 Abstract
This experiment was carried out to figure out the growth and yield of waxy corn after cultivating the hairy vetch which was mostly used as a green manure crop. The waxy corn showed the growth and yield efficiency relative to conventional culture after the hairy vetch was returned to as the green manure and the amount of nitrogen fertilizer increased, and the LAI was similar to the conventional culture when less than 18 kg. Length of ear slightly decreased compared to 188 mm of conventional culture when the hairy vetch was used as the green manure and the amount of nitrogen fertilizer was less than 9 kg, but the length of ear increased relative to the conventional culture when the amount of applied nitrogen fertilizer was more than 18 kg. The highest 100-kernel weight was 35.4 g with the hairy vetch and 27 kg of nitrogen fertilizer treatment. The lowest 100-kernel weight was 27.4 g with the hairy vetch and 0 kg of nitrogen fertilizer treatment. Quantity with the hairy vetch and 9 kg of the nitrogen fertilizer treatment was similar the conventional culture. Suger content with the hairy vetch and more than 18 kg of the nitrogen fertilizer treatment was higher than the conventional culture. Thickness of pericarp showed no difference among treatments.
