METHOD OF CULTIVATION OF PERENNIAL FORAGE GRASSES IN THE NORTH Russian patent published in 2015 - IPC A01G1/00 A01B79/02 A23K1/00 

FIELD: agriculture.

SUBSTANCE: the method comprises tillage, spring sowing of perennial forage crops and their harvesting. For sowing the single-species seeding legumes are used or mixture of legumes and cereals with different terms of mowing ripeness. The selection of crops and sowing seeds is carried out, of at least three groups of perennial grasses: early-maturing grasses with harvesting term in the second decade of June, mid-maturing grasses with harvesting term in the third decade of June and late-maturing perennial grasses with harvesting term in the first decade of July. At that for planting early-maturing grasses the cultures are selected from the group: fodder galega with a seeding rate of 20 kg/ha; fodder galega and smooth brome, taken at a ratio of 1:0.75, respectively, with a seeding rate of 16 kg/ha and 12 kg/ha; fodder galega and meadow fescue, taken at a ratio of 1:0.75, respectively, with a seeding rate of 16 kg/ha and 12 kg/ha. For planting mid-maturing grasses the cultures are selected from the group: Lotus corniculatus with a seeding rate of 10 kg/ha; Lotus corniculatus and timothy grass, taken at a ratio of 1:0.5, respectively, with a seeding rate of 8 kg/ha and 4 kg/ha; Lotus corniculatus, red clover Magician and timothy grass taken at a ratio of 1:1.15:0.35; respectively, with a seeding rate of 6 kg/ha, 7 kg/ha and 2 kg/ha; red clover Trio and timothy grass, taken at a ratio of 1:0.35, respectively, with a seeding rate of 11 kg/ha and 4 kg/ha. For planting late-maturing grasses the crops are selected from the group: Swedish clover and timothy grass, taken at a ratio of 1:0.4, respectively, with a seeding rate of 10 kg/ha and 4 kg/ha; Lotus corniculatus, red clover Orpheus and timothy grass taken at a ratio of 1:1:0.35, respectively, with a seeding rate of 6 kg/ha, 6 kg/ha and 2 kg/ha.

EFFECT: the method enables to increase the resource base and harvesting times of cultivated fodder grasses and to obtain feed with high nutritional value.
