Due to the differences of peanut varieties, growth period, planting time and regional climate, the suitable harvesting period cannot be generalized. Peanut is a ground flowering, underground fruiting crop. The growers should determine the best harvest time, timely drying based on the ecological habits of peanuts to improve the marketability of peanuts. Based on our practical experience with the fall harvest, we usually make judgments based on the appearance of the peanut plant, the development of its pods, and local climate change.
