It was shown that pre-sowing seeds treatment of hulless oat with Microhumin
preparation can reduce the dose of nitrogen fertilizer on 20 kg/ha by reactant. The
highest yield increase – 0.65–0.77 t/ha was received in the variants with N20P60K60
and N40P60K60 background. Additional yield in variants with inoculation and under
N60P60K60 dose of fertilizer was 0.5 t/ha. It was established that yield increase was
obtained mainly due to the higher grain mass and index of productive tillering.
Keywords: sod-podzol light cultivated soils, hulless oat, Microhumin, mineral
fertilizers.
Currently the world area under oat exceeds 25 million hectares. In Ukraine oat
are grown as supporting fodder grains. Sown area of oats during the recent years has
ranged within 300 – 450 thousand hectares, while its main growing areas are
concentrated in Polyssia and the Carpathian Mountains. The largest producers of
grain oats for many years had remained Chernihiv region – about 130 thousand tons
per year, Zhytomyr region – 85–90 tons and Sumy region – 80–85 tons [1].
Along with hulled oats the hulless oat is becoming more important for
agricultural production and processing industry. The yield potential of modern
varieties of hulless oat is about 5–6 t/ha. Crops can be used for food and fodder
purposes without processing, which reduces labor and production costs.
The high price of commodity grain of hulless oats in foreign markets (200–
240 USD/t), and the big importance of this crop on the Ukrainian market, including
baby foods, requires optimization of cultivation technologies, including fertilization
system, maximizing the level of its biologization.
Thus, the aim of our study was to determine the possibility of using microbial
preparation Mikrohumin as an alternative to certain fertilizers dose in cultivation
technology of hulless oats.
Materials and methods. Experiments were carried out on sod-podzol loamy
light cultivated soils of Institute of Agricultural Microbiology and Agricultural
Manufacture NAAS. The soils were formed on the layered water-glacial deposits. By
the particle-size composition of parent-material horizons of sod-podzol soils of the
area are sandy loam and light sandy loam soils.
A characteristic feature of sod-podzol sandy loam soils is homogeneous of its
mineralogical composition with quartz domination. It results in significant
permeability of the soil profile, low buffering, poorness of parent-material horizons
with mineral nutrients, magnesium and calcium, low absorbing ability in relation to
exchange cations, unstable structure, tendency to crust formation, soil capping and
poor microbiological activity. That causes significant cost of farming practices,
including cost of fertilizers.
Basic physical, chemical and agrochemical parameters of soil used for
stationary experiments in the department of scientific support of agricultural
manufacture are shown in the table below (Table 1).

The experimental scheme was as following:
I. Without inoculation:
1. without fertilizer (control);
2. N0P60K60;
3. N20P60K60;
4. N40P60K60;
5. N60P60K60;
II. Inoculation with Mikrohumin:
6–10 – same fertilization options.
Fertilizers were applied in the form of ammonium nitrate, superphosphate and
potassium chloride. Phosphorus-potassium fertilizers were applied in autumn, while
nitrogen – at crop cultivation.
Mikrohumin, used in the experiment, is a complex biological preparation based
on the bacteria of Azospirillum genus and extract of vermicompost, which contains
physiologically active substances. Besides compounds of hormonal action,
vermicompost contains vitamins, macro elements and trace elements in chelate forms
due to their interaction with the available in vermicompost amino acids and organic
acids, including humic and fulvic acids. It should also be noted, that due to the
intensive development of microorganisms substrate accumulate polysaccharides of
bacterial origin during vermicomposting of organic matter. Preparation dosage –
200 grams per hectare seed rate.
Cultivation techniques for hulless oats were common for the area. Variety –
Skarb Ukrainy. Seeding period – second decade of April. Seeding rate –
4 500 000 seeds / ha. Record area – 48 sq.m, repetition – 4-fold. Harvesting –
continuous per plot. Experiments were carried during 2010–2012.
Results and discussion. The average data for three years of research indicate that
complete application of mineral fertilizers N60P60K60 had ensured 3.4 t/ha of oats yield
which was 2.4 times above the productivity in control variants – 1.44 t/ha. Reducing of
nitrogen dose to N40 had caused yield decrease on 0.38 t/ha or 11 %, while lowering of
nitrogen fertilization dose to N20 had resulted in – 0.87 t/ha or 26 % decrease.
Yield increase in variants with Mikrohumin inoculation had ranged from 0.50
to 0.77 t/ha and was the largest in variants with low doses of nitrogen N20–N40
(Table 2). Pre-sowing seeds inoculation with Mikrohumin had ensured 1.94 t/ha of
yield in control variant and 3.90 t/ha in variant with full dose of fertilizer N60P60K60
that was two times greater than in control. Exclusion of nitrogen had resulted in yield
decrease to 2.56 t / ha (34 %), application of N20 dose – to 3.18 t/ha (18 %), and N40
dose – to 3.79 t/ha (3 %).
The hulless oats yield within 3.02–3.18 t/ha was obtained both at application of
40 kg/ha of mineral nitrogen dose and Microhumin inoculation on N20P60K60
background, indicating the equivalence of the impact of the inoculant to no less than
20 kg/ha dose of mineral nitrogen. Observed features were also confirmed by grain
yield ranging within the 2.56–2.53 t/ha in variants with phosphorus-potassium
fertilizers (N0P60K60) and seeds treatment with Mikrohumin and N20P60K60 fertilizer
dose without inoculation. At the same time, the N40P60K60 dose of nitrogen combined
with inoculation was more effective than application of N60P60K60. At this yield
increase was 0.39 t/ha (Table 2).

According to the obtained results, the productivity increase in variants with
inoculation was caused by increment of tillering coefficients on 0.4 units by mean,
and mass of grain on 3–8 %, whereas the mineral nitrogen had changed these values
on 0.7–0.4 units and 6–14 %, respectively.
Observation of photosynthetic activity of plants in the two compared variants
(N60P60K60 without inoculation and N20P60K60 with inoculation) had showed no
substantial changes of maximum leaf area. Plants had formed 37–38 thousand
sq.m/ha of leaf area. At this, their photosynthetic potential was within 2.9–3.0 million
sq.m days/ha, which ensured oats yields at 3.4–3.9 t/ha level. The accumulation of
dry matter per unit area per day (net productivity of photosynthesis) in variants with
Mikrohumin inoculation had exceed the variant with complete application of mineral
fertilizers on 5.
It also should be noted, that photochemical reactivity during the panicle earing
was on the same level.

Summarizing the above, the pre-sowing inocualtion of hulless oats seed with
Mikrohumin allow reduction of mineral nitrogen fertilization dose in oats growing
technology on sod-podzol soils in the range of 20 kg/ha.
