Resumen
Se analizó el efecto de la fertilización orgánica combinada con microelementos
zinc y boro en el cultivo de arroz (Oryza sativa L.). Se realizó en la hacienda
“Martiz”, provincia Guayas con el objetivo de plantear mecanismos alternativos
para el manejo nutricional del cultivo. Se utilizó un diseño de bloques
completamente al azar, con arreglo factorial 2x4, con 8 tratamientos y 4
repeticiones. Con el programa INFOSTAT se realizó el análisis de varianza y
la prueba de Tukey (< 0,05). Días a la floración y ciclo vegetativo, presentaron
valores iguales estadísticamente. La combinación del fertilizante B-Zn con
dosis 3-5 kg/ha con el Naturcomplet-G a la dosis de 5 kg/ha, mostró mejores
resultados en altura de la planta (121.5 cm), Longitud de panícula (26.75 cm)
y peso de 1000 semillas (26.75 gramos). El fertilizante B-Zn con dosis 3-5
kg/ha, alcanzó los mejores valores en altura de planta, longitud de panícula,
número de panículas, número de granos por panícula, peso de 1000 semillas
y rendimiento agrícola. En los tratamientos que se aplicó el abono orgánico
Naturcomplet-G, presentaron valores más altos altura de planta, longitud de
panícula, número de panículas, número de granos por panícula, peso de 1000
semillas y rendimiento agrícola. El rendimiento agrícola logró 5921 kg/ha en
la combinación del fertilizante B-Zn con dosis 3-5 kg/ha con el Naturcomplet-G
aladosisde15kg/ha.Eltratamiento2(fertilizanteB-Zncondosis1-3kg/hacon
Naturcomplet-G con dosis 15 kg/ha) fue el más rentable con tasa de
retorno marginal de 39%.
The effect of organic fertilization combined with zinc and boron microelements in rice cultivation (Oryza sativa L.) was analyzed. It was carried out in the hacienda "Martiz", province of Guayas, with the objective of proposing alternative mechanisms for the nutritional management of the crop. A completely random block design was used, with 2x4 factorial arrangement, with 8 treatments and 4 repetitions. The variance analysis and the Tukey test (<0.05) were performed with the INFOSTAT program. Days at flowering and vegetative cycle, they presented statistically equal values. The combination of the fertilizer B-Zn with dose 3-5 kg / ha with the Naturcomplet-G at the dose of 5 kg / ha, showed better results in height of the plant (121.5 cm), Panicle length (26.75 cm) and weight of 1000 seeds (26.75 grams). The fertilizer B-Zn with doses 3-5 kg / ha, reached the best values in plant height, panicle length, number of panicles, number of grains per panicle, weight of 1000 seeds and agricultural yield. In the treatments that applied the Naturcomplet-G organic fertilizer, higher values of plant height, panicle length, number of panicles, number of grains per panicle, weight of 1000 seeds and agricultural yield were presented. The agricultural yield achieved 5921 kg / ha in the combination of fertilizer B-Zn with a dose of 3-5 kg / ha with Naturcomplet-G at a dose of 15 kg / ha. Treatment 2 (fertilizer B-Zn with dose 1-3 kg / ha with Naturcomplet-G with dose 15 kg / ha) was the most profitable with a marginal rate of return of 39%.
