Adiningrum, Tanti Dwi (2019) Pengaruh Vermikompos terhadap Pertumbuhan Tebu (Saccharum officinarum) pada Berbagai Kadar Garam Tanah. Sarjana thesis, Universitas Brawijaya.
Abstract
Perluasan lahan untuk penanaman tebu, beralih ke lahan marginal, karena lahan yang subur digunakan untuk budidaya tanaman pangan. Lahan marginal salah satunya adalah lahan salin. Kandungan kadar garam yang tinggi pada lahan salin berpengaruh terhadap kadar hara dan pertumbuhan tanaman tebu. Untuk mengurangi kadar salinitas tanah, maka diberikan penambahan vermikompos dengan masing-masing dosis yang berbeda. Vermikompos dianggap sebagai pupuk organik yang memiliki banyak kandungan unsur hara penting bagi tanah dan tanaman. Tujuan penelitian ini yaitu untuk mengetahui pengaruh vermikompos terhadap pertumbuhan tebu (Saccharum officinarum) pada berbagai kadar garam tanah. Penelitian ini dilaksanakan pada bulan Oktober 2018 hingga Maret 2019 di Balai Penelitian Tanaman Pemanis dan Serat (BALITTAS) Malang. Analisis sampel tanah dan analisis pertumbuhan tanaman tebu dilaksanakan di Laboratorium Kimia Tanah Fakultas Pertanian Universitas Brawijaya. Penelitian menggunakan Rancangan Acak Kelompok (RAK). Rancangan Acak Kelompok digunakan, untuk melihat pengaruh dari perlakuan vermikompos dan asal tanah dengan berbagai kadar garam berbeda dari 3 lokasi. Lokasi pertama Tuban di Desa Cepokorejo, Kecamatan Palang, Kabupaten Tuban, lokasi kedua Lamongan di Desa Sidomukti, Kecamatan Brondong, Kabupaten Lamongan. Lokasi ketiga Bojonegoro di Desa Pasinan, Kecamatan Baureno, Kabupaten Bojonegoro. Vermikompos diberikan dengan dosis kontrol, 300 g/pot dan 600 g/pot. Parameter yang diamati yaitu tanah, kadar di daun dan pertumbuhan tanaman. Hasil penelitian menunjukkan bahwa penambahan vermikompos pada tanah dengan berbagai kadar garam berpengaruh nyata. Kadar garam dengan EC tinggi (Tuban) dan penambahan vermikompos tidak berpengaruh nyata pada nilai EC tanah, Na-dd tanah, dan kadar Na daun tebu. Nilai EC tertinggi perlakuan kontrol saat 1,2,3 dan 4 BST berturut-turut 11,23 dS/m; 10,23 dS/m; 9,06 dS/m dan 7,60 dS/m. Kemudian Na-dd tanah tertinggi perlakuan kontrol yaitu 9,07 me/100g, kadar Na daun tertinggi perlakuan kontrol yaitu 0,33 %. Pada perlakuan kadar garam tanah dengan EC lebih rendah dari Tuban yaitu (Lamongan) vermikompos berpengaruh terhadap K tersedia tanah, kadar K daun dan rasio K/Na. Nilai K tersedia tanah tertinggi pada perlakuan vermikompos 600 g/pot yaitu 1,50 me/100g. Nilai kadar K daun tebu tertinggi perlakuan vermikompos 600 g/pot yaitu 1,77 %. Nilai rasio K/Na tertinggi pada perlakuan vermikompos 600 g/pot yaitu 6,00 me/100g yaitu 1,50 me/100g, dan berpengaruh terhadap kadar K di daun. Sedangakan tanah dengan EC rendah (Bojonegoro) penambahan vermikompos berpengaruh positif terhadap pH tanah, EC tanah, C-organik tanah, N total tanah, dan kadar N di daun. Nilai pH tanah terendah pada perlakuan vermikompos 0 g/pot yaitu 5,48 dengan kriteria agak masam. Nilai EC tanah terendah pada perlakuan vermikompos 600 g/pot umur 1,2,3 dan 4 BST berturut- turut 0,68 dS/m; 0,55 dS/m; 0,20 dS/m; dan 0,17 dS/m. Nilai C-organik tertinggi pada perlakuan vermikompos 600 g/pot yaitu 4,69 %, dan nilai N total tanah tertinggi pada perlakuan vermikompos 600 g/pot yaitu 0,38 %,sedangkan nilai kadar N daun tertinggi pada perlakuan vermikompos 600 g/potyaitu 2,62 % dan berpengaruh nyata terhadap pertumbuhan tanaman dari semua parameter pengamatan.
English Abstract
Since fertile land is used for food crop cultivation land expansion for sugar cane cultivation, is divertedto marginal land. because. Marginal land is one of the saline land. The high salt content in saline land influences nutrient uptake and sugar cane growth. To reduce the soil salinity, a vermicompost application was given with each different dose. Vermicompost is considered as an organic fertilizer that has many important nutrients for soil and plants. The purpose of this study was to determine the response of sugarcane growth and nutrient uptake of sugarcane (Saccharum officinarum) to the response of various doses of vermicompost to saline soils. This research was conducted in October 2018 to March 2019 at the Research Institute for Sweeteners and Fiber Plants (BALITTAS) Malang. Analysis of soil samples and analysis of sugarcane plant growth were carried out at the Soil Chemical Laboratory, Faculty of Agriculture, Brawijaya University. The study used a randomized block design (RBD). Randomized Block Design was used, to probe the effect of vermicompost treatment and soil origin with different salinity from 3 locations. The first location was Tuban, it was in Cepokorejo Village, Palang District, Tuban Regency, the second location was Lamongan, it was in Sidomukti Village, Brondong District, Lamongan Regency. The third location was Bojonegoro, it was in Pasinan Village, Baureno District, Bojonegoro Regency. Vermicompost was given at a dose control, 300 g/pot and 600 g/pot. The parameters observed were soil, leaf content and plant growth. The results showed that the addition of vermicompost to soils with various salinity had a significant effect. Salt content with high EC (Tuban) and the addition of vermicompost had no significant effect on soil EC values, soil Na-dd, and Na levels of sugarcane leaves. The highest EC values of the control treatments at 1,2,3 and 4 BST were 11.23 dS/m; 10.23 dS/m; 9.06 dS/m and 7.60 dS/m respectively. Moreover, the highest Na-dd of the control treatment was 9.07 me/100g, the highest Na content of the control treatment was 0.33%. In the treatment of soil salinity with EC lower than soil salinity Tuban in (Lamongan), vermicompost affected the available K soil, leaf K content and the K/Na ratio. The highest K value of available soil in the 600 g / pot vermicompost treatment was 1.50 me/100g. The highest K content of sugarcane leaves was 600 g/ pot vermicompost treatment at 1.77%. The highest K/ Na ratio value in vermicompost treatment of 600 g/pot was is 1.50 me/100g, and it influenced the K content in leaves. While in the soil with low EC soil salinity (Bojonegoro),the addition of vermicompost had a positive effect on soil pH, soil EC, soil C-organic, total soil N, and leaf N content. The lowest soil pH value in the treatment of vermicompost of control was 5.48 with slightly acid criteria. The lowest soil EC value in the treatment of vermicompost 600 g/pot is 1,2,3 and 4 BST ; 0,68 dS/m; 0.55 dS/m; 0.20 dS/m; and 0.17 dS/m respectively. The highest C-organic value for iii vermicompost treatment of 600 g/pot, was 4.69%, and the highest total N value for vermicompost treatment of 600 g/pot, was 0.38%, while the highest N leaf content value for vermicompost treatment of 600 g/pot. was 2.62% and it significantly affected plant growth from all observations parameters.
