Inga López. The geographical coordinates 277438.26 UTM of longitude West and 110597.97 UTM of South latitude; with a height of 8 masl. 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. The treatments consisted of the rice varieties Iniap 15 and Iniap 16 and the biostimulants were Radix Cal in doses of 5.0 L / ha; Radix Tim in a dose of 3.0 L / ha; Solum H80 in a dose of 2.0 kg and the absolute control. The experimental design of Complete Random Blocks was used, in factorial arrangement A x B, where the factor A was the rice varieties and the factor B the biostimulant products, with eight treatments and three repetitions. The averages of the treatments were compared with the Tukey multiple range test at 95% probability. All the agricultural practices that the crop needs for its normal development were carried out, such as land preparation, sowing, weed control, irrigation, fertilization, phytosanitary control and harvesting. The variables evaluated were days to flowering, height of the plant, number of tillers and panicles per square meter, length of the panicles, number of grains per panicle, weight of 1000 grains, crop yield and economic analysis. For the results obtained it was determined that the Iniap 16 variety took time to flower, unlike the Iniap 15 variety that flourished in less time; Regarding the agronomic characteristics of plant height, tillers and panicles / m2, panicle length, grains per panicles and weight of 1000 grains, the Iniap 15 variety stood out using Radix Tim in a dose of 3.0 L / ha and the variety Iniap 15 with application of Radix Tim in doses of 3.0 L / ha obtained higher yield and net profit with 5294.5 kg / ha and net profit of $ 635.21.
