Santoso, Agung Hari (2019) Pengaruh Kombinasi Pupuk Nano Dan Npk Anorganik Pada Pertumbuhan Dan Hasil Tanaman Pakcoy (Brassica Chinensis L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Sayuran merupakan komoditi utama yang paling diminati oleh penduduk Indonesia, berbagai komoditi sayuran tersedia, baik di pasar tradisional maupun modern. Diantara berbagai jenis sayuran, sawi merupakan salah satu komoditi yang mempunyai nilai prospek dan komersial yang cukup tinggi. Hasil yang maksimal perlu adanya suatu usaha dan prosedur budidaya yang baik tanpa mengesampingkan dampak negatif lingkungan sekitar. Penggunaan pupuk anorganik secara berlebihan dikalangan petani kerap terjadi dengan asumsi meningkatkan hasil panen. Menurut Lestari (2009) pupuk anorganik juga memiliki kelemahan, yaitu pemberian secara terus menerus dapat merusak tanah, dosis yang berlebihan dapat mengakibatkan kerusakan dan kematian tanaman dan dapat mengakibatkan pencemaran dan kerusakan lingkungan. Salah satu upaya untuk mengurangi dampak dari penggunakan pupuk anorganik yang berlebihan ialah menggunakan pupuk nanoteknologi. Pupuk nanoteknologi memiliki ukuran 1 nm = 10-9 µm hanya dibutuhkan dalam jumlah yang sedikit dan mampu diserap tanaman secara optimal. Diharapkan pupuk nano mampu meningkatkan penyerapan hara, perlindungan tanaman, serta meningkatkan hasil tanaman dengan efisien dan menghematan sumberdaya lahan (Liu dan Lal, 2015). Penelitian dilaksanakan pada bulan Juni hingga Agustus 2018 di desa Karangduren, kecamatan Pakisaji, kabupaten Malang. Ketinggian tempat pada lokasi penelitian 400-700 mdpl, dengan suhu harian berkisar antara 22°C – 28°C dan curah hujan 538,8 mm per tahun. Peralatan yang digunakan dalam penelitian ini diantaranya cangkul, tugal, gembor, meteran, timbangan digital, penggaris, kamera, tray, kertas label Bahan yang digunakan yaitu pakcoy varietas Flamingo, pupuk nano Ultra Gen, dan pupuk Urea (N), SP36 (P) dan KCl (K). Metode yang digunakan ialah Rancangan Acak Kelompok (RAK) sehingga didapatkan 7 perlakuan dan setiap perlakuan diulang sebanyak 4 kali. P1 = 100% NPK tunggal + 0% pupuk nano, P2 = 80% NPK tunggal + 20% pupuk nano, P3 = 60% NPK tunggal + 40% pupuk nano, P4 = 40% NPK tunggal + 60% pupuk nano, P5 = 20% NPK tunggal + 80% pupuk nano dan P6 = 0% NPK tunggal + 100% pupuk nano. Variabel pengamatan pertumbuhan meliputi tinggi tanaman, jumlah daun perhelai, dan luas daun. Variabel pengamatan hasil meliputi bobot segar total konsumsi perhektar bobot segar pertanaman, diameter bonggol dan kadar klorofil. Data pengamatan yang diperoleh dianalisis dengan menggunakan analisis ragam (uji F) pada taraf 5%. Bila hasil pengujian diperoleh perbedaaan yang nyata antar perlakuan maka dilanjutkan dengan uji perbandingan antar perlakuan dengan menggunakan Beda Nyata Terkecil (BNT) pada taraf 5 %. Hasil penelitian menunjukkan bahwa perlakuan 60% NPK + 40% pupuk nano menghasilkan panen sebesar 32,87 ton/ha, lebih tinggi dari pada 0% NPK + 100% pupuk nano menghasilkan panen sebesar 14,83 ton ha-1 dengan peningkatan hasil 55%.
English Abstract
Vegetables are the main commodity most in demand by the people of Indonesia, various vegetable commodities are available, both in traditional and modern markets. Among the various types of vegetables, mustard is one commodity that has high prospect and commercial value. Currently pakcoy is widely developed in the Philippines and Malaysia, in Indonesia and Thailand. In 2016, production of mustard contribution reached 601,20 ton ha-1 (Central Bureau of Statistics, 2018). Growth and development of pakcoy will not be separated from the role of nutrient availability in the soil. Maximum results need a good business and cultivation procedure without neglecting the negative impact of the surrounding environment. Excessive use of inorganic fertilizers among farmers often occurs with the assumption of increasing yields. According to Lestari (2009), Inorganic fertilizers also have the disadvantage that continuous addition can damage the soil, excessive doses can result in damage and death of the plant and can lead to pollution and environmental damage. One attempt to reduce the impact of excessive use of inorganic fertilizers is to use nanotechnology fertilizers. Nanotechnology fertilizer has a size of 1 nm = 10-9 μm is only needed in small amounts and can be absorbed plants optimally. Nanotechnology (nanofertilizer) is a product that delivers nutrients to plants in nanoparticle encapsulation systems. Encapsulation or encapsulation of plant nutrients is one application of nanotechnology that can be done in three ways: (1) nutrient elements wrapped in nanopore material, (2) nutrient elements wrapped with thin films / polymer films, and (3) delivered as particles colloidal or nanometer-sized emulsions (Rai and Dev, 2012). It is expected that nano fertilizer can increase nutrient uptake, crop protection, and improve crop yield efficiently and save land resources (Liu and Lai, 2015). The research conducted from June to August 2018 in Karangduren village, Pakisaji sub-district, Malang regency. The elevation of the site at the study site is 400-700 mdpl, with daily temperature ranging from 22 ° C - 28 ° C and rainfall 538,8 mm per year. Equipment used in this research include hoes, tugal, gembor, meter, digital scales, ruler, camera, tray, paper label Materials used are pakcoy varieties Flamingo, Ultra Gen nano fertilizer, Urea (N), SP36 and KCl (K). The method used was Randomized Block Design (RBD) with 7 treatments and each treatment was repeated 4 times. P1 = 100% NPK + 0% nano fertilizer, P2 = 80% NPK + 20% pupuk nano, P3 = 60% NPK + 40% nano fertilizer, P4 = 40% NPK + 60% nano fertilizer, P5 = 20% NPK + 80% nano fertilizer dan P6 = 0% NPK + 100% nano fertilizer. Observations of growth variable are plant height, leaf number of leaf and leaf area. Observation of yieald variable are total of fresh weight consumption ha-1, fresh weight per plant, diameter of hump and analyze chlorophyl. The observed data obtained were analyzed using variance analysis (F test) at 5% level. When the test results obtained a real difference between treatments then continued with the comparison test between treatments using the Least Significant Difference (LSD) 5% level.The results showed that, treatment of 60% NPK + 40% nano fertilizer yields 32,87 ton ha-1 of harvest, higher than 0% NPK + 100% nano fertilizer yields 14,83 tons ha-1 of harvest with an increase in yield 55%.
