Relevance: it is known that there is a
significant shortage of sunlight in the northern
territories, which is a serious obstacle to the
cultivation of agricultural plants. Accordingly,
in order to replenish the stock of plant
products, residents of these territories are
forced to use imported products or make
stocks of their own.

The purpose of this study is to study the effect of
infrared radiation and urea on the growth of bean
sprouts (Phaseolus vulgaris)

Hypothesis: Infrared radiation and urea stimulate the
growth of bean sprouts (Phaseolus vulgaris)

§ Infrared radiation is
electromagnetic radiation
occupying the spectral
region between the red end
of visible light and
microwave radio emission.
§ Nitrogen fertilizers are
inorganic and organic
substances containing
nitrogen that are
introduced into the soil to
increase yields. (N2,
P2O5, K).

The method of obtaining urea in industry
2 NH3 + CO2↔H2NCOONH4 + 125,6 kj
H2NCOONH4 ↔ H2NCONH2 + H2O - 15,5 kj​

The practical part
Before starting the study, we wrapped several beans of white beans purchased at a
vegetable stall in a damp gauze cloth.

10.

The practical part
Before planting, we pre-prepared the
ground, sifted and cleaned of unnecessary
particles, urea was added to the pot of
fertilizers in the form of a solution (root
dressing) and sprouted white beans were
planted in three pots.
10

11.

The practical part
The control group of the experiment was represented by
beans grown in the traditional way, and the
experimental group was beans grown using infrared
radiation and urea.

12.

The practical part
The source of infrared rays was the Minin lamp, and the
source of nitrogen fertilizers was the specialized
concentrated fertilizer NPK.
12

13.

The practical part
The study took place for 28 days, the plants were
watered 2 times a day, urea was fertilized only before
planting, the plant was irradiated 1 time a day, despite
the fact that the plant grown due to infrared rays was
limited from sunlight.
13

14.

The practical part
The plant grew most rapidly in a pot with urea, 11 days
after planting, sprouts began to sprout in other pots, but
later their values began to approximately equalize.

15.

Suppose that for white beans it is
necessary to add 2 g of nitrogen per 1
sq. mm. For this, for example,
carbamide (urea) is used. The table
shows the nitrogen content of 46%.
This means that in 100 g of fertilizer
there will be 46 g of pure nitrogen.
We get: 2×100/46=4.347 g
The practical part
Result: 4,347g of urea (urea) should be
added per 1 sq. mm.
Conditionally, the formula can be
expressed as follows:
A×100/C=D
• A is a given amount of substance,
• 100 is a constant value,
• C is the content of the active
substance,
• D is the amount of fertilizer to be
applied to the soil.
An alternative greenhouse model

The practical part
​Cultivation technology (Phaseolus vulgaris) in alternative
greenhouses:
• Construction of an alternative greenhouse
• Delivery of fertile soils, in particular, chernozems
• Fertilization of the soil with urea obtained in laboratory
conditions and nitrogen fertilizer (carbamide)
• Pre-germination of beans (Phaseolus vulgaris)
• Preparation of automatic equipment and water supply
systems
• Planting of sprouted seedlings (Phaseolus vulgaris)
• The production of urea at plants in the northern regions is
cheaper than the monthly purchase of ready-made nitrogen
fertilizers. The area of a standard greenhouse is 3000 mm *
4000 mm, since it is on 1 quad. mm accounts for 4,347 g of
fertilizers, then 52,164 kg are needed, then 131 packages of
fertilizers will be needed per month, 1 kg - 250 rubles, 131
packages worth 32,750 rubles are spent per month, 393,000
rubles per year (Calculations per greenhouse)

Conclusions
•The assumptions made on the basis of theoretical material were justified, urea and IR radiation stimulate
the growth of white beans.
•According to our research, urea was the best way to stimulate the initial growth of beans
•The hypothesis has been proven - infrared radiation and urea stimulate the growth of bean
sprouts (Phaseolus vulgaris)
•Infrared radiation can to some extent replace sunlight in the northern regions of the world for growing
plants independently in alternative greenhouses.
•A technology for growing beans (Phaseolus vulgaris) in alternative greenhouses has been created and a
method for synthesizing carbamide in industry for further fertilizer production has been determined
•The most economically advantageous method of purchasing urea is production at factories in the northern
regions
