RESPON PERTUMBUHAN DAN HASIL TANAMAN KACANG TANAH AKIBAT PEMBERIAN KOMPOS DAN PUPUK FOSFAT

This study aimed to determine the response to growth and yield of peanuts due to the application of compost and phosphate fertilizer then the interaction between those two factors. The research had done in Dusun Blang Phon Gampong Saree Aceh, Kecamatan Lembah Seulawah, Kabupaten Aceh Besar. There used in 4 x 3 factorial with 3 replications by Group Randomized Design (GRD). The first factor was compost dose (K) dose (levels: K0 = 0 tons/ha, K1 = 5 tons/ha, K2 = 10 tons/ha, K3 = 15 tons/ha) and the second factors was phosphate fertilizer ( P) (levels: P1 = 50 kg/ha, P2 = 100 kg/ha, P3 = 150 kg/ha). The results had compost fertilizer dose had a very significant effect on height plant at 15 and 45 the day after planting. The number of filled pods per plant, weight dry pod weight per net plot, and weight dry seed per plant had significantly affected height plant at 30 the day after planting. Then, the phosphate fertilizer dose had a very significant effect on the number of filled pods per clump, weight dry pod per net plot, and weight dry seed per net plot, but had not significant effect on height plant at 15, 30, and 45 days after planting. The research was a very significant interaction between compost a phosphate fertilizers on weight dry pods per net plot and weight dry seed of peanuts per plant. Then there was a significant interaction with the number of filled pods per plant.Penelitian ini bertujuan untuk mengetahui respon pertumbuhan dan hasil tanaman kacang tanah akibat pemberian kompos dan pupuk fosfat serta interaksi antara kedua faktor tersebut, dilaksanakan di dusun Blang Phon Gampong Saree Aceh, Kecamatan Lembah Seulawah, Kabupaten Aceh Besar. Rancangan yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok (RAK) pola faktorial 4 x 3 dengan 3 ulangan. Ada dua faktor yang diteliti yaitu: dosis kompos (K) terdiri dari empat taraf perlakuan : K0 = 0 ton/ha, K1 = 5 ton/ha, K2 = 10 ton/ha, K3 = 15 ton/ha dan dosis pupuk fosfat (P) terdiri dari tiga taraf perlakuan : P1 = 50 kg/ha, P2 = 100 kg/ha, P3 = 150 kg/ha. Hasil penelitian menunjukkan bahwa dosis kompos berpengaruh sangat nyata terhadap tinggi tanaman pada umur 15 dan 45 hst, jumlah polong berisi per tanaman, berat polong kering per plot netto, dan berat biji kering per tanaman, serta berpengaruh nyata terhadap tinggi tanaman pada 30 hst. Dosis pupuk fosfat berpengaruh sangat nyata terhadap jumlah polong berisi per rumpun, berat polong kering per plot netto, dan berat biji kering per plot netto, namun berpengaruh tidak nyata terhadap tinggi tanaman umur 15, 30, dan 45 hst. Terdapat interaksi yang sangat nyata antara perlakuan dosis kompos dan dosis pupuk fosfat terhadap berat polong kering per plot netto dan berat biji kering kacang tanah per tanaman, dan terdapat interaksi yang nyata terhadap jumlah polong berisi per tanaman
