Efecto de la aplicación de Ascophyllum nodosum con Ácidos húmicos y fúlvicos, sobre el rendimiento del cultivo de arroz (Oryza sativa L.), bajo riego, en la zona de Babahoyo

IX. SUMMARY The present research work was carried out in the lands of the Experimental Farm "Palmar", belonging to the Faculty of Agricultural Sciences of the Technical University of Babahoyo, located at Km. 11,5 of the Babahoyo-Montalvo road. Its objective was to evaluate the effect of the combination Ascophyllum nodosum with humic and fulvic acids, on the yield of rice cultivation under irrigation, in the Babahoyo area. The sowing material used was the rice variety SFL-09, two Stimplex products (Ascophyllum nodosum) and Lonite (humic and fulvic acids) were evaluated, in different doses and mixtures between both, distributed in 9 treatments and 3 repetitions, using the The experimental design blocks complete at random. The mean comparisons were made with the Tukey test at 95% probability. The treatments were applied in two stages of the culture at 15 and 30 days after the transplant. For an optimal development of the crop, the corresponding agricultural tasks were carried out, among which weed control, fertilization, irrigation, phytosanitary control and harvesting are highlighted. The variables height of plant to harvest, number of tillers and panicles per square meter, length of panicle, number of grains per panicles, weight of thousand grains, days to flowering, leaf analysis, days to maturation, grain physiology, were evaluated. grain-straw ratio, yield per hectare and economic analysis. The results obtained determined that the incorporation of marine algae together with humic acids, have a good effectiveness on the agronomic characteristics of the plants. The variables plant height, days to flowering, days to ripening and grain-straw ratio did not show significant differences. The application of Stimplex + Lonite both at doses of 0.75 L/ ha and 1 L/ha, allowed obtaining the highest values of panicle length (27,40 cm), number of grains per panicle (166), weight of 1000 grains (27,87 g), while the highest plant height (108,03 cm) and number of panicles per square meter (450) were obtained with the application of Stimplex + Lonite in a dose of 1 L/ha. The Witness N-P-K treatments, without the application of marine algae, humic and fulvic acids, showed no increase in the agronomic variables evaluated in the trial. The highest yield of the crop was registered with the application of Stimplex + Lonite both in doses of 1 L/ha with 7480,43 kg / ha, and obtained the highest net benefit with $ 913,90
