How exactly is the sesame emergence stage divided?

(Agricultural Wealth Network) From the time the seed is planted in the soil until the embryo breaks through the surface and the cotyledons open, this is generally called the emergence stage. The length of this stage depends on soil temperature, soil moisture, and rainy or overcast weather. Under normal conditions, it takes 5 to 7 days for spring sowing, 4 to 5 days for summer sowing, and 3 to 4 days for autumn sowing.
