Pengaruh Pemberian Kompos Jerami dan Pupuk Sp-36 pada Tanah Sulfat Masam Potensial terhadap Perubahan Sifat Kimia Serta Pertumbuhan dan Produksi Padi (Oriza Sativa L.)
The objective of this research was to study the effect of rice straw compost and the application ofphosphorus fertilizer of SP-36 on chemical characteristic of acid sulphate soils, rice growth andproduction (Oryza sativa L). This research was conducted in greenhouse agricultural departments,Universities Northen Sumatera, Medan. This study used a randomized block design factorial, with2 factors : factor 1 : rice straw compost treatment (J) wich consist of : J0 = 0 ton ha-1(0 g straw/pot); J1 = 10 ton ha-1 (40 g straw/pot); J2 = 20 ton ha-1 (80 g straw /pot); J3 = 30 ton ha-1(120 g straw/pot). Faktor 2 : fertilizer phosphorus (P) which consist of : P0 = 0 kg SP-36 ha-1(0 g SP-36/pot); P1 = 0.5 dose (0.5 x 135 kg/ha), advice equal with 0,27 g SP-36/pot;P2 = 1,0 dose (1 x 135 kg/ha), advice equal with 0,54 g SP-36/pot; P3 = 1.5 dose (1.5 x 135 kg/ha),advice equal with 0,81 g SP-36/pot. This results of the research showed that rice straw composttreatment significantly affected C-organic, Fe2+ reduction, the maximum seedlings, dry weight ofroot. While the application of SP-36 fertilizer significantly affected the maximum seedlings.Combination of rice straw compost and fertilizer SP-36 significantly increased the maximumseedlings.
