Pengaruh kombinasi perlakuan pupuk kompos dan pupuk npk terhadap pertumbuhan dan hasil jagung manis (zea mays) pada inceptisol effect of combination treatment compost fertilizer and npk fertilizer on the growth and results sweet corn (zea mays) in inceptisol 1yusdi saputra, 2sufardi, 2yadi jufri 1)the alumni of agrotechnology departement of agriculture faculty of syiah kuala university, 2)lecturer in agrotechnology departement of agriculture faculty of syiah kuala university corresponding author: yusdisaputre@gmail.com abstrak research was conducted at the experimental garden of the faculty of agriculture unsyiah and soil analysis carried out in the laboratory of soil chemistry, faculty of agriculture unsyiah darussalam, banda aceh. the purpose of this study was to determine the effect of combined treatment of compost and npk fertilizer on soil chemical properties and see the growth and yield of corn. the method used in this study using a randomized block design (rak) single factorial consisting of 12 combined treatment with 3 replications. the parameters observed in this study include chemical properties of soil ph h2o, organic-c (%), n-total (%), p-available (%), k-dd (%). the growth observed of plant height and stem size is 2, 4, 6 weeks after planting (mst), while the yield components cob length, cob size, cob weight with skin, and cob without husk. the results showed that the combined treatment of compost and npk fertilizer effect on soil chemical properties, namely increasing ph h2o, organic c, k-dd, but has no effect on n-total. combination treatment of compost and npk significant effect on plant height, aged 4 and 6 mst but did not significantly affect plant height age 2 mst. compost and npk treatment combination that gives the best effect on the chemical properties of soil and yield of sweet corn obtained on peralakuan combination of compost and npk in treatment l = (60 ton ha-1 + npk 1500 kg ha-1). the results of corn weighs 152.26 grams. keywords: combination, compost, npk inceptisol
