SKRIPSI PENGARUH KONSENTRASI DAN LAMA PERENDAMAN BIBIT DALAM LARUTAN AGRIMYCIN TERHADAP SERANGAN PENYAKIT LAYU BAKTERI PADA TANAMAN JAHE (Zingiber officinale Rosc.) VARIETAS GAJAH
ABSTRACT
An experimental concering the effect of Agrimycin con- centration and soaking duration to the attack disease wi- thered was carried out in 8 Oktober 1993 until 28 February 1994. This experimen was carried out at Kedungsari village, Magelang, central Java. The kind of soil is latosol, moil pH 6.5 with an altitude of 380 m above sea level. The purpose of this research is to know the effect of Agrinycin concentration in combination with soaking durati- on to the attack disease wilt bacterium.
The experiment was arranged with randomized Completely Blok Design (RCBD), arranged in factorial, with two factors and three replications with analysis P table at 5 % and 1 % and than Duncan Multiple Range Test at 5%. Factor I Concentration Agrimycin (K) consist of 4 level, they are: without treatment 1 : concentration 0,05 N concentration 0,1 % 23 concentration 0,15 N Pactor II: Soaking duartion (T) consist of 4 level, they 15 minute 123 : 25 minute :35 minute The result showed that: 1. The treatment Agrimycin concentration gave a very signi- ficant offect for all observation parameters (intensity of attack, weight of attack, number of tiller, fresh weight of rhizome, fresh weight of straw, dry weight of straw). 2. The treatment noaking duration gave very significant ef- fect to intensity of attack, weight of attack, fresh weight of straw and a significant affect to the dry weight of straw. Prom all observation parameters, there was no interac- tion between Agrimycin concentration an soaking duration.
