Kurniawan, BayuAdi (2013) Pengaruh Jumlah Pemberian Air Terhadap Respon Pertumbuhan Dan Hasil Tanaman Tembakau (Nicotiana Tabaccum L.). Sarjana thesis, Universitas Brawijaya.
Abstract
Tembakau ( Nicotiana tabacum L.) mempunyai peran cukup besar dalam perekonomian nasional melalui cukai dan pajak, penyediaan lapangan kerja serta dampak ganda ( multiplier effect ) pengadaan dan perdagangan tembakau. Kebijakan penanaman tembakau tersebut terus dilanjutkan oleh pemerintah Indonesia melaui perusahaan negara perkebunan (PNP). Tembakau di Jawa Timur merupakan komoditi unggulan yang bernilai tinggi dibandingkan komoditi palawija lainnya. Masalah utamanya adalah rendahnya mutu karena saat tanam dan pemberian air yang kurang tepat.Air adalah salah satu komponen fisik yang sangat penting dan diperlukan dalam jumlah banyak untuk pertumbuhan dan perkembangan tanaman. Sekitar 85-90 % dari bobot segar sel-sel dan jaringan tanaman tinggi adalah. Air berfungsi sebagai pelarut hara, penyusun protoplasma, bahan baku fotosintesis dan lain sebagainya. Kekurangan air pada jaringan tanaman dapat menurunkan turgor sel, meningkatkan konsentrasi makro molekul serta mempengaruhi membran sel dan potensi aktivitas kimia air dalam tanaman. Tujuan dari penelitian ini adalah untuk mempelajari dan mengetahui perbandingan pertumbuhan dan hasil tanaman tembakau dengan jumlah pemberian air yang berbeda dari total kebutuhan air normal tanaman tembakau. Penelitian dilaksanakan pada bulan Desember s/d Maret 2012 di kebun percobaan Jati Kerto Fakultas Pertanian Universitas Brawijaya Malang,yang terletak pada ketinggian 583 m di atas permukaan laut. Rancangan yang digunakan adalah Rancangan Acak Kelompok (RAK) 5 perlakuan pemberian air dengan 5 ulangan. Berdasarkan perlakuan pemberian air terhadap tanaman tembakau,hasil tertinggi terhadap variabel pengamatan jumlah daun, luas daun, bobot segar daun dan laju pertumbuhan tanaman terjadi pada perlakuan P4, yaitu dengan pemberian air 25% lebih banyak dari jumlah kebutuhan air normal (100%).Hasil tertinggi yang diperoleh pada variabel pengamatan tersebut diduga sebagai akibat ketersediaan air di dalam tanah cukup bagi kebutuhan tanaman tembakau. Sehingga tanpa ditambahkan jumlah air yang lebih, kebutuhan air tanaman sudah mencukupi.
English Abstract
Tobacco (Nicotiana tabacum L.) has a significant role in the national economy through customs and taxes, employment and the double impact (multiplier effect) procurement and trade in tobacco. The policy for Tobacco continued by the Indonesian government through the state plantation companies (PNP). Tobacco in East Java is a high-value commodity crops compared to other commodities. The main problem is the low quality due to the time of planting and the lack of proper water supply. Water is one of the physical components of a very important and needed in large quantities for the growth and development of the plant. Approximately 85-90% of the fresh weight of the cells and tissues of plants is high. Water serves as a solvent for nutrients, constituent protoplasm, the raw material of photosynthesis and so forth. Lack of water in the plant tissue can reduce cell turgor, increased concentrations of macro-molecules and affects the cell membrane and the potential chemical activity of water in plants . The purpose of this research is to study and compare the growth and result of tobacco plants with different watering intervals of total water demand normal tobacco plants. Research conducted in December 2012 - March 2013 at the experiment do at Jati Kerto farm of Brawijaya University in Malang, which is located at an altitude of 583 m above sea level. The design used was a randomized block design (RBD) 5 treatments with 5 replicates of water provision. Based on the provision of water to the treatment of tobacco plants, the highest result of the observation variable number of leaves, leaf area, leaf fresh weight and rate of plant growth occurs in P4 treatment, namely the provision of water 25% more than the normal amount of water requirement (100%). Results highest obtained in the observation variables thought to be due to the availability of water in the soil enough for the needs of the tobacco plant. So without the added amount of water is more, the crop water requirement is sufficient.
