Respuesta de una mezcla forrajera de clima frio a cuatro niveles de fertilización química

Due to the grasses losses for the inadequate use of chemical fertilizers in the country property Guagrabamba and the area of Machachi, were carried out a study with four levels of chemical fertilization in a mixture forager looking for an alternative to increase the production and productivity; the investigation was carried out in the country property Guagrabamba, in Aloag, Mejía canton, county of Pichincha, located in the coordinates: W = 65 - 84; S=175; N = 9947264.624; AND = 770264.424; at 2850 (msnm); the investigation lasted four months in field. The treatments for this investigation were four fertilizer levels 8-24-24 (T1 150kg ha-1, T2 200kg ha-1, T3 250kg ha-1 and T4 300kg ha-1); that they prepared at random in a Design of Complete Blocks (DBCA), with four repetitions. To determine differences among the treatments, the test of multiple ranges was used from Tukey to 0.05% of probability. Of the results settles down that inside the agronomic behavior of the mixture forager, in botanical composition, the biggest percentage of gramineous one has with the treatment T1 (86.50%) in the second evaluation, the biggest percentage of leguminous one has with the T2 (24.00%) in the first evaluation; and, the biggest percentage of overgrowths one has with the T2 (3.75%) in the first evaluation. The best protein content (23.44%), to the 47 days in the treatment T4 that corresponds to the fertilization with 8-24-24 to reason of 300 kg/ha-1. bigger relationship benefice/coast 15.42 one has with the treatment T1 in which was fertilized with 150 kg of 8-24-24 ha-1.
