The Cultivation of Winter Wheat in the Ganja-Gazakh Economic Region

To obtain a high yield of wheat, the described cultivation technology should be observed. Consideration should be given to the biological characteristics of winter wheat, varieties, soil preparation for sowing, sowing dates, sowing rates, irrigation, fertilization, disease and pest control, and, finally, timely harvest without losses in accordance with relevant conditions. Since winter wheat is demanding on mineral fertilizers, one of the most important factors was the determination of the norms of nitrogen, phosphorus and potash fertilizers. Taking into account the fact that the chemical composition of winter wheat grain is not constant, but varies depending on the type and variety, climatic conditions, soil fertility, cultivation technology, a technology has been developed for growing 4 different varieties of winter wheat. For the Ganja-Kazakh economic region to obtain high-quality grain, which makes it possible to obtain an average yield of 50-60 centners per 1 ha.

Collective norms and modern contraceptive use in men and women: A multilevel analysis of DHS Program data in Nigeria and Zambia

Background: Social norms have long been understood as essential for demographic preferences, intentions and behavior, despite a lack of consistent definitions and measures in the field. Recent work has more clearly defined these norms, both at the individual and community/collective levels. However, past research on the effect of social norms on contraceptive use has focused mainly on the influence of individual-level norms, largely among women only, contributing to mixed findings. Methods: This study addresses this gap through the use of multilevel models to identify associations between collective gender, fertility, and family planning norms and individual use of modern contraceptives for both men and women, using recent Demographic and Health Survey (DHS) data from Nigeria and Zambia. Multiple measures of variation, including community-level random effects and the intraclass correlation, are calculated, providing evidence of the general effect of community factors on behavior. Results: Our findings support the importance of social, demographic and economic context on how collective gender, fertility, and family planning norms relate to modern contraceptive use. Different social norms are associated with use in the two countries, and, even within the same country, men and women’s use are influenced by different norms. Among the examined norms, only collective fertility norms were associated with use for all the groups examined, consistently associated with lower use of modern contraception. Overall, clustering at the community level explained a larger proportion of variance in individual use in men compared to women, suggesting that men’s behavior was more consistently associated with the measured social norms than women’s. Conclusions: These findings suggest that careful attention should be paid to understanding and measuring social norms when considering programs or policy around the provision of modern contraception and that these should not assume that social norms influence men and women’s behaviors in the same way.

Study of economically important traits to give an insight into the character association and their contribution in yield of sesame (Sesamum indicum L.) genotypes

Sugar beet is a crop of huge national economic importance. The beetroot plant shows great sensitivity to the abiotic factors especially to fertility of the soil. The lack of nutrients in the soil where this plant is grown weakens its normal development and significantly reduces its yield. Therefore, the present research work was planned to assess the impact of planting schemes and mineral fertilizer norms on the quality production of sugar beet. Research works were carried out in 2021-2022 with Caucasian variety of sugar beet on irrigated gray-brown soils. The field experiments were laid out under different plnating schemes and fertilizer application rates. In case of 50x20 cm planting scheme without fertilizer (control); dry matter 21.4%, sugar 15.6%, protein 5.38%, fat 0.61%, cellulose 5.69%, ash 4, 46% and nitrate nitrogen 147.5 mg/kg in wet mass, respectively were recorded in background (P120K90) variant; 15.9%; 5.85%; 0.65%; 5.77%; 4.53% and 163.8 mg/kg.The quality indicators of sugar beet, as well as root and fruit crops, increased significantly compared to the control and background (P120K90) variants in the increased rates of nitrogen fertilizer along with the background. The highest quality indicators were observed in the background+N90 variant, respectively 24.9%; 17.9%; 6.21%; 0.76%; 6.05%; 4.71% and 183.0 mg/kg. In the 50x20 cm planting scheme, which has more food space, the quality indicators were higher in each of the studied options than in the 50x10 cm and 50x15 cm planting schemes, depending on the mineral fertilizer norms. 0.8-3.5% dry matter, 0.3-2.3% sugar, 0.47-0.83% protein, 0.04-0.15% fat, cellulose 0.08-0.36%, ash by 0.07-0.25% and nitrate nitrogen increased by 16.3-45.7 mg/kg in wet weight. The amount of nitrates in the root fruits of sugar beet was much less than the permissible limit (250 mg/kg in wet weight). It is concluded that the highest indicators were obtained in the background+N90 and 50x20 cm planting scheme.

Effect of Inorganic Fertilizers on the Clover Growth in Gray-Brown Soils

The presented article presents materials on the effect of mineral fertilizers on the height of clover on irrigated gray-brown soils of the Ganja-Gazakh region. Due to the biological nitrogen collected by clover in the soil, more than twice the annual rate of nitrogen is saved in one cycle, thereby supplying other agricultural fields with nitrogen. Therefore, given the role of cotton as a strategically important plant, and alfalfa as a strong feed for livestock and restoration of soil fertility, the study of the fertilizer system of both plants in the cotton-alfalfa crop rotation is one of the most urgent tasks. The application of mineral fertilizers to alfalfa plants on irrigated gray-brown (chestnut) soils had a significant impact on alfalfa growth. High altitude means high yield. During the years of research, the highest height was observed in the N60P90K60 variant on average over 3 years. Depending on the norms of mineral fertilizers, the height of alfalfa increased by 6.3-29.5 cm compared to the variant without fertilizers.

INFLUENCE OF MINERAL FERTILIZERS ON THE HARVEST OF SPRING WHEAT VARIETIES

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.

Validation of the Fertility Norms Scale and Association with Fertility Intention and Contraceptive Use in India.

Social norms related to fertility may be driving pregnancy desire, timing and contraceptive use, but measurement has lagged. We validated a 10-item injunctive Fertility Norms Scale (FNS) and examined its associations with family planning outcomes among 1021 women and 1020 men in India. FNS captured expectations around pronatalism, childbearing early in marriage and community pressure. We assessed reliability and construct validity through Cronbach's alpha and exploratory factor analysis (EFA) respectively, examining associations with childbearing intention and contraceptive use. FNS demonstrated good reliability (α = 0.65-0.71) and differing sub-constructs by gender. High fertility norm among women was associated with greater likelihood of pregnancy intention [RRR = 2.35 (95% CI: 1.25,4.39); ARRR = 1.53 (95% CI: 0.70,3.30)], lower likelihood of delaying pregnancy [RRR = 0.69 (95% CI: 0.50,0.96); ARRR = 0.72 (95% CI: 0.51,1.02)] and greater ambivalence on delaying pregnancy [RRR = 1.92 (95% CI: 1.18,3.14); ARRR = 1.99 (95% CI: 1.21,3.28)]. Women's higher FNS scores were also associated with higher sterilization [RRR = 2.17 (95% CI: 1.28,3.66); ARRR = 2.24 (95% CI: 1.32,3.83)], but the reverse was noted for men [RRR = 0.61 (95% CI: 0.36,1.04); ARRR = 0.54 (95% CI: 0.32,0.94)]. FNS indicated better predictive value among women compared to men for key reproductive outcomes. This measure may be useful for social norms-focused evaluations in family planning and warrants cross-contextual study.

Vertical migration of nutrients and water-soluble organic matter in the soil profile under pre-sowing seed treatment with plant growth promoting rhizobacteria

Studies conducted in a stationary lysimeter experiment in the conditions of the washing water regime have shown that the use of PGPR for pre-sowing seed inoculation of agricultural crops reduces vertical migration of biogenic nutrients and water-soluble organic matter down the soil profile. The effect of seed inoculation with PGPR on the reduction of nutrient losses was not specific to the type of rhizobacteria and was similar for crops grown on different mineral fertilizers backgrounds (spring barley and winter rye seeds were inoculated with the nitrogen-fixing bacteria—Azospirillum brasilense 410 and A. brasilense 18-2, respectively, while maize seeds were inoculated with the phosphate-mobilizing Paenibacillus polymyxa KB). Seed inoculation has decreased nitrogen leaching down the soil profile by 4–9 kg/ha, phosphorus compounds—by 0.5–3.0 kg/ha, potassium—by 0.6–3.0 kg/ha, calcium—by 6–42 kg/ha, magnesium—by 3.0–6.0 kg/ha, water-soluble organic matter—by 0.8–8.0 kg/ha, subject to crop and norms of mineral fertilizers. Maize seeds inoculated with phosphorous-mobilizing P. polymyxa KB under crop cultivation on the cattle manure background did not affect the intensity of nutrient migration. On the other hand, the combination of green manure (narrow-leaved lupine as an intermediate crop) with pre-sowing seed inoculation had significantly reduced nutrient losses beyond the root zone soil layer. It is concluded that the use of PGPR in crop production on mineral and green manure backgrounds contributes to the preservation of soil fertility by limiting biogenic nutrients and water-soluble organic matter leaching with the water drainage down the soil profile. Pre-sowing seed inoculation had no significant effect on the vertical migration of nutrients in the soil on the background of cattle manure, due to the highly competitive environment created with the introduction of microorganisms from organic fertilizer, preventing the establishment of close interactions between PGPR and plants.

Daily labor mobility and the timing of entry into motherhood

The influence of female employment on fertility has been widely studied. However, there is a gap in the knowledge of the effect of daily labor mobility on fertility. The paper presents the study of the direct and indirect effects of commuting on the timing of entry into motherhood by comparison the age‐specific first‐birth rates of female commuters and non‐commuters. The effects appear in simultaneous decision making on childbearing and com‐ muting, and effects of cross‐municipal flows of population and earnings, and fertility norms diffusion on childbearing. Estimation strategy addresses the problem of potential endogeneity of commuting decision. The study uses individual register data from Sweden for women born in 1974 and residing in the Stockholm area following them from 19 to 32 years old. Results demonstrate that commuting women postpone their first birth. Commuters’ first‐birth rates are more sensitive to the changes in relative earnings, fertility norms, and the proportion of commuters in the residing population. Swedish family and labor policies significantly improve reconciliation of family and working life in comparison with many European countries. However, the study demonstrates that the policies do not address commuting costs (in a general meaning) in childbearing decision. The results can be used to explain the link between fertility and daily labor mobility in high‐income countries with a high proportion of women involved in daily labor mobility.

Influence of mineral and organic fertilizers on the properties of serozem-meadow soils, nutritional dynamics and productivity of amaranth

From the agrochemical properties of soils, their nutritional regime is of great importance. Since, plant nutrition is associated with it. In serozem-meadow soils, the nitrogen regime is in the most vulnerable position. Since the content of ammonium and nitrate nitrogen in the soil is at a minimum. The introduction of nitrogen fertilizers improving the nitrogen regime of the soil has a positive effect on the growth, development and accumulation of amaranth grain yield. The most optimal fertilizer nitrogen rate was 250 kg / ha against the background of P150K200 (1-experiment), an increase in the nitrogen fertilizer rate to 300 kg / ha against this background did not significantly increase the yield of amaranth grain. The study of the norms of mineral fertilizers without applying manure and in combination with it showed that mineral fertilizers (NPK) and manure at a dose of 30 t / ha significantly improve the poor nutritional regime of serozem-meadow soils, creating a high level of nutrition for amaranth plants. At the same time, the highest level of the nutrient regime of the soil was observed with the combined application of mineral fertilizers with manure. The highest yield was obtained on the N200P140K100 +30 t / ha option.

PRODUCTIVITY OF MELILOT (MELILOTUS OFFICINALIS (L.)) IN THE CONDITIONS OF RICE CROP ROTATION UNDER THE KYZYLORDA REGION

In the unfavorable environmental conditions of the Kyzylorda region, associated primarily with water scarcity, salinization and soil degradation, measures are needed for the cultivation of agricultural land and reproduction of soil fertility, associated with phyto-reclamation, the complex use of organic and mineral fertilizers, cultivation and introduction of salt-resistant crops, in particular legumes of perennial grasses, which, undoubtedly, it will become the basis for optimal functioning of agroecosystems, stable development of crop production diversification in order to obtain high-quality agricultural products. Melilotus, being an excellent pasture legume plant for restoring vegetation cover of saline soils, will make it possible to obtain high yields of off-season pasture production in territories that are currently unproductive.The article presents the results of studies to determine the effect of organomineral fertilizers on the yield and productivity elements of the clover. It was found that of the various studied norms of organomineral fertilizers, applying phosphorus fertilizers at a dose of P60 is the most effective, providing a stable and reliable increase in crop productivity by 53.5%. And the introduction of organomineral fertilizer "manure 15 t / ha + P60", where the highest yield of hay was 87.7 c / ha, the authors consider it ineffective, since the yield difference between them (2.2 c / ha) is insignificant, which is lower than the value of LSD05 = 4.7 c / ha. Variants of phosphorus fertilizers and a combination of manure of 15 t/ha with P60 had a significant impact on the quality and nutritional value of the melilot feed, where the protein content in the 1st year of the melilot life increased to 280.2 and 302.4 kg/ha, and in the 2nd year of life to 591.9 and 608.4 kg/ha.

ВЫНОС ЭЛЕМЕНТОВ ПИТАНИЯ ОВОЩНЫМИ КУЛЬТУРАМИ ПРИ КАПЕЛЬНОМ ОРОШЕНИИ В САРАТОВСКОМ ПРАВОБЕРЕЖЬЕ

To successfully solve the problem of import substitution of vegetable products, it is necessary to significantly increase the yield of vegetable crops in Russia. A large role in increasing yields belongs to the correct fertilizer system, the development of which requires knowledge of the removal of nutrients and the influence of biotic and abiotic factors on it. Taking into account that for vegetable crops grown in the steppe zone of the Saratov Right Bank, data on the removal of nutrients were not determined, the purpose of the research was to experimentally determine the removal of the main vegetable crops – tomatoes, late cabbage and eggplant, and to study the effect on this indicator and yield of drip irrigation regimes and norms of mineral fertilizers on the chernozems of the southern region. Experimental methods were used in the work – field and laboratory experiments to study the yield and removal of nutrients by the studied vegetable crops under different modes of water and mineral nutrition with drip irrigation, and statistical methods – dispersion and correlation analysis. The article presents the results of research on the influence of irrigation regimes and fertilizer rates on the removal of nutrients and the productivity of varieties of valuable vegetable crops during drip irrigation on the chernozem of the southern Saratov Right Bank; The coefficients of the removal of batteries per 1 ton of the main and by-products of tomatoes, late white cabbage and eggplant at different agrophones were determined. The dependences of the removal of nutrition elements of tomato varieties on the irrigation norm and the total dose of fertilizers, the removal of NPK eggplant from the doses of mineral fertilizers are established. It is proved that all the studied crops formed the highest yield at the calculated dose for an increased yield level, while their reaction to the improvement of the water regime was different. The highest yield of late white cabbage of the Amager variety 611 85.59 t /ha of commercial heads and eggplant fruits of the Black Handsome variety 88.69 t / ha was obtained under irrigation regime of 90% NV, and tomatoes – at 80% NV

Matematički rezultati istraživanja parametara koji utiču na ujednačenu produktivnost rasipanja mineralnih đubriva sa kombinovanim plugom, primenom grafo-analitičke metode

The correct application of mineral fertilizer norms and the study of effective energy saving methods, the use of fertilizers in soil and climate conditions for the cultivation of agricultural plants are the urgent tasks of modern agriculture.The main problem in the world is the uneven sowing and disturbance of the ecological situation during the application of fertilizers.So, in many developed countries, the mechanization of this field has been given a lot of attention. Many fertilizer spreading machines and equipment have been produced in this direction. However, in this field, accurate spreading of fertilizers and equal distribution in the soil remains a problem. Uneven fertilization significantly affects the characteristics of the crop and causes environmental pollution.The inhomogeneity of the field in terms of nutrients resulting from fertilization is often the main cause of uneven cropping. It causes yield loss in cereal crops, which can reach 25-60% in some years. Our research has determined that, depending on the design features of the spreaders and the quality of the fertilizers applied, the uneven distribution of the applied fertilizers can vary between 40-60% of the norm, which ultimately leads to nutrient deficiencies. It was observed that the productivity of cereal crops decreased by 11-15 centner/ha with the increase of uneven distribution of fertilizers in the field to 70-80%.In order to partially eliminate the scientific and technical deficiencies in grain growing, a combined plough was developed in our laboratory. Factors affecting productivity were analyzed by the grapho-analytical method of the combined plough, graphs were obtained by theoretical methods. Fertilizer rate, optimal selection of the speed of the aggregate creates conditions for obtaining the maximum productivity of mineral fertilizers in the field.Grapho-analytical methods are convenient for selecting the closest targets.

Fertilizer Application Rates Effect on the Structural Elements of Glycine max in the Conditions of the Samukh District (Azerbaijan)

The effect of sowing period, growing scheme and fertilizer norms on structure elements and Glycine max yield of on irrigated grey-brown (chestnut) soils of Samukh district is presented in this article. It’s defined, that when conduction sowing of soy-been on April 10-15 the quantity of beans and grains from a plant, the mass of grain from a plant and thousand seed weight and yield of grain was much more in comparison with early and late sowing at 45×10 cm growing scheme and at 10 t/ha + N60P90K60 fertilizer application rates in comparison with the variant without fertilizer.

Which Structural Interventions for Adolescent Contraceptive Use Have Been Evaluated in Low- and Middle-Income Countries?

Reducing adolescent childbearing is a global priority, and enabling contraceptive use is one means of achieving this. Upstream factors, e.g., gender inequalities, fertility norms, poverty, empowerment and schooling, can be major factors affecting contraceptive use. We conducted a systematic map to understand which structural adolescent contraception interventions targeting these upstream factors have been evaluated in LMICs. We searched eight academic databases plus relevant websites and a 2016 evidence gap map and screened references based on set inclusion criteria. We screened 6993 references and included 40 unique intervention evaluations, reported in 138 papers. Seventeen evaluations were reported only in grey literature. Poverty reduction/economic empowerment interventions were the most common structural intervention, followed by interventions to increase schooling (e.g., through legislation or cash transfers) and those aiming to change social norms. Half of the evaluations were RCTs. There was variation in the timing of endline outcome data collection and the outcome measures used. A range of structural interventions have been evaluated for their effect on adolescent contraceptive use/pregnancy. These interventions, and their evaluations, are heterogenous in numerous ways. Improved understandings of how structural interventions work, as well as addressing evaluation challenges, are needed to facilitate progress in enabling adolescent contraceptive use in LMICs.

Seeding Sowing Rates and Fertilizers Effect on the Biological Development and Yield in the Ganja-Dashkasan Economic Region

The article discusses the application of manure and inorganic fertilizers for Gossypium on irrigated gray-brown (chestnut) soils in the Ganja-Dashkasan Economic Region. The optimal terms of sowing and application of inorganic fertilizers were determined. In the variant of sowing seeds on April 10-15, the Gossypium yield in the control (without fertilizers) variant for 2 years was 32.8 cwt/ha, in the second variant - 35.3 cwt/ha. The increase is 3.5 cwt/ha or 11.3%. In the third option, these figures are equal to 40 cwt/ha; 7.2%; The most optimal result was in the variant with the application of NPK, where the increase compared to the control was 14.4 cwt/ha or 46.8%. As the norms of inorganic fertilizers (NPK) increased, the studied indicators decreased relative to the NPK variant. On the experimental site, the yield significantly increased at the end of the growing season due to the complex action of inorganic fertilizers during sowing on April 10-15. The largest amount of raw cotton was in the variety NPK.

Influence of some agro-technical measures on the yield of wheat of local variety “Istiklol 25” native to Uzbekistan

The yield of winter wheat depends on the biological characteristics of the variety, soil climatic conditions, water, light, feeding regime and applied agro measures. In the cultivation of winter wheat, the external environmental factor or agrotechnology used has a strong impact on yield or grain quality. High and quality grain can be grown when cultivation technology is adapted to the biological characteristics of the varieties. The cultivation technology used is required to optimally meet the demand for its vital factors in the stages of winter wheat orinogenesis. We presented the results of scientific research conducted in Samarkand region on the establishment of primary sowing of intensive varieties of durum wheat “Istiqlol 25” and the development of agro-technical methods to improve the quality of Istiqlol 25. In the variant where 4.5 million germinated seeds were used, the positive result was shown when the fertilizer norms were NPK 180:135:90.

Organic contents of residues and nutrients in the short-row crop rotation systems in typical agricultural lands of Uzbekistan
