AGRO-ECONOMIC PRODUCTIVITY AND FODDER VALUE OF THE NARROW-LEAVED LUPINE VARIETY BELOZERNY 110 IN CASE OF GROWING ON DRAINED LOW-LAND PEAT SOIL IN KIROV REGION

Annotation
In the conditions of the existing protein feed shortage in the non-chernozem zone of the
Russian Federation, the cultivation of adapted leguminous crops on drained peat soils is a promising
direction. In 2023, a field experiment was conducted on the old-arable lowland peat soil of the drained
peat massif “Gadovsky” to cultivate the narrow-leaved lupine (Lupinus angustifolius L.) of the variety
Belozerny 110. Despite the abnormal weather conditions (cold and dry June, and excessive moisture
in July), the yield of green mass was 204.95 centners per hectare. This is 2.6 times higher than
the average Russian yield for annual grasses. The yield of crude protein reached 267 kilograms
per hectare. With a decrease in the content of crude protein (11.9 % in dry matter) and an increase
in fiber (34.5 %), the plants have a characteristic “carbohydrate” growth pattern. The energy
consumption per 1 ton of crude protein (8.8 GJ) is among the lowest, which confirms the high
competitiveness of this crop when grown on lowland peat soils.
