Abstract
The improvement of the fodder base of the full nutrition of farm animals is a priority direction of the development of agriculture in the region. Prevention of the process of degradation and reduction of productivity of meadow phytocenoses occurring under the influence of natural and anthropogenic factors determined the relevance of this work. The research was carried out on the basis of the Department of Agroecology, experimental nurseries and the chemical-analytical laboratory of the Magadan Research Institute of Agriculture (Magadan). The aim of the work was to obtain experimental data on the study of the effect of trace elements (Cu, Zn, B) on the productivity of meadow agroecosystems and the quality of forage phytocenoses. The effect of the combined use of macro- and microelements on the productivity of old-age crops of Eastern beckmania (Beckmannia syzigachne (Steudal) Fernald) and reed foxtail (Alopecurus arundinaceus Poire) and feed quality was studied. According to the results of the experiment, the introduction of copper against the background of a full mineral fertilizer had a positive effect on the yield of the eastern bekmania in the year of application, increasing the hay yield by 2.7 times and the protein yield per hectare by 3.8 times. Foliar fertilizing with boron and zinc in the year of application with a lack of moisture sharply increased the yield of crops of moisture-loving eastern bekmania by 7.9 times. The productivity and quality of the reed foxtail grass has been increased with the addition of copper (37.6%) and zinc (44.9%). The greatest increase in the protein content in foxtail hay was provided by the introduction of boron, in the year of fertilizing the herbage – 14.2%, in the aftereffect - 17.4%. Under the influence of copper, the content of carotene in the dry matter of the eastern bekmania hay significantly increased – in the year of application – by 124%, in the aftereffect – by 43%; and fat – by 15% and 8%, respectively, the calcium content increased significantly: by 25% compared to the control.
