RARE HOST PLANTS FOR THE PRODUCTION OF FODDER IN THE NORTH URALS
In work the comparative estimation of productivity, efficiency and biochemical structure of nonconventional forage crops which is presented are recommended for introduction in a fodder field in the conditions of Northern Zauralye. The big set of the forage crops traditional and poorly extended in Northern Zauralye (25 kinds) was subject to research. From all studied forage crops, we allocate five most perspective high-yielding fodder plants: swerbiga east, hatima turingenskaia, a lupine long-term, a sorrel fodder, topinsolnechnik. At an estimation of duration of the vegetative period on which in the Tyumen region with short summer possibility of reception of big crops of various kinds of a forage and seeds depends, it has been revealed that on the average the growth period — flowerings it is weak widespread fodder plants has made 40-62 days. Productivity of green weight poorly widespread forage crops was within 76,0 81,0 t/hectares, thus a solid exit made — 20,9-27,9 t/hectares, fodder units — 14,9-17,4 t/hectares. On the basis of the received results expansion of assortment at the expense of introduction in field manufacture of forages nonconventional, poorly is recommended widespread forage crops which allow to increase the feeding period the forages balanced on nutritiousness.
