When is the best time to harvest peanuts? (What month is the best time to harvest peanuts?)

Crops are something that makes people anxious when they are not ripe at the harvest season. But you can't harvest them when they are not ripe, right?

For crops like peanuts, since they bloom and bear fruit successively, the fruits on the same peanut vine mature at different times. Some fruits mature in the fall, while others mature in the summer. If harvested too early, some fruits are not mature and full, contain too much water, and become barren grains after drying, which directly affects the yield.

If the harvest is too late, the pods will easily fall to the ground and be eaten by underground pests such as white grubs. Once there is heavy rain, the fruits will easily rot or even sprout underground.

This year, most of the peanuts were ripe here in early August of the lunar calendar, but the weather was not good. It rained all day for nearly 10 days, causing the peanuts in the depressions to rot and germinate.

When is the best time to harvest peanuts?

The harvest time of peanuts should be determined based on the growth and appearance of the plants, the development of the pods and the local temperature changes. This is a general principle.

1. Plant growth and appearance

When the top of the peanut plant no longer grows, most of the leaves in the middle and lower parts fall off, the top leaves turn yellow, the stems turn yellow-green, and in the evening, the leaves no longer close, it means that it is time for your peanuts to emerge from the ground.

I usually stand at the edge of the field and can see the plastic film and the ridges. The leaves on the peanut vines are dry and sparse. If I take a closer look in the field, I can see that there are only a few leaves on the top of a peanut vine. That's when it's time to take action.

2. Development of pods

Pull out a few peanut plants from the field. More than half (over 80%) of the peanuts have clear lines. Peel off the shells and you will see that the kernels inside are full and the seed coat is pink (or has the inherent color of the variety) instead of white. This indicates that they are ripe.

If most of the husk is white, the lines are not clear, the endocarp is white and does not turn black, the seed coat is white, and the kernel is tender, then it is not ripe and it will take a few more days.

3. Local climate change

Some people delay sowing for various reasons, or due to the region, sowing season (such as peanuts on wheat stubble), etc., when it is time to harvest peanuts, they are not mature. It depends on the changes in temperature.

Peanuts are thermophilic crops. When the average day and night temperature drops to 12℃, the peanut pods will stop developing and no longer grow. At this time, you should pull them out even if they are not mature. Otherwise, if it is too late, they will be in danger of frost damage.

Whether the peanuts are ripe does not only depend on the season, but also on their growth, fruit, temperature, and variety.

Why do peanuts grown by two different families on the same plot of land mature at different times?

This is mainly related to the variety. Generally speaking, the late-maturing peanuts sown in the northern region have a long growth period and mature late. If they are sown at the right time, they can usually be harvested before October 20 .

Some mid-maturing and early-maturing varieties can generally be harvested in mid- to late September if sown at the right time.

Of course, peanuts planted under plastic film covering will mature earlier due to the earlier sowing time, and the harvest time will also be advanced accordingly, by about a month.

If there is too much fertilizer, especially nitrogen fertilizer and organic fertilizer, the harvest will be delayed. Lao Liu's peanut field has been planted with ginger for many years, so there is enough material in the ground, which delays the maturity time and the harvest time will be a few days later.

For plots where disease control is not thorough, the leaves fall earlier and the unripe fruits should be harvested, otherwise they will fall and sprout. For plots where grubs are heavily infested, they should also be harvested early, otherwise they will be bitten and fall, rot and sprout.

The weather here has been sunny these days. With the arrival of the autumn heat, the temperature at noon has reached over 30℃, and the streets and alleys are full of peanuts drying in the sun.

But the colors are different, some are black, some are yellow and white, and some are colorless, because the pods are wrapped in mud. Although they have been unearthed, they have not yet "unearthed".

But the price is still good this year. Some people buy peanuts that have just been dried for one day, and the price is about 2.50 yuan. After drying for three days, the price is about 3 yuan per catty. What is the price of peanuts in your area?
