The study was conducted at the Agriculture Faculty Farm of the Department of Horticulture, Nangarhar University, Afghanistan during the spring season of 2019, aiming to determine the effects of different potting mixtures on the germination and seedling growth of marigold (Tagetes erecta). Among 12 explored treatments, T7 (soil + coarse sand + rotten wheat straw + FYM) had the highest seed germination (80%). T3 (soil + coarse sand + rice husk + FYM) and T9 (soil + coarse sand + forest soil + FYM) exhibited higher seedling growth, as well as plant fresh and dry weights. In contrast, T2 (soil + coarse sand+ saw dust + FYM) and T10 (soil + coarse sand+ poultry manure+ FYM) exhibited no germination while T11 (forest soil + rice husk + wheat husk + poultry manure) resulted in minimal plant growth and mass production. The results of this study not only illuminate the most effective potting mixtures for successful marigold cultivation but also emphasize the significance of utilizing organic waste to promote sustainability and minimize environmental repercussions within the horticulture. Furthermore, they provide valuable guidance to gardeners, farmers, and marigold enthusiasts, demonstrating the potential for sustainable practices benefiting both plant growth and environmental well-being. Subsequent research can delve into additional potting mixtures and environmental variables, advancing marigold cultivation practices and contributing to sustainable agriculture and environmental preservation. A comprehensive understanding of potting mixtures' influence in early plant development can lead to improved marigold germination, waste reduction, and a more ecologically conscious approach to horticulture, ultimately enhancing marigold production.
