Comportamiento agronómico y valor nutritivo de seis variedades de pastos con fertilización química en la zona de El Empalme

The present investigation was carried in the property of the Association of Cattlemen April 17 of El Empalme, located in the Km 2 of the road El Empalme - Pichincha, in the canton El Empalme, county of the Guayas. It is among the geographical coordinates 01° 06' of South latitude and 79° 29 of longitude west to a height of 73 msnm. The investigation had duration of 120 days. They thought about the following objectives: to) to Determine the agronomic behavior gives the six varieties of grasses fertilized chemically, b) to Establish the nutritious value of the six varieties of grasses, c) to Carry out the economic analysis of the treatments in study. The treatments under study were: T1 common Saboya or Guinea + Fertiforraje, T2 common Saboya or Guinea + Yaramila, T3 Saboya to cultivate Tanzania + Fertiforraje, T4 Saboya to cultivate Tanzania + Yaramila, T5 Saboya to cultivate Tobiata + Fertiforraje, T6 Saboya to cultivate Tobiata + Yaramila, T7 Brachiaria decumbens + Fertiforraje, T8 Brachiaria decumbens + Yaramila, T9 Brachiaria brizhanta + Fertiforraje, T10 Brachiaria brizhanta + Yaramila, T11 Brachiaria Mulatto + Fertiforraje and T12 Brachiaria Mulatto + Yaramila. You uses a factorial arrangement (6x2) prepared at random in the experimental design of complete blocks (DBCA) with 3 repetitions. To establish the differences among the stockings of the treatments the test of multiple ranges it was used from Tukey to 95% of probability and the variation coefficient is expressed in percentage. The variables were analyzed: plant height (cm), number of shafts, number of leaves for plant, relationship hoja/tallo, production of green forage (Tm/ha-1), production of dry matter (Tm MS/ha-1), bromatológic analysis, production costs, utility and relationship benefit/coast. The biggest production of green forage and matter dries off he/she obtained with the treatment T4 (18,01 Tmha-1 and 2,94 TmMS/ha-1), in him the grass Tanzania was used fertilized with Yaramila. The biggest content of protein 4,32% presents it the grass Panicum maximun variety Tobiata fertilized with Yaramila.
