The influence of the predecessor and different doses of mineral fertilizers on the yield and the quality of the winter wheat cultivar ‘Krasnodar 99’ were investigated. Investigations were carried out in the North-Kuban Agricultural Experiment Station in two ten- course crop-rotations: grain plowing and grain - grass plowing (stationary experience). The soil is the black soil, low in humus, powerful, with humus content 3,95-4,00%, depending on the nutrition in the arable soil layer (0-30sm), mineral nitrogen is 5,9-8,3 mg / kg of soil, exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. The protein content was mainly determined by the fertilizer dose. Enhanced and high doses of fertilizers contributed to an increase in the protein content to 12%.A strong correlation between protein content, agronomic methods and precipitation was determined
The reaction of winter wheat of Krasnodar
Agricultural Research Institute selection that is
included in the State Register of selection
achievements in the Russian Federation, on the
predecessor, the sowing time and the level of mineral
nutrition in 2008 - 2010 was studied in
"Severokubanskaya agricultural experimental station"
P.P. Lukyanenko Krasnodar Agricultural Research
Institute, located in the northern area of the region.
The objects of research were cultivars ‘Bezostaya 1’,
taken as a standard, ‘Tanya’, ‘Grom’, ‘Sila’, ‘Ligue 1’,
‘Irishka’ and ‘Yumpa’, with a specific weight of
strong wheat (excluding the cultivar ‘Bezostaya 1’) -
57.1%, essential - 28.6%, weak - 14 3%. The
predecessors are winter wheat, sunflower, white
mustard. Seed dates: the 20th of September (optimal
for determining the originator of the cultivar) the 1st
and 10th of October. The background of mineral
nutrition is N0P0K0, N60P30K30 and N120-160P90K60. The
soil is an ordinary powerful heavy-loam chernozem
with humus content in the soil layer 0 - 30 cm 3.95 -
4.00%, of mineral nitrogen - 8.3 - 10.7 mg / kg of soil,
of mobile phosphates - 22.4 - 26 6 mg / kg of soil, of
exchangeable potassium - 330 - 360 mg / kg of soil.
Weather conditions during the research were
extremely contrasting, both by the precipitation and by
the temperature conditions. Based on these studies, it
was found that five or six cultivars of this crop that
differ in biological and economic features, the reaction
on the predecessor, soil fertility and sowing terms as
well as adapted to the specific soil and climatic
conditions should be used to obtain consistently high
yields of winter wheat. Well-chosen cultivars, predecessors and sowing terms predecessors allow
without additional cost on the unfertilized background
to increase the yield on 0.20 - 0.79 t / ha. Together
with the growth of yield, the technological quality of
grain is improved: protein content by 0.5 - 2.4%, fibrin
content - 1.7 - 7.6%. The principle of mosaic use of
cultivars with specific predominance of strong wheat
is 57.1%, essential - 28.6%, weak - 14.3%, it allows to
produce the grain when you apply the minimum dose
of 12.5% protein content, 20.9% of fibrin content.
When using N90P60K60 respectively 13.3 and 23.6% at
a dose N120-150P90K60 - 14.4 and 26.8% with an average
of 13.5 - 24.0%
This article presents the experimental material obtained
from long-term stationary experiment of GNU
"Severokubanskaya agricultural experimental station"
in P.P. Lukyanenko Krasnodar Agricultural Research
Institute. Stationary experience was founded in 1978. It
had two ten-course crop rotations and combined graingrass
tilled. The ordinary black soil, low-humic, heavy
loamy in mechanical composition. The capacity of humus
horizon is 113-116 cm with a total content of humus
on the date of the experience beginning is 3.88%.
Arable (0-30cm) layer was characterized by the following
parameters: total nitrogen content - 0.22-0.24, mineral
-10,0-10,5mg / kg of soil, total phosphorus-0,16-
0,19%, labile phosphorus - 12,2-12,9mg / kg soil total
potassium -1,7-2,0%, exchange potassium- 386mg / kg
soil. The degree of saturation of bases is 80-90%. The
amount of absorbed bases is 30-40 m ekvg/ 100 g of
soil. The reaction of the soil solution is weakly alkaline
(PH water 8.0-8.2). The predecessor is winter wheat.
General Agrotechnics is recommended for a given soil
and climate of region. Solid mineral fertilizer were applied
as mineral fertilizers in combination with organic
fertilizer in the form of half-decomposed cattle manure. According to agro-climatic zonation the northern zone
of the Krasnodar region, where the research was conducted,
is related to the zone of insufficient watering
with hydrothermal coefficient 0.7-0.9 with an annual
rainfall of 350.5 to 899.8 mm. During the autumn and
winter period, which determines the accumulation of
water in the soil, from 150.3 to 426.8 mm of rain falls
or 30,4-68,9% of the annual amount. During the vegetation
of sugar beet from germination to harvest -112,0-
588,9mm of rain falls, with an average daily temperature
of the air 16,5-20,000С, including the period of the
greatest growth of roots and accumulation of sugar
from 3.2 to 557.1 of rain falls with air temperature
19,5-28,800С. Hydrothermal index is 0,01-2,83. During
the years of the research 19% of years have been characterized
as unfavorable (hydrothermal index 0.67),
44% of years as moderate on moisture supply and temperature
conditions (hydrothermal index 0.99) and 37%
of years as favorable (hydrothermal index 1.05). The
generalization of the research results obtained by us in
the long-term stationary experiment, allowed us to estimate
the impact of different standards and systems of
fertilizer on the productivity of sugar beet and sugar
content in the roots. On average, during the years of
research, the root harvest under the influence of fertilizer
amounted to 36,7-45,6 t / ha per unit area with the
addition to the control variant, that isn’t manurable,
amounted from 6.6 to 15.5 t / ha. The highest yield of
root is 43,0-45,6 t / ha which was obtained with systems
of fertilizer with complete mineral nutrition
Sunflower is one of the most important oilseed
crops, which are of great economic importance in
Russia and in the world. It is very adaptive crop
in terms of climatic conditions range, for that
reason it is cultivated on a vast territory of the
Russian Federation in various weather conditions.
Sunflower oil has high nutritional and taste
qualities, it is used numerously in food and is
applied in various fields of food industry. The
biologically active linoleic acid, phosphatides and
fat-soluble vitamins A, D, E and K, which are of
great nutritional value to humans, are contained in
the oil. According to its calorific capacity,
sunflower oil is on the first place among
vegetable oils. Due to biological characteristics of
sunflower, the Krasnodar region is the most
favorable region of the Russian Federation for
obtaining high and stable yields of this crop.
However, here the drought is observed during the
summer period and it affects adversely the
productivity and quality of sunflower seeds. The
increasing of resistance to unfavorable weather conditions is possible only based on detailed
study of physiological features of productivity
formation and seeds quality that is highly
important task in view of the current geopolitical
situation in Russia. One way of solving this issue
is the appliance of the growth regulators,
possessing anti-stress activity that improve the
quality of sowing seeds and increase the
productivity and plant resistance to stressful
environmental factors. These drugs include
growth regulator called Furolan, which was
created in KubGTU and is certified for use in
Russia. It is not toxic and is used in nano-dozes,
there is no its residual quantities in the products
and environment. Furolan has a positive effect on
physiological and biochemical processes,
improves the productivity of plants, their
resistance to unfavorable growing conditions by
increasing the resistance to dehydration as well as
to the risk of fungal diseases

The article studies the effect of various agricultural practices on the yield of two sunflower hybrids (Fortimi and N4LM 408) in the experiment. The studies were carried out in the central zone of the Krasnodar Region on the experimental fields of the JSC "Agrocomplex", Vyselkovsky district in 2018-2019. The experience was laid down according to the triple experience scheme (factor A - the primary soil cultivation techniques; factor B - sunflower hybrids; factor C - herbicides). It was found that with the change of technology (the method of soil preparation and the use of herbicides), the weed infestation of crops changed and a minimum number of them was noted on the variants where postemergent herbicides were used (Euro-Laytning and Hermes). The maximum yield was obtained using chisel and disk plowing with the treatment of sunflower crops with the herbicides Euro-Light and Hermes. There was an increase in yield compared with plowing and these changes are mathematically valid
The article deals with the effectiveness of mineral and
organic fertilizers in long-term application (for more
than thirty years) according to the influence on the
fertility of ordinary black soil of the Western Ciscaucasia
and productivity of sugar beet. The investigations
were carried out in the long-term stationary experiment
laid on the experimental stationary section "Severokubanskaya
agricultural experimental station" of P.P.
Lukyanenko Krasnodar Agricultural Research Institute.
The experiment was laid simultaneously in time
and space in two ten-course crop rotations and combined
grain-grass tilled. In the structure of sown areas
sugar beet occupied 10% of crop rotation area and was
placed after the winter wheat. During three rotations it
was studied: 1- control without fertilizer with natural
forming level of mineral nutrition; 2- minimal dose
N21P26K16 3- medium dose N43P52K33 ; 4 - N43P52K33,
5- high dose N96P104K68; 6- organo-mineral system¹
N43P52K34 + 12 t/ha of manure; 7- organo-mineral system²
N20P24K34 + II-III rotations tillage of straw crop
+ 6 t/ha of manure; 8- medium dose P52K33; 9- medium
dose N43K33; 10- medium dose N43K52. The soil which
is used by organo-mineral system with increased and
high standards of mineral fertilizers had higher concentration
of mineral nitrogen. Long systematic application of fertilizer had more noticeable effect on soil
phosphorus regime. The provision of soil by exchange
potassium tended to decline from rotation to rotation.
If at the completion of the first rotation the content of
this battery was at the level 362,0-433,0 mg / kg of
soil, in 2010, these values were 356,0-405,0 mg / kg of
soil, remaining at the level of increased and high provision
characterized to ordinary black-soil. Fertilizers
for crop rotation provided almost equal yield increase:
in the first rotation - 4,9-16,0 t / ha in the second 5,3-
17,1, the third 6,1-15,5 t / ha. In the moderate favorable
for moisture and temperature conditions during
the first and third rotation (hydrothermal index 0,8-
0,76), the value of sugar beet yield was 30,1-46,1 and
35,7-52,1 t / ha, in comparison with tougher conditions
for the second rotation (hydrothermal index 0,41-
1,96) higher up to 2,6-6,5 9,2-16,0 t / ha.
Research carried out in long-term stationary experiment
showed that long-term use of fertilizers prevents
to the loss of soil organic substances, supporting the
humus content at the level of 3.95-3.99%, and organicsystems
contribute to its reproduction to 4,01-4,21%.
soil nitrogen state is stabilized. However, there is a
tendency of decrease of the exchange potassium in
mineral fertilizer systems. In the conditions of insufficient
moisture supply of the northern zone of Krasnodar
region the most applicable norm is N60P90R60, both
in mineral and organic-systems, ensuring the collection
of root crops within 43,0-45,2 t / ha, with an estimated
amount of sugar 6,92-7, 14 t / ha. The given systems of
fertilizer provide the yield of root crops 53,3-56,0 t /
ha with the synthesis of sugar 8,19-8,70 t / ha. Increasing
the rate of fertilizer in 2 times from medium to
N120P160R120 doesn’t increase the productivity, reduce
sugar content of root crop to 0.4-0.8%. It is undesirable
to use fertilizer that are unbalanced in nutrition
elements in which root crops yield declines from 5.4 to
19.0%, and current biological sugar from 6,1 to 25,9%
EFFICIENCY OF CULTIVATION OF DIFFERENT WINTER WHEAT CULTIVARS IN THE CONDITIONS OF THE WEST CAUCASUS
The influence of the crop rotation type, predecessor and different doses of mineral fertilizers on the yield of two winter wheat cultivars (Lira and Krasnodar 99) was investigated. The investigations were carried out in the North-Kuban Agricultural Experiment Station in two five-crops: grain tillage and grain - grass tillage rotation of prolonged stationary experience. The soil is the black soil, low in humus, powerful, with humus content, depending on the power of nutrition backgrounds in the arable (0-30sm) soil layer is 3,95-4,00%, of mineral nitrogen is 5,9-8,3 mg / kg of soil, of exchangeable potassium is 330-360 mg / kg of soil. It was found that the maximum value of the winter wheat crop structure elements is noticed in the fertilizer systems with complete mineral fertilizer, and the minimum value - with PK and NK. Winter wheat yield depends on the crop rotation of 8-15%; from its predecessor - 15-18% and 27-31% of the fertilizer. Grain quality was generally determined by the dose of fertilizer. High and higher doses of fertilizers contributed to the protein content from 11.7 to 12.3% and fibrin content - 23,5-24,0%. A strong correlation between yield and agronomic methods was determined
Elements of the cultivation technology of winter wheat variety called ‘Antonina’ with the application of different backgrounds of soil fertility, norms of fertilizers, system of plant protection from weeds, pests and diseases were studied. The studies are conducted in a polyfactorial stationary experiment: factor A - soil fertility; factor B - system of fertilizers; factor C - plant protection system; factor D - methods of basic soil cultivation. In the experiment four models of soil fertility levels were studied: А0 - the initial (natural background); А1 - average (200 kg / ha Р2О5 and 200 t / ha of litter manure); А2 - increased (doses are doubled); when А3 - high (tripled). Based on the studies it has been established that to obtain a stable yield of winter wheat, an increased dose of mineral fertilizers should be used, which also ensures high grain quality indicators. The maximum yield increase of 37% was achieved on varieties in comparison with extensive technology. A significant increase of the protein content in the grain from 12.8 to 15.3% and gluten from 22.0 to 27.8% was found in the intensive technology - triple doses of fertilizers (NPK) and the use of integrated protection against diseases, pests and weeds. The introduction of high doses of mineral fertilizers contributes to the accumulation in the soil and grain of nitrogen, and also reduces the content of copper and zinc
The experiment considered the influence of different methods of agricultural technologies on the yield of winter barley in the dependence of the investigated factors. The studies were carried out at the experimental station of Kuban State Agrarian University in the conditions of multifactorial long-term soil monitoring. The experiment was carried out in a typical 11-field grain-grass-tillage crop rotation with the following alternation of crops: alfalfa, alfalfa, winter wheat, winter barley, sugar beet, winter wheat, corn for grain, winter wheat, sunflower, winter wheat, spring barley with sowing of alfalfa. Stationary experience is represented by the following factors: the level of fertility (factor A); fertilizer system (factor B); plant protection system (factor C) and methods of basic soil cultivation (factor D). The relationship between the influence of the soil fertility level, fertilizer norms, plant protection products, the soil cultivation system and yield, and the crop structure of the perspective winter barley variety ‘Gordey’ were determined. The soil is leached super-heavy light-clay chernozem with an average thickness of the humus horizon - 150 cm. It is found that fertilizer, soil treatment, seeding method, protective means increase the yield of winter barley and positively influences the elements of the yield structure. The yield increase in comparison with the control changed from 10.4 to 26.8 c / ha. The statistical processing data show that the fertilizer system (35.8%) and soil cultivation (27%) had a certain influence on the number of productive stems; the fertilizer system (44.6%) influenced the spike size, the fertilizer system (28%) and the tillage (32.8%) had influence on the amount of grain in the spike and also influenced the mass of grain from the spike
