ABSTRACT
Studies show that the application of nitrogen fertilizers and glauconite sand positively affects the yield of winter
wheat. Applying 120 kg of nitrogen increases the grain content in the ear by 11.3%, and adding 1 ton/ha of glauconite
sand along with nitrogen increases the number of grains by another 3.9%. The grain mass per ear increases by 5.1-5.9%
when using 1-2 tons/ha of glauconite sand. As a result of fertilization, the weight of 1000 grains of the "Yanbash"
variety increases by 1.7-2.4%. Winter wheat yield increases by 62.3% when nitrogen fertilizers are applied, with an
additional yield increase of 13.4 centners/ha. Using 1-2 tons/ha of glauconite sand on the N120 background further
increases the yield by 5.8-5.0 centners/ha. Thus, the application of glauconite sand allows achieving high yields without
the use of phosphorus-potassium fertilizers, providing the plants with the necessary nutrients and improving the
chemical composition of straw and grain.

INTRODUCTION
The application of nitrogen fertilizers and glauconitic
sand has a positive effect on the structure of crop
elements (Table 1).
From the data provided, it can be seen that the
application of 120 kg of nitrogen led to an increase in
the grain content of the ear by 11.3%. The additional
application of 1 ton of glauconitic sand, along with
nitrogen, allowed for a further increase in the number
of grains per ear by 3.9% compared to the option
without fertilizers.
Our research shows that the use of 1 and 2 tons/ha of
glauconitic sand as local fertilizers, combined with

The provided data shows that the application of 120 kg
of nitrogen led to an 11.3% increase in the grain number
per ear. The additional application of 1 ton of
glauconite sand to nitrogen allowed for a further 3.9%
increase in the number of grains per ear compared to
the variant without fertilizers.
Our research shows that the use of 1 and 2 tons/ha of
glauconite sand as local fertilizers, combined with
N120, led to an increase in grain mass per ear by 5.1-
5.9%. The use of mineral fertilizers in the cultivation of
winter wheat creates conditions for the formation of
full-weight grains in the ear. The mass of 1,000 grains
of the "Yanbash" variety, as a result of the positive
effect of fertilizers, increases by 1.7-2.4% compared to
the first variant.
The experimental data indicate that the yield of winter
wheat is primarily determined by the application of
nitrogen fertilizers, which increases the yield by 13.4
c/ha or 62.3% compared to the first variant (Table 2).

The application of 1 and 2 tons/ha of glauconite sand
combined with N120 resulted in an increase of 5.8 and
5.0 c/ha or 16.6% and 14.3%, respectively.
Thus, the use of 1 ton/ha of glauconite sand for winter
wheat, in combination with N120, allows for yields of
over 40 c/ha without the need for expensive
phosphorus-potassium fertilizers.
The fertilizer system must fully meet the plant’s need
for nutrients and ensure their maximum uptake by
plant organs. A lack of even one essential nutrient in
the soil reduces plant growth and development due to
the imbalance of necessary elements.
We have determined the effect of various mineral
fertilizers on the nitrogen and phosphorus content in
straw and grain. The research showed that the
different nutrient availability created by applying
nitrogen fertilizers and glauconite sand had varied
effects on the chemical composition of straw and grain
(Table 3).

The provided materials show that the application of
nitrogen fertilizers increases the nitrogen content in
straw by 14.8% and in grain by 16.7%, while the
phosphorus content rises by 55% in straw and 17.6% in
grain compared to the first variant.
The use of glauconite-containing sands combined with
nitrogen improves the conditions for plant nutrition
with nitrogen and phosphorus. Here, the nitrogen
content in straw increases by 6.4% and in grain by 3.6%,
while phosphorus content rises by 6.5% in straw and
6.7% in grain compared to the N120 variant.
The primary indicator of grain quality is protein
content. Therefore, increasing protein in grain is a very
important goal, as it enhances the nutritional value of
the grain. The calculation results show a significant
increase in protein in the grain in the variant where
N120 + 1 ton/ha of glauconite sand was applied. In this
case, protein content increased by 2.33% compared to
the variant without fertilizers.
For every 1 c of grain and the corresponding straw
yield, the removal is 3.6 kg of nitrogen, 0.9 kg of
phosphorus, and 2.4 kg of potassium. It should be
noted that the highest nitrogen utilization coefficient
from fertilizers was observed in the variant where 1
ton/ha of glauconite sand was applied.
Thus, in the absence of phosphorus-potassium
fertilizers, the application of 1 ton/ha of glauconite
sandstone to winter wheat ensures a yield increase of
5.8 c/ha or 16.6%, and a protein content increase of
2.33% compared to fields where only nitrogen fertilizers
are used.
