SHORT-TERM FIELD CROP ROTATIONS WITH LUPIN AND SOYBEAN AS SOURCE FOR PRODUCTION OF BALANCED FEED E. I. Isaeva, O. S. Pedositch In 2010–2013 in the Russian Lupin Research Institute tests were done on gray forest soil in the South-West of the Non-Chernozem zone in Bryansk region within frame of perma- nent experiment to evaluate a hectare of rotational area in short crop rotations with lupin and soybean for feed and economical productivity of feed production. Test design consists of two crop rotations (spring rape–lupin–barley and spring rape–soybean–barley). Every crop rotation has been tested on the background of three technological plans (alternative, moderate, intensive). They differed in chemical level. Lupin crop rotations were more productive in real possibilities to get total amount of grain and actual digestible protein yield per a hectare of ploughed field as well as its provision with 1 energy feed unit. In the case of the alternative technology the differences in digestible protein yield made 110.9 kg (two-course crop rotation) and 125.1 kg (three-course crop rotation) in favour of narrow- leafed lupin crop rotation; in provision of energy feed unit with digestible protein it made 39.8 g and 15.1 g. In these crop rotations it’s possible to have feed of own production and provide high productive livestock with energy, protein and other nutritional elements at the lowest costs. Keywords: crop rotations, cultivations technologies, metabolic energy (ME), digestible protein (DP), energy feed unit (EFU).
