How can we get profit twice time in a year from potatoes?

The harvest of potatoes planted for spring sowing occurs in June-August. Storing potatoes for the remaining 9 months requires additional costs and special conditions. During storage, a large part of the product deteriorates and loses its marketability. This also applies to seed potatoes.

Therefore, when harvesting potatoes twice a year (June-August and October-November), the problem of over-storage of potatoes is eliminated - no special warehouses are required, and the product from summer crops is a very valuable seed material. Thus, potatoes harvested in November are spread in warehouses. It spends a period of rest (yarovization) in December-January and is ready for spring planting in February. There is no need to allocate additional land for summer planting of potatoes. Many farmers do not use the land after harvesting spring crops (grain, other cereals). These lands are plowed in July and are ready for summer planting of potatoes in the second decade of August. Thus, in the irrigated regions of the country, it is possible to create an abundance of potatoes through the efficient use of land, by allocating additional land, and our farmers can use this opportunity to bring additional income to their budgets.

Application of technology: The best predecessors for the potato crop are cereals, legumes, melons and vegetables and peaceful soils. Spring sowing - the land should be plowed in autumn, in January the second plowing should be carried out at a depth of 20-25 cm with 20 tons of manure per hectare. In mid-February, the fields are plowed and prepared for planting. The optimal sowing period is the 3rd decade of February and the 1st decade of March, depending on soil and climatic conditions. Marabella, Agri, Solara from Dutch and German varieties with good productivity indicators, widely used in the republic in recent years as seed material from potato varieties. Impala, Condor, Spunta, etc. is known to be recommended for use. Sowing should be carried out by hand at a rate of 70-30 cm, potato planting at a rate of 75-25 cm, and 50-55 thousand potato tubers should be placed per hectare. Since potato tubers form in the trunk at the top of the root system (potato tubers are a deformed form of the trunk), the bottom should be filled as soon as the first seedlings emerge from the soil. Irrigation should be carried out 3-5 times depending on weather conditions, and the length of irrigation furrows should be 30-25-30 cm from 40 meters. Disease control should be carried out prophylactically for the first time when 3-5 leaves are formed, for the second time during the budding phase, against pests (Colorado potato beetle) when the first insects appear on the leaves. Both disease and pests must be constantly monitored until the leaves begin to turn yellow. The best soils for summer sowing are the areas under the grain. As soon as the grain harvest is over, in July, the fields should be plowed to a depth of 25-30 cm with 20 tons of manure per hectare, and in late July, the fields should be discarded and made ready for planting. Summer planting should not be a problem, especially in areas with water supply. The optimal sowing period is the second decade of August. All agro-technical maintenance work should be carried out as in the spring sowing. If these agro-technical measures are implemented in optimal terms, farmers engaged in potato growing can produce 25-30 tons of potatoes from spring sowing and 15-20 tons from summer sowing.
