The world cereal production and supply as well as their trade, stock and losses are important indicators of the world market of cereals. They play a huge role in ensuring food security. The aim of this research is to identify the relation of the indicators of the world grain crops market (production, supply, losses, trade, stocks) and the level of malnutrition Prevalence of Undernourishment (PoU) among the world's population. Based on data from the Food and Agriculture Organization of the United Nations (FAO), a correlation-regression analysis was conducted between indicators of the global grain crops market, in particular: the wheat market, the fodder market of grain crops, the rice market and PoU of the world population for the period 2013/14 – 2020/2021 marketing years. It has been proven that there is a close, statistically reliable relationship between the above mentioned indicators, except for grain stocks and POU. The analysis of the world cereal market showed that among the indicators characterizing its conditions, the indicator trade in grain crops (r = 0.851; D = 0.724; F = 3.968, (F > F t ); z = 1.26; rL = 0.37; rU = 0.97) has the highest level of correlation. It was found that with an increase in the volume of world cereal trade by 1 million tons, the PoU level will increase by 0.018%. A review of literary sources proves that the problem of ensuring food security, in particular with regard to reducing the level of starvation and malnutrition, cannot be solved only by fighting climate change, overcoming socio-economic and military problems, fighting pandemics, etc. Its solution to a large extent depends on fair, uniform export and import of food products, as evidenced by the calculations. A separate direction for solving the problem of the spread of malnutrition is the elimination of the policy of highly developed countries regarding the application of individual sanctions against countries with high PoU values, in particular, the Central African Republic, Madagascar, Haiti, Afghanistan, Chad, Congo, Lesotho, Liberia, Mozambique, etc.

Światowa produkcja i podaż zbóż, a także handel nimi, zapasy i straty są ważnymi wskaźnikami światowego rynku zbóż. Odgrywają ogromną rolę w zapewnieniu bezpieczeństwa żywnościowego. Celem badań jest identyfikacja zależności wskaźników światowego rynku zbóż (produkcja, podaż, straty, handel, zapasy) a poziomem niedożywienia (PoU) wśród ludności świata. Na podstawie danych Organizacji Narodów Zjednoczonych ds. Wyżywienia i Rolnictwa (FAO) przeprowadzono analizę korelacji-regresji pomiędzy wskaźnikami światowego rynku zbóż, w szczególności: rynkiem pszenicy, rynkiem paszowym zbóż, rynkiem rynek ryżu i PoU światowej populacji w latach gospodarczych 2013/14 – 2020/2021. Wykazano, że istnieje ścisła, statystycznie wiarygodna zależność pomiędzy wymienionymi wskaźnikami, z wyjątkiem zapasów zbóż i POU. Analiza światowego rynku zbóż wykazała, że wśród wskaźników charakteryzujących jego warunki znajduje się wskaźnik handlu zbożami (r = 0,851; D = 0,724; F = 3,968, (F > F t ); z = 1,26; rL = 0,37; rU = 0,97) wykazuje najwyższy poziomem korelacji. Stwierdzono, że wraz ze wzrostem wolumenu światowego handlu zbożami o 1 milion ton poziom PoU wzrośnie o 0,018%. Przegląd źródeł literackich dowodzi, że problemu zapewnienia bezpieczeństwa żywnościowego, w szczególności w zakresie ograniczenia poziomu głodu i niedożywienia, nie można rozwiązać jedynie poprzez walkę ze zmianami klimatycznymi, przezwyciężanie problemów społeczno-gospodarczych i militarnych, walkę z pandemiami itp. Jego rozwiązanie w dużej mierze zależy od sprawiedliwego, jednolitego eksportu i importu produktów spożywczych, co potwierdzają wyliczenia. Odrębnym kierunkiem rozwiązania problemu szerzenia się niedożywienia jest eliminowanie polityki krajów wysoko rozwiniętych w zakresie stosowania indywidualnych sankcji wobec krajów o wysokich wartościach PoU, w szczególności Republiki Środkowoafrykańskiej, Madagaskaru, Haiti, Afganistanu, Czadu, Kongo, Lesotho, Liberii i Mozambiku.

Yield and the course of crop vegetation are the result of the interaction between the level of cultivation technology and the course of meteorological conditions, which are a variable production factor. The aim of the study was to quantify the effect of meteorological conditions on the course of development stages and yield of winter wheat cultivated in two technological variants (A1 - medium-intensive and A2 - intensive). The paper uses data on yield and timing of winter wheat development stages from four Experimental Stations for Variety Testing (Pol. Centralny Ośrodek Badania Odmian Roślin Uprawnych - COBORU) experimental stations from 2007-2016 located within the Upper Vistula and Upper Oder River basins. To determine the dependence of the length of development stages of winter wheat on the values of selected meteorological elements, the linear regression metod, correlation coefficient. It was found that the lengths of the selected developmental stages are positively correlated with air temperature and negatively correlated with the sum and number of days with precipitation in these stages. A 1°C increase in air temperature resulted in a shortening of the shooting - heading and heading - full maturity periods by 2.5 and 2.8 days respectively. An increase of 100 mm of precipitation in the periods sowing - full maturity and heading - full maturity resulted in an increase of these periods by 5 and 10 days. Increasing the number of days with precipitation by 10 days in the sowing - full maturity and heading - vax maturity stages resulted in extending these stages by 4.1 to 4.4 and 7 to 7.5 days for the A1 and A2 cropping technologies, respectively.

Micronutrient deficiencies in agricultural soils significantly affect crop productivity and the nutritional quality of produce, posing potential risks to human health. Abandoned mine tailings, which are rich in micronutrients, can serve as an effective solution to enhance the nutritional value of crops while also mitigating environmental impact. In this study, the soils were sourced from the semi-arid Doukkala region in western Morocco, while the tailings were obtained from the abandoned Kettara mine in the nearby Marrakech region. This study assessed the biomass and bioconcentration of wheat (Triticum aestivum L.) grown in three different soils amended with treated mine tailings (TMT) at doses of 0, 0.2, 1, 2, and 4 g·kg-1. The experiment, conducted under greenhouse conditions and in pots, employed a split-plot design with three replicates, monitoring morphological parameters and plant biomass. Concentrations of Cu, Fe, Zn, and Mn in wheat grains were measured by inductively coupled plasma-atomic emission spectrometry (ICP AES) after harvest. The results indicate an increase in root length, shoot height, number of tillers, shoot biomass and grain biomass with TMT amendment doses of less than 1 g.kg-1 soil, by 13.6, 42.1, 42.6, 49.6, and 32.9% respectively. However, these parameters decreased with doses > 2 g·kg-1. Significant linear correlations were observed between the concentrations of micronutrients in wheat grains and those present in the soil. The bioconcentration factor increased but remained below 1. This research reveals that TMT are perfectly suitable to fertilize wheat using doses<1 g·kg-1, ensuring safe application for the environment and human health. Through this research, it was demonstrated that within certain thresholds, TMT can enhance the mineral nutrition of plants as well as positively impact agricultural productivity and product quality. These results can be replicated in other regions worldwide by adhering to the described procedure.

Allelochemicals have emerged as an important player in inducing the abiotic stress tolerance. The experiment included three components: different levels of salinity stress (SS: control, 6 dS m-1, 12 dS m-1), seed priming with moringa leaf extract (MLE: 0.5%, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%), and saltwater-tolerant and salinity-sensitive wheat cultivars (Faisalabad-2008, Galaxy-2013). Results showed that salinity lowered photosynthetic pigments, photosynthesis, transpiration, internal carbon, and stomatal conductance while causing poor and delayed germination, inconsistent seedling growth, and increased hydrogen peroxide accumulation. However, hydro-priming and MLE priming enhanced emergence dynamics, growth, biochemical and enzymatic characteristics, and physiological aspects. The cultivar Faisalabad-2008 (wheat) performed well, but at high salinity levels, the hormetic impact of moringa leaf extract was more obvious, enhancing the germination and growth of cultivar Galaxy-2013, which was salinity-sensitive. Wheat cultivars’ germination and seedling growth improved most when primed with 2% MLE (Faisalabad-2008) and 2.5% MLE (Galaxy-2013). This demonstrated that moringa possesses growthpromoting compounds that efficiently mitigate the toxic impacts of salinity.

Given the challenges posed by climate change and population growth, Iraq faces increasing demands for food production and water resources. To enhance agricultural productivity and optimize water management for crop efficiency, this study evaluated various wheat varieties, specifically Mawaddah, Bohuth 10, Aba99, and Babel113, under different irrigation level. These level were based on depletion levels of available water at 40%, 55%, and 70%. Key metrics measured included actual evapotranspiration, water use efficiency (WUE), grain yield, spike number, grains per spike, and the weight of 100 grains over the growing seasons of 2022–2023 and 2023–2024. The findings revealed that water consumption varied with depletion levels for all wheat varieties, amounting to 435.53, 397.13, and 365.13 mm season-1, and 465.7, 422.10, and 385.40 mm season-1 for the respective depletion levels of 40%, 55%, and 70%, across the two seasons. WUE ranged from 1.01 for Babel 113 at the 70% depletion level to 1.85 for Bohuth and Mawaddah at the 40% depletion level. Among the plant traits, Mawaddah had the best performance at the 40% depletion level, while Babel113 had the lowest performance at the 75% depletion level. The drought sensitivity index varied among the varieties due to their genetic differences. Our research supports the feasibility of utilizing water at depletion levels up to 75% when cultivating drought-tolerant wheat varieties in semi-arid and arid conditions.

The purpose of the study is the determination of heavy metals in soil samples and their circulation in the food chain. In this study, the correlation between the presence of heavy metals in agricultural soils and the quality preservation of wheat, specifically Triticum Aestivum and Triticum Durum, was investigated. The results indicate that over 85% of the samples contain a high presence of metals compared to Kosovar standards. Land surveying was conducted at distances ranging from 20 m to 400 m from the highway. The results for Pb at a distance from 20 m showed a value of 2.11 mg·kg-1, while Zn varied with a value of 5.12 mg·kg-1. However, the amount of heavy metals in agricultural soil is not sufficient to determine their risk in the food chain. The samples studied from the wheat varieties exhibited the accumulation of metals in the wheat cultivated in the studied soils. Some wheat samples showed high levels of heavy metals, with Pb varying significantly with a value of 1.99 mg·kg-1, and Cr with a value of 6.12 mg·kg-1. In this study, the circulation of soil metals such as Pb, Cd, Cr, Fe, Cu, Zn, and Mn was monitored. The study then continued with the monitoring of soil physicochemical parameters as indicators of soil quality, such as organic carbon. The results showed variations depending on the distance and its concentration. The maximum protein value varied at 11.9%, gluten at 22.8%, moisture at 11.4%, etc., especially for Triticum E. and Triticum D. wheat varieties.

The article experimentally established the influence of amplitude, frequency and duration of processing on the efficiency of vibratory wetting of wheat. With increasing amplitude and frequency of oscillations, as well as the duration of processing, the increase in moisture in the grain increases nonlinearly. With oscillation amplitudes of 10 and 20 mm and constant frequency of 10 Hz and processing duration of 8 min., Wheat grain increased moisture by 2.1%. Processing time more than 8 min. does not increase the moisture content of wheat. The largest increase in moisture in wheat was observed at an oscillation frequency of 12 Hz and an amplitude of 20 mm and a treatment duration of 5 min. Increasing the oscillation frequency more than 12 Hz did not lead to an increase in wheat moisture. It was found that the load does not affect the efficiency of moistening wheat grain.

This study was carried out to show the extent to which the land is productive due to the effect that climatic changes and the increase in population growth are the reasons that led to an increase in the demand for food, especially in developing countries. Therefore, a scientific way must assess the land suitability for growing crops. This research aimed to provide an integrated approach to the process of analyzing the suitability of agricultural lands for crop growth. Wheat in the Nile region of Babylon Governorate, was studied using the analytical hierarchy model (AHP) and compared with the parametric method and the actual crop in the field, as twelve soil criteria were determined (electrical conductivity, soil interaction, cation exchange capacity, exchangeable sodium ratio, soil texture, lime, gypsum, organic carbon, drainage, soil depth, slope, flooding) and three criteria were added in the AHP method due to their importance in Iraqi soils, which are (total nitrogen, availability phosphorus, crop variety). The results were extracted and showed that all the results of the study using the parametric method within the very unsuitable class for cultivation, N2, 72.5%, with an area of 37,734.07 hectares, and the unsuitable class, N1, 27.5%, with an area of 14,312.92 hectares, either by using the method. According to the analytical hierarchy process and giving varying importance to the soil criteria above, it was found that 37.5% are very suitable S1 with an area of 19517.62 hectares, 42.5% suitable for agriculture S2 with an area of 22119.97 hectares, and 20% moderately suitable S3 with an area of 10409.4 hectares. These results were similar to the agricultural reality of the regions under study.

In Morocco, the intensive use of agricultural land coupled with irregular precipitation is a serious threat to the country’s food security. Conservation agriculture especially no-tillage (NT) system has shown an important result in the semi-arid regions of Morocco, but its dissemination to other, more humid, agro-ecological zones (precipitation > 350 mm) is still low. For this purpose, a field experiment under NT system has been installed since 2004 in the Zaer Plateau (Central Morocco) to study the adaptation of this system to the irregular rainfall compared to a conventional tillage (CT). Yields (grain and biomass) of crops (wheat and lentil) under NT and CT were analyzed and compared over the years of study. The ANOVA test showed that yields over the seven years were significantly different and that both crop yields under NT system were greater than or equal to those under CT system even though lentil is more vulnerable to extreme climate events under CT and NT systems. Unlike NT, yields under CT were significantly correlated with the rainfall amount received during the crop cycle. This indicates the dependence of CT precipitation, whereas NT is more adaptable to the irregularities of the climate in the study area.

The level of wheat grain contamination with lead and cadmium was determined using electrothermal atomic absorption spectrometry with Zeeman background correction (ETAAS) after microwave digestion. The obtained limits of quantification were 0.001 mg∙kg-1, for both metals. A total of 300 samples of wheat grain from agricultural regions of Poland were examined, 150 each from the two consecutive harvest years 2017 and 2018. None of the tested samples exceeded the maximum level of these metals, as specified in the European regulations. The contents of lead and cadmium in wheat grain from both years of harvest ranged from <0.001 to 0.098 mg∙kg-1 and from 0.006 to 0.098 mg∙kg-1, respectively. Despite similar ranges of these metals, the highest lead contents were two times lower than the maximum limit value, while the highest cadmium contents were close to it. As for lead, a significantly higher (p < 0.05) mean content of this metal was found in wheat grain from the 2018 harvest compared to 2017 and in the western compared to eastern regions of the country. However, the cadmium contents did not differ significantly between the two harvest years, but were significantly higher (p < 0.05) in wheat grain from the southern regions compared to northern regions of Poland. Additionally, the highest contents of cadmium, close to the maximum limit, were found in the South-West region and in the both years of harvest. The risk analysis of the occurrence of the excessive contents of toxic metals in wheat grain showed a low risk level for lead in all investigated regions, and a medium level for cadmium, in general.

The world’s noticeable population growth is associated with an increased demand for agricultural products. The search for new solutions to increase crop productivity while ensuring environmental stability is becoming a key role. One such method is the use of the biopreparations containing Effective Microorganisms. EM consist of about 80 species of selected aerobic and anaerobic microorganisms, which have the ability to restore the biological balance. Professor Teruo Higa of Ryukyus University in Okinawa is the creator of Effective Microorganisms. When added to agricultural ecosystems they stimulate plant growth, improve the condition of soils affected by excessive use of chemical fertilizers allowing insoluble forms of elements to be transformed into plant-available forms and protect them from certain diseases and pests. This solution is an ecological alternative to conventional technologies and does not further pollute the ecosystem, which is crucial. Organic fertilizers in the form of EMs are made using live microorganisms they do not only deliver nutrients to the soil but also allow inactive ones to become available. With improved nutrient uptake and protection from soil pathogens, plants develop and grow better for improved yields. They contain organic matter and one or more biologically active organic compounds (amino acids, vitamins) as well as macroand microelements that stimulate plant growth and development. They provide plants with essential substances, which are naturally synthesized in many complex biochemical processes, causing energy savings that can be used for other transformations in the plant.

This research aimed to determine the physicochemical characteristics and heavy metal concentrations of agricultural soils used for grape and wheat production in Morocco in the Mohammedia Benslimane area. The organic matter (OM) content ranged from 0.6% to 2.93%. The degree of total nitrogen was higher in the wheat plots than in the vine plots in the Mohammedia and Benslimane regions. Total nitrogen average rates ranged from 0.04 to 0.5% and from 0.07 to 0.8% in the vine and wheat plots. These results imply that the soil was silty clay and clay texture, neutral to slightly acidic at all stations. The P2O5 concentrations were 11.15 ppm and 68.14 ppm under the vine and the wheat plots, respectively, while the potassium concentration ranged from 33.1 to 287.9 ppm and from 26.9 to 184.75 ppm under the vine and the wheat plots, respectively. Furthermore, the concentrations of Cd at a few stations exceeded the standard value (2 ppm), reaching 10.375 ppm. The Pb and Zn concentrations were higher in vineyard plots than in wheat plots. The Pb and Zn concentrations were 20.22 ppm and 148.60 ppm, respectively. This study reports updated information on the states of eight stations in Mohammedia and Benslimane. However, further research is necessary to determine the pollution factors in local practice crops and naturally growing plants at these stations to assess their impact on livestock and humans.

The COVID-19 outbreak has seriously affected the global food security at a time when it was significantly compromised by the effects of climate change and armed conflicts. The impact of the pandemic and quarantine restrictions imposed in response to the deadly virus brought humanity face-to-face with a new threat – that of food insecurity – which contributed to a high social demand for state-of-the-art methods of improving the cereal production efficiency. The aim of the study is to develop and implement a methodological approach to enhancing the cereal production efficiency. The methodology of the study relies on time series that made it possible to determine the main trends in regional cereal production and make projections. Application of the suggested approach in the Kostanay region revealed that this region was among the key cereal producers in the country. In 2019, the region was affected by extreme weather, which caused a sharp decline in cereal production. The present study, however, projects large opportunities for cereal production growth in the region and a significant increase in cereal production in the future. In addition, the paper suggests the following action plan to improve efficiency of the cereal production sector in the Kostanay region: streamlining of state support arrangements for cereal producers; development of affordable crop insurance products; systemic steps to increase cereal yields; development of logistic infrastructure; comprehensive monitoring of cereal production to develop a system of rapid response to changes in the external environment.

Concentrations of heavy metals in the soil such as: (Pb, Cd, Zn and Cr), play a role in contamination of agricultural crops such as wheat (Triticum aestivum L.). Roads in the Republic of Kosovo are congested with traffic; in addition, over 55% are more than 20 years old. The agricultural land near roads in Kosovo is cultivated with agricultural products, especially wheat. This study aimed to investigate the concentration of toxic metals in soil and wheat crops due to vehicle emissions. In this research are examined the physico-chemical factors that affect the mobility of metals in the soil of the research area as; pH, concentration of organic carbon and heavy metals such as: (Pb, Cd, Zn and Cr). Analytical research shows that the content of toxic metals decreases with increasing distance or along highways. The concentration tests of toxic metals near roads and lands planted with analyzed agricultural crop of corn showed that heavy metal deposits also depend on atmospheric conditions and emissions from vehicle traffic.

In this research, estimation potential of Aquacrop model under deficit irrigation and salinity conditions were evaluated for winter wheat grown under arid and semi-arid climates. Five different irrigation strategies and irrigation water salinity levels (0.5, 5, 7.5, 10, 15 dS m-1 ) were taken with the model to estimate deficit irrigation and salinity scenarios. Wheat grain yield, biomass production and canopy cover were simulated under deficit and salinity stresses. According to estimation of the model; the deficit irrigation with water reduction of more than 75 % of full irrigation was applied at growth stages of wheat, revealed the significant reduction in grain yield, biomass and canopy cover as compared with full irrigation practice. The increase in irrigation water salinity caused a significant decrease in grain yield and biomass value. It was compared to the 0.5 dS m-1 salinity level, a low value of 3% was obtained for the 5 dS m-1 salinity level. Yield loss of 7.5, 10 and 15 dS m-1 salinity levels were found to be 18.97%, 42.5% and 85.6% respectively. Also, increasing irrigation water depth in saline treatments resulted in increased grain and biomass yield. For sustainable water management in agriculture area, using simulation model such as Aquacrop is useful tolls to estimate effect of applied water depth and quality of irrigation water on crop yield.
