Information and analytical technologies in two-crop potato cultivation

Research conducted in the Moscow region over two growing seasons revealed that potato yield development occurs under different agroclimatic conditions. The first wave of harvest occurs during a period oflong daylight hours at moderate temperatures, accompanied by possible recurrent frosts. The second wave of ripening occurs during a period of shortened daylight hours, when elevated air temperatures and soil moisture deficits are observed. The main objective ofthe study was to determine the potential ofthe domestic Loginom analytical platform for the informed selection of potato varieties optimal for double cultivation, depending on weather factors. Experimental trials were conducted at the Vegetable Experimental Station Educational, Scientific, and Production Center ofthe Russian State Agrarian University – Moscow Agricultural Academy named after K.A. The experiment was conducted at the Timiryazev Research Institute (Moscow) and atthe Central Experimental Station ofthe All-Russian Research Institute of Agrochemistry (Barybino, Moscow Region) from 2017 to 2023. The trial was conducted using random plot placement, with onions being the preceding crop. The planting density was 47,600 plants per hectare. Sprouted tubers ofthe large fraction were used for the first planting, while medium-sized ones were used for the second. Replanting was carried out in areas vacated after harvesting the first crop. Cultivation practices complied with generally accepted standards. The crop was harvested twice: in mid-July and at the end of September. An information and analytical decision support system was used to select the most productive potato varieties for critical climatic conditions. Based on the forecast results, it was determined that for obtaining an early harvest, it is advisable to use the varieties Zhukovsky ranniy (early), Snegir, Red Scarlet, Riviera and Impala, and for the second cultivation cycle, the varieties Udacha, Red Scarlet and Impala showed the greatest efficiency.
