Comportamiento agronómico del cultivo de maiz (Zea mays) usando semilla tratada con tiametoxam.Quevedo.

This research was conducted in the ownership of Mr. Cesar Herrera, located at Km 9 via Quevedo the splice enclosure San Luis, Canton Mocache Rivers Province, whose location is 1 ° 3'50 .5'' south latitude, 79 º 31 ' 34'' west longitude and 79 meters. The work was to evaluate the agronomic performance of maize (Zea Mays) Tiametoxam using treated seed. We tested the following treatment: large flat corn T1 (PG), witness; T2 large flat corn (PG) + Thiodicarb, large flat corn T3 (PG) + Tiametoxam, large flat corn T4 (PG) + Thiodicarb) + Tiametoxam; T5 Corn Ball girl (BCH) control; Corn Ball girl (BCH) + Thiodicarb; T7 Corn Ball girl (BCH) + Tiametoxam; T8 Corn Ball girl (BCH) + Thiodicarb) + Tiametoxam. Experimental design was used "Randomized Complete" (DCA) with factorial arrangement of 2 x 4 to 8 treatments, 4 replications. From planting Emergency evaluated, plant height, stem diameter, at harvest, were evaluated number of harvested plants, number of ears harvested number of healthy ears. Number of diseased pods, weight of ears, gopher weight, weight of 100 grains, Performance, and applied the Tukey test at 95% probability to determine the statistical difference between treatment means. The emergence of the seed evaluated at 3, 6 and 9 after sowing and determined that there was no statistical difference between treatments, with the coefficient of variation 7.97; 6.53 and 6.38% respectively. The plant height were assessed at 15, 30, 45 and 60 days after planting, there were no statistically significant differences between treatments, with the coefficient of variation 6.78; 5.12, 3.36 and 3.09% respectively. Stem diameters were evaluated at 15, 30, 45 and 60 days after planting were not statistically significant differences between treatments with the coefficient of variation 8.87; 4.39, 2.58 and 3.53% respectively. The mean number of harvested plants, moisture corn harvested and found no statistically significant differences between treatments, with the coefficient of variation 8.20; 7.83 and 2.24% respectively The average weight of 100 seeds, total weight, grain weight and weight gopher determined that there were no statistically significant differences between treatments, with the coefficient of variation 14.93; 11.63, 11.99 and 11.11% respectively. The averages of the variables yield / ha, (qq / ha) which do not reflect significant differences statistically significant differences between xv treatments, with the coefficient of variation 11.66%. The benefit / cost ratio ranged between 0.93 and0.94 for all treatments. The treatment was the highest performing T4 large flat Corn (PG) + + Thiod+Tiam with 0.94
