Abstract
Mixing two or more herbicides is one of efforts to increase herbicide efficacy in controlling weeds, where this weed control is needed to improve soybean yield. The purpose of this study was to determine the effective dose of mixing herbicides pendimethalin and sulfentrazone and to evaluate its effect to weeds and soybean yield. This study was conducted in June to September 2019, using Randomized Completely Block Design (RCBD) with 8 treatments. Variables observed were weed dry weight, phytotoxicity, number of pods per plant, number of seeds per plant, seed weight per plant, weight of 100 seeds and dry seed yield. The results revealed that the application of mixed herbicides pendimethalin and sulfentrazone gave an effect to weed dry weight, phytotoxity, seed weight per plant, weight of 100 seeds and dry seed yield. The application of 1 kg b.a ha−1 pendimethalin and 0.5 kg b.a ha−1 has decreased the weed dry weight and phytotoxicity. However, it has also increased the seed weight per plant, weight of 100 seeds and dry seed yield.
