| dc.description.abstract | Field experiments on the effectiveness and selectivity of herbicides use several  active ingredients; there were Sulfentrazone, Ethyl Pirazosulfuron, and  Oxifluorfen with two varieties, there were Peleton and Kanton Tavi. The  purpose of the study was to discover the most effective and selective herbicide  active ingredients. The study was conducted from February to May 2019. This  study used a randomized block design with seven treatments, namely A  (control), B (oxyfluorfen, Peleton), C (etil pirazosulfuron, Peleton), D  (sulfentrazone, Peleton), E (oxyfluorfen, Kanton Tavi), F (etil pirazosulfuron,  Kanton Tavi), G (sulfentrazone, Kanton Tavi). Each treatment was repeated  four times. The data were analyzed used analysis of variance (ANOVA); further  testing used the DMRT test with a 5% level. The results showed that the  application of herbicides made from sulfentrazone, ethyl pirazosulfuron,  oxyfluorfen in Peleton varieties, and Kanton Tavi could suppress weed growth  in the research area. The best weed control results were shown by herbicide  treatment with sulfentrazone as an active ingredient in the Kanton Tavi  variant. The best long bean production results were demonstrated by herbicide  treatment with sulfentrazone in Peleton varieties. The application of herbicides  with active oxyfluorfen made no symptoms of phytotoxicity but decreased the  yield of kanton tavi varieties and peleton varieties. | en_US |
