Comportamiento agronómico y valor nutritivo de seis gramíneas forrajeras con fertilización química en la Zona de Pichincha

The present investigation had for objective, to evaluate the agronomic behavior and nutritious value of six gramineous forajeras with chemical fertilization in the area of Pichincha. This investigation was carried out, in the canton Pichincha of the county of Manabí; Located among the geographical coordinates 01° 06' of South latitude and 79° 29 of longitude West to a height of 73 msnm.

Six varieties of grasses were used with a dose of chemical fertilizer with three repetitions, prepared at random in complete blocks DBCA. For the difference among the stockings of the treatments the test of multiple range was used from Tukey to the 0,05 of probability. Of the results settles down that as for number of leaves the treatment stands out T3 I pasture Tobiata with 151,33 leaves, the best relationship leaf/shaft 7,67 to the 63 days one has in the treatment T4 that corresponds to the grass Brachiaria decumbens, The biggest height of plant 168 cm, bigger tallos32 number, 67 shafts, the best production of biomass forrajera 34,33 Tm/ha-1, 37,33 Tm/ha-1 and 36,67 Tm/ha-1 to the 21, 42, and 63 days respectively, the best content of gross energy 4.597,92 Kcal/kg and, the biggest profitability $ 3,50 correspond to grass Saboya to cultivate Tanzania fertilized with Fertiforraje to reason of 125 kilos/ha-1. To obtain the best profitability it is recommended to cultivate the grass Tanzania to with 40000 plants for hectare and to fertilize with 125 kilos of fertiforraje/ha-1. Key Words: Gramineous, forajeras, varieties, grasses.
