-, Anatasia (2019) Pengendalian Gulma Pada Tanaman Kedelai Hitam (Glycine Soja L.) Var. Detam 2. Sarjana thesis, Universitas Brawijaya.
Abstract
Tanaman kedelai hitam (Glycine soja L.) merupakan tanaman semusim yang merupakan komoditas pangan utama ketiga setelah tanaman padi dan jagung. Namun untuk produksi kedelai hitam di Indonesia masih sangat rendah. Faktor yang menyebabkan adalah cara bercocok tanam yaitu pemeliharaan kurang intensif dan adanya persaingan terhadap gulma, bila pemeliharaannya kurang intensif maka tanaman kedelai akan bersaing dengan gulma, akibatnya hasil panen dapat menurun. Untuk meningkatkan produksi kedelai hitam di Indonesia diperlukan upaya salah satu nya pengendalian gulma. Adapun tujuan dari peneltian ini untuk mengetahui dosis herbisida dan pengaruh aplikasi dari pemberian herbisida pendimethalin dan metribuzin pada tanaman kedelai hitam varietas detam 2. Hipotesis yang diajukan perbedaan dosis dan herbisida yang digunakan dalam pengendalian gulma mempengaruhi pertumbuhan dan hasil tanaman kedelai hitam. Penelitian dilaksanakan pada bulan Oktober 2016 sampai bulan Desember 2016 di kebun percobaan Fakultas Pertanian Universitas Brawijaya, Jatimulyo, Malang. Alat yang digunakan antara lain petak kuadran, knapsack sprayer, ember, pengaduk, gelas ukur, gunting, amplop, kertas label, tali rafia, plastik, oven, spidol, oven, roll meter, sabit, kamera dan timbangan. Bahan yang digunakan dalam penelitian ini adalah benih kedelai hitam varietas detam 2 , herbisida pendimethalin, herbisida metribuzin, pupuk urea, KCl, dan SP-36. Pada penelitian ini menggunakan Rancangan Acak Kelompok (RAK). Terdiri dari 8 perlakuan herbisida dengan 4 kali ulangan sehinga terdapat 32 petak percobaan. Perlakuan yang dilakukan adalah (P0) Bergulma, (P1) Bebas gulma, (P2) Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST, (P3) Pendimethalin 1,50 kg ha-1 aplikasi 0 HST + Penyiangan 21 HST, (P4) Pendimethalin 2,25 kg ha-1 aplikasi 0 HST, (P5) Metribuzin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST, (P6) Metribuzin 1,50 kg ha-1 aplikasi 0 HST, (P7) Pendimethalin 0,75 ha-1 + Metribuzin 1,50 kg ha-1 aplikasi 0 HST. Pengamatan pada tanaman kedelai hitam meliputi tinggi tanaman, jumlah daun, jumlah bunga, luas daun pada waktu 2,4,6,8 MST dan pengamatan panen bobot kering total tanaman, jumlah biji, jumlah polong, bobot 100 biji, bobot polong, bobot biji. Untuk pengamatan gulma meliputi dominasi gulma, dan bobot kering gulma total. Data pengamatan yang telah diperoleh akan dianalisis menggunakan analisis ragam (Uji F) pada taraf 5%. Apabila terdapat beda nyata (F hitung > F tabel 5%), maka akan dianjutkan dengan uji lanjutan Beda Nyata Terkecil (BNT) dengan taraf 5%.akuan Berdasarkan hasil penelitian pada parameter tinggi tanaman, jumlah daun, jumlah bunga, luas daun, jumlah biji, jumlah polong, dan bobot polong terjadi perbedaan yang nyata antar perlakuan. Nilai tertinggi pada parameter tinggi tanaman didapatkan pada perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST. Sebesar 46,50. Jumlah daun pada perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST sebesar 92, jumlah bunga pada perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST +ii Penyiangan 21 dan 42 HST sebesar 92,75. Sedangkan luas daun terbesar terdapat pada perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST sebesar 684,75. Untuk peubah panen, jumlah polong nilai tertinggi pada perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST sebesar 61,75. Jumlah biji tertinggi pada perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST sebesar 154,50. Serta bobot polong perlakuan Pendimethalin 0,75 kg ha-1 aplikasi 0 HST + Penyiangan 21 dan 42 HST sebesar 31,02.
English Abstract
Black Soybean (Glycine soja L.) is an annual crop which is the third major food commodity after rice and corn. But the production of black soybean in Indonesia is still very low. The factor that causes it to happen is the method of farming, which is less intensive maintenance and copetition from weeds, if the maintenance is less intensive, the soybean plants will compete with weeds and resulting in declining yields. Weed control is one of the effort that needed to increase the production of black soybeans in Indonesia. The purpose of this study was to determine the dose of herbicide and the effect of application of the pendimenthalin herbicide and metribuzin on the black soybean varieties of detam 2. The hypothesis proposed in this research is the difference in dosage and herbicides used in weed control can affect the growth and yield of black soybean plants. The study was conducted in October 2016 until December 2016 in the experimental garden of the Faculty of Agriculture, Brawijaya University, Jatimulyo, Malang. The tools used in this research include quandrant tiles, knapsack sprayers, buckets, stirrers, measuring cups, scissors, envelopes, label paper, raffia, plastic, ovens, markers, roll meters, sickles, cameras and scales. The materials used in this study was balck soybean seeds, variety of detam 2, pendimenthalin herbicide, metribuzin herbicide, urea fertilizer, KCL and SP-36. This study used a Randomized Block Design (RDB) that consist of 8 herbicide treatments with 4 repitition so that there were 32 experimental plots. The treatment carried out was (P0) Bergulma, (P1) Weed free, (P2) Pendimethalin 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST, (P3) Pendimethalin 1.50 kg ha-1 application 0 HST + Weeding 21 HST, (P4) Pendimethalin 2.25 kg ha-1 application 0 HST, (P5) Metribuzin 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST, (P6) Metribuzine 1.50 kg ha -1 application 0 HST, (P7) Pendimethalin 0.75 ha-1 + Metribuzin 1.50 kg ha-1 application 0 HST. Observations on black soybean plants included plan height, number of leaves, number of flowers, leaf area at 2,4,6,8 MST and the oberservations of total plant dry weight, number of seeds, number of pods, weight of 100 seeds, pod weight, seed weight. Oberservation of weeds included the dominance of weeds and total weight of dry weed. Obeservation data that has been obtained will be analyzed using Analysis of Variance (Test F) at the level of 5%. If there is a significant difference (F count > F table to 5%) then it will be followed by the Smalles Significant Difference test with 5% level. Based on the result of the research on parameters of plant height, number of leaves, number of flowers, leaf area, number of seeds, number of pods and the weight of pods, there were a significant differences between treatments. The highest value on the parameters of plant height was obtained at the Pendimethalin treatment 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST at 46.50.iv The number of leaves in the Pendimethalin treatment was 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST by 92, the number of flowers in the Pendimethalin treatment was 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST of 92.75. While the largest leaf area was found in the Pendimethalin treatment 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST at 684.75. For harvest variables, the highest number of pods in the Pendimethalin treatment was 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST at 61.75. The highest number of seeds in the Pendimethalin treatment was 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST at 154.50. As well as pod weight treatment of Pendimethalin 0.75 kg ha-1 application 0 HST + Weeding 21 and 42 HST of 31.02.
