Abstract

Pengolahan tanah yang intensif (pelumpuran) berdampak pada rusaknya struktur tanah. Hal ini ditandai dengan meningkatkan berat isi tanah, menurunnya porositas, meningkatkan kekuatan tanah saat pengeringan dan menurunnya daya jerap air, sehingga aerasi tanah menjadi kurang optimal. Oleh sebab itu perlu dilakukan perbaikan sifat fisiknya melalui pemberian zeolit dan kompos jerami padi. Tujuan penelitian adalah untuk mengetahui pengaruh pemberian zeolit, kompos jerami dan kombinasinya terhadap perbaikan sifat fisik tanah serta pertumbuhan dan produksi jagung. Pelaksanaan penelitian berlangsung mulai bulai Mei sampai dengan Agustus 2013 berlokasi di Kecamatan Purworejo, Pasuruan. Penelitian menggunakan rancangan acak kelompok RAK, terdiri dari 8 perlakuan 3 ulangan antara lain, P0 (Tanpa zeolit + kompos), P1 (Zeolit 30 ton ha-1), P2 (Kompos 5 ton ha-1), P3 (Kompos 10 ton ha-1), P4 (Kompos 15 ton ha-1), P5 (Zeolit 30 ton ha-1 + Kompos 5 ton ha-1), P6 (Zeolit 30 ton ha-1 + Kompos 10 ton ha-1) dan P7 (Zeolit 30 ton ha-1 + Kompos 15 ton ha-1). Kesimpulan yang dapat diambil berdasarkan hasil penelitian adalah belum terdapat pengaruh yang nyata dari pemberian perlakuan terhadap perbaikan sifat fisik tanah serta pertumbuhan dan produksi jagung. Hal ini dikarenakan pendeknya waktu penelitian atau aplikasi perlakuan. Mengingat sifat fisik tanah kurang sensitif terhadap pemberian perlakuan

English Abstract

Intensive tillage (puddling) impact on the destruction of the soil structure. It is characterized by increasing the bulk density, reduction of porosity, increase the soil strength when the ground while drying and decreased water absorbed, so the soil aeration being less than optimal. Therefore need to be repaired of soil physical in distributing zeolite and compost rice straw. The purposes of this study was to know the influence of the granting of a zeolite, compost rice straw and their combinations to repair the physical properties of land and growth and the production of corn. The research was conducted on May until August 2013 located in Sub-district Purworejo, Pasuruan. The experimental design used a Randomized Block Design, with 8 treatment 3 replication. The treatment were the application is, P0 (without zeolite + compost), P1 (zeolite 30 tons ha-1), P2 (compost 5 tons ha-1), P3 (compost 10 tons ha-1), P4 (compost 15 tons ha-1), P5 (zeolite 30 tons ha-1 compost + 5 tons ha-1), P6 (zeolite 30 tons ha-1 + compost 10 tons ha-1) and P7 (zeolite 30 tons ha-1 + compost 15 tons ha-1). The results of this research showed that non significant all of treatments to repair the soil physical properties, growth and production of maize. This is due to the shortness of time research or application treatment. Considering the physical properties of the soil less sensitive to granting preferential treatment so that it takes a relatively long time to be able to fix.
