ТЕХНОЛОГИЯ ВОЗДЕЛЫВАНИЯ ОДНОЛЕТНЕГО ВИДА КЛЕВЕРА АЛЕКСАНДРИЙСКОГО (TRIFOLIUM ALEXANDRINUM)

Abstract

The article discusses the results of studies of a new technology developed by us for the cultivation of an annual crop of Alexandrian clover (Trifolium alexandrinum), which includes the method of pre-sowing seed treatment with different terms and methods of sowing. Recently, along with agrotechnical measures to stabilize crop production, there is a need to cultivate non-traditional crops useful for human nutrition and health, and annual legumes play an important role in this process. A short vegetation cycle and intensive rates of crop formation make it possible to cultivate them in repeated crops in places with a favorable bioclimatic potential. Annual fodder grasses have a variety of uses and purposes. In the zone of sufficient moisture, these are good fallow-occupying crops. Annual leguminous grasses play an important role in creating a solid forage base: in summer they are the main source of green fodder production, they are used for making hay, haylage, silage, concentrated fodder in the form of grass meal, cutting, full-ration briquettes and granules; annual legumes can also be used as a concentrated feed in the form of grains. Harvesting grasses in the early phases of vegetation and with multi-cutting using artificial drying makes it possible to obtain fodder that is not inferior in total calorie content to oats and barley, and significantly exceeds them in protein content. Annual grasses are distinguished by a great diversity in terms of agrobiological features: they are widely used as preliminary crops on lands of radical improvement and as links in a pasture conveyor. The studies carried out by us over four years (2017-2020) revealed that the presowing treatment of Alexandrian clover seeds with double and triple mixtures of PABA, krezatsin and chicory infusion (against the background of preliminary stratification) provides a low-cost, environmentally friendly way of presowing stimulation of Alexandrian clover seeds with simultaneous hardening, adaptation and selection of the best species for use in a particular region, it is advisable to sow clover for seeds with a row spacing of 50 cm and a seeding rate of 6 kg/ha, and the optimal sowing time is the beginning of March and the first ten days of September.
