The effectiveness of pre-sowing seeds inoculation of naked oats with
microbial preparation Polymyxobacteryn was studied in field experiments during
2010-2012 on different fertilization backgrounds. The equivalence of biological
preparations impact on the crop productivity to the action of technical phosphorus
applied at a dose of 20 kg/ha was shown. The positive influence of bacteryzation
was confirmed in lyzimeter experiments on reduction of nutrients leaching and
water soluble humus through the soil profile beyond the root zone of plants.
Key words: naked oats, bacteryzation, Polymyxobacteryn, phosphorus,
lyzimeter.
Nowadays the naked oats is gaining its importance for agricultural
production and processing industry along with hulled oats. The potential yield of
modern varieties of hulled oats is 7 t/ha, whilefor naked oats that’s – 5–6 t/ha.
Naked oats grain can be used for food and feed purposes as well as for infant food.
The high price of commodity grain of naked oats on the international market
(200–240 USD/t) and the importance of culture in the domestic market of Ukraine
imposes requirements for improving the cultivation technologies for this crop.
Taking into the account the limited technical resources the optimization of
fertilizer use through the application of factors, which increase plants’ assimilation
of active ingredients of fertilizers, including phosphorus as one of the most
expensive agrochemical is of the big importance. At this, the application of
microbial preparations might be highly perspective.
Thus, the aim of our research was to determine the possibility of using
microbial preparation Polymyxobacteryn in growing technology of naked oats as
an alternative to some part of phosphorus fertilizers.
Materials and methods. The study was conducted during 2010–2012 on
sod-podzolic medium cultivated sandy soils in field and lyzimeter experiments in
Institute of Agricultural Microbiology and Agroindustrial Production NAAS.
The main agrochemical soil characteristics are presented in table 1.
The data presented in table 1 indicates the medium soil acidity, low number
of assimilated bases, low humus content, but a high level of easily hydrolyzed
nitrogen and mobile phosphorus, the content of exchangeable potassium in the soil
is low.
Scheme of experiments are presented in the corresponding tables. Pre-crop –
corn for silage.

Fertilizers were applied in the form of ammonium nitrate, superphosphate
and potassium chloride in spring prior to the spring pre-seeding cultivation. Pre-
sowing seeds inoculation was performed on the same day in accordance to the
practical recommendations for the application of microbial preparations [3].
Area of field experiment – 72 m2 (6 x 12 m), accountable area – 40 m2 (4 x
10 m), 4-fold repetition.
Farming techniques for naked oats - common for the region. Variety – Skarb
Ukrainy. Seeding rate – 4.5 million / ha. Harvest - solid, per plot.
Weather conditions during the years of studies had significant differences.
Thus, in 2010 in April-May the rainfall was only 69% from the norm (long-term
index – 97 mm), in 2011 – 9.5%, in 2012 – 68%, which indicates that two of the
studied years had insufficient moisture, while 2011 – was unfavorable. Overall,
through the growing season the precipitation was lower when compared to the
average (Table 2).
Results and discussion. The air temperature during the research years in
average during the growing season had exceeded the long-term values by2.8–
4.3 °C while rainfall was lower by 15–21 % comparing to the long-term indicators.
That conditions had resulted in average 1.7 t/ha with a range from 1.48 to 2.02 t/ha
in control (without fertilizer and inoculation). Inoculation of oat seeds with
Polymyxobacteryn had contributed to the formation of grain yield of naked oats at
the level of 3.01 t/ha, that was 1.8 times higher comparing to control with slight
differences between the years: from 3.1 to 2.88 t/ha (10%), while in the variants
without inoculation the variation was 23% (Table 3). The effect of inoculation at
our opinion is largely related to the intensification of the root system development
(the root mass of bacterized plants was higher than in control by 17–22 %).
Therefore, seeds inoculation with Polymyxobacteryn at growing of naked
oats after cultivated crops (corn) in variants without fertilization ensures a yield of
3 t/ha. Even in years with insufficient moisture, the yield was higher comparing to
control by 76%.

Maximum productivity of naked oats plants without seeds inoculation – 3.92
t/ha was obtained on the full fertilizer dose background with fluctuations in yield
from 3.42 to 4.24 t/ha. Application of Polymyxobacteryn had resulted in 4.2 t/ha
with a range from 3.8 t/ha to 4.48 t/ha. The highest grain yield was obtained in a
favorable by the moisture values 2012.
By decreasing the fertilizer dose from N60P60K60 to N40P40K40 (Table 3) the
yield of oats had also decreased significantly to 0.61 t/ha. Further reduction of
fertilizer dose to N20P20K20 had led to an average for the three years yield at 2.63
t/ha (lower by 1.29 t/ha), which is compared to the background control variant is,
respectively, 84% and 67%.
Seeds inoculation with Polymyxobacterynom on N60P0K60 background had
led to 2,64 t/ha yield. The same level of productivity was obtained in variant with
N20P20K20.
At the increased content of mobile phosphorus on medium cultivated sod-
podzolic soil type the impact of inoculation of naked oats seeds with
Polymyxobacteryn was equivalent to the effect of N20P20K20 dose of fertilizer,
which application costs were 400–410 UAH/ha. The costs for biological
preparation was 10 times lower, which is of big importance under the limited
resources conditions.

The other important statement, which comes from the research results is that
inoculation of naked oats seeds with Polymyxobacteryn is not practical to apply on
the background of full fertilizer dose N40P40K40. On background without
inoculation the increase of fertilizer dose from N40P40K40 to N60P60K60 ensures
extra 0,6 t/ha yield, equivalent in economic terms to 1 200 UAH, while the cost of
N20P20K20 dose of fertilizer in the form of nitroammophoska is 550–600 UAH.
Thus, inoculation allows to save 650 – 600 USD per hectare with oats.
Along with the search for the optimal combination of Polymyxobacteryn and
full fertilizer the possibility of unbalanced phosphorous introducing at oats
cultivation as well as possibility of technical phosphorus replacement with the
metabolic by-products of preparation’s biological agent (Table 3, variants 5, 6, 7
compared to the variant 1).
It was established that reduction of the phosphorus dose from P60 to P40 as
part of a full fertilizer had led to a decrease in grain yield of naked oats in average
for three years by 15%, at decrease to P20 – 21 % while complete exclusion of
phosphorus leads to a 35% decrease in yield.
In variants with Polymyxobacteryn the yield upon the complete fertilizer
dose was 4.2 t/ha, which was higher than in control variants by 7%. In variant #5,
with technical phosphorus dose reduced to P20 the yield was 3.93, on the level of
control; P20v at the normal nitrogen and potassium dose (variant #6, background 1)
the yield was 3.41 t/ha, which corresponds to the yield level in variant #5,
background 1 with full P40 dose as a part of a complete fertilizer. At complete
exclusion of phosphorus (variant 7) at seeds inoculation – the oats yield was 3.01
t/ha, equivalent to the yield level in variant #6 (productivity level – 77–79%
compared to control).
The ability of Polymyxobacteryn to reduce losses of nutrients, humic
substances and moisture was examined in stationary lyzometric experiment.

The studies had confirmed the possibility of technical phosphorus replacing
(P20) with seeds inoculation with Polymyxobacteryn which ensured efficient use of
water by bacterized oats plants, calcium, magnesium, nitrogen and, respectively, a
significant decrease of these elements runoff to groundwater due to infiltration
(Table 4).
Thus, the pre-sowing seeds inoculation with Polymyxobacteryn in the
technology of naked oats cultivation is an important resource saving factor with
sufficiently high economic effect.
