Growth and yield of young ginger on humic and manure media

Английский. Humic substance and cattle manure source of organic matter in soil media have positive effect on chemical, physical, and biological soil properties for plant growth and productivity. The aim of this research was to study the influence of humic and cattle manure application on the growth and productivity of young ginger. The research was conducted in pot experiment, at Cimanggu Research Instalation since January to May 1996. A randomized block design was used with three replications. The treatments were (1) control (k), (2) humic media without using anorganic fertilizer 1.70 kg/polybag (h1), (3) 3.30 kg/polybag (h2), (4) 5.00 kg/polybag (h3), (5) 6.70 kg/polybag (h4), (6) cow dung 0.50 kg/polybag (p1), (7) 0.75 kg/polybag (p2), and (8) 1.00 kg/polybag (p3). The results showed that the application of treatments affected significantly on the growth of young ginger (the height/clump, the amount of tillers and leaves per clump) and the yield of young ginger rhizome. The highest yield of young ginger rhizome was 663.04 g/clump at humic media treatment 6.70 kg/polybag. The percentage of fiber and the extract content solution in alcohol of young ginger were 12.37 and 9.02 percent at 6.70 kg humic/polybag, meanwhile 11.06 and 9.53 percent at 1.00 kg manure/polybag combined with urea, TSP, and KCl fertilizer

Humus dan pupuk kandang merupakan sumber bahan organik dalam media tanah yang dapat memberikan dampak positif terhadap sifat kimia, fisik, dan biologi tanah dalam menunjang pertumbuhan dan produktivitas tanaman. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan humus dan pupuk kandang terhadap pertumbuhan dan produksi jahe muda. Penelitian ini merupakan percobaan pot, yang dilakukan di Instansi Penelitian Cimanggu, Bogor, dari bulan Januari sampai Mei 1996. Penelitian disusun dalam rancangan acak kelompok dengan tiga kali ulangan. Perlakuan yang diuji meliputi: (1) media tanah tanpa penambahan humus dan pupuk kandang (kontrol), (2) 1.70 kg humus/polybag (h1), (3) 3.30 kg humus/polybag (h2), (4) 5.00 kg humus/polybag (h3), (5) 6.70 kg humus/polybag (h4), (6) pemberian pupuk kandang 0.50 kg/polybag (p1), (7) 0.75 kg/polybag (p2), dan (8) 1.00 kg/polybag (p3). Hasil penelitian menunjukkan bahwa pengaruh perlakuan nyata terhadap pertumbuhan (tinggi rumpun, jumlah anakan/rumpun, dan jumlah daun/rumpun) maupun produksi rimpang jahe muda. Penggunaan 6.70 kg humus/polybag memberikan produksi jahe muda tertinggi, yaitu 663.04 g/rumpun. Kadar serat dan kadar sari dalam alkohol masing-masing adalah 12.37 dan 9.20 persen untuk perlakuan 6.70 kg humus/polybag, serta 11.06 dan 9.53 persen untuk perlakuan 1.00 kg pupuk kandang/polybag yang dikombinasikan dengan urea, TSP, dan KCl
