Abstract

Kebutuhan pangan meningkat seiring bertumbuhnya populasi penduduk, salah satunya adalah tomat (Solanum lycopersicum). Dibutuhkan produksi tanaman tomat dengan jumlah yang sesuai dengan jumlah permintaan pasar. Produksi yang meningkat sejalan dengan pertumbuhan dan kualitas tanaman yang baik serta didukung oleh kandungan unsur hara media tumbuh tanaman yang ketersediaannya mencukupi untuk pertumbuhan tanaman tomat. Upaya yang dapat dilakukan yaitu pemberian pupuk organik cair (POC) untuk mengurangi pemakaian pupuk anorganik dan untuk meningkatkan pertumbuhan tanaman tomat. Penerapan teknologi nano pada pupuk merupakan salah satu pengembangan teknologi pada sektor pertanian. Penelitian ini bertujuan untuk menganalisis pengaruh pupuk organik cair berteknologi nano terhadap populasi bakteri penambat nitrogen dan serapan N tanaman serta pertumbuhan tanaman tomat. Kegiatan penelitian ini dilaksanakan di Greenhouse yang terletak di Jalan Kraguman, Desa Tegalweru, Kecamatan Dau, Kabupaten Malang, Jawa Timur. Penelitian dilakukan pada bulan Juni hingga Oktober 2022. Kegiatan analisis sampel tanah dilakukan di Jurusan Tanah, Fakultas Pertanian, Universitas Brawijaya. Penelitian ini menggunakan rancangan acak lengkap (RAL), terdiri dari 5 perlakuan dan 4 ulangan. Perlakuan yang diterapkan meliputi : 1) Kontrol (P0); 2) Konvensional (P1); 3) POC 5 ml/10 kg tanah (P2); 4) POC 20 ml/10 kg tanah(P3); 5) POC 30 ml/10 kg tanah (P4). Parameter yang diamati meliputi jumlah populasi bakteri penambat N, sifat kimia tanah (pH tanah, C-organik, N total dan N tersedia) dan pertumbuhan tanaman (tinggi tanaman, jumlah daun, diameter batang dan serapan N tanaman). Keragamaan data parameter pengamatan diuji dengan ANOVA 5% perbedaan antar perlakuan diuji dengan Duncan Multiple Range Test (DMRT) taraf 5%, selanjutnya diuji korelasi antar parameter dan uji regresi. Analisis data dilakukan dengan menggunakan Microsoft Excel dan Software R. Hasil dari penelitian ini menunjukkan pemberian POC berteknologi nano diperkaya mikroba memberikan pengaruh nyata terhadap populasi bakteri penambat nitrogen, pH tanah, N total, N tersedia. Selain itu pengaplikasian POC berteknologi nano diperkaya mikroba berpengaruh nyata terhadap parameter pertumbuhan tanaman meliputi tinggi tanaman, jumlah daun, diameter batang serta serapan N tanaman. Terdapat hubungan yang kuat antara populasi bakteri penambat nitrogen dan amonium (r = 0.79) serta nitrat (r = 0.73), antara populasi bakteri penambat nitrogen dan serapan N tanaman tomat (r = 0.58), demikian pula didapatkan hubungan kuat antara populasi bakteri penambat nitrogen dan tinggi tanaman tomat (r = 0.62) . Terdapat pengaruh populasi bakteri penambat nitrogen terhadap amonium (R 2 = 0.62) serta nitrat (R 2 = 0.53), populasi bakteri penambat nitrogen terhadap serapan N tanaman (R 2 = 0,34), populasi bakteri penambat nitrogen terhadap tinggi tanaman tomat (R 2 = 0.38)

English Abstract

Food needs increase as the population grows, one of which is tomato (Solanum lycopersicum). It takes the production of tomato plants in an amount that matches the amount of market demand. Increased production is in line with good plant growth and quality and is supported by the nutrient content of the plant growth media which is sufficient for the growth of tomato plants. Efforts that can be made are the application of liquid organic fertilizer (POC) to reduce the use of inorganic fertilizers and to increase the growth of tomato plants. The application of nanotechnology to fertilizers is one of the technological developments in the agricultural sector. This study aims to analyze the effect of nano-technology liquid organic fertilizer on the population of nitrogen-fixing bacteria and plant N uptake and growth of tomato plants. This research activity was carried out at the Greenhouse located on Jalan Kraguman, Tegalweru Village, Dau District, Malang Regency, East Java. The research was conducted from June to October 2022. Soil sample analysis was carried out at the Soil Department, Faculty of Agriculture, Brawijaya University. This study used a completely randomized design (CRD), consisting of 5 treatments and 4 replications. The treatments applied include: 1) Control (P0); 2) Conventional (P1); 3) POC 5 ml/10 kg of soil (P2); 4) POC 20 ml/10 kg of soil (P3); 5) POC 30 ml/10 kg of soil (P4). Parameters observed included the number of populations of N-fixing bacteria, soil chemical properties (soil pH, C-organic, total N and available N) and plant growth (plant height, number of leaves, stem diameter and plant N uptake). The diversity of the observation parameter data was tested with 5% ANOVA, the differences between treatments were tested with the Duncan Multiple Range Test (DMRT) at 5% level and then the correlation between parameters was tested and the regression test. Data analysis was performed using Microsoft Excel and Software R. The results of this study showed that the application of POC enriched with nano-technology microbes had a significant effect on the population of nitrogenfixing bacteria, soil pH, total N, available N. In addition, the application of POC enriched with nano-technology microbes has a significant effect on plant growth parameters including plant height, number of leaves, stem diameter and plant N uptake. There was a strong relationship between the population of nitrogen-fixing bacteria and ammonium (r = 0.79) and nitrate (r = 0.73), between the population of nitrogen-fixing bacteria and N uptake of tomato plants (r = 0.58), as well as the relationship strong relationship between nitrogen fixing bacteria population and tomato plant height (r = 0.62). There is an effect of nitrogen fixing bacteria population on ammonium (R2 = 0.62) and nitrate (R2 = 0.53), nitrogen fixing bacteria population on plant N uptake (R2 = 0.34), nitrogen fixing bacteria population on plant height tomatoes (R2 = 0.38).
