Tingkat kesuburan tanah dapat diperbaiki melalui pemberian bahan organik, hijauan tanaman ke dalam tanah atau diadakan rotasi tanaman. Kenaf merupakan tanaman semusim berumur 120 hari yang sesuai dirolasi dengan padi dan jagung. Penelitian rotasi kenaf dengan padi dan jagung dilaksanakan di Desa Canggu, Kecamatan Pare, Kabupaten Kediri pada musim tanam 1992/1993 sampai dengan 1994/1995 pada tanah regosol cokelat keabuan Tinggi tempat 70 meter di atas permukaan air laut dengan tipe iklim C3 menurut sistem klasiikasi Oldeman Tujuan penelitian untuk mengetahui pengaruh rotasi tanaman kenaf dengan tanaman padi dan jagung terhadap peningkatan hasil padi dan jagung setelah lanaman kenaf seta perubahan ciri-ciri tanah tetentu sepeti kandungan C, N dan KTK di lahan irigasi Perlakuan disusun dalam rancangan acak kelompok yang diulang sebanyak tiga kali. Seluruh perlakuan ada 12 macam rotasi. Ukuran petak 14 m x 10 m. Padi yang ditanam varietas IR-64, jagung varietas CPI dan kenaf He. G4. Jarak tanam padi, jagung dan kenaf beturut-turut 20 cm x 20 cm; 75 cm x 30 cm dan 20 cm x 15 cm Hasil penelitian menunjukkan bahwa frekuensi penanaman kenaf dapat meningkatkan kesuburan tanah yang meliputi C-organik. N-total dan KTK tanah, baik pada tahun petama maupun pada tahun petama dan kedua. Hasil padi pada tahun petama tanpa kenaf, satu dan dua kali tanam kenaf sebelum padi masing-masing sebesar 5.19, 5.25, dan 6.24 ton/ha. Pada tahun petama dan kedua tanpa tanam kenaf dua dan liga kali tanam kenaf sebelum padi, masing-masing sebesar 4 68, 4.98, dan 5.23 ton/ha. Hasil jagung pada tahun petama tanpa kenaf dan satu kali tanam kenaf sebelum jagung, masing-masing sebesar 3.70 dan 4 47 ton/ha.Kata kunci: Kenaf, rotasi tanaman, padi, jagung, irigasi, kesuburan tanah ABSTRACTEffect of kenaf rotation on paddy and corn yieldThe fetility status of soil could be improved through the application of organic matter, fresh green plant or crop rotation practices. An experiment on kenaf-paddy-com rotalion was conducted ai Canggu Village, Pare Sub District, Kediri District from 1992/1993 to 1994/1995 on grey brown regosol. The altitude was 70 m above sea level, and the climate type was C3 according to Oldeman classiication. The purpose of the study was to know the effect of kenaf rotation on paddy and com yields and some soil characteristic change ater kenaf planting in irrigalcd land. The cxperimenl was arranged in a randomized block design with three replications. All treatments consisted of 12 kinds of rotations. Plot size was 14 m x 10 m. The variety of paddy, com, and kenaf used in this experiment were IR-64, CPI and He G4 respectively. The plant spacing were 20 cm x 20 cm; 75 cm x 30 cm and 20 cm x 15 cm respectively. The result indicated that the frequency of growing kenaf enhanced C- organic, Total-N and CEC status. Paddy yield in the irst year of growing none, once and two times of kenaf before paddy obtained 5.19; 5.25 and 6.24 ton/ha respectively. Paddy yield in the irst and second year of growing none, two and three times of kenaf before paddy obtained 4.68; 4.98 and 5.23 ton/ha respectively. Corn yield in the irst year of none and once of kenaf before com obtained 3.70 and 4.47 ton/ha respectively.Key words : Kenaf, plant rotation, paddy, com, irrigation, soil fetility

Hasil samping dari limbah pabrik gula diantaranya adalah blotong atau dikenal dengan scbulan "ilter press mud". Secara umum bentuk dari blotong berupa serpihan scrat-scrat tebu yang mempunyai komposisi humus, N-total, C/N, P2O5, K20, CaO dan MgO, cukup baik untuk dijadikan bahan pupuk organik. Blotong dapat memperbaiki isik tanah, khususnya meningkatkan kapasitas menahan air. menurunkan laju pencucian hara dan memperbaiki drainase tanah. Manfaat lain dari blotong dapat menetralisir pengaruh Al<u , sehingga ketersediaan P dalam tanah lebih tersedia. Tujuan penelitian adalah untuk mendapatkan dosis blotong dan pupuk fosfat alam yang sesuai pada tanaman rosela di lahan podsolik merah kuning Kalimantan Selatan. Penelitian dilaksanakan di senlra pengembangan Intensiikasi Serat Karung Rakyat yaitu di daerah tranmigrasi Desa Sabuhur II, Kecamatan Jorong, Kabupaten Tanah Laut, Kalimantan Selatan dari bulan September 1998 sampai dengan bulan April 1999 Kctinggian lempal 50 m di atas permukaan air laut dengan tipe iklim B2 yaitu 2-3 bulan kering dan 7-9 bulan basah. Topografi dataran rendah dan tadah hujan. Perlakuan disusun dalam rancangan acak kelompok faktoial yang diulang sebanyak 3 kali. Sebagai faktor petama adalah blotong dengan dosis : 3, 4, dan S ton per hektar, sedang faktor kedua pupuk fosfat alam dengan dosis : 40: 60, 80, dan 100 kg P,Oj per hektar. Seluruh perlakuan terdiri dari 12 kombinasi blotong dan fosfat alam Ukuran petak yang digunakan 4 m x 6 m dengan jarak tanam 20 cm x 20 cm. Setiap lubang lanam bcrisi satu tanaman Hasil penelitian menunjukkan bahwa pemberian 5 ton blolong + 40 Pj05 per hektar ditambah dengan pupuk dasar 90 kg N * 60 kg K2O menghasilkan pertumbuhan linggi tanaman, diameter batang, berat brangkasan, berat kulil, hasil serat kering dan kckuatan serat rosela, masing-masing sebesar 336.35 cm; 14.73 mm; 536 kg/petak; 147 50 kg'petak; 2.775 ton per hektar dan 31 50 granvtex.Kala kunci: Rosela, blotong, fosfal alam, podsolik merah kuning, Kalimantan ABSTRACT The use ofilter press mud and rock phosphate on roselle cultivation in red yellow podsolic soil in South KalimantanThe waste of sugarcane factory was blotong or called "ilter press mud". As an organic fetilizer, blotong contains C, N-total, C/N, P2OJ, K2O, CaO and MgO. The filter press mud is believed to have the capacity in improving soil physic, especially water rclcntion, leaching ability and drain capacity. Orther advantage is that it is capable of netralizing the effect of exchangable Al, thus improving the soluble P in the soil. The improvement in soil physic due to the application of ilter press mud is expected to increase the crop yield The purpose of this experiment was to ind out the appropriate dose of iller press mud and rock phosphate on roselle cultivation in the red yellow podsolic soil in South Kalimantan The experiment was conducted in the central growing areas in red yellow podsolic soil al the Sabuhur II transmigration silc, Jorong Sub District, Tanah I-aut District, South Kalimantan Province from September 1998 to April 1999 Location attitude was 50 m above sea level and climate type was B2 with 7-9 wet months and less 2-3 dry months. The topography was low land with rain fed land The experiment was arranged factorially in a randomized block design with three replications. The irst factor was filter press mud with a rate of 3; 4 and 5 Ions per hectare While the second factor was rock phosphate with the rate of 40; 60; 80, and 100 kg P;0> per hectare. The treatments were 12 ertilizer combination of filler press mud Plating space was 20 cm x 20 cm and Ihe plot size was 4 m x 6 m with one plant per hole 'Die result showed that 5 tons filter press mud * 40 kg P2Oj rock phosphate per hectare and added with 90 kg N ^ 60 kg K2O gave the best performance The plant height, stem diameter, fresh weight, bark weight, iber yield and iber strength were 336.35 cm; 14.73 mm; 536 kg/plot; 147.50 kg/plot; 2 775 tons per hectare and 31.50 gram/tex respectivelly.Key words : Roselle, ilter press mud, rock phosphate, red yellow podsolic, Kalimantan

Tanaman rami (Boehmeria nivea) dipanen setiap dua bulan, sehingga hara yang tcrangkut melalui panen cukup besar. Untuk itu dilakukan percobaan pembeian zat pengatur tumbuh (ZPT) dan pupuk pelengkap cair (PPC) yang dimulai pada bulan April 2001. Ixikasi percobaan di Desa Sedayu, Sapuran, Kab. Wonosobo pada jenis tanah latosol coklat dan tipe iklim Bl Tujuan penelitian untuk mengctahui/mempelajai pengaruh /.PT dan PPC serta kombinasinya dalam memacu pertumbuhan vegetatif klon Pujon 10 dan Jawa Timur. Perlakuan disusun secara faktorial dalam rancangan petak terbagi dengan tiga ulangan Perlakuan petak utama terdiri atas macam klon rami. yaitu Pujon 10 dan Jawa Timur, sedangkan anak petak berupa pembeian ZPT, PPC. dan ZPT ' PPC tcrdii atas scmbilan macam yang meliputi : (1) 60 N + 20 P,Oj * 60 KjO ' 10 ton pupuk kandang sapi, (2) 60 N • 20 P20, • 60 KjO - 10 ton pupuk kandang sapi • ZPT 1 (kons 1 ml/1), (3) 60 N • 20 PjO, + 60 K20 > 10 ton pupuk kandang sapi • ZPT 2 (0 5 ml/I); (4) 60 N * 20 P20, ♦ 60 KjO ♦ 10 ton pupuk kandang sapi * PPC 1 (3 g/l); (5) 60 N • 20 P20, - 60 K20 t 10 ton pupuk kandang sapi • PPC 2 (0.65 gl); (6) 60 N < 20 P205 + 60 K20 + 10 ton pupuk kandang sapi ♦ ZPT 1 + PPC I, (7) 60 N + 20 P2Os + 60 K20 r 10 ton pupuk kandang sapi t ZPT1 + PPC 2, (8) 60 N - 20 P2O5 * 60 KjO 1 10 ion pupuk kandang sapi + ZPT 2 + PPC 1 dan, (9) 60 N + 20 P2Oj + 60 K20 t 10 ton pupuk kandang sapi + ZPT 2 l- PPC 2.
