The article reviews the results of the economic and biological evaluation of adapted and prospective leek species. The analysis allows identifying the best species according to the productivity of the crop and biochemical composition of pseudostem in the conditions of the Ukrainian south
In the article, the results of studying of laws of inheritance of quantitative signs of winter barley are presented
The article discusses the effect of additional spikelets
in the variety of Bezostaya 1 on the realization of
productivity of the examined plants. We traced the
frequency of occurrence of multirov spikes and studied
the effect of this phenomenon on the productivity and
the main quantitative characteristics of the studied
plants. The article demonstrates the structure
distinction of productivity for abnormal and normal
ears. Experience was one-way vegetation, planted in
triplicate, time of experiment - 2013 - 2015 years.
The study revealed that the most frequent was the
emergence of 1-4 additional spikelets per spike. Some
quantitative characters had a slight deviation, these
include the number of spiked ledges on the kernek,
spike length and plant height. To a large extent we
increased the characteristic values such as the number
of grains per ear, number of spikelets per spike,
number of grains onto the ledge, head weight and the
weight of grains spike. We significantly reduced
weight of 1000 grains. It was revealed that more
localized spikes were mostly in the middle, the most
productive part of the ear. As a result, changes have
affected not only the quantitative characteristics
related to the productivity of the ear, but also its
architectonic whole
The results of the study farm «Zavet Ilyicha» JSC,
Leningrad district of Krasnodar region, are presented
in article to study the role of rolling phosphorus in soil
samples, organic fertilizers and grain output of winter
wheat. We examined the relationship between the
content of phosphorus in the soil and fertilizers are
introduced and subsequently with the quality of the
harvest of grain. To receive high harvests of crops,
primarily need adequate amounts of phosphorus in
soils in an accessible form. The next important step is
the use of different fertilizers (mineral and organic)
under crops. Without the use of fertilizers cannot
return key for plants of nutrients, such as phosphorus,
nitrogen and sodium in the soil, since agricultural
products makes the nutrients. What dose of fertilizer
use and profitable forms of these fertilizers, solves
every household depending on culture, soil, climate
and economy. We received during the research the
following results: for 4 year average contents of
phosphorus in soils of agro-landscape in General, au
pairs amounted to 27.2–31.4 mg/kg. Average levels of
phosphorus in the soils crop rotation fields amounted
to 26.9 and 30.9 mg/kg. Maximum values amounted to
115.0 mg/kg, while the minimum is about 3.0 mg/kg.
Also conducted analyses on the contents of rolling
phosphorus in manure polupereprevshem pigs and
cattle. Marked by a very significant gap in content of
phosphorus, which is associated with significant
differences in their feeding. In grain of winter wheat
for 4 years, phosphorus content accounted for at an
average of 3.41 g/kg; minimum and maximum
performance from 2.35 to 4.47 g/kg, in 2012.
Compared with 2012 phosphorus concentrations in
grain of winter wheat has gradually increased to 2015,
and accounted for 3.47 g/kg with minimum and
maximum thresholds ranging from 2.05 to 4.89 g/kg
The provisions to improve the efficiency of vineyards
are the selection of varieties different by ripening,
adapted to local conditions, as well as the use of a new
generation of fertilizers. According to phenological
observations and actual production period, the varieties
of table grapes are divided into groups by ripeness –
early and middle. According to the yield, there were
emphasized the following varieties: in the early group
– Cardinal (11,3 t/ha), Vostorg (Delight) (11,2 t/ha),
Bogatyrskiy (10,9 t/ha); in the middle ripening group -
Kishmish luchistyj (11,2 t/ha), Moldova (11,2 t/ha),
with large clusters (266-453 g) and berries (3,2-7,0 g),
a berries’ crush resistance was from average 850 g to
high up to 1528 g, berries’ strength of attachment to
fruitstems was high – 259 and solid – 666 g. It was
observed the positive benefit of foliar application of a
new generation of micro fertilizers. In the phase of
ripening of berries the total length of shoots of
fertilized variants was above the control variant for the
variety Ranniy Magaracha on 2,6-13,4%, for the
Karaburnu on 2,5-13,9%. Maturing shoots in this
phase was on the variety Ranniy Magaracha – 76,5-
92,4% (control variant – 74,6%), while on the
Karaburnu variety – 72,8-83,1% (control variant –
70,9%). Fertilizers contributed to the increase of leaf
area on the Ranniy Magaracha variety on 3,9-15,9
thousand sq.m/ha (control variant – 20,0 thousand
sq.m/ha), on the variety Karaburnu on 3,4-13,1
thousand sq.m/ha (control variant – 22,8 thousand
sq.m/ha). The yielding capacity on the fertilized
variants have increased by 7,1-23,0% depending on the
variety. The maximum yielding capacity was obtained
when using compound nanotechnological fertilizer
Nagro on the variety Ranniy Magaracha – 13,4 t/ha
and on the variety Karaburnu – 15,5 t/ha
