Abstract:
The growth and development of cotton are
primarily influenced by soil fertility, agrochemical and
agrophysical properties, the availability of nutrients,
water, and air regimes, as well as plant density and the
sum of effective temperatures.
Keywords:
Mineral fertilizers, glauconite, glaucophos,
soil fertility, macroelement.
Introduction:
Soil
fertility,
agrochemical
and
agrophysical properties, nutrient availability, water and
air regimes, plant density, and the sum of effective
temperatures primarily influence the growth and
development of cotton.
In the first variant, mineral fertilizers were applied at a
rate of N250, P175, and K125 kg/ha. In the second and
third variants, glauconite and glaucophos were used
without mineral fertilizers at a rate of 900 kg/ha. In the
fourth and fifth variants, reduced (by 25%) rates of
mineral fertilizers were applied (N180, P130, K90
kg/ha). In the sixth to ninth variants, the NPK rates were
180, 130, and 90 kg/ha, while the glauconite and
glaucophos rates were 9020 and 1200 kg/ha,

In our field experiment, we studied the effects of
glauconite and glaucophos compared to the full rate of
mineral fertilizers (N250, P175, K125 kg/ha). We
examined these substances without mineral fertilizers
and with a reduced annual mineral fertilizer rate
(decreased by 25%) to N185, P130, K90 kg/ha.
The average cotton yield ranged from 21.9 to 34.9
c/ha. When applying mineral fertilizers at a rate of
N250, P175, K125 kg/ha (Variant 1), the yield was 32.0
c/ha. The application of pure glauconite without
mineral fertilizers at a rate of 900 kg/ha resulted in a
yield of 21.9 c/ha (Variant 2). This can be explained by
the insufficient macroelement content in glauconite
necessary for plant growth, despite its sufficient
microelement content. Applying glaucophos at a rate
of 900 kg/ha (Variant 3) resulted in a yield of 25.0 c/ha,
which is 3.1 c/ha higher than in Variant 2. The presence
of phosphorus in glaucophos contributes to increased
yield to some extent. However, the absence of
nitrogen and potassium in sufficient quantities
negatively affects cotton productivity. The application
of glauconite and glaucophos at 900 kg/ha without
mineral fertilizers did not achieve the same yield level
as Variant 1, where N250, P175, K125 kg/ha were
applied. When glauconite and glaucophos were used in
combination with mineral fertilizers, the annual NPK
rate was reduced by 25%, to N185, P130, K90 kg/ha.
The yield in these variants (Variants 4-9) ranged from
31.8 to 34.9 c/ha. Applying glauconite at a rate of 600
kg/ha along with mineral fertilizers resulted in a raw
cotton yield of 33.4 c/ha, which is 1.4 c/ha higher than
in Variant 1. The data in Table 1 indicate that further
increasing the glauconite rate to 900 and 1200 kg/ha
(Variants 6 and 8) did not lead to higher yields. The yield
remained nearly the same (Variant 8) or even decreased
(Variant 6) compared to Variant 4. When glaucophos
was applied at a rate of 600 kg/ha (Variant 5), the cotton
yield reached 34.9 c/ha, which is 2.9 c/ha higher than in
Variant 1 and 1.5 c/ha higher than in Variant 4.
It should be noted that increasing the glaucophos rate
to 900 and 1200 kg/ha (Variants 7 and 9) led to a yield
reduction of 2.4 c/ha. This indicates that for normal
growth, development, and increased cotton yield,
applying 600 kg/ha is sufficient. The yield increase of
raw cotton when using mineral fertilizers in
combination with glauconite and glaucophos, compared
to Variant 1 (N250, P175, K125 kg/ha), was 1.4 c/ha in
Variants 4 (600 kg/ha) and 8 (1200 kg/ha) with
glauconite. However, in Variant 6 (900 kg/ha), the yield
decreased by 0.2 c/ha. In Variants 5, 7, and 9, where
glaucophos was applied at rates of 600, 900, and 1200
kg/ha, the yield increases were 2.6 and 0.5 c/ha,
respectively (Table 2). However, in these variants,
mineral fertilizer use was reduced by 25%, while cotton
plants were still supplied with essential microelements.
The extraction of local mineral agro-ores is relatively
inexpensive. Therefore, from both economic and
environmental perspectives, these fertilizers are a
viable option for cotton nutrition.
