PENGARUH KELEMBABAN TANAH TERHADAP KARAKTER AGRONOMI, HASIL RAJANGAN KERING DAN KADAR NIKOTIN TEMBAKAU (Nicotiana tabacum L; Solanaceae) TEMANGGUNG PADA TIGA JENIS TANAH
Abstract: Research on the
effect of soil moisture on agronomic characters, yield and nicotine content of
Temanggung tobacco has been conducted in the Research Institute for Tobacco and
Fibre Crops at Malang, East Java from March to October 2010. The treatment has
been arranged in a Splitplot design with 3 replications. The experimental plot
consisted of three types of soil: Complex Eutrudepts-Hapludalfs, Vitraquands,
and Complex Dystrudepts-Hapludalfs. The subplot comprised 5 levels of soil
moisturation: 60, 70, 80, 90, and 100% of field capacities. The results showed
that the dry slice yield, content of nicotine, and agronomic characters of the
Temanggung tobacco were affected by the result of interaction between soil moisture
and type. The decreasing of soil moisture up to 40% from field capacity in the
Complex Eutrudepts- Hapludalfs had decreased dry slice yield, nicotine content,
plant height, root length, dry weight of plant, shoots, roots, stems, leaves,
flowers, and suckers accounted for 54.3, 19.3, 33.7, 17.1, 74.1, 71.4, 82.3,
80.1, 54.3, 60.5 and 86.5% respectively, in the Vitraquands 72.7,20.2, 37.0,
13.2, 79.8, 78.5, 84.3, 80.7, 72.7, 63.3 and 87.8% respectively, and in the
Complex Dystrudepts-Hapludalfs 74.2, 23.0, 39.6, 15.7, 79.3, 78.0, 83.6, 80.3,
74.2, 79.1 and 80.6% respectively.
