Peanuts in the northern hemisphere is harvested in July to September each year; while in the southern hemisphere is harvested from January to March.

Criteria for Peanut Maturity

I. The harvesting date of peanuts should be based on the plant's looks and the maturity of the pods.

Peanuts into the harvest period, the plant, stalks and leaves, there are obvious changes, from the plant looks, the upper leaves open day and night sensory night movement is not sensitive or disappeared, the middle and lower leaves from the green to yellow and gradually fall off, the stalks turn yellowish-green and withered and soft, the plant from the compact to loose, and there is a tendency to fall over, at this time for the best harvest period.

Second, the maturity of the pods to determine the harvest period

Small-fruited early varieties of full fruit rate of 75% or more, intermediate varieties of full-fruit rate of 65% or more, ordinary varieties of full-fruit rate of 45% or more of the late varieties of full-fruit rate of 45% or more, pods hardening of the husk, the majority of pods of the webbing is obvious, the spongy layer of the internal pods to shrink the rupture and have a black-brown luster, seed kernel fullness. Dark brown luster, seed kernel full, seed coat showing the inherent color, we must seize the harvest, harvest late drop fruit more, picking difficulties, yield reduction, quality deterioration.

Three, different situations to take different harvest

Generally the first early varieties and barren plots, late varieties and late varieties and fertilizer plots. The pods harvested when the soil is wet than dry pods harvested when the germination rate is high, stay with the seed peanuts, to be harvested earlier than the general use of peanuts, harvested at the right time of the peanut, the inner membrane of the husk is white, the seed is strong life.
