Peanut Planting with Shells: Methods and Benefits, High Yields with Scientific Fertilization

Peanut is a crop that farmers plant every year. It is not only easy to grow and highly versatile, but also rich in nutritional value. The peanuts we usually see are generally planted after shelling. Today, the editor will talk about planting peanuts without shelling. So, can peanuts be planted with shells? How to plant them? What are the benefits? What fertilizer gives high yields?

1. Can peanuts be planted with shells? How to plant them?

Peanuts can be planted with shells, and this can increase yield by 5%-20% compared with shelled planting.

1. Seed treatment. Mainly choose early-to-mid-maturing varieties, and sun-dry the pods for 2-3 days before sowing. Break double-kernel pods into single-kernel pods, and pinch open the tip of single-kernel pods to help the kernels absorb water and emerge. Soak the pods in warm water at 35°C for 6-8 hours, remove and drain the water, and then sow.

2. Sow early at the right time. This method should be carried out 20 days earlier than the local conventional sowing period. If sowing is too late, it will not increase yield. Peanuts planted with shells grow faster at the seedling stage and slower in the middle and late stages, with short plants and short branches and a relatively compact plant shape. The sowing density needs to be increased by 10%-15%, sowing 11,000 hills per 67 sq m (1 mu).

3. Sow appropriately shallowly. This method emerges slowly, so deep sowing is not suitable. The best sowing depth is 3-5 cm. After sowing, gently press with a foot to prevent the shells from being brought out of the soil during emergence. For seedlings that have emerged with shells, remove the shells to avoid affecting seedling growth. To control underground pests, seed dressing with a seed coating agent can be used before sowing, using 1 kg of seed coating agent per 50 kg of seeds. You can also use 100 g of 40% isofenphos-methyl or 50% phoxim, add ± kg, and spread it into the sowing furrow.

4. Strengthen management. After emergence, check the seedling condition and help seedlings emerge from the soil to reduce weak and dead seedlings. During the growth period, combine promotion and control, and prevent and control pests and diseases. If excessive growth occurs at full flowering stage, spray chlormequat at a concentration of 0.1%. When the aphid count reaches 500 per 100 hills, spray omethoate for control.

2. What are the benefits of planting peanuts without shelling?

The main benefits are that the seeds absorb water quickly, emerge quickly, and grow uniformly. At the same time, after shelling, kernel selection can also be carried out to ensure seed quality and improve the emergence rate.

Notes on shelled peanut planting technology:

1. Do not shell too early. If shelled too early, the seeds lose the protection of the shell and easily absorb moisture from the air, enhancing respiration and enzyme activity, promoting material transformation, and consuming a large amount of nutrients, thereby reducing vitality. After sowing, emergence will be slow and uneven. It is best to sun-dry the seeds with shells before sowing, and then shell them.

2. If shelled seeds cannot be sown within a short time, they need to be wrapped well in plastic bags to prevent moisture from affecting the germination rate.

3. What fertilizer should be applied to peanuts for high yields?

Peanuts have broad adaptability to soil, but high-yield peanut fields require good soil conditions. They are best planted in sandy loam soil that is loose on top and firm below, where rain can drain quickly without water accumulation, and drought can be quickly irrigated with fast water penetration. Peanut fertilizer uptake is very small at the seedling stage, but if fertilizer is lacking, it will hinder strong seedling early development and nodule formation.

Fertilization principles: 1. Apply organic fertilizer together with inorganic fertilizer. Combine nitrogen, phosphorus, potassium, and micronutrient fertilizers reasonably, apply sufficient base fertilizer, and topdress appropriately. 2. For topdressing amount, use peanut special fertilizer with 45% content at 25 kg per mu. 3. In the middle and late stages, spray foliar fertilizer according to growth conditions, such as boron and zinc (0.2%) and potassium dihydrogen phosphate (0.1—0.2%), which can protect leaves and roots and extend the functional period of the top leaves.
