Prolonged cultivation of one culture at one and the same place worsens the conditions of nutrition and development of plants. The aim of the study was to carry out a comparative assessment of the crop rotation productivity of the Left Bank forest-steppe of Ukraine with winter wheat, winter rye and triticale, depending on fertilizer and predecessor, in order to identify the features of the short-rotation crop rotations. The research was carried out in a stationary experiment on typical black soils of the Panfily research station NSC "Institute of Agriculture of the NAAN". A comparative estimation of the productivity of non-rotational crop rotation in the studies was calculated on the basis of the volume of products from 1 hectare of crop rotation, which was counted on grain units according to the coefficients V.D. Grevtsova, feed units and digestible protein according to tables by M.F. Tomme. Based on the performed researches it was found that on typical black earths in the zone of unstable moisture of the Left Bank Forest-steppe the most productive was the link of short-rotational crop rotation with wheat winter wheat of winter-maize and a link of long-term crop rotation Soybean-wheat of winter-barley for the organo-mineral fertilizer system N60P60K60 + by-products predecessor.
Key words: crop rotations, crop rotation forms, field crops, humus, rotation, precursor, crop alternation, clear field, productivity, feed units, digestible protein
