ABSTRACT 

The article presents the results of studies of various norms of mineral fertilizers, on varieties of spring wheat. Varieties 

adapted to the soil and climatic conditions of the cultivation zone tolerate adverse weather conditions well. The use 

of mineral fertilizers on such varieties at optimal rates is a promising direction for stabilizing and increasing yields 

without any special additional costs.

INTRODUCTION 

We know that in modern conditions, agricultural 

production places high demands on varieties of grain 

crops. The new variety should be highly profitable, 

stable yield and high grain quality. In order to increase 

productivity in a sharply continental climate, as well as 

to increase the gross grain harvest, it is necessary to

introduce new highly productive varieties of spring 

soft wheat into production. In solving the tasks of the 

agro-industrial complex to increase the yield and 

quality of grain of spring soft wheat, an important role 

is played by the adaptability of the variety to growing 

conditions, as well as the correct use of mineral 

fertilizers. 

It is known that the intensification of agricultural 

production is associated with a constant increase in the 

use of mineral fertilizers, primarily nitrogen. The 

introduction of large doses of nitrogen fertilizers under 

crops requires the study of migration and leaching, 

mobile nitrogen compounds in the soil. These issues 

are also relevant because the introduction of 

unreasonably high doses of nitrogen, readily soluble 

forms of nitrogen fertilizers in water, causes the 

danger of environmental pollution - water bodies, 

rivers, etc. 

When placing field crops in zones, natural conditions 

and biological characteristics of plants are taken into 

account. But the issue of zoning varieties of spring 

grain crops adapted to certain soil and climatic 

conditions has not yet found a proper solution. This is 

primarily due to the lack of spring wheat varieties for 

different regions and their seed production. The right 

choice of varieties and a number of other factors, such 

as tillage and fertilization, sowing, care of crops, timely 

harvesting, occupy one of the important places for 

obtaining high-quality crops. 

The aim of the research was to study the formation of 

yields of spring soft wheat varieties, when using 

various doses of mineral fertilizers in the extreme 

conditions of Karakalpakstan. 

MATERIAL AND METHOD 

Three varieties of spring wheat (Semurg, Saratovskaya-

29 and Zhanub gavhari) were sown with three norms 

of mineral fertilizers. The norms of mineral fertilizers 

were distributed according to the development phases 

from 30 to 75 kg / ha (active in-va) for top dressing. The 

size of the plots is 20 m2, in triplicate. 

The experiment was carried out on a plot of medium 

salinity (chloride-sulphate), medium loamy soils of the 

meadow type. In such areas, without prior washing, it 

is impossible to obtain full-fledged seedlings. Before 

sowing, the soil was washed 2 times. Groundwater 

occurs at a depth of 0.5 to 3.0 meters. The total 

nitrogen does not exceed 0.12 - 0.15%. Soils are less 

provided with humus and nitrogen. Records and 

observations were carried out according to the 

methodology of the State variety testing of agricultural 

crops (1989). Yield data were processed by the analysis 

of variance according to Dospekhov (1989). 

   Results. To obtain high yields, plants must be 

provided with the necessary living conditions in certain 

combinations and quantities at each stage of growth 

and development. 

  As can be seen from the data obtained, the cultivars 

started the booting phase with a difference of 5-6 days 

between cultivars. Thus, the plants of the Zhanub 

gavkhari variety, against the background of P70K50, 

where 30 kg were applied for plowing, and 60 kg of 

nitrogen during tillering, started the booting phase on 

April 27, the Saratovskaya variety on May 29, and the 

Semurg variety on May 4. These varieties, at a rate of 

mineral fertilizers of 210 kg/ha, started the booting 

phase on April 28, May 7 and May 4, respectively.   

Depending on external conditions, the duration of the 

ripening phases differs in different varieties in different 

ways.

As the data show, against the background of P70K50, 

where 30 kg were applied for plowing, and 60 kg of 

nitrogen were applied for tillering and ploughing, the 

plants of the Zhanub gavhari variety reached maturity 

on June 20, the Saratovskaya variety - 29 June 28, and 

the Semurg variety 24- June. Excessive standing 

density can also cause a decrease in grains per ear and 

a grain weight of one ear and a weight of 1000 grains. 

On the other hand, grain crops are able to some extent 

to compensate for the low density of standing, the 

increased number of grains and the mass of grain of 

one ear.   

Variety Saratovskaya - 29, with the introduction of 150 

kg of nitrogen against the background of P70K50, a 

crop of 27.5 was obtained; Zhanub gavhari 22.6; 

Semurg 25.3c/ha. With an increase in the doses of 

fertilizers up to 210 kg/ha, a crop was obtained from 

Saratovskaya-29 - 38.4; Zhanub gavhari - 32.5; Semurg - 

35.0 q/ha. 

DISCUSSION 

As a rule, in the field, depending on the weather and 

agricultural practices, there are significant differences 

in the yield of wheat over the years. Comparative 

assessment of the development of spike productivity 

elements in varieties of spring soft wheat will make it 

possible to identify varieties or groups of varieties that 

compare favorably with others in terms of the balance 

of development of productivity elements. The number 

of spikelets of an ear, as is known, depends on the 

length of the ear, as well as on the distance between 

them on the stem. According to the number of non-

grained spikelets, significant varietal differences were 

observed, which was a consequence of unfavorable 

conditions during the period of flowering and the 

formation of grains. 

Wheat requires a longer day to enter the generative 

phase. Plants in this phase react significantly to the lack 

of water, nutrients, especially nitrogen. In solving the 

problems of increasing the yield and grain quality of 

spring soft wheat, an important role is played by the 

adaptability of the variety to growing conditions [1].   

The largest reserve for increasing grain production, 

which ensures the sustainable development of the 

grain economy, is the use of mineral fertilizers. 

Calculations show that in the future, about 40% of the 

increase in the gross grain harvest will be provided due 

to this reserve [2]. 

  Fertilizers applied to the soil cannot be fully used by 

plants, since some of them are assimilated by 

microorganisms, washed out, or transferred into a 

form that is inaccessible or difficult to access for plants 

[3]. 

Nitrogen fertilizers promote the development of 

vegetative organs, increase tillering energy and 

protein content in grain. When compiling a fertilizer 

system, special attention is paid not only to the total 

amount of nutrients, but also to the distribution of 

fertilizers according to the timing and methods of 

application [4]. 

The average yield of a variety under stressful 

conditions characterizes the genetic flexibility of the 

variety [5]. The higher this indicator, the higher the 

degree of correspondence between the variety 

genotype and various environmental factors.  

 CONCLUSION 

Proper feeding of plants in the phases of development 

is of great importance. Also, the choice of placement 

and density of plants on the field, on which normal 

growth and development, as well as productivity, 

depends. And so, the targeted selection of varieties

that are well adapted to the soil and climatic conditions 

of the cultivation zone, as well as the use of mineral 

fertilizers in optimal norms, is a promising direction for 

stabilizing and increasing yields without any special 

additional costs. 

In conditions of insufficient and unstable moisture, 

local varieties, as more adapted to the conditions of 

the zone, form a high yield, and in drought conditions, 

they are distinguished by large, leveled grains with 

good performance. 

One of these areas is a variety adapted to the 

conditions of its cultivation.
