Interacción de tres dosis de fertilización edáfica con extracto de algas marinas sobre el rendimiento del cultivo de arroz (Oryza sativa L.), en la zona de Babahoyo”

This experimental work was carried out on the grounds of the "Palmar" Experimental Farm, belonging to the Faculty of Agricultural Sciences of the Technical University of Babahoyo. The objective was to evaluate the effects of the interaction of three doses of edaphic fertilization with extracts of seaweed on the performance of the rice crop. The test was carried out under an experimental design of divided plots, with 3 treatments (dose of soil fertilization), 5 sub-treatments (dose of algae extracts and control) and 3 repetitions. During the development of the trial, agronomic practices were carried out that required crop management. There was variability in the growth of the plants treated with Fertiestim and Seaweed Extract in the proposed doses on the untreated control. The results show that there was a greater number of tillers per square meter applying Fertiestim 1.0 L/ha plus the fertilization program 161-69-90-48 kg / ha (N-P-K-S). The variables days to flowering and harvest did not show statistical significance in the evaluations carried out and in none of the factors studied. Greater number of grains was found by applying 161-69-90-48 kg/ha (NPKS) plus Fertiestim 1.0 L/ha, being the treatment 161-69-90-48 kg/ha (NPKS) plus Fertiestim 1.0 L/ha who achieved the highest yield 6504,07 kg/ha. Treatment 115-46-60-24 kg / ha (N-P-K-S) plus Fertiestim 1.0 L/ha obtained the greatest benefit
