Abstract


The objective of this study was to evaluate weed characteristics due to application of herbicides oxyfluorfen and pendimethalin at various doses in soybean plants. This research used Randomized Block Design (RBD) Factorial with 2 factors. The first factor was the type of herbicides: oxyfluorfen and pendimethalin. The second factor was herbicide doses: 0, 0.5, 1, 1.5 and 2 kg a.i ha-1. The observed variables were percentage of weed control, percentage of weed coverage, weed species, weed population, and weed dry weight. The results revealed that different types of herbicide applied did affect the percentage of weed control at 21, 35 and 49 days after planting, percentage of weed coverage at 35 and 49 days after planting, weed species at 63 days after planting and weed dry weight at 35 and 49 days after planting. Herbicide doses also influenced the percentage of weed control, percentage of weed coverage, weed species, weed population and weed dry weight at 35 and 63 days after planting. There was an interaction between the types and doses of herbicides on the percentage of weed control at 21 and 63 days after planting and the percentage of weed coverage at 21 and 49 days after planting.
