Abstract


Lucerne (Medicago sativa L.) is one of the most valuable forage plants, especially in the conditions of global
warming due to its drought tolerance and resistance to low temperatures. The plants have a very good regeneration after
mowing, and can provide annually high and nutrient-rich produce: protein, calcium, potassium, iron, carotene and
oestrogen, the latter being able to influence the reproductive cycle in animals. In this paper we aim to highlight the
productivity of six varieties of lucerne cultivated among 2015-2017 at the Sibiu Plant Varieties Testing Center located
north of Sibiu (coordinates: 45.835790, 24.148485). We used six alfalfa varieties in this area, three of which were created
at Fundulea National Institute for Research and Development for Agriculture (Magnat, Daniela and Teodora), two of
Pioneer (PR54V09 and PR55V48) and one of Trifolium A/S (Daisy) from Denmark. Each variety was cultivated in 5
repetitions, 4 for production, and 5 for other observations. There were 3-4 mowing per year, as follows: 1 at the beginning
of the bloom; 2 after 30 days and 3-4 to 40 days. The experimental parcels had 10 m
2
 harvestable each. Harvest from each
experimental plot was weighed. The dry matter was determined by oven drying at 80°C for 24 hours. The Anova test was
used for the statistical calculation and the difference.In the three experimental years, different production and quality
results were obtained depending on the variety and climatic conditions. Annual harvesting green yield was between 202.5
and 267.5 t in 2015; 263 and 309 t in 2016; 337 and 413.5 t in 2017. The dry matter content varied between 20 and
30.6%.It is found that the maximum yields were obtained in 2017, noting the varieties PR54V09 and PR55V48. The same
2 varieties were also noted for the dry matter content. In our case there was no positive correlation between the sum of
the precipitation and the production, so in 2016, when it rained 722.5 l was not the highest production, but in 2017 when
it rained only 589.6 l.
