- REKAYASA PENINGKATAN PRODUKSI KEDELAI DENGAN FORMULA PUPUK ORGANIK SAMPAH KOTA DAN DOLOMIT PADA LAHAN MARJINAL Oleh : Astiningrum. M, Haryono G, Historiawati ABSTRAK This research aims to find out “REKAYASA PENINGKATAN PRODUKSI KEDELAI DENGAN FORMULA PUPUK ORGANIK SAMPAH KOTA DAN DOLOMIT PADA LAHAN MARJINAL” in Keburuan, Ketawangrejo Village, Grabag District, Purworejo Regency, soil types Regosol, the altitude is 6 meter above sea level with pH 0,5, which so far has low crop productivity with average soybean production 1,5 ton/ha. The research conducted in the field using factorial design that was arranged in a complete randomized block design with two-factor treatment and was repeated three times. Factor 1. Shisako organic fertilizer dose (S) : 0 ; 2,5 ; 5 ton/ha. Factor 2. Dolomite Dose (D) : 0 ; 1 ; 2 ton/ha. Production data and protein content that was gotten then was analyzed by analysis of variance, if there is a significant difference then will be continued by orthogonal polynomial test to find out what the actual optimal close is, either for organic fertilizer and dolomite or its combination.
