Abstract


The application of the TOT (No- Till) farming system with herbicides aims to prepare the land so that plants can grow and produe well by still paying attention to the ecological balance of the environment. The aims of this study is to determine the effect of the no-till farming system and the type of herbicide as well as to figure out the appropriate treatment for weed dominance and growth and yield of sweet corn. This study was conductedfrom October 2021 to January 2022 in Bolihuangga Village, Limboto Subdistrict, Gorontalo Regency, Gorontalo Province. It employed a factorial Randomized Block Design where the first factor was the no-till system (T) and the second factor was the types of herbicides (H). The data analysis used Analysis of variance (ANOVA) and furthertest with a 5% least significance difference test, While the weeds were analyzed using quadratic method. Based on the results of the study, it was known that the no-till farming system had an effect, and the types of herbicide did not affect the weed population and the growth and yield of sweet corn. The no-till system at treatments of 2.4, and 6 weeks after planting (WAP) contributed to plant height. Meanwhile, treatments of 2 and 4 weeks after planting (WAP) contributed to the number of leaves. The no-till system factor obtained the best treatment, namely in the control treatment, while the herbicide type factor obtained the best treatmentin the contact herbicide treatment.
