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.
