Abstract
ABSTRAK
Tujuan penelitian ini adalah untuk mengetahui pengaruh pemupukan KCl dan kompos jerami terhadap pertumbuhan dan hasil padi sawah (Oryza sativa L.). Penelitian ini menggunakan rancangan acak kelompok (RAK) pola faktorial dengan 3 kali ulangan. Faktor pertama pupuk KCl (0, 100, 150 kg ha-1). Faktor kedua takaran kompos jerami (0, 10, 20 ton ha-1). Hasil penelitian menunjukkan bahwa pemberian pupuk KCl berpengaruh nyata terhadap tinggi tanaman umur 35 HST, jumlah anakan umur 25 HST, jumlah malai per rumpun, jumlah gabah isi per malai, persentase gabah hampa per malai, bobot 1000 butir gabah dan hasil gabah per hektar. Pemberian kompos jerami memberikan pengaruh nyata terhadap jumlah anakan umur 35 HST, jumlah malai per rumpun, jumlah gabah isi per malai, persentase gabah hampa per malai, bobot 1000 butir gabah dan hasil gabah per hektar. Pengaruh interaksi antara pemupukan KCl dan kompos jerami memberikan pengaruh nyata terhadap pH tanah, K tersedia dan bobot 1000 butir gabah. Kombinasi perlakuan terbaik pada pelakuan pupuk KCl 100 kg ha-1 dengan kompos jerami 20 ton ha-1.
ABSTRACT
The research is objective was to study effects of KCl fertilization and straw compost on growth and yield of rice plants. This studyplace from November 2010 to April 2011. Experiment was arranged in a randomized complete block design in a factorial design with three replications. The main factor a three standard of KCl fertilization: without KCl, 100 Kg ha-1 and 150 Kg ha-1. The second factor a three of straw compost without straw compost, 10 ton ha-1 and 20 ton ha-1. The results showed that the using KCl fertilizer significantly affected on plant height age 35 days after transplanting, number of tillers age 25 after days transplanting, number of panicles per hill, number of grains per panicle contents, percentage of empty grains perpanicle, weight of 1000 grains and grain yield per hectare. The provision of straw compost had a real effect on C-organic , N Total, K available and KTK soil, number of tillers age 35 days after transplanting, number of panicles per hill, number of grains per panicle contents, percentage of empty grains perpanicle, weight of 1000 grains and grain yield per hectare. The interaction between KCl fertilization and rice straw compost resulted highly significant on weight of 1000 grains. The best treatment combination was KCl fertilizer 100 Kg ha-1 with straw compost 20 ton ha-1.
