- Abstract
In order to develop a technology for seed production of pasture alfalfa in the period 2014-2018, two agro-technical factors were studied: the time for harvesting the seeds (A) and the inter row spacing (M). The field experience is based on a candidate variety of alfalfa № 3АS, according to the block method in four repetitions at a plot size of 5 m² . To establish the optimal agro-technical term for harvesting the seeds, two variants were studied: A1 (first growth for seeds and the rest for forage) and A2 (second growth for seeds and first and third for forage). Factor M is also available in two versions: M1 – 12,5 cm and M2 - 50 cm inter row spacing. In the seed production of alfalfa (grazing type), a proven higher seed yield is obtained from the first growth compared to that from the second growth. It was found that the main indicators that contribute to higher seed yield from the first growth, compared to the second are the longer stems, the greater number of pods per inflorescence and the weight of seeds per stem. There were no significant differences in the mass of 1000 seeds depending on the studied two factors. There is a tendency of higher seed yield when growing alfalfa at a distance of 50 cm between rows.
