| Judul Artikel | APLIKASI PUPUK HAYATI MIKORIZA-TRICHODERMA YANG DIKOMBINASI DOSIS PUPUK N, P, K PADA TANAMAN BAWANG MERAH |
| Abstrak | tujuan penelitian ini(1)mengetahui pengaruh pemberian dosis pupuk hayati mikoriza-Trichoderma terhadap pertumbuhan dan hasil bawang merah, (2)menentukan pengurangan dosis pupuk N,P,K yang optimal terhadap pertumbuhan dan hasil bawang merah. (3)mengetahui kombinasi terbaik pupuk hayati mikoriza-Trichoderma dan pengurangan dosis pupuk N,P,K terhadap pertumbuhan dan hasil bawang merah. Penelitian dilaksanakan pada bulan April sampai Juni 2019 di lahan Desa Kaliori, Kecamatan Kalibagor, Kabupaten Banyumas dan Laboratorium Agronomi dan Hortikultura Fakultas Pertanian, Universitas Jenderal Soedirman. Rancangan yang digunakan adalah RAKL faktorial dengan 3 kali ulangan. Faktor pertama dosis pupuk hayati mikoriza-Trichoderma yang terdiri atas 5 g pupuk hayati mikoriza–5 g Trichoderma, 15 g pupuk hayati mikoriza–15 g Trichoderma, 25 g pupuk hayati mikoriza –25 g Trichoderma. Faktor kedua pengurangan dosis N,P,K yang terdiri atas tanpa pengurangan dari dosis anjuran, pengurangan 25% dan 50% dari dosis anjuran. Variabel yang diamati adalah tinggi tanaman,jumlah daun,jumlah anakan,luas daun, bobot tajuk segar, bobot tajuk kering, jumlah umbi rumpun-1, volume umbi, bobot umbi segar, bobot umbi kering, bobot umbi petak-1, hasil umbi kering. Data yang diperoleh dianalisis uji F, apabila ada pengaruh nyata diuji lanjut dengan DMRT. Hasil penelitian menunjukkan bahwa (1) pemberian pupuk hayati 5 g mikoriza-5 g Trichoderma meningkatkan jumlah daun, jumlah anakan, luas daun, bobot tajuk segar, bobot tajuk kering. (2) Pengurangan dosis pupuk N, P, K sebanyak 50% dari dosis anjuran meningkatkan jumlah daun, jumlah anakan dan jumlah umbi rumpun-1. Pada pemberian pupuk N, P, K sesuai dosis anjuran meningkatkan luas daun, bobot tajuk segar, . (3)Kombinasi terbaik untuk luas daun bawang merah adalah 15 g mikoriza – 15 g Trichoderma dan sesuai dosis anjuran, untuk volume umbi terbaik bawang merah 25 g mikoriza – 25 g Trichoderma dan pengurangan 25% dosis N,P,K anjuran. |
| Abstrak (Inggris) | This study aimed to (1) determine the effect of mycorrhizae-Trichoderma doses on the growth and yield of shallots, (2) determine the optimal reduction of N, P, K fertilizer doses on the growth and yield of shallots. (3) know the best combination of mycorrhizae-Trichoderma doses and N, P, K fertilizer doses to the growth and yield of shallots. The study was conducted from April to June 2019 on the land of Kaliori Village, Kalibagor District, Banyumas Regency and Agronomy and Horticulture Laboratory, Faculty of Agriculture, the Jenderal Soedirman University. The experimental design used was a factorial Randomized Complete Block Design with 2 factors and 3 replications. The first factor was the doses of mycorrhizae-Trichoderma fertilizer consisting of 3 levels, namely 5 g mycorrhizae - 5 g Trichoderma, 15 g mycorrhizae - 15 g Trichoderma, 25 g mycorrhizae - 25 g Trichoderma. The second factor was doses of N, P, K which consists of 3 levels, namely, the recommended dose, a reduction of 25% from the recommended dose, a reduction of 50% from the recommended dose. The observed variables were plant height, number of leaves, number of tillers, leaf area, weight of crop shoots, weight of dry shoots, number of bulbs in one cluster, bulbs volume, fresh bulbs weight, dry bulbs weight, bulbs weight in one cluster, yield dry bulbs. The data were analyze using F test followed by DMRT at the 5% level if there was a significantly different among observed values. Results showed that (1) the application of 5 g mycorrhizae-5 g Trichoderma increased the number of leaves, number of tillers, leaf area, weight of harvest shoots, weight of dry shoots. (2) Reducing the dosage of N, P, K fertilizer by 50% from the recommended dosage can increase the number of leaves, number of tillers and number of bulbs in one cluster, while in the variable number of leaves, leaf area, fresh weight shoots, shoots weight dry, fresh bulbs weight of in one cluster, dry bulbs weight of in one cluster still higher at recommended dosage. (3) the best combination for leaf area of shallot with 15 g mycorrhizae-15 g Trichoderma and the recommended dose. for the best bulbs volume of shallots 25 g mycorrhizae - 25 g Trichoderma and a 25% reduction in recommended dosages. Since there was no significant effect of all combination of treatments on yield of dried bulbs hectare-1, farmers should apply 5 g of mycorrhizae-5 g Trichoderma and a 50% reduction in recommended dosages of N, P, K fertilizer on soil if shallot was cultivated. |
