Шошго нэмэх | Тойм: | The present investigation was carried out during the rainy season of 2019, at the Oasis de Paz farm of Mr. Ney Rodríguez Cagua, in the Palmasola fense located 3 km from the Pijullo - Ventanas road. The Emblema 777 corn hybrid was used, four treatments were formulated. The experimental design of complete random blocks (BCA) with four repetitions was used and to determine the statistical differences between the means of the treatments, the Tukey test was used at 95% probability. The variables studied were days to flowering, plant height, stem diameter, ear length, ear diameter, number of rows, grains per row, weight of 100 grains and yield. The application of the Ihumix DG was made 8 days after germination. The variables Days to flowering, plant height, corncob length, corncob diameter, number of rows and grains per row, did not show statistical significance. The performance variable reported high statistical significance. Treatment 2 (75% urea + 20 kg / ha Ihumix DG) achieved the highest yield with 6387.58 kg / ha, followed by treatment 1 (100% urea dose). Treatment 1 (100% urea) obtained the highest benefit / cost ratio (0,69) for having the lowest cost than the other treatments. |
