The article obtained hybrid seeds of rice using local and foreign varieties and samples for resistance to diseases and pests, shedding and lodging in field conditions, depending on biological and valuable economic characteristics, and determined the salt tolerance of the ridges on the basis of marker proteins. However, in the primary source nursery, the ridges were studied on valuable economic indicators and 10 ridges as early maturing ridges and 9 ridges as middle and late ridges were selected for use in future research as generations.

If in the control-green manure without crop experiment variants, the plant height was
80.6-79.1 cm, the yield horn was 14.2-14.1 pieces, the average joint spacing of the main
stem was 4.1-4.3 cm, the main stem thickness was 1.78-1.76 cm, when green manure crops
were applied, the agronomic soil properties and characteristics were positive for the plant,
coordinated the cotton growth and development, the plants were found to be relatively
vigorous and healthy growing and developing. This pattern was repeated in all
experimental years, and the data were observed in an analogous manner.
When green manure crops were applied in summer and autumn, the cotton
verticillium wilt incidence was reduced. This condition was observed throughout the
growth period. This, barley acted like rapeseed. For example, in the summer control-green
manure cropless variant, 4.9% of cotton plants were infected with verticillium wilt on July
15, 9.3% on August 1, and 13.3% on August 15, pea variant 4.5; 8.1; 12.4%, 3.8; 7.2;
11.8% in the chick-pea variant, respectively, raps variant 2.4; 5.1; 8.3%, barley variant was
2.7; 5.3; 8.9%.
In particular, in the fall, the control-green manure without crop variant was 5.8%
on July 15, 10.2% on August 1, and 14.8% on August 15, while the pea variant was 5.28.9;
13.1%, respectively; chick-pea variant was 4.8; 8.6; 12.1%, raps variant was 2.6; 5.3; 8.6%,
and 3.0; 5.8; 9.3% in the barley variant.
In the control-green manure cropless experiment variant, the yield was 35.1s/ha,
while in the green manure management variant 5.5-8.6 s/ha was obtained. In the
experiment, the highest yield (43.7 s/ha) and the most reliable additional yield (8.6 s/ha)
were obtained in the raps planted variant as a green manure crop, 42.8; 40.8 and 40.6 s/ha
yields were observed in barley, chick-pea and pea variants planted as green manure crops,

Global population increases drastically but the production of quality food grains has decreased in the same way that may results the poor nutrition content in the food. The reason behind less quality of food grain is the continuous use of chemical fertilizers in field in order to produce higher yield but these inorganic fertilizers increase yield and other side it decreases the soil fertility and cause effect to soil ecofriendly organisms and cause pollution in the soil and environment. Instead of using those inorganic fertilizers replace with using organic amendments like FYM, Poultry manure, Vermicomposting, sheep and goat manure, bone meal, slurry, sewage and sludge along with the bio fertilizers plays key role to enrich nutrient content, increase microbial population, improves water holding capacity in soil and provides the better aeration around plant rhizosphere. Growing of sole crop with organic amendments may reduce yield. Instead of these we fallow intercropping systems like cereals + pulse, cereal + oil crop, cereal + cereal crop may provide the better production and among intercropping systems cereal +pulse crop of wheat and chickpea with recommended ratios of (2:2,3:1,2:1,1:1) has shown the better results in crop production with good quality grain yield ,LER, better growth rate per unit area by better utilization of N2 from legume crop by fixation and makes profit to the farmer by reducing the incidence of disease, pest and weed .

The article elaborates on the possibility of increasing cotton yields by improving the agrophysical, agrochemical and microbiological properties of fallow soils by deep tillage at different depths between rows of cotton grown on irrigated fallow soils in the southern regions of the Republic of Uzbekistan. In variants 4 and 5 of the experiment, an increase in cotton yield was observed as a result of improved agrophysical, agrochemical and microbiological properties of the soil when cotton was cultivated at depths of 26-28 cm and 30-32 cm, respectively. In the experiments, when the cotton row spacing was loosened to a depth of 30-32 cm, the mass volume of the soil in the drive and subsoil layers decreased by 0,02-0,03 g/cm3, porosity by 2,0-2,1%, water permeability by 100-120 m3/ha increase in; humus content was higher by 0,004%, nitrogen content was higher by 0,007%, and phosphorus content was higher by 0,006%; As a result of the rapid development of the cotton root system, the efficiency of moisture and nutrient utilization has increased, and an additional 4-5 ts/ha of cotton has been proven to be obtained. The best results are obtained by cultivating cotton at a depth of 30-32 cm between rows. additional yield was obtained.

In the presented studies, 60 samples of the collection material of spring soft wheat from the VIR collection and from the Bioresource collection of agricultural plants of the Kemerovo Research Institute of Agriculture, branch of the SFSCA RAS) were assessed. The selection val-uable quantitative traits in the samples of spring-soft wheat were studied and the most adapted initial material of the conditions for the forest-steppe conditions of the forest-steppe registration of Siberia (Kuznetsk depression, Kemerovo region, Kemerovo district) in the conditions of 2015-2018 years was identified. According to plant height, 17 samples of spring soft wheat with lodging resistance of 9 points (on a nine-point scale) were identified, including five with low variability of the trait: Altai 70 (KP-076, RF Barnaul) – 2,86%, Siberian Alliance (k-65242, Bar-naul, Kemerovo) – 5,75%, AC Nonda (k-64562, Canada) – 7,70%, OmGAU 90 (k-65447, RF Omsk) – 8,33% , Valkeria (k-64552, RF Krasnoyarsk) – 8,86%. The height of plants largely de-termines the yield, r = 0,6011 and the elements of its productivity: the mass of 1000 grains r = 0,6580, the number of grains per ear, r = 0,6092, the mass of grain per ear, r = 0,5722 (R = 0,4821 Based on a set of features, the source material was selected for creating varieties of spring soft wheat with high adaptive properties (1000 grain weight, number of grains per ear, grain weight per ear): Biora (k-64358, Russian Federation Moscow), Ulgenya (KP-078), Karabalykskaya 89 (k-64702, Kazakhstan). Sources with high productivity were identified:

Research in the 80s of the XX century aimed at changing the hydromodular
zoning of irrigated lands of the Khorezm oasis in Uzbekistan, the distribution of irrigated
lands by hydromodular regions and the definition of scientifically based irrigation regimes
for cotton in each hydromodule region. This article presents the results of scientific
research on the implementation of hydromodular zoning of irrigated lands of Khorezm
region, the distribution of irrigated lands by hydromodular regions and the definition of
scientifically based irrigation regimes for cotton in the main hydromodular regions of
Khorezm region. Moreover, it provides information on the study of hydrogeological
conditions, the definition of irrigated lands in the new hydromodular areas of the oasis.
Irrigated lands of Khorezm region belong to one soil-climatic zone - desert zone, three soilameliorative
areas within this zone. For the first time electronic distribution of irrigated
lands of Shоvоt and Gurlan districts of Khorezm region on the basis of geographic
information system (GIS) technology, using the data of soil-lithological sections and
observational wells maps were created.
When irrigating cotton in the most common hydromodule regions VII, VIII and IX in the
region cotton, while maintaining the pre-irrigation the soil moisture at the level of 70-80-
60% LSMC (lowest soil moisture capacity), and cotton is grown at 3856 m3 / ha (VII), 2789
(VIII) and 2203 m3 / ha (IX) irrigated according to seasonal irrigation norms; 35.0, 38.9
and 39.8 С/ha of cotton, with a minimum of one quintal for growing cotton: 55.4; 71.7 and
110.2 m3 of river water is consumed.
