Gold rush corn is a super sweet corn that is easy to eat for children and elderly people because the skin of the grain is very soft and it is hard to get caught in the gaps between teeth, and it is gaining popularity from consumers. The golden grain, which is the origin of the name, is densely packed with fruits and has a sweet and fresh texture.
A yellow variety with an extremely soft grain skin and a refreshing sweetness. The ripening period is 83 to 84 days, and this type has a fairly early growth, and it seems that the 2L size can be harvested stably. Since it has good germination and low temperature elongation, it seems that it can be cultivated stably from early cropping such as tunnel cultivation. Gold rush ripens faster after pollination than conventional varieties, so it seems that the tip is a little immature and the best time to harvest.
Sweet corn is a crop with relatively wide adaptability, and it does not choose the field so much, but it maintains a healthy field with drainage, water retention, and fertilizer retention by applying manure and green manure. The standard fertilizer is 25 kg per 10 a for nitrogen, phosphoric acid, and potassium. For nitrogen content, 1/2 is applied as the main fertilizer and the remaining 1/2 is applied as the top fertilizer. The planting density varies depending on the region and cultivation type, but it seems that 4,200 plants per 10 a (ridges 80 to 90 cm, plants 27 to 30 cm) are a guide. To improve the germination, ensure that the soil temperature is 15 ° C or higher, and then sow 3 grains per hole. It seems that caution is required because not only temperature but also moderate soil moisture affects germination.
