【 摘 要 】

The relationship among Moisture Regime in an Entic Haplustoll loamy fragmental over fragmental loamy isohiperthermic mixed super active 0-1% ( evaluated three times per week) and forage production ( evaluated during two harvest) was investigated in a cassava forage crop production system in the Cauca Valley department, Colombia. A sowing rate of 40,000, 71,429 and 100,000 plants ha-1, under a complete randomized block design was used. Significant differences (P < 0.05) on the effect of the amazement of the soil particle size over the available soil moisture were observed. Soil mesopores and soil available water were determinant on forage yield in the first harvest at 0-10 cm depth and in the second harvest at 25-40 depth. The sowing rate did not have significant effect on dry matter production or in the green forage under the environmental conditions of the experimental site.
