The organization of animal feeding in the summer and
procurement of fodder for the winter are of great importance.
The sowings of sugar sorghum can become a
reliable and stable source of fodder even in the regions
with insufficient humidity. It is a unique drought tolerant
crop, which can be used as green mass, hay, silage,
grain, mono fodder, briquettes. The article gives the
study results of green mass and absolutely dry substance,
and the assessment of cultivation efficiency of such sugar
sorghum varieties and hybrids grown in FSBSI ‘I.G.
Kalinenko ARRIGC’ as ‘Zernogradsky yantar’, ‘Debyut’,
‘Listvenit’, ‘Zersil F1’, ‘Elisey F1’. The productivity
of green mass and dry substance of the new variety
‘Listvenit’ and the hybrid ‘Elisey’ exceeded the standard
variety on 7,0-5,0 t/ha and 2,30-0,74 t/ha respectively.
The cultivation technologies of sweet sorghum varieties
and hybrids produced the high net energy of 69,6-121,9
GJ/ha with the coefficient of energy efficiency of 3,72-
5,08. As for the energy, the cultivation technology of the
sweet sorghum hybrid ‘Elisey’ can be considered as the
most efficient variant, as it produced the maximum net
energy of 121,9 GJ/ha with the coefficient of energy efficiency
of 5,08
The study was carried out during 2010-2015 years in the
All-Russian research Institute of Grain Crops named
after I.G. Kalinenko (the laboratory of the cultivation
technology of plowing crops), situated in the southern
soil-climatic zone of the Rostov region, which is characterized
with the unstable and insufficient humidity. The
trials were conducted on the heavy loamy, calcareous
chernozem obyknovenny (natural blacksoil). The object
of the study was the grain sorghum variety ‘Zernogradskoe
53’, approved to use in the Rostov region. The agroclimatic
conditions during the years significantly differed
during the vegetation in the amount of precipitations
(from 110.2 mm in 2010 to 200.2 mm in 2013) and
in the temperature regime (from 2512.9 0С in 2010 to
2788.8 ºÐ¡ in 2015), that allowed evaluating the grain
sorghum productivity more objectively. The article gives
the study results of the effect of the weather conditions
on the duration of vegetation, productivity and grain
quality (content of protein, oil, ash and fiber). The article
showed the estimated interconnection among the sum of
active temperatures, precipitations and hydrothermal
coefficient during the sorghum vegetation with the principal
economic-valuable traits of grain sorghum. The
sum of active temperatures showed the greatest effect on
the duration of the vegetation (r=0.89); the sum of precipitations
during the vegetation had the greatest effect
on the productivity (r=0.80). There was determined the
strongest positive correlation of the sum of active temperatures
with the content of protein in the grain sorghum
kernels (r=0.80) and the average negative correlation
with the content of oil (r=-0.69). The sums of active
temperatures and precipitations, when the grain sorghum
gives the largest productivity, were established
