A’isyah, Siti (2019) Evaluasi Penambahan Zeolit dan Asam Humat untuk Meningkatkan Mikorisasi Akar dan Pertumbuhan Sorgum (Sorghum bicolor L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Penggunaan lahan marginal untuk tujuan pertanian membutuhkan upaya khusus agar dapat meningkatkan produksi tanaman pertanian. Keterbatasan sifat fisik, kimia, dan biologis tanah dari daerah ini harus diikuti dengan pengelolaan lahan yang tepat dan pemilihan teknologi yang sesuai. Hal ini dapat dicapai dengan penerapan teknologi pupuk biologis yang mengandung mikoriza dan pembenah tanah seperti zeolit dan asam humat. Tujuan dari penelitian ini adalah untuk mengevaluasi peran zeolit dan asam humat dalam meningkatkan infeksi akar oleh mikoriza dan peningkatan penyerapan fosfat (P) serta kalium (K) ke tanaman. Selain itu pertumbuhan tanaman, biomassa sorgum dan kadar gula sorgum dicatat dan akan dikorelasikan dengan infeksi akar oleh mikoriza. Penelitian dilakukan di laboratorium LIPI Cibinong dan Kebun Raya Bogor pada bulan November 2018-Maret 2019. Penelitian menggunakan Rancangan Acak Lengkap Faktorial dengan mikoriza sebagai faktor pertama dan soil conditioner sebagai faktor kedua sebanyak 3 ulangan. Kombinasi perlakuan antara lain DZ (tanah berdebu + zeolit 80 ton ha-1); PZ (tanah berpasir + zeolit 80 ton ha-1); DH (tanah berdebu + asam humat 450 ppm); PH (tanah berpasir + asam humat 450 ppm); DZH (tanah berdebu + zeolit 80 ton ha-1 + asam humat 450 ppm); PZH (tanah berpasir + zeolit 80 ton ha-1 + asam humat 450 ppm); MD (mikoriza + tanah berdebu); MP (mikoriza + tanah berpasir); MDZ (mikoriza + tanah berdebu + zeolit 80 ton ha-1); MPZ (mikoriza + tanah berpasir + zeolit 80 ton ha-1); MDH (mikoriza + tanah berdebu + asam humat 450 ppm); MPH (mikoriza + tanah berpasir + zeolit 80 ton ha-1); MDZH (mikoriza + tanah berdebu + zeolit 80 ton ha-1 + asam humat 450 ppm); MPZH (mikoriza + tanah berpasir + zeolit 80 ton ha-1 + asam humat 450 ppm). Parameter yang diamati meliputi total infeksi akar per tanaman, ketersediaan P-total dan K-total, serapan P dan K, C-organik, kadar gula, tinggi tanaman, jumlah daun, dan berat biomassa Sorgum. Analisa data menggunakan Analysis of Variance (ANOVA) menggunakan program pengolah data Genstat Discovery dengan uji lanjut Fisher’s 5%. Perlakuan soil conditioner zeolit 80 ton ha-1 dan asam humat 450 ppm memberikan nilai tertinggi terhadap infeksi akar dan kadar gula pada 8 MST, yang secara significant berbeda dengan perlakuan yang lainnya (P<0.05). Perlakuan MPZH memberikan hasil infeksi akar tertinggi dan P-total dan K-total tanah. Nilai tertinggi pada parameter tinggi tanaman dan berat biomassa sorgum ditemukan pada perlakuan MD, sedangkan jumlah daun tertinggi ditunjukkan oleh perlakuan MP. Perlakuan PZ memberikan nilai tertinggi terhadap serapan K 12 MST dan persentase kadar gula 12 MST. Perlakuan kombinasi mikoriza + zeolit pada tanah berpasir (MPZ) memberikan nilai tertinggi terhadap hasil serapan P tanaman pada 8 dan 12 MST. Nilai C-organik tertinggi ditemukan pada perlakuan MDZ. Nilai tertinggi serapan K tanaman 8 MST dijumpai pada perlakuan MPH.
English Abstract
The use of marginal land for agricultural purposes require efforts to increase agricultural crop production. Limitations of physical, chemical and biological soil properties of this area must be incorporating by proper land management and selecting appropriate technology. This can be achieved by the application of biological fertilizers containing mycorhizae and soil conditioner such as zeolite and humic acid. The aim of this research was to evaluate the role of zeolite and humic acid in increasing root infection by mycorrhizal and evaluate how to extend the increasing on the uptake of phospate (P) dan potassium (K) of sorghum. In addition plant growth, biomass and sugar content of sorghum were recorded and it will be correlated with those root infection. The research was conducted in LIPI Cibinong and Bogor Botanical Garden Laboratory in November 2018-March 2019. The research used a Factorial Complete Randomized Design with 2 factor which are mycorrhizal and soil conditioners with 3 replicates. The combinations of treatments were as follow : DZ (silty soil + zeolite 80 tons ha-1); PZ (sandy soil + zeolite 80 tons ha-1); DH (silty soil + humic acid 450 ppm); PH (sandy soil + humic acid 450 ppm); DZH (silty soil + zeolite 80 tons ha-1 + humic acid 450 ppm); PZH (sandy soil + zeolite 80 tons ha-1 + humic acid 450 ppm); MD (mycorrhiza + silty soil); MP (mycorrhiza + sandy soil); MDZ (mycorrhiza + silty soil + zeolite 80 tons ha-1); MPZ (mycorrhiza + sandy soil + zeolite 80 tons ha-1); MDH (mycorrhiza + silty soil + humic acid 450 ppm); MPH (mycorrhiza + sandy soil + zeolite 80 tons ha-1); MDZH (mycorrhiza + silty soil + zeolite 80 tons ha-1+ humic acid 450 ppm); MPZH (mycorrhiza + sandy soil + zeolite 80 tons ha-1+ humic acid 450 ppm). The parameters which were measure: number of root infection, P-total and K-total, uptake of P and K, organic carbon, sugar content, plant height, number of leaves and weight of sorghum biomass. Data analysis used Analysis of Variance (ANOVA) in Genstat Discovery. The significant different of the treatments were processing with Fisher's test (5%). The treatment of zeolite at 80 tons ha-1 and humic acid 450 ppm had the greatest value on root infection and sugar content at 8 WAP which was significantly different to other treatments (P<0,05). The treatment of MPZH showed the highest root infection and had a significant effect on total-P and total-K. In addition, MD treatment significantly affects to the crop growth, particularly on plant height and biomass weight of sorghum, meanwhile the greatest number of leaves were detected in MP treatment. The PZ treatment significantly affected the uptake of potassium (K) on 12 week after planting (WAP) and the percentage of sugar content of Sorghum on 12 WAP. The combination treatment of mycorrhiza and zeolite in sandy soil (MPZ) has a greatest value and giving a significant effect to P uptake at 8 and 12 WAP. Moreover, MDZ treatments were significantly affecting C-organic and MPH treatment was significantly impacted to the absorption and had the greatest of K uptake on Sorghum at 8 WAP.
