ABSTRAK. Penelitian dilaksanakan di Kebun Percobaan Balai Penelitian Tanaman Sayuran Lembang (1.250 mdpl.) dengan jenis tanah Andisol, dari bulan Juni 2004-Januari 2005. Tujuan percobaan adalah mengetahui pengaruhpemberian zeolit, jenis pupuk kandang, dan dosis NPK terhadap kesuburan tanah dan hasil cabai merah varietas Tanjung1. Rancangan percobaan yang digunakan yaitu acak kelompok faktorial dengan tiga ulangan. Perlakuan terdiri ataspemberian zeolit (0 dan 500 kg/ha), jenis pupuk kandang (kuda, sapi, dan ayam) masing-masing 20 t/ha, dan dosis NPK15-15-15 (250, 500, 750, dan 1.000 kg/ha). Hasil penelitian menunjukkan bahwa tidak ada interaksi antara perlakuanzeolit, jenis pupuk kandang, dan dosis NPK 15-15-15 terhadap pertumbuhan dan hasil cabai merah. Pemberian zeolit500 kg/ha tidak berpengaruh terhadap sifat fisik, kimia, dan biologi tanah, begitu pula terhadap pertumbuhan danhasil cabai. Jenis pupuk kandang yang berbeda pada tingkat dosis yang sama (20 t/ha) tidak berpengaruh terhadappertumbuhan dan hasil cabai. Jenis pupuk kandang yang paling baik untuk pertumbuhan dan hasil cabai merah adalahpupuk kandang ayam. Pengurangan dosis pupuk NPK 15-15-15 dari 1.000 kg/ha menjadi 250 kg/ha tidak menurunkanhasil cabai merah secara nyata. Pemberian pupuk kandang perlu diberikan setiap kali bertanam, tetapi pupuk NPKtidak perlu diberikan secara berlebihan, agar produktivitas lahan dapat dipertahankan.ABSTRACT. Sumarni, N., R. Rosliani, and A.S. Duriat. 2010. Physical, Chemical, and Biological SoilManagement to Increase Soil Fertility and Hot Pepper Yield. The experiment was conducted at the ExperimentalGarden of Indonesian Vegetable Research Institute-Lembang (1,250 m asl.) on Andisol soil type from June 2004 upto January 2005. The aim of the experiment was to determine the effect of zeolite, stable manure, and NPK fertilizerapplications on soil fertility and hot pepper cv. Tanjung 1 yield. The treatments were set up in a factorial randomizedblock design with three replications. The treatments consisted of three factors, viz. (1) zeolite (0 and 500 kg/ha), (2)kinds of stable manure (horse, cow, and chicken manures) 20 t/ha respectively, and (3) NPK 15-15-15 (250, 500,750, and 1,000 kg/ha). The results indicated that there were no interaction effects between zeolite, stable manure, andNPK 15-15-15 on the growth and yield of hot pepper. Application of zeolite 500 kg/ha did not significantly affect thephysical, chemical, and biological characteristics of soil. It also did not affect on the growth and yield of hot pepper.The physical, chemical, and biological conditions of soil were not affected by the kinds of stable manure. But chickenmanure application gave the highest yield of hot pepper. Decreasing of NPK 15-15-15 dosages from 1,000 to 250 kg/ha did not significantly affect on the yield of hot pepper. Applying of stable manure (organic fertilizer) and adequatedosage of NPK fertilizer was necessary for each planting season to maintain the soil productivity
