Abstract

Penelitian ini bertujuan untuk mempelajari pengaruh residu kompos dan aplikasi kompos campuran batuan fosfat, kotoran sapi dan jerami padi serta pemberian pupuk buatan terhadap pH, P-tersedia Ultisol serta hasil tanaman kacang tanah. Penelitian ini dilakukan dengan menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari 8 perlakuan yaitu: k0 = tanpa perlakuan, k1 = pupuk buatan rekomendasi, k2 = residu kompos 5 ton ha-1 + kompos 2,5 ton ha-1, k3 = residu kompos 5 ton ha-1 + ½ pupuk buatan rekomendasi, k4 = residu kompos 10 ton ha-1 + kompos 5 ton ha-1, k5 = residu kompos 10 ton ha-1 + ½ pupuk buatan rekomendasi, k6 = residu kompos 15 ton ha-1 + kompos 10 ton ha-1, k7 = residu kompos 15 ton ha-1 + ½ pupuk buatan rekomendasi. Variabel yang diamati adalah pH Tanah dan P-tersedia, tinggi tanaman, berat polong basah dan berat polong kering. Hasil penelitian menunjukkan bahwa residu kompos dan pemberian kompos campuran kotoran sapi, jerami padi, dan fosfat alam serta pupuk buatan dengan residu kompos + aplikasi kompos dan residu kompos + 1/2 rekomedasi pupuk buatan belum dapat memperbaiki pH tanah namun memperbaiki P-tersedia dan residu kompos 10 ton/ha + aplikasi 5 ton/ha kompos dapat menghasilkan berat polong kering 4.37 ton/ha yang lebih baik dari perlakuan lainnya. This study aims to study the effect of compost residues and the application of a mixture of rock phosphate, cow dung and rice straw compost and the application of artificial fertilizers on pH, available P-Ultisols and peanut crop yields. This research was conducted using a randomized block design (RBD) which consisted of 8 treatments: k0 = no treatment, k1 = recommended artificial fertilizer, k2 = compost residue 5 tons ha-1 + compost 2.5 tons ha-1, k3 = compost residue 5 tons ha-1 + ½ artificial fertilizer recommendation, k4 = compost residue 10 tons ha-1 + compost 5 tons ha-1, k5 = compost residue 10 tons ha-1 + ½ artificial fertilizer recommendation, k6 = compost residue 15 ton ha-1 + compost 10 ton ha-1, k7 = compost residue 15 ton ha-1 + ½ recommended artificial fertilizer. The variables observed were soil pH and available P, plant height, wet pod weight and dry pod weight. The results showed that compost residue and application of compost mixed with cow dung, rice straw, and natural phosphate and artificial fertilizers with compost residue + application of compost and compost residue + 1/2 of the recommended artificial fertilizer could not improve soil pH but improved available P and residue. compost 10 ton/ha + application of 5 ton/ha compost can produce dry pod weight 4.37 ton/ha which is better than other treatments.
