In the present study, lichen(Parmelia sp.) extract showed insecticidal activity against Aedes albopictus, and the effect of growth inhibiting activity was investigated. Acetone and methanol extracts of the lichen against larvae of Aedes albopictus were showed high insecticidal activities in low lethal concentration. 50% lethal concentration of the acetone extractof the lichen is 0.13% and the 50% lethal concentration of methanol extract of lichen is 0.15% respectively. This experiment that used acetone and methanol extracts of the lichen were observed for 24, 48 and 72 hours. As a result, the higher concentration and the longer exposure time is increased mortality against Aedes albopictus. Pupation time took more time as the higher concentration of acetone extract of lichen. Consequently, the lichen extract is effect in inhibiting the growth of Aedes albopictus larvae. In this experiment indicates that lichen extract has activity against Aedes albopictus and is available as the natural insecticide.

Background : The purpose of this study was to evaluate methods to high quality food ramie rice cake, thereby increasing farm income. This study investigated the effects of different Split Application and Adapted Fertilizer Culture for Stable Production with Edible Leaf in Ramie (Boehmeria nivea L.). Methods and Results : Method of fertilizer application were conducted under three condition compose to standard application (N-P-K-Compost applied at 27-9-27-1,500 ㎏․ 10 a−1), 25% increased application (N-P-K-Compost applied at 34-11-34-1,500 ㎏․10 a−1), 50% increased application (N-P-K-Compost applied at 41-14-41-1,500 ㎏․ 10 a−1) cultivation. Compost and fused phosphate applied at 100% of basal fertilizer in March 25. The split application level of standard application (N-K) applied at 50% of basal fertilizer in March 25, 50% of top dressing were five times application (N-K) in May 4, July 5, September 5, October 5, 20% respectively. Transplanting with Yeongkwang varieties in April 12 by growing pot seedling for 35 days in 2011. Planting density were spaced 60 ㎝ apart in rows 25 ㎝ apart with rice straw cutting covered open cultivation. Plot design randomized block 3 repetition. Conclusion : Organic matter, available phosphate, K2O, CaO, and MgO of soil increased in all plots with the addition of fertilizers culture, specifically in 25% and 50% increased application. Growth characteristics by 50% of top dressing were five times application (N-K) in May 4, July 5, September 5, October 5, compared to standard application (N-K) applied at 100% basal fertilizer, aerial part as a result were so many such amount of growth as number of branch and leaf per plant, etc., Length, width of leaf and leaf colorimetry of aboveground part growth increment rising highest. Green leaf yields compared to standard fertilizer 100% application (1,344 kg․ 10 a−1). 25% and 50% increased application (N-K) applied at 50% basal fertilizer, 50% of top dressing were five times application increased by 9%, 17%. respectively.

A new sprout-soybean cultivar, "Jonam" was developed at the Honam Agricultural Research Institute (HARI) in 2006. Jonam was selected from a cross between Eunhakong and Jeonju-I1. The preliminary, advanced, and regional yield trials for evaluation and selection of this line (Iksan 48) were carried out from 2002 to 2006. This cultivar has a determinate growth habit with purple flower, grayish brown pubescence, grayish brown hilum, lanceolate leaflet shape and small seed size (9.6 grams per 100 seeds). The maturity date of "Jonam" is 18 days earlier than that of the check variety, "Pungsan". It has good seed quality for soybean-sprout and resistance to lodging. This cultivar has resistance to soybean mosaic virus (SMV) and necrotic symptom(SMV-N). The average yield of "Jonam" was 2.57 ton per hectare in the regional yield trials for double cropping carried out for three years from 2004 to 2006.
