Abstract

Kenaf is one of fiber producing plants. According to the existence of branches, kenaf is classified into two group, consisting of: kenaf with branch and with no branch.Morphology observation, consist of the height of plant, the number of node, the number of branch and the length of branch was observed. The morphology observation showed that there were differences morphological characters, including of the height of plant, the number of node, the length of branch, and the number of node more branching kenaf, control non branching (KR11) and control branching (SM004).Non branching plants (KR11) have the highest habitus and smallest number of branch compare to other groups. Control branching (SM004) was the shortest habitus and greatest number of branch compare to other group. The highest of Non branching plants (KR11) 230,6 ± 36,7 cm and the smallest control branching (SM004) 116,3 ± 64,4 cm. The greatest number of branch found in controled branch SM004, with 5,6 ± 2,7 branch in every plant and the smallest is KR11 with 0,8 ± 0,8 branch in every plant.According to this research the length of plant influence the branch. The highest level of auxin were in the shoot tip and the lowest level were in root tip. The higher auxin will produce less branch, the lower auxin will produce more branch.

Abstract

Serangga hama merupakan salah satu faktor pembatas produktivitas kapas berbiji. Pengendalian serangga hama dengan insektisida yang dilakukan dengan penyemprotan pada tanaman (foliar spray) berpengaruh negatif terhadap musuh alami. Perlakuan benih dengan insektsida imidakloprit diharapkan dapat menjadi satu pilihan cara pengendalian serangga hama yang mampu mengkonservasi musuh alami. Tujuan penelitian adalah untuk mengevaluasi pengaruh perlakuan benih dengan insektisida imidakloprit sebagai komponen pengendalian hama pada budidaya kapas varietas seri Kanesia yang baru dilepas (Kanesia 10, Kanesia 11, dan Kanesia 12). Penelitian ini dilaksanakan pada Maret – Oktober 2007 di Desa Jati, Kecamatan Jati, Blora, Jawa Tengah.  Penelitian disusun menggunakan rancangan acak kelompok delapan perlakuan diulang empat kali.  Perlakuan yang dicoba terdiri dari : Kanesia 8 tanpa perlakuan benih (varietas pembanding);   Kanesia 8 dengan perlakuan benih;  Kanesia 10 tanpa perlakuan benih;  Kanesia 10 dengan perlakuan benih; Kanesia 11 tanpa perlakuan benih; Kanesia 11 dengan perlakuan benih;  Kanesia 12 tanpa perlakuan benih; Kanesia 12 dengan perlakuan benih.  Perlakuan benih (=Seedtreatment) menggunakan insektisida benih imidakloprit dosis 2 g/kg benih kapas. Hasil penelitian menunjukkan bahwa perlakuan benih dengan insektisida imidakloprit dapat menekan populasi A. biguttula dan kerusakan yang disebabkannya, tidak berpengaruh terhadap kelimpahan populasi kompleks predator (Coccinellid, P. fasciatus, laba-laba, semut, kepik mirid), dan meningkatan pendapatan usahatani kapas varietas seri Kanesia 10, 11, dan 12.  Perlakuan benih dengan imidakloprit dapat menekan terjadinya aplikasi penyemprotan insektisida, sehingga predator terkonservasi dan dapat menekan populasi penggerek buah kapas H. armigera.

Abstract

Teak Forest Management in Indonesia began at period of Governance of Dutch Colonialism in1860. After independence of Indonesia in 1945, teak forest was managed by Department of Forestry and now was managed by Perum Perhutani. During that time  have been applied by various approach of management which relate to sustainable principles, but with existence of ecosystem change, degradation of indication resource and productivity that teak forest was not managed to sustainable principles. On the other side, commerce of world wood claim the quality of wood coming from managed forest on sustainability principles. This research aim to studying erosion at various of trees age and nutrient loss. Result of research showed that increasing of crop age was degrade the erosion. Soil lose affects of erosion could bring consequence to losing of soil nutrition. Mean losing of soil nutrition per hectare at various teak plants age is : ( 13,8 - 74,3) kg of N; ( 8,7 - 36,2) kg of P; ( 7,2 - 35,2) kg of K; ( 54,6 - 219,2) kg of Ca and ( 7,2 - 28,2) kg of Mg.
