The persistence of Phytophthora palmivora Butler in soil as mycelia and spores complicates its management. Composting, particularly with cocoa pod husks, enriches soil and suppresses plant diseases. Cocoa pod husk compost enhances seedling growth, improving plant height, dry matter, and foliar nitrogen. Cocoa pod husks also present a sustainable substratum for composting, as a substantial amount of it is left unused after bean harvesting. This study investigated the effects of cocoa pod husk-based compost and watering frequencies on PSBD suppression and cocoa seedling performance. Conducted in Prestea Nkwanta, Ghana, the experiment involved three factors: cocoa hybrid genotypes (PA150 and C85), compost ratios (soil alone, compost alone, 9 kg compost + 81 kg soil, and 18 kg compost + 72 kg soil), and watering frequencies (twice or thrice weekly). Disease incidence, growth, and root architecture parameters were analyzed using GenStat. Results showed significantly higher PSBD incidence in soil alone compared to compost-amended soils (p < 0.05). Growth parameters also varied significantly among treatments (p < 0.05). Cocoa pod husk compost significantly improved cocoa growth and suppressed PSBD, with reduced watering frequency enhancing effectiveness. cocoa pod husk compost cocoa seedling growth disease suppression root architecture soil amendment cocoa hybrid genotypes kompost iz plodov kakavovca rast sejank kakavovca zatiranje bolezni arhitektura korenin dodatki k prsti hibridni genotipi kakavovca true false true Angleški jezik Slovenski jezik Članek v reviji 2025-10-21 12:53:54 2025-10-21 12:54:01 2025-12-07 03:55:05 0000-00-00 00:00:00 2025 0 0 10 str. no. 3 Vol. 121 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2025.121.3.21676 254088963 https://journals.uni-lj.si/aas/article/view/21676/18907 1 f85e6a1e-ae6b-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220529 View_of_Effect_of_cocoa_pod_husk-based_compost_and_watering_frequencies_on_Phytophthora_seedling_blight_disease_suppression_and_seedling_growth_of_cocoa_clones.pdf View_of_Effect_of_cocoa_pod_husk-based_compost_and_watering_frequencies_on_Phytophthora_seedling_blight_disease_suppression_and_seedling_growth_of_cocoa_clones.pdf 1 27C16DA7F4BB86D17A3033E6DE6B4878 5e2431300b9989523b15ac6fabacdd632a9e960124a687e6ab1d1614590e02e5 1d0a8ea2-ae6c-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220530 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
