Abstract: In the article, evaluation and selection of samples of alfalfa crop in rainfed lands, selection experimental 
areas according to economic valuable signs and characteristics are highlighted. The results of the research on the 
newly selected initial resources, which have high foliage and all other parameters compared to the model variety, 
are resistant to early blight, disease, and drought, are presented.

Introduction: Nowadays, due to the global climate 
change in the world, a sudden increase in air 
temperature during the most responsible stages of 
growth and development of agricultural crops, 
including fodder crops, and frequent occurrence of air 
and soil droughts in dry areas prevent the production 
of stable high and quality crops from these crops. 
Therefore, creation of new varieties of fodder crops 
resistant to adverse environmental conditions (high 
temperature, drought), diseases and pests for dry areas 
is one of the most urgent issues facing breeding 
scientists today. 

In achieving this goal, the role of alfalfa forage crops in 
pastures and irrigated areas is incomparable. 

By creating new high-yielding varieties of alfalfa with 
higher nutritional value, protein (protein) content, 
leafiness and seed yield, together with the increase of 
the nutritional value obtained from the existing areas, 

the needs for feed in animal husbandry will be met. By 
organizing the primary seeding of the new varieties 
created, they are supplied to farms and clusters 
specialized in livestock breeding. This leads to the 
expansion of high-yielding alfalfa areas, as a result of 
which high-quality feed is provided to livestock. 

In all rainfed regions, planting alfalfa allows more 
nitrogen nitrate to accumulate in the soil than planting 
wheat. Alfalfa enriches the soil with humus from the 
third year in the plain-hilly regions, which are semi-
provided with natural moisture [3,4]. 

The amount of protein in alfalfa stems is 17.8% in dry 
land and 17.7% in irrigated land. Fiber content is 26.6% 
in dry land and 24.9% in irrigated land. Alfalfa doubles 
the fertility of the land after itself [2,]. 

It is believed that there is almost no difference in 
protein and fiber content of alfalfa hay obtained in the 
first harvest of dryland and irrigated fields [1].

It should be noted that 100 kg of alfalfa hay contains 
48.8 nutrients, 100 kg of barley straw contains 35.8 
nutrients, and alfalfa crops can be harvested for 7-8 
years in a row in dryland farming, and 1-2 hay crops are 
provided every year [6]. 

Quick adaptation to environmental factors in different 
natural climate-soil conditions is important in genetic 
preparation of the variety [3]. 

METHOD 

At the Rainfed Agricultural Scientific Research Institute, 
new varieties and varieties of alfalfa selected together 
with local varieties were studied. All agrotechnical 
activities are based on the recommendations and 
methods developed by the Gallaaral Scientific 
Experimental Station in 1994, phenological 
observations, evaluations of various indicators in field 
and laboratory conditions State Commission for Testing 
Agricultural Crops (1985, 1989) and the former All-
Union Plant Science Institute (VIR, 1985) was carried 
out on the basis of methodological manuals developed 
in. 

RESULTS  

At the Rainfed Agricultural Research Institute, research 

and evaluation of alfalfa crops at the selection stages, 
selection of new lines with 10% higher hay and seed 
yields, 3-5% higher foliage and 1-2% higher protein 
content than the standard was carried out. 

As a result of scientific research, new lines with a higher 
level of foliage than standard varieties, high yield of hay 
and seeds were isolated. 

135 varieties of alfalfa samples were studied in 
Lalmikor lands this year. Growth, height, branching, 
foliage, green stem, hay and seed yield of alfalfa in dry 
areas are important. 

20 samples with high plant height were selected from 
the planted sample area. These samples differed by 4-
5 cm in height compared to other samples: k-6219 
(Mestny, Poland), k-6520 (Charta, FRG), k-6638 
(Washoe SSHA), k-6643 (Mestnaya, Tripoli), k -6652 
(BZ-422 Yugoslavia), k-7072 (USA, Caliverde, 35380) k-
7064 (Mongolia, 34705), the number of seedlings per 1 
m2 and plant height of these samples were also higher 
than other samples (Table 1). 

According to the results of the experiment, these 
selected samples were protected (isolation) from other 
samples and their seeds were taken separately.

As a result of long-term selection, 60 varieties and lines 
of alfalfa were studied in the 2nd year breeding nursery 
for biological characteristics and valuable economic 
traits. As a result of the experiments, the height of the 
samples is in the range of 89.4-94.5 cm, the branching 
of the plant is up to 6.1-7.3, the foliage is in the range 
of 45.6-57.7%, and the yield of blue stem per hectare is 
98-154.5 t/ha, dry hay productivity per hectare is 30.2-
53.3 tons/ha, seed productivity It was 0.6-2.2 ts/up. 
According to the two-year results, the height of the 
model "Aridnaya" variety was 89.4 cm, the branching 
of the plant was 6.1, and the yield of green stems was 

118.5 centners per hectare, the yield of dry hay was 
36.2 centners per hectare, and the seed yield was 1.2 
centners. 

It can be seen from the data obtained from the  

experimental sites No. 2006/1, No. 2007/5, No. 2007/9,

in terms of all signs and characteristics compared to the 
"Aridnaya" variety. The description of the lines that are 
superior to the model variety in terms of valuable 
economic characters and characteristics is presented in 
Table 3.
