• • • Evaluation of promising lines of hungarian sainfoin (Оnobrychis arenaria) to be cultivated in the Dagestan arid area
This report deals with ecological and biological parameters of hungarian sainfoin in the arid zone of Dagestan. The research aimed at selection of the most productive lines to be grown on sandy soil to increase productivity of forage lands. Experiments took place on the “Nogayles” trial field in 2013–2017 and studied nine dry-steppe lines of hungarian sainfoin. Working plan comprised monitoring of plant growth, phytomass accumulation, green mass, hay and seed productivity as well as resistance to pests and diseases. Selected genotype (K-1251) had the highest single-plant mass of 262 g, exceeding other lines by 8–58 g. This was the result from increase in stem number up to 34 pcs. per one plant, including generative shoots — 29 pcs. K-1251 surpassed other genotypes in inflorescence length, flower and internode numbers. The best seeding rate of K-1251 was 40 kg ha-1, providing the highest green mass yield — 40 t ha-1. Nodule quantity made up 185–200 pcs. per one plant and their weight — 2.1–3.1 g. Crop harvesting happened from the early flowering to mass flowering, enabling the best dry matter and protein yields. Hungarian sainfoin is a promising perennial legume grass, able to stabilize and improve forage production in dry zones.
