Abstract :

The field research was carried out in the Experimental Station of Variety Examination in Przecław in the seasons of 2012/2013-2014/2015. The first examined factor was nitrogen doses (50, 100 and 150 kg ha–1) and the second was winter varieties of camelina (Maczuga, Luna, Przybrodzka). The experiment was established on alluvial soils developed from silt loam. The soil was classified in valuation class IIIa of the good wheat complex. The highest dose of nitrogen (150 kg ha–1) caused a significant increase of plant height and of the degree of plant lodging, and additionally an increase in the seeds total protein content and a decrease in the level of crude fat in comparison to the treatment with the dose of 50 kg N ha–1 . The use of nitrogen in doses of 100 or 150 kg ha–1 resulted in a significant increase in the number of silicles per plant, number of seeds per silicle, SPAD index value, and seed and oil yield. The variety Luna was characterised by higher plant density before harvest compared to the variety Przybrodzka, as well as taller plants in relation to the variety Maczuga. Variety Luna were characterised by the highest values of LAI and degree of lodging. The variety Maczuga, compared to Luna, had significantly higher performance characteristics such as the number of branches per plant, number of silicles per plant, number of seeds per silicle, SPAD index, oil yield and total protein content in seeds.
