Abstract


Residue Effect of KCl Fertilizer and Rice Straw Compost in Soil Chemical Properties and Rice (Oryza sativa L.) Growth

Abstract: This research aims to study of the residue effect of KCl fertilizer and residue rice straw compost in the rendengan planting season on the chemical properties of soil and rice growth in the gadu planting season. This research was conducted by using randomized block design (RBD) factorial pattern which consists in two factors with three replications. The first factor is KCl fertilizer residues which consist: 0, 100 and 150 kg ha-1, the second factor is the residue of rice straw compost which consists of: 0, 10 and 20 ton ha-1. This research was conducted in Empetring Sub-district, Darul Kamal, Aceh Besar District. Further soil analysis was performed at the Soil Chemistry Laboratory, Agriculture Faculty, Syiah Kuala University, Banda Aceh. The results of research showed that KCl fertilizer residues provide a significant influence on the pH, available-P, exchangeable-K, organic-C, total-N, cation exchange capacity, but not significant effect on plant height that aged of 15, 30 and 45 Days after planting and number of seedlings aged 15, 30 and 45 days after planting. The provision of rice straw compost residual treatment gives a very significant influence on the pH, available-P, exchangeable-K, organic-C, total-N, cation exchange capacity and the real for the plant height that age 30 Days After Planting, but not significant effect on the exchange-K, plant height age of 15 and 45 days after planting and the number of seedlings age of 15, 30 and 45 days after planting. There is a very real interaction to the pH and the organic-C, but not significant effect on the pH to available-P, exchangeable-K, total-N, cation exchange capacity, plant height that age 15, 30 and 45 days after planting and seedlings that age 15, 30 and 45 days after planting.

Abstrak: Penelitian ini bertujuan untuk mengkaji pengaruh residu pupuk KCl dan residu kompos jerami padi musim tanam rendengan terhadap sifat kimia tanah dan pertumbuhan tanaman padi sawah musim tanam gadu. Penelitian ini menggunakan rancangan acak kelompok (RAK) pola faktorial yang terdiri dari dua faktor yaitu residu pupuk KCl dan residu kompos jerami padi. Penelitian telah berlangsung di Desa Empetring, Kecamatan Darul Kamal, Kabupaten Aceh Besar. Hasil penelitian menunjukkan bahwa residu pupuk KCl secara interaksi dengan residu kompos jerami padi berpengaruh sangat nyata terhadap pH dan C-organik tanah. Residu kompos dan KCL secara tunggal berpengaruh nyata terhadap N-total, dan P-tersedia, dan KTK tanah. Sedangkan residu KCl nyata pengaruhnya terhadap K-dd tanah, sedangkan residu kompos berpengaruh nyata terhadap pertumbuhan tanaman.
