| Judul Artikel | PENGARUH APLIKASI HERBISIDA TERHADAP FISIOLOGI, PERTUMBUHAN DAN HASIL TANAMAN JAGUNG MANIS (Zea mays Saccharata Sturt) |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk mengetahui tingkat efektivitas dan selektivitas dari herbisida berbahan aktif berbeda khususnya dalam mempengaruhi fisiologi, pertumbuhan dan hasil tanaman jagung manis. Penelitian ini dilaksanakan di Laboratorium Agronomi dan Hortikultura, Fakultas Pertanian, Universitas Jenderal Soedirman dan lahan tanaman jagung manis Kelurahan Mersi, Purwokerto Timur. Penelitian ini merupakan penelitian experimental dengan rancangan acak kelompok (RAK) satu faktor yaitu pengendalian gulma, terdiri atas 8 taraf dengan 4 ulangan. Variabel yang diamati yaitu meliputi identifikasi gulma pada fase sebelum tanam, 15 HST, 35 HST, luas daun, ILD, bobot basah tanaman, bobot kering tanaman, LAB, LPT, kandungan klorofil, kerapatan stomata, lebar bukaan stomata, tinggi tanaman, jumlah daun, kehijauan daun, panjang tongkol, diameter tongkol, jumlah biji tongkol, bobot tongkol, hasil panen per petak, hasil panen per hektar. Data hasil penelitian dianalisis menggunakan uji ANOVA, dan dilanjutkan Uji DMRT pada taraf kepercayaan 95% jika terdapat pengaruh perlakuan. Hasil penelitian aplikasi herbisida glifosat dan parakuat menunjukkan komposisi gulma yang sifatnya homogen berubah menjadi heterogen. Hal tersebut dapat dilihat dengan adanya jenis gulma baru yang teridentifikasi. Adapun setelah aplikasi herbisida atrazin, mesotrion dan nicosulfuron terjadi penurunan dominasi gulma. Aplikasi herbisida parakuat, atrazin dan mesotrion serta glifosat, atrazin, mesotrion dan nicosulforan memberikan hasil terbaik pada variabel fisiologi, pertumbuhan dan hasil panen jagung manis yaitu bobot kering tanama, laju pertumbuhan tanaman, tinggi tanaman, bobot panen per petak, bobot panen per hektar, luas daun, indeks luas daun, bobot basah tanaman. Adapun aplikasi herbisida glifosat, atrazin dan mesotrion memberikan hasil terbaik pada variabel pertumbuhan dan karakter hasil jagung manis yaitu jumlah daun, kehijauan daun, panjang tongkol jagung, diameter tongkol dan bobot tongkol. |
| Abtrak (Bhs. Inggris) | This research aims to determine the level of effectiveness and selectivity of herbicides with different active ingredients, especially in influencing the physiology, growth and yield of sweet corn plants. This research was carried out at the Agronomy and Horticulture Laboratory, Faculty of Agriculture, Jenderal Soedirman University and the Mersi sweet corn plantation, East Purwokerto. Research activities were carried out for 4 months, starting from July 2023 to October 2023. This research is researchexperimental with a randomized block design (RAK) with one factor, namely weed control, consisting of 8 levels with 4 replications. The variables observed included weed identification in the pre-planting phase, 15 HST, 35 HST, leaf area, leaf area index, plant wet weight, plant dry weight, LAB, LPT, chlorophyll content, stomata density, stomata opening width, plant height, number of leaves, leaf greenness, ear length, ear diameter, number of ear seeds, ear weight, harvest per plot, harvest per hectare. The research data were analyzed using the ANOVA test, and continued with the DMRT test at a confidence level of 95% if there was a treatment effect. The results of research on the application of glyphosate and paraquat herbicides show that the composition of weeds which were homogeneous changed to become heterogeneous. This can be seen by the presence of new weed types identified. Meanwhile, after application of the herbicides atrazine, mesotrione and nicosulfuron, weed dominance decreased. Application of the herbicides paraquat, atrazine and mesotrione as well as glyphosate, atrazine, mesotrione and nicosulforan gave the best results on physiological variables, growth and sweet corn yields, namely plant dry weight, plant growth rate, plant height, harvest weight per plot, harvest weight per hectare, leaf area, leaf area index, plant wet weight. The application of the herbicides glyphosate, atrazine and mesotrione gave the best results on the growth variables and yield characteristics of sweet corn, namely the number of leaves, leaf greenness, the length of the corn cob, diameter of the cob and the weight of the cob. |
