| Judul Artikel | PENGARUH DOSIS PUPUK KOTORAN AYAM DAN KAPUR DOLOMIT TERHADAP SIFAT KIMIA TERPILIH PADA ULTISOL UNTUK MENDUKUNG PERTUMBUHAN DAN HASIL CAISIM (Brassica juncea L.) |
| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk (1) mengetahui dosis pupuk kotoran ayam optimal terhadap sifat kimia terpilih ultisol untuk mendukung pertumbuhan dan hasil caisim (2) mengetahui dosis kapur dolomit optimal terhadap sifat kimia terpilih ultisol untuk mendukung pertumbuhan dan hasil caisim (3) mengetahui kombinasi dosis pupuk kotoran ayam dan kapur dolomit optimal terhadap sifat kimia terpilih ultisol untuk mendukung pertumbuhan dan hasil caisim. Penelitian dilakukan dengan percobaan polybag di screen house Fakultas Pertanian, Laboratorium Agronomi dan Hortikultura, Universitas Jenderal Soedirman serta analisis tanah dilakukan di ICBB Bogor dimulai dari bulan Februari 2020 sampai Mei 2020. Perlakuan terdiri dari dua faktor yaitu dosis pupuk kotoran ayam 5 ton/ha, 10 ton/ha dan 15 ton/ha. Faktor kedua kapur dolomit 2,2 ton/ha, 3,3 ton/ha dan 4,4 ton/ha. Percobaan dirancang dengan menggunakan rancangan acak kelompok lengkap (RAKL) masing-masing kombinasi perlakuan diulang dua kali. Variabel yang diamati meliputi pH tanah (H_2 O), daya hantar listrik, C-rganik tanah, P tersedia, tinggi tanaman (cm), jumlah daun (helai), panjang akar (cm), bobot akar segar (g), dan bobot tajuk segar (g). Hasil Penelitian menunjukan : 1). Dosis pupuk kotoran ayam 15 ton/ha dan kapur dolomit 4,4 ton/ha mampu memperbaiki sifat kimia tanah ultisol yaitu pH tanah (H_2 O), daya hantar listrik, C-rganik tanah dan K2D3 dengan dosis pupuk kotoran ayam 10 ton/ha dan kapur dolomit 4,4 ton/ha pada P tersedia 2). Dosis pupuk kotoran ayam berpengaruh sangat nyata terhadap jumlah daun namun tidak berpengaruh nyata terhadap tinggi tanaman, panjang akar, bobot akar segar, dan bobot tajuk segar. 3). Dosis kapr dolomit berpengaruh nyata terhadap jumlah daun, berpengaruh sangat nyata terhadap panjang akar namun tidak berpengaruh nyata terhadap tinggi tanaman, bobot akar segar dan bobot tajuk segar. 4). Kombinasi dosis pupuk kotoran ayam dan kapur dolomit berpengaruh nyata terhadap sifat kimia terpilih ultisol dan panjang akar namun tidak berpengaruh nyata terhadap tinggi tanaman, jumlah daun, bobot akar segar dan bobot tajuk segar. |
| Abtrak (Bhs. Inggris) | This study aims to (1) determine the optimal dose of chicken manure fertilizer against the chemical properties of selected ultisols to suport growth and results of caisim (2) determine the optimal dose of dolomite lime on the chemical properties of selected ultisols to suport growth and results of caisim (3) determine the optimal dose combination of chicken manure and dolomite lime on the chemical properties of selected ultisols to suport growth and results of caisim. The research was carried out by experimenting using polybags in screen house of the Agricultural Faculty, Agronomy and Horticultural Labory of the Agricultural Faculty, Jenderal Soedirman University and soil analysis was carried out at ICBB Bogor starting from February 2020 to May 2020. The treatment consisted of two factors, namely the dose of chicken manure fertilizer 5 tons / ha, 10 tonnes / ha and 15 tonnes / ha. The second factor is dolomite lime 2.2 tons / ha, 3.3 tons / ha and 4.4 tons / ha. The experiment was designed using a complete randomized block design (RAKL), each treatment combination was repeated twice. The variables observed included soil pH (H_2 O), electrical conductivity, soil moisture, available P, plant height (cm), number of leaves (strands), root length (cm), fresh root weight (g), and weight. fresh header (g). The results showed: 1). The dose of 15 tonnes / ha of chicken manure and 4.4 tonnes / ha of dolomite lime can improve the chemical properties of ultisol soil, namely soil pH (H_2 O), electrical conductivity, soil C-organic and K2D3 with a dose of 10 ton / ha chicken manure and dolomite lime 4.4 tonnes / ha at available P 2). The dose of chicken manure had a very significant effect on the number of leaves but did not significantly affect plant height, root length, fresh root weight, and fresh shoot weight. 3). Dolomite cap dose significantly affected the number of leaves, had a very significant effect on root length but had no significant effect on plant height, fresh root weight and fresh shoot weight. 4). The combination of chicken manure and dolomite lime doses had a significant effect on the chemical properties of selected ultisols and root lengths but did not significantly affect plant height, number of leaves, fresh root weight and fresh shoot weight. |
