Abstract and keywords
Abstract (English):
Issledovaniya provedeny v 2015 – 2017 gg. na temno-seroy lesnoy pochve v pyatipol'nyh sevooborotah na treh fonah pitaniya: kontrol' (bez udobreniy), mineral'nyy i organomineral'nyy. V zavisimosti ot klimaticheskih usloviy usrednennaya urozhaynost' zernovyh kul'tur v sevooborotah na estestvennom fone plodorodiya var'irovala v predelah ot 2,32 do 2,96 t/ga. Maksimal'nuyu urozhaynost' zernovyh kul'tur v sevooborotah vozmozhno dostignut' pri GTK na urovne 1,6 – 1,75 edinic. Naibol'shaya pribavka zerna ot udobreniy poluchena v 2017 g., v zernoparotravyanom i zernotravyanyh sevooborotah s nasyscheniem mnogoletnih trav, ona vozrosla na 1,43 – 1,86 t/ga po sravneniyu s kontrolem.

Keywords:
