| Judul Artikel | Kajian Agihan Hara N Tanah Sawah dan Kadarnya pada Tanaman Padi Sawah di Sub DAS Serayu Hilir Wilayah Kecamatan Adipala, Kabupaten Cilacap |
| Abstrak | Penelitian ini bertujuan untuk: (1) mengetahui distribusi unsur hara nitrogen tanah di lahan sawah di wilayah Sub DAS Serayu Hilir Kecamatan Adipala, Kabupaten Cilacap, (2) mengetahui korelasi antara sebaran unsur hara nitrogen total tanah dengan kadar nitrogen pada jaringan tanaman dan hasil padi sawah di wilayah Sub DAS Serayu Hilir Kecamatan Adipala, Kabupaten Cilacap, dan (3) menentukan rekomendasi pemberian dosis pupuk N di lahan sawah di wilayah Sub DAS Serayu Hilir Kecamatan Adipala, Kabupaten Cilacap. Penelitian dilaksanakan pada bulan November 2021 sampai Februari 2021 di Kecamatan Adipala, Kabupaten Cilacap dan Laboratorium Tanah dan Sumberdaya Lahan, Fakultas Pertanian, Universitas Jenderal Soedirman. Metode penelitian dilakukan dengan penentuan titik sampel sebanyak 11 titik diawali dengan pembuatan peta SLH (Satuan Lahan Homogen) dengan skala 1:50.000 dengan cara menggabungkan (overlay) Peta Administrasi, Peta Jenis Tanah, Peta Kelerengan, dan Peta Penggunaan Lahan. Variabel ukur yang digunakan yaitu pH H 2 O, potensial redoks, N total tanah, Kadar N pada jaringan tanaman, keadaan iklim, varietas tanaman, serta hasil tanaman padi. Hasil penelitian menunjukkan bahwa sebaran hara nitrogen di Kecamatan Adipala memiliki status sangat tinggi. Varietas tanaman padi yang dibudidayakan saat penelitian di Kecamatan Adipala terdiri atas Ciherang, Logawa, Inpari 1, IR64, Situ Bagendit, dan Jongsu. Keadaan iklim di Kecamatan Adipala termasuk iklim yang sesuai untuk pertanaman padi. Nilai N total tanah memiliki koefisien determinan sebesar 26,55% terhadap hasil tanaman padi, sedangkan kadar N jaringan hanya memiliki koefisien determinan 25,23% terhadap hasil tanaman padi. Rekomendasi pemupukan di lahan penelitian pada musim tanam berikutnya tidak dibutuhkan karena status unsur hara N sudah sangat tinggi dan sudah sesuai kebutuhan. |
| Abstrak (Inggris) | This study aims to determine: (1) distribution of soil potassium nutrients in This study aims to: (1) find out distribution of soil nitrogen nutrients in paddy fields in Serayu Watershed Downstream, Adipala District, Cilacap Regency, (2) find out correlations of soil total nitrogen with level of N in plant and rice yields in Serayu Watershed Downstream, Adipala District, Cilacap Regency, and 3) Determine fertilizer recommendations nitrogen in paddy soil in Serayu Watershed Downstream, Adipala District, Cilacap Regency. The study was conducted in December 2021 to March 2021 in Adipala District, Cilacap Regency and the Land and Land Resources Laboratory, Faculty of Agriculture, Jenderal Soedirman University. The study method was conducted by determining 9 sample points by the making of SLH (Homogeneous Land Unit) map with a scale of 1:50.000 by overlaying the Adipala Disctrict Administration Map, the Soil Type Map, the Slope Map, and the Land Use Map. The variables mesured were were pH H 2 O, redox potential, soil total N, level of N in plant, climatic conditions, plant varieties, and wet grain rice yields. The results showed that the distribution of nitrogen nutrients in Adipala District had a very high status. The paddy varieties cultivated during research in Adipala District consist of Ciherang, HT Logawa, Inpari 32, and IR64. The climatic conditions in Adipala District are suitable for rice cultivation. Total soil N value has a determinant coefficient of 26.55% on rice yields, while tissue N content only has 25.23% of rice yields. Recommendations for fertilization in the research land in the next growing season are not needed because the N nutrient status is already very high and is in accordance with the needs. |
