Abstract
Abstract A field experiment was conducted during the 2023–2024 agricultural season at the University of Al-Qasim Green to assess the response of oat varieties to sunflower residues and their effects on yield, yield components, and associated weeds. The experiment followed a randomized complete block design (RCBD) with a split-plot arrangement, testing three oat varieties (Karlob, Genzania, Shifa) and three sunflower residue treatments (Control, residues, and fermented residues). Statistical analysis revealed that the Shifa variety had the lowest average weed density and dry weight (27.89, 28.55, 29.44 plants m⁻ 2 and 11.68 g m⁻ 2 ) across the study, compared to Karlob, which recorded the highest weed density. Genzania showed the highest weed dry weight (13.54 g m⁻ 2 ) but excelled in panicle count (351.00 panicles m⁻ 2 ). Karlob achieved the highest grain count per panicle and 1000-grain weight (45.333 grains panicle⁻¹, 30.569 g), while Shifa produced the highest overall grain yield (4.318 tons ha⁻¹). The addition of fermented sunflower residues significantly reduced weed density (14.33, 13.00, 13.89 plants m⁻ 2 ) and dry weight (4.65 g m⁻ 2 ). Residues also enhanced yield components, resulting in the highest panicle number (336.22 panicles m⁻ 2 ), grains per panicle (44.69 grains panicle⁻¹), 1000-grain weight (30.059 g), and grain yield (4.503 tons ha⁻¹). In conclusion, Shifa was the most resilient to allelopathic effects and displayed strong competitive ability, maintaining consistent yield advantages across treatments.
