In-Depth Information
Photosynthetic potential was the highest in ordinary crops, at the maximum norm
of seeding of seeds in a phase of full maturing, which averaged 0.79 million m
2
of
days/ha in three years of researches. In wide-row sowing (45 cm), the photosynthetic
potential of plants varies between 0.77-0.86 million m2 days/ha.
Forage mass was dependent on the methods of planting and seeding rates in the
foothills of the Republic of North Ossetia
