Résumé :

Barley is cultivated for food, technical and feed purposes. Barley grain is used for barley flour, pearl barley and a number of products, from which are prepared for our nutrition. In addition, it is used for the preparation of coffee substitutes, in the alcohol and brewing industries, has high feed qualities and is widely used as a concentrated feed for all types of farm animals, especially pigs. The results of studies showed that the dynamics of plant density and root rot damage were more influenced by planting rates, less than the estimated dose of fertilizers. The best nutritional regime and the maximum barley productivity (4.06 tons per hectare) with good grain quality indicators were obtained against the calculated nutritional background (4.0 tons per hectare) with a sowing rate of 5 mln. germinating seeds per 1 ha. The two-factor field experience with serial distribution of plots was laid on leached chernozem in LLC AF “Zay” of Zainsky district of the Republic of Tatarstan in 2013-2015. The purpose of the research was to study the biological characteristics of the variety and soil and climatic conditions for yield and quality indicators of barley grain. The objectives of our research were: to determine the effect of the seeding rate on the density of the stalk, damage to plants by root rot, the dynamics of plant nutrients, weediness of crops, yield and quality of barley grain. In the course of our studies, we found that the minimum value of barley grain quality indicators was observed against the background without fertilizers when sowing 5.5 million units per hectare: nature was 620 g/l, filmy 9.4%, germination 96.8%, the protein content of 11.9% and the extractivity of 77.0%, the maximum against this background was observed when sowing 4.0 million units per hectare. The barley grain quality indicators, grown against a calculated nutritional background, may well correspond to the brewing industry. The formation dynamics of plant densities and affection with their root rot had a greater influence on planting rates, and less calculated doses of fertilizers.

Résumé :

Summary Salinity is an agricultural and eco-environmental problem worldwide that decreases crop production. Endophytic fungi have been shown to improve plant tolerance to stressful conditions. The purpose of the paper is to examine the efficiency of Embellisia phragmospora, Fusarium equiseti and Fusarium graminearum to improve tolerance of pot-grown barley in greenhouse under different levels of soil salinity (2.5, 8 and 14dS/m) by estimating growth, relative water content, mineral nutrition, photosynthetic pigments biosynthesis, proline and sugar levels. Results showed that E. phragmospora increased barley emergence rate to 66.7% compared to 60% recorded by non-colonized barley under 14dS/m soil salinity. The tested endophytes increased barley root length, shoot and root dry weights under salt stress. Endophytic fungi reduced Na+ accumulation and improved K+ uptake in barely under salinity. Fusarium equiseti and F. graminearum-inoculated barley increased proline content under salinity. Fusarium graminearum-colonized barley showed the highest sugar content under salt stress. Our findings demonstrate the feasibility of endophytic fungi bio-inoculation in improvement of barley tolerance to salt stress, which qualify them to be a potent tool to provide substantial benefits to crops for sustainable agriculture.

Résumé :

Underutilized grain crops are an essential part of the food system that supports humankind. A number of these crops can be found in China, such as barley, buckwheat, broomcorn millet, foxtail millet, oat, and sorghum, which have characteristics such as containing more nutritional elements, being resistant to biotic and abiotic stresses, and having strong adaptability to poor environments. The diversity of these crops provides options for farmers’ livelihoods and healthy food for the population. Although some mentioned crops such as barley, oat, and sorghum are not underutilized crops globally, they could be considered underutilized in China as they were more important in the past and could be revitalized for food and nutrition in the future. This paper reviews current progress in research and development in the areas of germplasm resource conservation, variety improvement, cultivation technologies, processing, and the nutrition and benefits of six underutilized grain crops in China. It is concluded that underutilized grain crops could play a critical role in food and nutritional security in China.

Résumé :

Cereals in nutrition provide the energy necessary for daily functions and usual metabolic processes. Apart from being used as basic raw material in beer and whisky production, barley is more often used in baking industry through fortifying wheat products or through complete replacement of wheat flour with barley flour. Triticum monococcum L. is a wild wheat whose interest for cultivation rises due to dietetic nutritive aspects of this particular type of wheat, mainly because of the important role in preventing cancer, diabetes and chronic diseases. The aim of this abstract is to assess the knowledge and attitudes of consumers in the Republic of Macedonia and the Republic of Bulgaria regarding the consumption of cereals in daily nutrition and products from different cereals.

Résumé :

The article presents the results of studies of the influence of mineral fertilizers on the yield of winter barley in the Western Forest-Steppe. It has been found that grain yield depends on providing plants with mineral nutrients throughout the growing season. The results of scientific research on the influence of mineral nutrition on seed germination, plant survival during the growing season, grain yield and structure of winter barley cultivated on gray podzolic soils in the Western Forest-Steppe are described. The authors of the research studied different doses of mineral fertilizers: 1) without fertilizers (control); 2) N30Р30К30; 3) N60Р60К60; 4) N90Р90К90. A decrease in field germination by 1.1–2.3 %, with an increase in the level of mineral nutrition was determined. The positive effect of mineral fertilization on the survival of winter barley has been proved. The lowest level of plant survival was in the areas without fertilizers, and the highest – under application of mineral fertilizers in the norm N90Р90К90. The positive effect of fertilization on the number of productive stems, the weight of grain from the ear and the number of grains in the ear was demonstrated. A positive correlation was established between fertilizer and the number of grains in the ear (r = 0.96) and fertilizer and grain weight from the ear (r = 0.77). It was found that the studied rates of fertilizers were effective for the nutritional regime of winter barley agrocenosis in the Western Forest-Steppe. The optimal dose of fertilizers which ensures maximum grain yield was determined. Application of phosphorus and potassium fertilizers (Р90К90) for plowing and nitrogen (N30+30+30) in three steps: during the restoration of spring vegetation, in the phase of tube emergence and earing provided a significant increase in yield as compared to control (without fertilizers) and options N30Р30К30 and N60Р60К60.

Résumé :

The effects of suppressing couch grass (Elytrigia repens L.), through integrated management, on soil biological quality and N and P nutrition of barley (Hordeum vulgare L.) were evaluated in a field experiment (1987–92) on a Dark Grey soil in Alberta, Canada. The management practices consisted of combinations of herbicide application, crop rotations and tillage treatments. The 3-year crop sequences consisted of continuous barley, canola (Brassica rapa L.)–barley–barley, fallow–barley–barley, and barley or canola undersown with red clover (Trifolium pratense L.)–red clover green manure–barley. In 1992, the sixth year of the experiment, soil and plant samples were analysed for nutrient content. Treatments that consisted of spring and autumn tillage only did not suppress couch grass and produced low barley yields and N and P uptake. More N was immobilized in couch grass shoots and rhizomes and soil microbial biomass with these treatments than with similar herbicide-treated crop rotations. Tillage-plus-herbicide treatments effectively suppressed couch grass and enabled the barley crop to compete for soil N, however, both spring and autumn tillage were required for weed control. The fallow treatment impaired soil quality by reducing soil and microbial C and N, but produced similar barley yields as continuous cropping with tillage-plus-chemical control. Red clover ploughed in for green manure enhanced soil quality indicators such as soil and microbial biomass C, total and mineralizable soil N, and microbial N, but did not increase barley yield compared to continuous grain cropping.

Résumé :

The aim of the study was to determine the dependence of brewing quality of spring barley grain in terms of indicator of Kolbach number depending on the eff ect of foliar nutrition of plants during the growing season with micronutrients Wuxal on different backgrounds of mineral fertilization. Effectiveness of the infl uence of foliar nutrition of spring barley plants by microfertilizers Wuxal during the growing season on the brewing quality according to the Kolbach number was established. It is revealed that the eff ectiveness of the technological agricultural measure carried out depends on the number of agri-receptions, the rate of microfertilizers and the background of mineral nutrition. It was proved that when growing barley on the background of mineral nutrition N30P45K45 the best results were obtained with two and three times application of microfertilizers at the rate of 1.5 l/ha in accordance with the phenophases of tillering, stem elongation and fl owering. Maximum productivity on the background of N60P90K90 mineral nutrition is achieved by providing three times of crops spraying with a solution of microfertilizers in the amount of 2.0 l/ha each time in accordance with the above-mentioned phenophases of barley plants growth and development. The efficiency of foliar nutrition of spring barley plants by microfertilizers depends on the technological scheme of application, namely on the number of methods of the agro-measure carried out at the respective phenophases of development. The variants of double application microfertilizers were the best in growing barley on the background of mineral nutrition N30P45K45, – Wuxal P Max 1.5 l/ha during tillering and Wuxal Grain 1.5 l/ha at the beginning of flowering; Wuxal Grain 1.5 l/ha during the stem elongation and Wuxal Grain 1.5 l/ ha at the beginning of flowering. The optimal variant for three-times foliar nutrition of plants with microfertilizers was as follows: Wuxal P Max 1.5 l/ha during tillering, Wuxal Grain 1.5 l/ha during of stem elongation and Wuxal Grain 1.5 l/ha at the beginning of flowering, where the highest Kolbach number is obtained – 47.7; 47.5 and 48.0 %, respectively. On the background of N60P90K90 mineral nutrition, the highest parameters were established for three-time spraying of plants with microfertilizers Wuxal P Max 2.0 l/ha during tillering, Wuxal Grain 2.0 l/ha during of stem elongation and Wuxal Grain 2.0 l/ha at the beginning of flowering – 46.9 %. Key words: spring barley, grain quality, Kolbach number, microfertilizers, foliar nutrition.

Résumé :

The nutritional composition, polyphenol and anthocyanin composition, and antioxidant capacity of 52 colored highland barley were evaluated. The results showed that the protein content of highland barley in the black group was the highest, the total starch and fat contents in the blue group were the highest, the amylose content in the purple group was quite high, the fiber content in the yellow group was quite high, and the β-glucan content of the dark highland barley (purple, blue and black) was quite high. The polyphenol content and its antioxidant capacity in the black group were the highest, while the anthocyanin content and its antioxidant capacity in the purple highland barley were the highest. Ten types of monomeric phenolic substances were the main contributors to DPPH, ABTS, and FRAP antioxidant capacity. All varieties could be divided into four categories according to nutrition or function. The grain color could not be used as an absolute index to evaluate the quality of highland barley, and the important influence of variety on the quality of highland barley also needed to be considered. In actual production, suitable raw materials must be selected according to the processing purpose and variety characteristics of highland barley.

Résumé :

Barley (Hordeum vulgare) is one of the oldest domesticated crops used for both human and animal feed. Over the years however, its role in human diet has been very limited and replaced by the broad use of wheat products. Nowadays, micronutrient deficiency, also known as hidden hunger, is one of the major challenges to human health worldwide. Biofortification of staple crops has been broadly accepted as the best strategy to overcome these limitations. Studies on the nutritional value of barley have proven its multiple benefits on human health and drove new attention towards the cultivation under the light of new food purposes. Biofortification of barley is approached through agronomic practices, conventional breeding, and/or the use of biotechnological tools and research results show that barley can be a promising crop for the emergence of novel food products with a significant impact on human nutrition.

Résumé :

The protein concentration of cereal grains is low and the production of cereal crops with increased grain protein concentrations is desirable. This work investigates the physiological aspects of protein accumulation potential in barley grain. A recently developed perfusion system was used in four experiments conducted in 1993 and 1994. In the field experiment, plants were allowed to take up urea at 15 or 30 mM N, or ethephon at 15 $ mu$ M. Abscisic acid and 2,4-D decreased total seed weight spike$ sp{-1}$. Gibberellic acid and 2,4-D increased seed protein concentration and content, while ABA decreased both of these. Kinetin and abscisic acid treatments resulted in the highest and lowest levels, respectively for flag leaf photosynthesis, stomatal conductance, transpiration and intercellular CO$ sb2$ concentration. Both protein content spike$ sp{-1}$ and seed protein concentration were elevated in plants fertilized with 10.7 mM N via the soil and plants perfused with 30 mM N via the peduncle. Plants receiving treatments of 10.7 mM N from the soil and mixture of 30 mM N and GA$ sb3$ or 2,4-D through the peduncle had increased protein content seed$ sp{-1}$, and the highest seed weight spike$ sp{-1}$, respectively. Peduncle perfusion with 30 mM N increased spike protein concentration and content and grain protein concentration without affecting seed weight spike$ sp{-1}$. Grain protein concentration was increased by peduncle perfusion with ethephon. The perfusion technique worked well under field conditions. (Abstract shortened by UMI.)

Résumé :

Absorption and utilization of N by plants has been shown to be affected by the N form supplied and salinity. This study was conducted to determine the growth and N uptake of barley grown in modified Hoagland-Arnon nutrient solution containing different NH₄⁺-N / NO₃⁻-N ratios and various salinity levels in the growth chamber. The first experiment was conducted to study the N uptake rate at five different NH₄⁺-N/NO₃⁻-N ratios and three salinity levels (0, 6 and 12 bars). No ¹⁵N was applied in this experiment. The second experiment was conducted with the same objectives with modification in the salinity levels based upon the results of experiment 1. The salinity levels were 0 and 8 bars. The third experiment was similar to the second experiment except the duration of the study that was 45 days instead of 30 days. The NH₄⁺-N/NO₃⁻-N ratios were 0/100, 25/75, 50/50, 75/25 and 100/0. The total N concentration in all treatments was 100 ppm. Solutions were sampled after every 15 days during all experiments and analyzed for ammonium and nitrate concentration. For the short term ¹⁵N uptake study (experiments 2 and 3), either ammonium labelled ¹⁵N or nitrate labelled ¹⁵N was added to each NH₄⁺-N/NO₃⁻-N treatment for 6, 12, and 24 hours period on the last day of experiment 2 and 6, 12, and 18 hours period on the last day of experiment 3. Mixed N nutrition resulted in greater accumulation of whole plant-N than plants receiving only NO₃⁻ or NH₄⁺ as the source of N. Labelled nitrate recovery was highest in the 50% NH₄⁺ treatment. The same trend was evident from the solution sample analysis. In all the three experiments, plants produced significantly higher dry matter yields when grown with mixed N nutrition than with NH₄⁺ or NO₃⁻ alone. Total dry matter production, nitrogen uptake, root and shoot N contents, ¹⁵N content and water uptake decreased with increasing salinity levels in all the three experiments. The plants fed with ¹⁵NO₃⁻ source inhibited nitrate uptake more severally under saline conditions than the NH₄⁺-fed plants under similar conditions. Salinity and N nutrition interaction was found significant in all experiments.

Résumé :

In recent years llamas have attracted great national and international interest for their qualities of human food production, fiber production for high-quality textiles, and for being an ecological animal. These qualities have allowed a resurgence of cultivating them for commercial ends. One of the principal limits is secure food for allowing a constant, sustainable growth. The objective of this study was to evaluate the metabolic profile and live weight of male llamas (Lama glama) fed with barley hay, alfalfa hay, and quinoa scrub. The fieldwork occurred in metabolic chambers in a closed environment at the demonstration farm of the Benson Agriculture and Food Institute (of Brigham Young University) located in the community of Letanys, in Viacha municipality. Three types of food--100% barley hay, 80% barley hay + 20% alfalfa hay, and 80% barley hay + 20% quinoa scrub--were offered randomly to seven llamas averaging three years old. A channel allowed the placement of a one-meter probe that collected jugular blood, the plasma of which was analyzed in the animal nutrition laboratory of UAC-Tiahuanaco. The average metabolites in the blood plasma were not significantly different (p>0.05) according to treatment except for GPT enzyme, with CV=20.5 Weight gain showed no significant difference (p>0.05) between treatments nor between blocks. Regarding percentage of food absorbed, 90% was consumed and 64% was absorbed. It was found that animals subjected to the three different diets lost weight due to the stressful experimental conditions of physiologic administration of saline and heparine during sample collection. In conclusion, the recommended feed is the diet consisting of barley hay and quinoa, followed by barley hay and alfalfa, both of which are recommended to supplement the feeding of llamas. Also, animals with better physical constitution and a tranquil temperament respond best to the treatments.

Résumé :

[Truncated abstract] Zinc deficiency in crops is the most widespread micronutrient deficiency, with about 50% of the cereal-growing areas worldwide containing low levels of plant-available Zn. Zinc plays multiple key roles in different metabolic and physiological processes; its deficiency in crops reduces not only grain yield, but also the nutritional quality of grains. Insufficient micronutrient intake, particularly Zn and Fe, afflicts over 3 billion people in the world, mainly in developing countries. Increasing the amount of Zn in food crops can contribute to improving the Zn status of people. Furthermore, Zn-dense seeds have agronomic benefits, resulting in greater seedling vigour, bigger root system and higher crop yield when sowed to soils with low plant-available Zn. Enhancing nutrient content and nutritional quality of crops for human nutrition is a global challenge currently, but it was mostly ignored during the breeding process in the past. There is a significant genotypic variation for seed Zn accumulation in several crops (including barley) which could be exploited in the breeding programs to produce genotypes with higher seed Zn concentration and content. However, the progress in Zn efficiency until now has mainly relied on conventional plant breeding approaches that have had limited success. Therefore, reliable alternative methods are required. Enhancing mineral nutrition through plant biotechnology may be a sustainable and beneficial approach in developing Zn-dense seeds in the staple crops. ... This DNA band was sequenced and converted into a simple sequence-specific PCR-based marker, which was designated as SZnR1 (seed Zn-regulator1). The developed marker is very easy to score, is inexpensive to run and amenable for a large number of plant samples. The successful development of SZnR1 molecular marker linked to chromosome region associated with seed Zn concentration and content using MFLP in this study illustrates the advantage of this technique over some other DNA fingerprinting methods used for identification of molecular markers for marker-assisted selection (MAS). In conclusion, the greater Zn efficiency of Sahara over Clipper under sufficient Zn supply may be attributed to its higher uptake of Zn. It appears that soil-based pot experiments under controlled condition may offer potential improvements over field experiments in screening for seed Zn accumulation. Shoot and seed Zn concentration and content can be used to diagnose the Zn statues of barley genotypes, and may be a useful selection criterion for Zn efficiency in large populations like doubled-haploid populations aimed at developing molecular markers for Zn efficiency. Identified QTLs influencing seed Zn concentration were repeatable in the field and glasshouse conditions, suggesting their robustness across environments as well as their value in marker-assisted selection. The developed PCR-based marker SZnR1 and other molecular markers associated with the QTLs on the short and long arms of chromosome 2H have the potential to be used for marker-assisted selection in breeding for Zn-dense seed in barley.

Résumé :

The Highlands of Bolivia present a great diversity of native botanical species with strong forage characteristics, providing them with a considerable potential for usage as a resource in the feeding of cattle. The following work was performed with the idea of taking advantage of the zone’s native species as a source for the feeding of llama cattle. In order to accomplish it, we took into consideration the following variables: food consumption, water consumption, amount of fecal excretions, urine volume, body weight, and the digestibility of the nutrients found in the food prepared with paja brava and barley (ash, protein, fiber, and total digestibles). The experiments were conducted in metabolic cages for 30 days; with 4 llamas of the K’ara breeds, between the ages of 4 and 5 years old, and an average weight in between 105 and 125 kg of life weight. The statistical analysis was conducted using a completely random cross test. We concluded barley and paja brava in their natural state are forage species which nutrient composition does not allow optimal development in llamas.

Résumé :

One of the modern techniques of improving microbial preparations efficiency is a combination of several microorganisms with different beneficial properties in one inoculant. Taking into account the role of nitrogen and potassium nutrition and their synergism, it is essential to develop preparations of N2-fixing and K-mobilizing rhizobacteria, especially Azospirillum sp. and Bacillus sp. Effective biological control of root infections is of great importance in order to prevent crop yield losses. Among soil antagonistic fungi, Trichoderma sp. is the most promising one. Microbial inoculant includes three components: Azospirillum brasilеnse 2(b)3 + Bacillus circulans K-81 + Trichoderma longibrachiatum L-7 (1:1:1). Combined application of rhizobacteria A. brasilense + B. сirculans induced significant hormonal effect. Roots dry mass increased by 28%, roots length per plant – by 25%, stem dry mass – by 33%. In the field experiment, the treatment of barley by microbial inoculant provided the reduction of root rot incidence by 52.0–58.0%, disease development (waxy ripeness) – by 2.6–2.9 times, biological efficiency was 66.3–69.5%. Treatment of winter rye resulted in the reduction of disease incidence by 42.4–45.0%, disease development (milky ripeness) – by 2.0–2.6 times, biological efficiency – 50.2–61.2% according to soil-erosion catena. Beneficial influence of inoculation on plant development and nutrition, as well as effective biological control of plant diseases, provided significant crop responses: for winter rye – 3.8-4.5 c ha-1 or 7.0% - 9.8%, for spring barley – 5,2 – 4.9 c ha-1 or 9.3% – 9.2% according to soil-erosion catena. Microbial inoculant exhibits the properties of plant growth promoter, biological fertilizer, and biological fungicide.

Résumé :

Feeds and animal nutrition presents a major sector in providing food security. However, there is a large gap between fodder supply and demand [1]. This gap can be attributed basically to climatic changes, urbanization and increase in meat demand. Nowadays, especially after the covid-19 pandemic, there is a crucial problem in supplying fresh green feed to remote and urban regions. Hydroponic fodder is an alternative solution to provide the sustainability of quality forage for ruminant. Hydroponics can include several crops such as maize, wheat and barley, the fodder can be produced in a short duration (6-10 days) and all year around. The hydroponics fodder present various benefits for animal health. Feeding hydroponically produced fodder increases the digestibility of the nutrients in the ration, which could increase milk production [2]. Hydroponic fodder production is an economic solution particularly where the conventional production of green fodder is limited or unavailable. This technology put forward a solution to address the shortage of forage production caused by the scarcity of green feed in dry seasons and urban areas [3]. That´s why, further studies and academic efforts are needed to expand hydroponic fodder production. The purpose of this study is to review the actual literature on hydroponic fodder production process, nutritious value and effects on livestock production and productivity.

Résumé :

One of the ways to maintain soil fertility is to use organic fertilizers. One of them can be straw of cereal crops (winter wheat and barley). However, the process of its decomposition can be delayed for several years. It is possible to accelerate the transformation process by using the native strain of cellulosolytic micromycete (Humicola fuscoatra VNIISS 016). Its introduction together with straw before plowing stabilizes agrophytocenosis. The experiments were carried out in laboratory under simulated conditions close to field ones. Scheme of the experiment: 1. Straw; 2. Straw + N (40 mg/4 g, which corresponds to 40 kg/ha); 3. Straw + N + H. fuscoatra + PC (nutritional supplement – molasses) (Kolesnikova M.V., 2014). As a result of the studies, it was established that winter wheat straw without additional components lost 0.86 g in weight (from the initial 4 g), 1.03 g when adding nitrogen fertilizer to the straw, and 1.49 g when using H. fuscoatra. We found that the addition of nitrogen to the straw stimulate the process of its transformation. Straw with nitrogen decompose faster than straw without any additives (by 41.5%). However, the addition of the native strain of micromycete accelerate the process by 48.3%. Barley straw lost 0.82 g in weight, straw with nitrogen fertilizer lost 1.06 g, straw and H. fuscoatra – 1.13 g. Further, the decomposition rate increased in the following row: straw → straw + N, where the speed was 26.7% higher → straw + N + H. fuscoatra, the decomposition rate is – 85.3% higher.

Texte intégral

Résumé :

Iron is the fourth most abundant element in the soil, but since it forms insoluble hydroxides at neutral and basic pH, it often falls short of meeting the basic requirements of plants and microorganisms. Most aerobic and facultative aerobic microorganisms possess a high-affinity Fe transport system in which siderophores are excreted and the consequent Fe complex is taken up via a cognate specific receptor and a transport pathway. The role of the siderophore in Fe uptake by plants and microorganisms was the focus of this study. In this research Rhizopus arrhizus was found to produce a novel siderophore named Rhizoferrin when grown under Fe deficiency. This compound was purified and its chemical structure was elucidated. Fe-Rhizoferrin was found to alleviate Fe deficiency when applied to several plants grown in nutrient solutions. It was concluded that Fe-Rhizoferrin is the most efficient Fe source for plants when compared with other among microbial siderophores known to date and its activity equals that of the most efficient synthetic commercial iron fertilizer-Fe EDDHA. Siderophores produced by several rhizosphere organisms including Rhizopus Pseudomonas were purified. Monoclonal antibodies were produced and used to develop a method for detection of the siderophores produced by plant-growth-promoting microorganisms in barley rhizosphere. The presence of an Fe-ferrichrome uptake in fluorescent Pseudomonas spp. was demonstrated, and its structural requirements were mapped in P. putida with the help of biomimetic ferrichrome analogs. Using competition experiments, it was shown that FOB, Cop B and FC share at least one common determinant in their uptake pathway. Since FC analogs did not affect FOB or Cop-mediated 55Fe uptake, it could be concluded that these siderophores make use of a different receptor(s) than FC. Therefore, recognition of Cop, FOB and FC proceeds through different receptors having different structural requirements. On the other hand, the phytosiderophores mugineic acid (MA and DMA), were utilized indirectly via ligand exchange by P. putida. Receptors from different biological systems seem to differ in their structural requirements for siderophore recognition and uptake. The design of genus- or species-specific drugs, probes or chemicals, along with an understanding of plant-microbe and microbe-microbe relationships as well as developing methods to detect siderophores using monoclonal antibodies are useful for manipulating the composition of the rhizosphere microbial population for better plant growth, Fe-nutrition and protection from diseases.

Résumé :

The COVID-19 pandemic has continued to affect agri-food systems around the world and lay bare its fragility, worsening the welfare of millions of smallholder farmers whose livelihoods are anchored on agricultural activities. For the vast majority of sub-Saharan Africa, COVID-19 has coincided with a number of other macroeconomic shocks, which have also exacerbated the impacts of the pandemic on food security, nutrition and general livelihoods, as well curtailed policy responses and mitigation strategies. In Zimbabwe, the COVID-19 pandemic struck at a time the country was experiencing a worsening economic and humanitarian situation. This study focused more on community and household dynamics and response measures to cope with the pandemic. This paper presents a summary of findings emerging from a series of rapid assessment studies undertaken by the Agricultural Policy Research in Africa (APRA) Programme in Mvurwi and Concession areas of Mazowe District in Zimbabwe to examine how COVID-19 is affecting food systems and rural livelihoods in our research communities.
