title: Effects of compost application on sunflower (Helianthus annuus L.) yield and some soil enzyme activities in heavy metal-contaminated soils
abstract: Heavy metal accumulation in soils causes environmental pollution, negatively affecting soil microbiota and limiting plant growth and development. This study investigated the effects of different compost doses (0, 1.5%, 3%, and 4.5%) on sunflower (Helianthus annuus L.) growth and soil enzyme activities under high heavy metal content soil conditions. The experiment was conducted with three replications, and morphological plant characteristics (plant height, number of nodes, root length, fresh and
