Abstract

---

Among leguminous forages, alfalfa genotypes vary significantly in terms of their potential for weed suppression, herbage productivity, nutritional quality traits, and synthesis of allelopathic compounds. A multi-year study was conducted to determine alfalfa genotypes performance under an organic production system. The study was conducted during the period 2018-2019 at the Bilecik Seyh Edebali University's research trials area. Promising genotypes of alfalfa, including Queen, Prosementi, Taurus, Ludelis, Triade, Nijagara, Ultra, Nardian, Osmanağa, Corsa, Global, Oslava, Occitane, and Costanza alfalfa genotypes were comparatively evaluated. Experiments were conducted in a randomized complete block design (RCBD) with four replicates. The response variables included the density of weed species along with their fresh and dry weights in tested alfalfa genotypes., Additionally,  nutritional quality traits such as relative feed values, dry matter for consumption, neutral detergent fiber, leaf area indexes were also recorded during the course of study. There were statistically significant differences among the genotypes and characteristics examined. It was recorded that Corsa, Global, Prosementi, and Queen genotypes, remained superior by recording the maximum forage yield, quality traits, and weed suppression; thus, these genotypes are recommended for general adoption by alfalfa growers in Turkey
