Determinación de la edad y la hora de corte sobre la concentración de carbohidratos solubles en el Panicum maximum (Pasto Guinea)

Abstract

In the province of Manabi, Canton El Carmen, performed the evaluation age and the cutoff time on the concentration of soluble carbohydrates in Panicum maximum. Considering the ages 45 and 60 days for factor A and (8, 10, 12. 14) hours for factor B respectively. The investigation took 120 days involving 32 experimental units of 3x4m, with total areas of 384m2. The distribution of treatments was performed by a completely randomized Block Design according to a factorial arrangement with four replications. The results show that the highest concentration of soluble carbohydrates is obtained after 60 days with a 21.98% and 21.78% in 14 hours. The most forage production was gotten after 60 days of pasture age, with 31.60t / ha / cut and dry matter 7.19 Tn / ha / cut. The best treatment of protein was reached at 45 days of age with 11.97%. Therefore it recommends to harvest the grass at 60 days and 14 hours because the more productive and economic behavior was recorded.
