In our country, in recent years, spring oats was the most cultivated small grain cereal. The crops surface were around 200 thousand hectares in 2012 (194.500 ha). The aim of our field experiences was to improve the quality and production of spring oats crop. Therefore, this study assesses this crop technology in terms of number of sowing seeds correlated with a rational fertilization. In order to achieve the proposed objectives, a three factorial experience was set up with two different seed density per square meter, two fertilizers doses and 25 varieties of spring oats in 3 replications. Numbers of sowing seeds were: 250 germinated seeds/m2 and 500 germinated seeds/m2. Tested varieties were originated from Romania, Germany, Czech Republic and USA. Different doses of fertilizers were used: N50P50K0, N100P50K0. Results were tested with Fisher test and Duncan test with Polifact program. The varieties Mureşana from Romania and Gramena from Germany with an average production of 6 tones/hectare were the most productive studied crops. In conclusion, the experiment showed that there are differences between spring oat genetic varieties in terms of production.
