The efficiency of pea seed stimulation with complex preparations

The article presents the results of laboratory studies on the stimulation of pea seeds with sulfuric acid salts of iron and magnesium, as well as in combination with a humate-containing complex preparation. The synergistic effect of the combination of drugs on the growth activity of pea seedlings was obtained. New knowledge has been obtained on the processing of pea seeds with growth-stimulating preparations for use in crop production in the Russian Federation.

Abstract Introduction. Unlike the seeds of grain crops, a much larger amount of productive moisture is required to obtain friendly pea shoots, approximately 150% of the seed weight. The steppe zone of Orenburg region in 80% of cases is characterized by insufficient moistening of the upper sown soil layer. In such conditions, agricultural practices that accelerate the processes of swelling and germination of seeds are very relevant.

Object. The object of the study is: seeds of Vortan peas and preparations for seed treatment: Borogum – M molybdenum, crystallohydrates of magnesium and iron sulfates.

Materials and methods. The treatment of pea seeds with preparations was carried out in plastic bags at the rate of consumption of 10 liters of working solution per 1 ton of seeds. The exposure of the treated seeds was 24 hours. Germination was carried out in a thermostat in the sand at a constant temperature of 20°C for 6 days. The laboratory experiment was based on a 4-fold repetition of 50 seeds in each repetition with subsequent processing of the experimental results. The smallest significant difference was calculated in the author's variance analysis program by B. A. Dospekhov.

Results and conclusions. Treatment of pea seeds with Borogum – M molybdenum biological preparation in combination with trace elements: iron and magnesium increases seed germination by 3% and 4% respectively. Separate use of single-component drugs does not give a positive result. Of the single-component preparations, only a 1% solution of magnesium sulfate (Epsomite) showed a significant result on the formation of sprouts in peas (an increase of 12.8%).Complex preparations in various combinations showed the best results on growth activity, the processes of formation of sprouts and roots in peas. The formation of the aboveground part of the seedling is more influenced by the combination of Borogum with magnesium (Mg): an increase of 28.3% relative to the control, and the roots – Borogum + Mg + Fe – 13.6% of the control. There is an obvious synergistic effect of enhancing the growth and development of peas at the seed germination stage from the addition of iron and magnesium sulfates to Borogum-M preparation, in which these trace elements were absent.
