Under the conditions of Novosibirsk rural district 3 regionalized early radish varieties (Ilke, Igorek, Krasa Altaya) were studied in the open ground with early sowing dates and cultivating them in the inter-rows of primary vegetable crops: pea, bean, carrot, parsley, celery, parsnip, bulb onion out of seeds, bulb onion out of onion sets. Weather conditions of the years 2012 and 2013 largely differed from the ones averaged over multiyear data. All the vegetable crops were sown and planted in the same day of the both years. Radishes were harvested and the productivity was recorded in 3 steps: two selected harvests and one terminal, the rest of the vegetable crops was harvested with solid method when the ripeness required was reached. The best primary crops for radish production as an inter-row crop were: bulb onion out of seeds, bulb onion out of onion sets, pea and bean. Radish productivity when grown in inter-rows of these vegetable crops was 15-20 % higher than when grown in the inter-rows of carrot, parsley, celery and parsnip. The most productive radish varieties turned out to be Ilke and Krasota Altaya. The variety Igorek was less productive in the both years of examination.
