PRODUCTIVITY OF SPRING RAPE WHEN TREATING SEEDS AND PLANTS WITH HUMIC PREPARATIONS
2023
A. I., Erokhin
Laboratory tests showed that rape seeds treated with Sakhalin Sodium Humate exceeded the control seedlings length by 7.7-34.5% on the third day of germination and by 15.0- 23.6% on the seventh day of germination. Presowing treatment of rape seeds with Flor Humat Universal had different effects on growth, root and sprout development. Doses of seed treatment with the preparation: 200, 400 and 600 ml/t had little effect on the increase of seedlings length - 1.6-8.1% and their weight - 9.1-9.4% to the control variant. The density of rapeseed plants per 1.0 square meter exceeded the control (untreated seeds) by 10.9%. The best results were obtained from the application of Flor Humate universal on rapeseed seeds at a dose of 1 l/t, and then on the treatment of plants in the phase of the rosette of leaves at the rate of 0.7 l/ha. The green mass of plants was 42.8% higher than that of the control (untreated seeds), rapeseed yield exceeded the control by 0.22 t/ha, (10.4%), and the rapeseed oil content in the grown seeds by 1.99%. When determining the structural analysis of plants, it was found that treatment of seeds and plants of rape with Sakhalin Sodium Humate and Flor Humate Universal increased the number of pods (in average per plant) by 4.5%, the number of seeds by 2.3-7.5%, and the weight of seeds by 12.5 - 16.6%. Weight of 1000 seeds of rape exceeded the control seeds by 8.0 - 8.3%
