Selection of the right seed according to the area
The first point to achieve a good yield of potatoes is to prepare suitable seeds and favorable storage conditions in such a way that you avoid preparing seeds that have germinated or are damaged (seeds containing broken sprouts, weak and many stems) because this The type of damaged seeds is associated with physiological aging and increases the risk of diseases.
To maintain the health of the seeds, it is essential that potato residues are not located around the seed storage warehouse because they are a source of disease. Another thing that you should pay attention to is that the place where the seeds are stored should have ideal ventilation and humidity, and the potato seeds should not be exposed to light and temperature fluctuations.
Seeding gland size
One of the effective factors in potato yield is the size and age of seed tubers. Normally, seed tubers weighing 35 to 80 grams are used to produce potatoes, but the use of smaller and larger seed tubers is also common in some regions.
The amount of seed required per hectare
The amount of tubers for planting edible potatoes is different from seeds. In order to plant edible potatoes, if seed tubers with an average weight of 50 grams are used and the planting distances are 30 x 75 cm, 2.2 tons of seed tubers of the mentioned size will be needed. In seed farms, the amount of seed consumption per hectare is higher.
Preparation of seeds
An important point in the preparation of tubers is to break the apical dominance of the tubers, which has a significant effect on the number of stems and then the yield.
The tubers should be taken out of the cold storage 3 weeks before planting. and spread in a dark room. At the time of spreading, its primary buds must be cut or broken to activate other potato buds, each bud is responsible for producing a stem, and the increase of the stem is directly related to the increase in the number of tubers.
Another one. One of the things you should pay attention to is that the tubers should be disinfected at the time of planting, which can be done using fungicides or sodium hypochlorite solution (Vitex 5% active chlorine). For this purpose, 3 to 5 liters of sodium hypochlorite per thousand liters of water can be used, which is considered as one of the cheapest and best methods of seed disinfection. On the other hand, it should be prevented from spilling the disinfectant solution of one gland on another gland.
Choosing the right farm
Each farm has characteristics that should be considered by dear producers, among these characteristics, physical and chemical characteristics of the soil, tillage methods, history of crop rotation, pest problems of previous crops, and production costs can be mentioned.
< Potato fields in the best conditions have deep soil, proper drainage and storage capacity, low to medium slope and low concentration of sodium and soluble salts. Planting history is another important thing that you must consider, so that it is better that potatoes or plants of the same family as this product have not been planted in the land in question for at least 3 to 5 years.
