One strategy for achieving sustainable agriculture is the reduction of inorganic fertilizers. Inorganic fertilizers are reduced by substituting them with organic fertilizers. This study aimed to identify the optimal combination of LOF with NPK fertilizers to promote the growth of cocoa seedlings in polybags. The study used completely randomized design. The treatment design, namely the combination of LOF with NPK fertilizers, consisted of five distinct combinations: control, 100% LOF, 100% NPK, 75% LOF 25% NPK, 50% LOF 50% NPK, and 25% LOF 75% NPK. The parameters observed were plant height, stem diameter, number of leaves, total leaf area, plant dry weight, shoot dry weight, root dry weight, soil physical properties, soil water content, soil analysis, and seedling quality index. The results showed that treatment 25% LOF 75% NPK increased the percentage of plant height by 73.47%, stem diameter by 42.13%, number of leaves by 67.36%, total leaf area by 75.30%, plant dry weight by 45.70%, shoot dry weight by 24.81%, root dry weight by 95.54%, and seedling quality index by 90.65%. LOF can reduce the use of NPK fertilizer by 25% in cocoa seedling.

The combination treatment of LOF with NPK fertilizer significantly affects plant height, stem diameter, number of leaves, total leaf area, plant dry weight, shoot dry weight, root dry weight, and seedling quality index.The 25% LOF 75% NPK treatment showed the highest average value for the observed parameters, increasing plant height by 73.13%, and seedling quality index by 90.Liquid organic fertilizer can reduce the use of NPK fertilizer by 25% in cocoa nurseries.

Penelitian lebih lanjut perlu dilakukan untuk menguji efektivitas kombinasi LOF dan NPK pada berbagai varietas kakao, karena respons pertumbuhan dapat bervariasi antar genotipe. Studi jangka panjang diperlukan untuk mengevaluasi dampak kombinasi pupuk ini terhadap kualitas buah kakao, seperti ukuran biji, kadar lemak, dan rasa. Selain itu, penelitian perlu dilakukan untuk mengoptimalkan dosis dan frekuensi aplikasi LOF dan NPK, dengan mempertimbangkan jenis tanah dan kondisi iklim setempat, untuk mencapai efisiensi penggunaan pupuk yang maksimal dan meminimalkan dampak lingkungan. Investigasi lebih lanjut mengenai mekanisme interaksi antara LOF dan NPK dalam meningkatkan pertumbuhan kakao, termasuk analisis perubahan mikrobioma tanah dan ekspresi gen terkait penyerapan nutrisi, dapat memberikan pemahaman yang lebih mendalam tentang manfaat kombinasi pupuk ini.
