Evaluación del uso de naturcomplet G, combinado con microelementos zinc y boro en el cultivo de arroz Oryza sativa L.

Abstract:

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%.
