dc.description.abstractIntensifikasi tebu keprasan lahan kering merupakan salah satu cara dalam rangka meningkatkan produksi gula nasional. Penelitian dilakukan bulan Agustus 2019 - Juli 2020 pada tebu keprasan pertama di lahan percobaan PT Kebun Tebu Mas, Lamongan, Jawa Timur dengan rancangan split split plot. Perlakuan terdiri atas 3 faktor yaitu varietas (PS 881 dan PS 862) sebagai petak utama, residual kompos blotong (taraf residual pupuk blotong 0, 5, dan 10 ton ha-1) sebagai anak petak, dan residual pupuk anorganik (residual pupuk 25%, 50%, 75%, dan 100% dosis rekomendasi) sebagai anak-anak petak. Hasil penelitian menunjukkan bahwa pertumbuhan varietas PS 862 lebih baik daripada PS 881 pada keragaan tinggi tanaman, panjang ruas, diameter, panjang batang, dan jumlah batang. Residual kompos blotong memiliki pengaruh nyata lebih baik pada taraf 10 ton ha-1 pada panjang ruas. Residual pupuk anorganik taraf 75% memiliki respon yang lebih baik pada peubah jumlah daun, jumlah tunas, jumlah batang dan diameter. Varietas PS 862 dengan 5 ton ha-1 residual kompos blotong menghasilkan bobot batang terbaik sebesar 0,48 kg m-1. Varietas PS 862 dengan 75% residual pupuk anorganik menghasilkan hasil tebu sebesar 78,52 ton ha-1 dan tidak berbeda nyata dengan residual 100% pupuk anorganik.id
dc.description.abstractIntensification of upland sugarcane is one way to increase national sugar production. The research was conducted in August 2019-July 2020 on the experimental field of PT Kebun Tebu Mas, Lamongan on the first ratooncane with a split-split plot design. The treatment consisted of three factors, variety (PS 881 and PS 862 as main plots), residual filter cake (0, 5, and 10 tons ha-1) as subplots, and inorganic fertilizer residues (25, 50, 75, and 100% recommended doses) as subsubplots. The results showed that growth and yield of PS 862 was better than PS 881 in the performance of plant height, internode length, diameter, stem length, and number of stems. The residue of blotong compost had a significantly better effect at the level of 10 tons ha-1 on internode length. Residual inorganic fertilizer level 75% had a better response to the variables of number of leaves, number of shoots, number of stems and diameter. The PS 862 with 5 tons ha-1 residual blotong compost produced the best stem weight of 0.48 kg m-1. The PS 862 variety with 75% residual inorganic fertilizer produced sugarcane yields of 78.52 tons ha-1 and was not significantly different from the residual 100% inorganic fertilizer.id
