Research on raising income of upland crops

Performance

1. Technology development for raising income using agricultural products of upland crops

• Effects of no-tillage cultivation on fresh corn: labor saving by 18% and yield increase by 11%
• Use of non-woven fabric in early cultivation of sweet potato: labor saving by 32% and yield increase by 45%
• Nursery seedling of Korean native tea plant : compare with the conventional method cup pot ￠ 16cm is reduced cost for making tea farm by 50%
• Optimum planting date and method for broad bean : conventional method Mar. 10, seedling transplanting Feb. 25

2. Dual using of forage and grain by cutting before winter in barley

• Cultivation system: Seeding(late September) - Using fresh forage (two times, November and December) - grain harvest(June)
• Selection of adaptive barley varieties: Kunalbori, Daebackbori, and Saegangbori, those having middle winter habit

3. Improving the method of fertilizer application for nitrogen fertilizer to enhance the quality of malting barley

• Application time : middle February
• Application rates of top-dressing : 25%
• Effects: decreasing protein by 4% and increasing yield by 8%

4. Development of labor saving cultivation technology for stable yield production in barley

• Mechanized and least input cultivation technology : waxy barley and inter-cropping with cover plants
• Research on the agricultural technologies donating to North Korea:Selecting barley adaptive to spring-time seeding and cropping system
• Constructing a model field for labor saving cultivation: 130 ha in 13 locations.

5. Improvement of land use by multiple cropping system

• Establishing proper planting patterns with multiple cropping and high income: 5 patterns with barley and soybean, etc.
• Research on problems occurring at household: Improving the fruiting of soybean and reducing damages on direct-sown crops by birds
• Developing environment-friendly agricultural technology for edible corn: no-tillage and raising crops for green manure out-season
