Formation of highly productive agrophytocenoses of <i>Raphanus sativus</i> L. subsp. <i>acanthiformis</i> (Blanch.) Stankev. in the conditions of the North Caucasus

Abstract

Relevance. One of the most important tasks of agricultural production is to provide the population of the regions with vegetables at the expense of local production. Despite the social significance of the vegetable growing industry, its development in the Central Ciscaucasia at the present stage allows only half to meet the demand of the population. For the Chechen Republic, where the area of arable land is limited, the daikon (Raphanus sativus L. subsp. acanthiformis (Blanch.) Stankev.) Has a certain perspective, especially for cultivation in the summer-autumn period, after early harvesting of vegetables and field crops.Results. Under the conditions of the Chechen Republic, the maximum yield of root crops (29.0 t/ha) and marketability of 65% of the early maturing variety Sasha was obtained with a sowing time of 31.07 and a scheme of 35x10 cm. The highest yield of root crops of varieties Dubinushka, Dragon, Favorit was formed at a sowing time of 17.07 (58.1, 62.3 and 57.3 t/ha, respectively), and variety Moskovsky Bogatyr – at a sowing time of 3.07 (72.3 t/ha) at sowing scheme 70x10 cm.
