The growth environment and characteristics of yam

Yam growth environment conditions and requirements

Yam, also known as Dioscorea, is widely distributed in my country. It is mostly found on hillsides, valleys, stream banks and other locations below 1,500 meters above sea level. The plant prefers a warm, humid, well-lit growing environment and is a short-day crop.

Yam growth temperature

The optimum growth temperature of yam is 25-28℃, and the temperature during the seedling stage must be above 15℃. The plant's cold resistance is very poor, and the plant will grow slowly when the temperature is below 20℃.

Yam growth humidity

Yam does not require much water. The plant is relatively drought-resistant, but not water-resistant. It is not suitable to be planted in too moist soil. The soil moisture content should be around 18%.

Yam growing soil

Yam prefers loose, fertile, deep soil, but it has strong adaptability to soil and can grow normally in heavier soil.

Yam growth cycle and process

The growth cycle of the yam plant is about 180 days. The plant's growth will go through several stages including germination, tuber expansion, dormancy, etc. The seedlings can grow to about one meter within 7-10 days after emerging from the soil. The tuber expansion period can last for 60-80 days and it can be harvested in October-November.
