Preparation of the seeds:
The seeds have to be peeled shortly before sowing, because without the shell or shell it is a very delicate seed. After being peeled these grains are subjected to treatment with insecticides and fungicides, which will protect them in the storage and germination period. Once the treatment process has been completed, they should be planted as soon as possible and avoid contact with the light.

Sowing of peanuts:
Before proceeding with the sowing of peanuts, we must consider the following:

a) Prepare the soil: The preparation of the soil depends on the areas where the cultivation will take place, it must take into account the conditioning of the soils in order to facilitate the absorption of water and root.

b) Sowing period: it is established according to the vegetative cycle of the peanut plant. It must be sown in the most favorable period according to the climatic conditions.

c) Seeding density: the amount of seeds that we plant per hectare must be taken into consideration. It should be taken into account or estimate a percentage of germinated seeds. The late varieties should be planted more or less 120000 seeds per hectare. Early varieties can be planted with high density (between 170000 and 190000 seeds per hectare).

d) Way of sowing:The depth of the hole should not exceed 5 cm, although the optimum depth is 3 cm, as long as the earth has enough moisture. For the sowing of these seeds it is recommended that they be planted in the form of rows and in this way the maintenance of the crop is facilitated. For late varieties, these measures will be used in their separation of 0.60 m between the rows by 0.15 m on the row. In the early varieties it is advisable to use 0.40 m between the rows and 0.15 m above the row. It is also advisable to place a grain in each hole, since with more grains there is no increase in yield, because in case one of the grains does not germinate the other one may be affected.

Nutritional requirements:
These plants absorb mineral elements through soil solutions, their roots and their gynophores. The gynophores participate in the absorption of calcium. Among the main nutritional requirements we have:

1.-Nitrogen: this plant, due to its legume characteristic, peanuts are nourished by a certain quantity of nitrogen from the atmosphere, through the "Rhizobium". Nitrogen is essential for peanuts, which it contains in high amounts, not only in the foliage but in the grains (proteins).
Phosphorus: its presence in peanuts is scarce. This plant has an absorption power of phosphorus in soils that do not have or are poor of this component. Phosphorus has the peculiarity of activating growth and accelerating its maturation. The plant without this element is shown in a normal way, then the growth decreases and surprisingly the plants die.

2.-Potassium: This element can be absorbed by plants in large quantities if they are located in sites rich in K20. The lack of potassium in the plants usually cause the pods to be produced abundantly but from a single grain, in addition to when the vegetation starts, the plants usually have a tough appearance with darker leaves, but then the growth of the plant decreases. plant and the leaves are affected by necrosis and discoloration.

3.-Calcium:It must be supplied to the plant in high quantities since it is fundamental in the formation of peanut kernels between the first 30 to 100 days of planting. It must be applied in a soluble form in such a way that it is easily absorbed. During the process of fruiting when you need to apply calcium in high doses. These plants usually produce calcium through the roots, gynophores and covers in formation. The absence of calcium does not allow the pod to be filled causing fragility and decrease in the fertility index of the flowers.
