The article presents the results of studies evaluating the influence of growth stimulants and micronutrient fertilizers on the productivity and sowing qualities of Crambe Abyssinica. Growth regulators Albit - 40 ml/t, Gumat K/Na - 0.15 l/t and microelement fertilizers EcoFus - 0.5 l/t and Omex - 2 l/t were studied. Studies have shown that the most effective options are with seed treatment with the growth regulator Albit and the combined use of Albit + Omex. Here the greatest positive effect was obtained on the indicator of field germination of krambe (89.6%) and on the safety of plants for harvesting (96.8%), respectively. It was revealed that the variant with the use of Albit, Gumat K/Na + Omex and Albit + Omex most effectively increased the seed yield of Crambe, the seed productivity here was 2.92; 2.93 and 2.96 t / ha, respectively.  These options stimulated germination energy by 1.8-4.7% and laboratory germination by 3.8-9.1% relative to the control. The krambe oil content in the experimental variants was 36.14-39.76%, in the control - 36.04%. The highest oil content of seeds was noted on the variant with Albit - 39.76%. The use of Albit in combination with EcoFus and Omex contributes to the accumulation of oil in seeds up to 38.55 and 38.68%, respectively. The weight of 1000 seeds of Crambe varied in the range of 8.16-8.38 g in the variants with the use of drugs and 8.13 g in the variant without treatment. The germination energy and laboratory germination rate of Crambe Abyssinica varied between 52.7-79.8% and 69.5-86.5%, depending on the use of the preparations.

The aim of this research is to assess the varieties of winter camelina in terms of productivity and adaptability in a contrast agroclimatic environment of the Middle Volga region and the region of steppe Crimea in 2016–2018. The climate of the Middle Volga region is moderately continental. The precipitation varies from 350 to 750 mm a year. The average year temperature is 5.3 °C. The climate of the steppe Crimea region is continental. The average year temperature here is 15.1 °C and the precipitation varies between 350 and 450 mm a year. In average the yield of different camelina varieties fluctuated between 1.59 and 1.83 t/ha, depending on the environment condition index (Ii -0.19–0.46). In the Penza region, the Kozir and Baron varieties gave the biggest yield with the productivity of crops equal to 1.80 and 1.83 t/ha respectively. In Crimea, the biggest yield was given by the Dikiy variety (1.74 t/ha). The variability of productivity is low at 7.4–10.1% and medium at 11.5–13.2%. The Baron variety has a low variation factor (7.4 and 11.5%) regardless of a cultivation region. All varieties had high stability which was 1.20–1.25 and 1.30–1.46 depending on a region. The Baron and Kozir varieties had the highest stability reaching 1.46 and 1.25 respectively. All varieties had a high index of stability for this crop, equal to 0.50–0.59. Camelina is tolerant of all stress factors and forms a stable yield in different cultivation conditions. All varieties showed a great ecological adaptivity and flexibility with the bi values equal to 1 and varying between 0.92–1.07. The most stable and flexible variety in the case of the Penza region is Baron (bi=0.92; σdr2=0.07) while in the region of Crimea it is Kozir (bi=0.99; σdr2=0.07). The Dikiy variety has high adaptivity parameters in both regions (bi=0.93–0.97; σdr2=0.06). The variance analysis showed that the share of “variety” factor influence is from 38.4% (the Penza region) to 39.2% (Crimea). In the variety-region relationship the influence of a variety is 40.6%. The share of “years” factor influence is 21.7–24.6%, depending on a region.
