INFLUENCEOF GROWTH STIMULANTS AND MICROFERTILIZERS ON THE PRODUCTIVITY OF CRAMBE ABYSSINICA H.

Abstract

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.
