В се- вообороте люпин обеспечивает не только свою высокую семенную про- дуктивность, но и увеличивает урожайность последующих культур, проявляя себя отличным предшественником зерновых. Литература 1.

LUPIN USE WAYS IN CROP ROTATION AS AN IMPORTANT FACTOR FOR BIOLOGIZATION OF FEED PRODUCTION SYSTEM UNDER CONDITIONS OF THE SOUTH-WEST OF THE NON-CHERNOZEM ZONE OF RUSSIA E. I. Isaeva In 1988–1994 and in 2006–2011 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 permanent experiment to evaluate the impact of different ways of lupin use in crop rotations on soil fertility and crop yield in different development terms of agricultur- al industry. Test design consists of two crop rotations with lupin green manure fallow (green manure fallow (lupin)–winter rye–lupin–fodder beet–barley and green manure fal- low (lupin)–winter triticale–lupin–spring wheat–spring rape–barley) and two crop rota- tions without fallow field (oat–lupin–fodder beet–barley–winter rye and spring rape– lupin–barley–winter rape–lupin–spring wheat). Lupin use as green manure stabilizes soil fertility in different crop rotations with different rotation terms. From 1988 to 1994 humus content increased in 0.2 %, from 2006 to 2011 it increased in 0.4 %, it occurred at alter- native crop cultivation technology without implementation of chemicals. It shows the di- rect effect of the crop rotation itself. Humus content decreased in 0.2 % during six years in the analogous crop rotation without lupin fallow with addition of straw and mineral fertilizers to a tilling field. Lupin use as a hay crop had positive effect on barley productiv- ity. Ploughing in of its total biomass surpassed the effect of the mineral fertilizer N60P60K60. Yield increasing of fertilizers made 5.7 metric center/ha but it was 9.3 metric center/ha of lupin. Lupin rotation secures higher and more stable crop yield. Different lu- pin inclusion to a crop rotation allows use biological factor in farming more extensively. Keywords: crop rotation, green manuring, hay crops, soil fertility, productivity .
