Initial Weed and Maize Response to Conservation Tillage and Liming in Different Agroecological Conditions

Conservation tillage (CT) is an effective tool for maintaining crop productivity under adverse climate conditions, while its adoption conditioned by the possible negative response of weed. Research with CT and liming (L) was conducted at different experimental sites on acid soils (ES 1 ES 2) to determine maize weediness yield. The treatments used were ST (conventional tillage), CTD (deep loosening), CTS (shallow liming; Ly (CaO) Ln (no CaO). assessment V7 R5 growth stages. Weed density (WD), biomass (WB), weed coverage (WC), species (WSN) determined. highest WD recorded 2 in V7, WB, WC, WSN significantly higher compared ST. Liming affected decrease WC R5. average yield 36% 1. resulted 1, 2, it similar application increased given results indicated positive impact L agroecological despite weediness.
