An artificially developed intergeneric hybrid
Festulolium (+Festulolium
F. Aschers,
et Graebn.) is the best forage crop with high energy and protein nutrition value which can be used
for green fodder when creating cultural haylands and pastures. The advantages of this crop are
high regrow capacity, high content of sugars and good winter hardiness. Wide use of this new
crop in fodder production is constrained, firstly, because the crop is yet new and little known and,
secondly, because there is a lack of seeds due to imperfections in the production technology.
There are still very few scientific studies on the biology and technology of
Festulolium
cultivation
in the forest-steppe of the Central Chernozem Region of Russia. In our works we were the first
to study the biological features of
Festulolium
and develop the main technological methods of
growing and harvesting its seeds. The work was carried out in long-term studies of the
Department of Crop Science, Forage Production and Agricultural Technologies of Voronezh
State Agrarian University in 2009
2011. The soil in the experimental plot was leached medium
loamy chernozem. The experiments involved the VIK-90
Festulolium
variety with the preceding
crop being the vetch-oat mixture harvested for green fodder. The soil preparation was
conventional for seed herbage of perennial grasses in the Central Chernozem Region. The
associated records and observations were made according to conventional methods adopted in
the seed production of perennial grasses. A high efficiency of the Aurorex (0.55 L ha
-1
) and the
Dicamba (0.15 L ha
-1
) herbicides in the suppression of annual and perennial dicotyledonous weed
plants has been identified. The application of these herbicides has significantly reduced (by 40-73%) the weed infestation of seed herbage in the first year of vegetation and, as a result, has
improved its structure and crop quality. The use of the developed agricultural techniques allows
reducing the energy costs and receiving an average of 433
496 kg ha
-1
of certified seeds.
