| description | Objective: To evaluate two methods to estimate dry matter availability in mixed pastures in the Amazon region, Peru.
Materials and Methods: The traditional method and the electronic capacitance method with Grass Master Pro equipment were used. A complete randomized block design was used, with two sources of variation: five pastures, three evaluation periods (20, 40 and 60 days) and the average of 15 observation units per pasture. A variance analysis and multiple comparisons of means were performed using Tukey’s test: 5 % probability to compare the existence of significant differences among means. Linear and polynomial regression were also used to estimate the relationship between the two methods. For data processing and analysis, the statistical program R was used.
Results: Actual dry matter values were obtained using the quadrat method. The traditional method and the electronic capacitance method showed significant differences (p < 0,05). Dry matter availability by the traditional method was 3 530,3 kg DM/ha and by the capacitance method 3 942,4 kg DM/ha. With the linear regression, a determination coefficient of R2 = 0,87 was obtained and with the polynomial regression, of R2 = 0,93.
Conclusions: The electronic capacitance method reported average dry matter measurements in the pasture, significantly higher than the traditional method, and showed desirable and concordant characteristics for its use in animal husbandry activity. |
