GanarPriambodo (2016) Efek Residu Aplikasi Asam Humat Dan Sp 36 Terhadap Sifat Kimia Tanah Dan Pertumbuhan Jagung Manis (Zea Mays Saccharata Sturt) Pada Inceptisol, Dau Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Inceptisol mempunyai prospek cukup besar untuk dikembangkan sebagai sentra produksi tanaman pangan terutama padi, jagung, dan kedelai apabila pengelolaan tanah dan tanaman tepat. Kendala pada Inceptisol yaitu pH masam, rendahnya C-Organik, N total dan K tersedia. Rendahnya bahan organik dalam Inceptisol dapat ditingkatkan dengan beberapa cara, diantaranya aplikasi pupuk asam humat dan pupuk anorganik. Asam humat salah satu bahan yang dapat meningkatkan pertumbuhan dan hasil produksi tanaman serta dapat meningkatkan kesuburan tanah dan ketersediaan unsur hara. Hal tersebut disebabkan asam humat mempunyai sifat slow release, oleh karena itu aplikasi asam humat pada pertanaman pertama diharapkan masih dapat memberikan pengaruh terhadap sifat kimia tanah dan pertumbuhan jagung manis muda pertanaman kedua. Tujuan penelitian ini yaitu untuk mengetahui pengaruh residu aplikasi asam humat pada beberapa konsentrasi dan SP36 terhadap sifat kimia tanah, serapan P dan pertumbuhan jagung manis (Zea mays saccharata sturt) Penelitian dilaksanakan di screen house yang terletak di daerah Dau, Kabupaten Malang. Analisis kimia dilaksanakan di Laboratorium Kimia Jurusan Tanah Fakultas Pertanian Universitas Brawijaya Malang. Penelitian ini dilaksanakan dari bulan Desember 2015 sampai dengan Februari 2016. Penelitian ini menggunakan rancangan acak lengkap faktorial (RALF) pada residu penelitian Afrilia (2015) dengan 2 faktor. Faktor pertama adalah dosis aplikasi asam humat (A) yang digunakan terdiri dari empat taraf yaitu A0 = 0 ppm; A1 = 1000 ppm; A2 = 2000 ppm; A3 = 4000 ppm dan faktor yang kedua adalah takaran dosis SP36 (S) yang terdiri dari 3 taraf yaitu S1 = 50% dosis rekomendasi; S2 = 75% dosis rekomendasi; S3 = 100% dosis rekomendasi. Jumlah perlakuan (4x3) dan 3 ulangan, sehingga total keseluruhan terdapat 36 perlakuan. Aplikasi pupuk pada penelitian ini menggunakan pupuk Urea dengan dosis 300kg ha-1 dan pupuk KCl dengan dosis 150kg ha-1 Hasil penelitian menunjukkan bahwa residu aplikasi asam humat memberikan pengaruh nyata terhadap perbaikan sifat kimia tanah (pH dan P tersedia tanah) pada pertanaman kedua. Residu aplikasi asam humat juga mampu meningkatkan pertumbuhan tinggi tanaman dan jumlah daun tanaman jagung manis pada 8 MST namun P total tanaman dipengaruhi oleh residu SP36 dari pertanaman pertama
English Abstract
Inceptisol is highly prospective soil to be developed as a center for the production of food crops, especially on rice, corn, and soybeans if only the soil and plants manage properly. The obstacles in the Inceptisol soil are the acidic pH, the slight of C Organic, the availability of N and K total. Low organic substance in the Inceptisol could be improved with some application of humic acid fertilizer and inorganic fertilizer. Humic acid is one of the substance that could lead the improvement of the plant growth and production, soil fertility, and the enhancement of nutrient availability. This is due to the humic acid which has a slow release characteristic, therefore the application of humic acid on the first plantation is expected to be able to give the effect to the chemical properties of the soil and the growth of sweet corn in the second planting. The purpose of this study is to determine the effect of the application of humic acid residues at some concentration and SP36 towards the physical properties of the soil, the absorbtion of P and the growth of sweet corn (Zea Mays Saccharata Sturt). This research was conducted in a screen house which is located in Dau, Malang. Thus, the chemical analysis was conducted in Laboratory of Soil Chemistry, Faculty of Agriculture, Brawijaya University, Malang, on December 2015 until February 2016. In this study, the researcher used a Complete Randomized Design (CRD) factorial research Afrilia residue (2015) with two factors. The first factor is the dose application of humic acid (A) that has been used which consists of four levels i.e. A0 = 0 ppm; A1 = 1000 ppm; A2 = 2000 ppm; A3 = 4000 ppm and the second factor is the dose size of SP36 (S), which consists of three levels i.e. S1 = 50% dose recommendation; S2 = 75% dose recommendation; S3 = 100% in dose recommendation. The amount of the treatment in this study were (4x3) combinations of treatments and 3 repetitions, thus the overall total there are 36 treatments. In this study application of fertilizer using a dose of urea 300kg ha-1 and KCl fertilizer dose 150kg ha-1 The results of the research showed that the residual of humic acid applications gives significant effect on the changes of soil chemical properties (pH and P soil availability) in the second plantation.The residue of humic acid application is also able to increase the growth of plant height and the amount of sweet corn leaves at 8 weeks after planting but the P total of the plant influenced by the residues of SP36 on the first plantation.
