Profiles of Volatile Compounds from Seven New Hybrid Families Obtained by Crossings on Noir de Bourgogne Cultivar and Other Blackcurrant Varieties.

Berries of blackcurrant (Ribes nigrum L.) are popular for their strong and complex aroma and their benefits for health. In Burgundy (France), the most famous blackcurrant cultivar is the "Noir de Bourgogne". A blackcurrant breeding program was conducted to obtain new varieties, more resistant to infections and climate changes. The cultivar "Noir de Bourgogne" was crossed with seven other varieties in order to create a hybrid with good agronomic properties and organoleptic properties close to the ones of "Noir de Bourgogne". Several hybrids were created, and their aromatic profiles studied. Berries of eight cultivars, among which Noir de Bourgogne and hybrids resulting from crossings, were harvested during the summer of 2020. Volatile compounds of berries were analyzed by HS-SPME-GC-MS, and principal component analysis (PCA) was used as the most useful chemometric technique. The profiles in volatile compounds of hybrids were either different from those of the two parental varieties or close to that of varieties other than Bourgogne black. In all cases, the overall aroma strength of the hybrid did not equal that of the Noir de Bourgogne cultivar.

Invasive Wetland Weeds Derived Biochar Properties Affecting Soil Carbon Dynamics of South Indian Tropical Ultisol.

This study aimed to: (i) investigate the agronomic properties of biochars derived from selected invasive wetland weeds and (ii) examine the effect of biochar on soil organic carbon (SOC) dynamics and stability of tropical Ultisol soil. The biochars were analyzed for proximate properties, surface characteristics, elemental composition, functional groups, and thermal and carbon stability. Plant growth studies supplemented with biochar under greenhouse conditions for 1 year were conducted. The SOC, its fractions, and its dynamics were studied. The biochar incorporation significantly increased the SOC and its stable fractions like mineral Organic Carbon (MOC), fine-particulate organic carbon (fPOC), and Non-labile Carbon (NLC) by 24.54-7.82, 5.79-2.0, and 9.50-2.16 g kg-1 than control. The labile carbon fractions like Dissolved Organic Carbon (DOC), and coarse-Particulate Organic Carbon (cPOC) showed a substantial reduction by 0.72-0.26 and 2.92-1.29 g kg-1 respectively. However, the easily oxidizable carbon (EOC) and microbial biomass carbon (MBC) content increased by 2.10-4.87 g kg-1 and 28.33-158.55 mg kg-1 respectively. The addition of biochars resulted in the stabilization of soil aggregates. Likewise, substantial CO2 emission reduction (75.24-46.60%) has been achieved during the trials. The carbon pool management index (CPMI) values recorded a substantial increase of 40-7.2% between the trials. The findings imply that the inherent nature of weed biomasses determines the characteristics of the resulting biochar, and their application significantly influenced the carbon dynamics of the tropical Ultisol soil.

PROTECTION OF IRRIGATED AND NON-IRRIGATED AREAS FROM WATER EROSION

Today, one of the other agronomic properties of this type of soil is that the amount of total nitrogen in the soil depends on the amount of humus in the soil. its amount varies from 0.05% to 0.15%. Typical gray soils are a very favorable medium for nitrification. The main part of nitrogen is found in the soil in the form of nitrate and is in a form that is easily absorbed by the plant. In most cases, the amount of total phosphorus is greater than the amount of total nitrogen. And in the upper layers of the soil, it is 0.1%-0.2%. Typical irrigated gray soils contain a lot of remains of roots and other parts of the plant, relatively low soil compaction, and humus is present in the plowed part of the soil. These processes have a negative impact on soil fertility. The possibilities of application to modern production, analysis of solving problems, elimination of excess water loss are the main tasks of today in the region.

Frequency and spectrum of M2 mutants and genetic variability in cyto-agronomic characteristics of fenugreek induced by caffeine and sodium azide.

Trigonella foenum graecum L. (Fenugreek) is a valuable medicinal plant cultivated for decades for its therapeutic characteristics. Still no pronounced improvement concerning wild form was accomplished as it is a self-pollinating crop. Induced mutagenesis is encouraged as a remarkable tool on this plant to circumvent the genetic bottleneck of cultivated germplasms. As a result, novel allelomorphic combinations for short-term agronomic attributes were developed. Fenugreek cultivar Pusa Early Bunching, selected for the present experiment, was mutagenized with five doses (0.2%, 0.4%, 0.6%, 0.8%, and 1.0%) of caffeine and sodium azide (SA) to evaluate its impact on the qualitative and quantitative traits of M1 and M2 generation conducted in a Complete Randomized Block Design (CRBD), replicated five times during 2019-2020 and 2020-2021, respectively. The frequency of induced phenotypic variations was assessed in M2 progenies, resulting in the identification and isolation of a broad spectrum of mutants with altered phenotypes. Mutagenic effectiveness and efficiency were found to be maximum at lower concentrations of the mutagen treatments and highest in SA, followed by caffeine. Various morphological mutants with modified characters were observed at different concentrations in M2 generation. The spectrum of mutations was wider in SA than in caffeine, as caffeine produced 51 while SA produced 54 individual mutants under seven major categories. The maximum frequency of morphological mutants was associated with leaf, followed by plant size, plant growth habit, pod, seed size, seed shape, and seed color. Morphological and structural variations in the guard cells of stomata and seeds were observed through scanning electron microscopy. The variations created in the economically important traits may enrich the genetic diversity of this plant species. Moreover, these morphological mutants may serve as a source of elite genes in further breeding programs of fenugreek.

The Use of Genetic Material of Tall Wheatgrass to Protect Common Wheat from Septoria Blotch in Western Siberia

The Septoria blotch is one of the most economically harmful diseases of common wheat in Russia and the world. The disease is mainly caused by two pathogen species: Zymoseptoria tritici that damages the leaves, and Parastagonospora nodorum that strikes the leaves and ears. Resistance genes of the alien relatives are traditionally used for genetic defense of cultivars. The aims of the research were to study the resistance of the tall wheatgrass Thinopyrum ponticum (Podp.) Z.-W. Liu and R.-C. Wang and perspective introgressive lines of spring common wheat with its genetic material to Septoria blotch, and to characterize their agronomical properties to be used in breeding programs in Western Siberia. The studies were carried out in 2015–2019 in the field conditions of the southern forest-steppe (Omsk, Russia) on a natural infection background and according to standard methods. The Septoria diseases developed on the wheat in the period of milk-wax ripeness, independently of humid or dry weather conditions. In 2016, a sharp increase in leaf lesion was noted, probably associated with changes in the Z. tritici population. In 2017, the ratio of Z. tritici and P. nodorum was similar, and in 2019 Z. tritici prevailed. During the research, the lines that combined leaf and ear resistance to damage with high yield and grain quality were selected.

ПОЧВЕННЫЙ ПОКРОВ И СВОЙСТВА ПОЧВ МАЛЫХ ВОДОСБОРОВ ПРИДОНСКОГО МЕЛОВОГО ЛЕСОСТЕПНОГО РАЙОНА СРЕДНЕРУССКОЙ ВОЗВЫШЕННОСТИ

On the territory of the Pridonsky cretaceous forest-steppe region of the forest-steppe province of the Central Russian Upland, a large area is occupied by eroded soils and soils of gully-beam complexes. Various agrophytocenoses play an important role in the formation of erosion-accumulative processes. Soil flushing is common mainly in plowed areas. Denudation, deluvial and proluvial processes occur on the banks and bottoms of beams occupied by natural phytocenoses. The influence of anti-erosion forest belts on the intensity of erosion and soil accumulation is noted. Under the forest belts and on the adjacent sections of the slopes, washed and buried soils are formed. The features of the composition of the soil cover and soil properties according to the relief elements and phytocenoses of the beam catchment are noted. The proportion of soils exposed to the simultaneous effects of erosion and accumulation in the soil cover of the beam catchment is determined. The changes in the agronomic and physico-chemical properties of the soil under the influence of erosion-accumulative processes on the elements of the relief of the catchment area of the Log Repny and various land plots are studied. The change in the content of humus and the main elements of mineral nutrition of plants in the soils subject to these processes has been established. The taxonomic levels of the identification of signs of erosion and accumulation, depending on their intensity and nature, are clarified. The expediency of allocating the degree of soil flushing at the species level is shown. It is recommended to consider the signs of deluvial and denudation processes on the banks of the beam at the level of the soil type. Proposals have been developed to improve the classification of gully-beam soils.

SCS443 Isadora: cultivar de macieira de maturação tardia e de altíssimo potencial de conservação dos frutos

Abstract The objective of this study is to describe the agronomic attributes of the SCS443 Isadora apple tree cultivar and to highlight its potential use in Brazil. Obtained by the hybridization made at Epagri in 2001 between ‘Imperatriz’ and ‘Cripps Pink’, after 20 years of agronomic evaluations carried out in Caçador-SC and Fraiburgo-SC, ‘SCS443 Isadora’ was originated. This cultivar has a wide plasticity of adaptation to the southern Brazilian climate due to the medium chilling requirement to overcome dormancy. It has greater resistance to the main apple diseases than cv. Gala and fruit harvest is later than cv. Fuji. Its apples have a red skin and firm flesh (=18 lb), with high sugar content (= 14.5 %) and very crunchy and juicy texture, as well as high storage ability in post-harvesting. ‘SCS443 Isadora’ apples can be stored for 8 months, even in refrigerated air atmosphere chambers (21% O2) with inhibition of the ethylene response by the use of 1-methylcyclopropene (1-MCP). Even stored for long periods of time, the indices of quality loss, physiological disorders and fruit rotting in ‘SCS443 Isadora’ apples are lower than on Gala and Fuji apples.

СТРУКТУРНО-АГРЕГАТНЫЙ СОСТАВ РАЗНОВОЗРАСТНЫХ ЗАЛЕЖНЫХ ОСУШЕННЫХ ПОЧВ ЕВРЕЙСКОЙ АВТОНОМНОЙ ОБЛАСТИ

Involving new virgin soils in agricultural use requires huge capital investments and significant labor resources. The secondary return to agricultural use of fallow reclaimed lands not used in agriculture can become a less costly method of increasing the area of agricultural arable land. In the Middle Amur Lowland, the issues of environmental assessment of fallow drained soils, re-involved in agricultural use, remain poorly studied and practically there are no materials devoted to this issue. To study the ecological state of abandoned drained soils in the Jewish Autonomous region, the authors were carrying out a field research from July to September 2022. The studies showed that drained soils of agrocenoses after being out of agricultural use enter a complex process of self-healing. In fallow soils, the density of the top layer of soil decreases, which has a beneficial effect on the structure of the soil. With the fallow age increasing in drained meadow sod-gley soils, a decrease in the structure coefficient is observed to values close to the lower limit of “good” structure. In brown 20-year-old fallow mountain-forest soils it is observed a noticeable increase in the proportion of macro aggregates, including agronomically valuable ones, which indicates an improvement in the agronomic properties of fallow soils. The condition of the examined different age meadow gley soils deposits, which form the regional arable fund basis, makes it possible to classify them as suitable for agricultural use.

Effects of pyrolysis temperature and pressure on agronomic properties of biochar

This study focused on identifying the effect of pyrolysis temperature and pressure for lignocellulosic biomass on agronomic properties of biochar. For this purpose, two biomasses (vine shoots -VS and corn stover -CS) were pyrolyzed at different temperatures (350 and 500 °C) under different pressures (0.1 and 0.5 MPa) for a residence time of 60 min. Agronomic properties of biochars (including stability, pH, CEC, EC, bulk density, surface properties, and water holding capacity) were determined. Pyrolysis temperature impacted greatly on the biochar stability and the textural properties. The dependence of other properties of biochars on pressure and temperature varied as a function of the type of feedstock. In addition, the effects of pyrolysis temperature and pressure on 16 US EPA PAH concentration in biochar were also investigated. The PAH concentrations ranged between 0.822 and 5.112 mg kg−1. On average, VS-derived biochar had higher PAH concentrations than CS-derived one. The structural differences in biomass played a key role in determining the effect of pyrolysis conditions on total PAH concentration.

Response of Bread Wheat (Triticum aestivum L.) to Different Tillage Practices and Nitrogen Levels in a Clay Loam Soil

We can overcome this global challenge by minimizing input costs and optimizing yields by employing appropriate tillage techniques and balanced fertilizer application. Appropriate tillage practices together with balanced fertilizer may be a promising practice of soil management to improve soil properties and crop production. The present study was carried out in wheat-maize cropping pattern (in the year 2019-20) at agricultural research farm of Gomal University, Dera Ismail Khan, Pakistan. The experiment was set up in a split-plot layout with a randomized complete blocks design. The nitrogen levels of 0, 90, 120, 150, and 180 kg N ha-1 were assigned to subplots. Tillage and nitrogen treatments separately had a significant impact on growth and yield characteristics, but the interaction between them had minimal effect, according to the findings. The tallest heights were found in the conventional tillage plots and the high N input (N180) plots, with heights of 101 and 104 cm, respectively. The spikes per m2 were found 242 in zero tillage plots, while the highest number of spikes per plot (265) was recorded in N180. The yield contributing factor number of grain spike-1 was 48.7 in zero tillage, while the nitrogen fertilizer @ 180 kg ha-1 yielded 52, 1000-grain weight of 35g was measured in conventional tillage and 38.8g in nitrogen fertilizer plots. Deep tillage where the nitrogen @ 150 kg ha-1 was applied gave the maximum grain yields, with 3113 kg ha-1 and 3415 kg ha-1, respectively. The benefit-cost ratio of different treatments was highest in zero tillage plots, with nitrogen @ 150 kg ha-1, at 1.65. Hence, it may be concluded from the study that both tillage and nitrogen levels influenced the agronomic properties of wheat, influenced the economics of farmers, and soil fertility.

Chemodestructive fractionation of humus as an indicator of the functional state of soil organic matter

The content, composition, and properties of humus are the most important characteristics that reflect the features of modern soil formation, the genesis and evolution of soils, and their agrogenic transformation. The main criteria for assessing soil fertility are traditionally the content and reserves of organic matter in soils. At the same time, the decrease in soil fertility is associated not so much with a decrease in the total content of humus, but with the loss of its labile forms, which determine the life of the soil, its most important agronomic properties and crop yields. One of the integral indicators characterizing the state and functioning of soil organic matter (SOM) is the ratio of stable and labile forms of organic compounds obtained by chemodestructive analysis. The determination of the bichromate oxidizability of humus showed that the virgin soils of the Southern Cis-Baikal region contain an equal amount of stable and labile forms of organic compounds. Accordingly, the humus in them is a stable and balanced system in relation to external influences. Plowing led to a significant decrease in the easily and hardly hydrolysable humus fractions. In the fallow areas, the upper part of the humus horizon, in terms of the ratio of humus fractions, approaches virgin soils, and the lower part approaches the arable horizons of agricultural soils. The method of permanganate oxidizability of humus revealed a noticeable enrichment in easily oxidizable forms of virgin and, especially, fallow soils of the region. Compared to them, agricultural soils contained noticeably less labile humus, which indicates a sharp decrease in their fertility.

Determination of the shelterbelts influence on the average productivity of agrophytocenoses based on geostatistical analysis of spatial data and the NDVI

Shelterbelts effect positively on the elements of the microclimate, the water regime of soils, the agronomic properties of the soil, soil fertility in the agricultural landscape. The assessment of the influence of the density of shelterbelts on the overall productivity of arable land is poorly studied. In this study, the methodology for assessing of such impact with using GIS technologies is suggested. We propose to use the Normalized Vegetation Index (NDVI), as a standardized index showing the relative biomass of vegetation, averaged for each working area within the studied region for working plots of arable land with an area of more than 25 hectares in the Belgorod oblast. Paired correlation analysis between the density of shelterbelts and arable land productivity showed the weak relationship (R2= 0.124), however, the classification of the density of shelterbelts with the interval of 0.5 km/km2 allowed us to reveal the linear regression dependence y = 0.0059x + 0.5195 (R2 = 0.989) of arable land productivity from the density of shelterbelts. Taking into account that many abiotic factors can affect the yield, we additionally proposed to carry out typing to identify areas of the same type in terms of the relief of the earth’s surface, climatic conditions and productivity. To do this, the spatial clustering (K-means algorithm) was proposed to use. It was revealed that the productivity of agrophytocenoses increases by 10% with the increasing of the density of shelterbelts by 2 times with an average slope steepness of up to 2°. In physical terms, the yield of winter wheat will increase by 0.28 t/ha. Soil-protective crop rotations are an additional factor in increasing the value of the NDVI index on slopes more than 2°.

ECLIPTA PROSTRATA: PHARMACOLOGY, MOLECULAR GENETIC PROPERTIES, AND CULTIVATION

Eclipta prostrata (L.), (Asteraceae), commonly known as Cỏ Mực or Nhọ Nồi in Vietnamese, has been used as a traditional medicine in many countries especially in tropical and sub-tropical regions. Some important pharmacological properties of this plant are analgesic, antioxidant, anti- inflammation, HIV1 (Human immunodeficiency virus 1), anti- tumor, antibacterial, anti- termite etc. Previous reviews indicated the photochemical and pharmaceutical properties of Eclipta spp. while others were on its tissue cultivation. However, many details about the botanical, experimental or research on E. prostrata are limited. Researches on Eclipta spp. mostly focus on the pharmaceutical properties while the biodiversity and biological cultivation is still not marked. Current status of bioactivities, pharmacological profile, biotechnology application, molecular approach, and chloroplast whole genome sequence and their agronomic properties of E. prostrata are covered in this review.

Procjena agronomskih vrijednosti i stabilnost komponenti prinosa novostvorenih linija jaroga stočnog graška (Pisum sativum l.)

One of the most important tasks of breeders is to improve the properties of breeding material (varieties, lines) and to create a new genetic variability. The study goals were as follows: during two consecutive years (2019 and 2020), to evaluate the agronomic value of nine newly created spring breeding lines of fodder pea, as well as to evaluate the stability of yield components and to select the most promising genotypes for further breeding. The results of the study demonstrate that there are significant differences between the tested genotypes in the tested environments for most of the analyzed properties and that the variation of genotypes within the identified sources of experimental variation exerts the greatest influence . Based on the investigated property values, subsequent to stability evaluation the desirable genotypes L - OSMBK 1, L - OSMBK 3 – for the grain/plant yield L - OSMBK 1, L - OSMBK 8, L - OSMBK 3, L - OSMBK 9 – for the mass of 1,000 grains, and L – OSMBK 9 – for plant height were identified as the stable genotypes, with a high breeding and agronomic properties.

Exogenous application of citric acid alleviates copper-induced stress in Withania coagulans (Dunal)

The current study aimed to determine the mitigating effect of citric acid (CA) on various physiological and biochemical attributes in Withania coagulans, exposed to copper (Cu) stress. The viable seeds of Withania coagulans were planted in a controlled environment. After reaching the four-leaf stage, the plants were given simultaneous treatment with two concentrations of Cu [TCu1 and TCu2 (10mM, 15mM)] alone and/or with CA [TCa1 and TCa2 (05mM, 10mM)]. After harvesting, the physiological and biochemical characteristics of the plants were assessed. The findings demonstrated that using a higher dosage of Cu has significant toxic effects on plant growth and biomass. The agronomic attributes of the plant were significantly reduced by 24% (number of leaves), 22% (shoot length), 7% (root length), 8% (fresh weight), and 38% (dry weight) compared to the control. Higher concentration of Cu was also found toxic to photosynthetic pigments and significantly reduced by 27% (chl a), 6% (chl b), and 35% (carotenoids) compared to the control. However, the application of CA under Cu stress significantly improved the physiological attributes of Withania coagulans. The plant's agronomic traits significantly increased by 66% (number of leaves), 31% (shoot length), 87% (root length), 43% (fresh weight), and 78% (dry weight), whereas photosynthetic pigments by 25% (chl a), 58% (chl b), and 125% (carotenoids). Based on the results, it could be concluded that CA can play a role in mitigating the toxic effect of Cu in Withania coagulans

Multiyear evaluation of the agronomical and technological properties of a panel of spelt varieties under different cropping environments

Spelt is an ancient cereal that is growing in popularity but the diversity present among the different varieties available makes it difficult to choose a variety for a specific use. A total 22 European spelt varieties were therefore evaluated during four years for their agronomical (e.g. yield and disease resistance) and technological (e.g. flour rheology and gluten quality) aptitudes, in two locations in Belgium following either conventional or organic farming practices. Significant differences were observed between varieties, years and environments for most measured variables. The multivariate analysis made it possible to define groups among the varieties meeting the expectations of the sector for the different commercial applications. Sérénité appeared as a good overall candidate, with an excellent combination of agronomical and technological traits. Older varieties and landraces generally yielded poorer agronomical and technological results. Overall, modern spelt varieties showed technological properties that are well suited for biscuit making. Baking properties of spelt varieties were shown to be closely related to the nature of their high molecular weight glutenin alleles. The variety Zürcher Oberländer Rotkorn appeared as an outsider, with technological properties resembling those of bread wheat.

Liquid Leachate Produced from Vermicompost Effects on Some Agronomic Attributes and Secondary Metabolites of Sweet Basil (Ocimum basilicum L.) Exposed to Severe Water Stress Conditions

Water stress is one of the most critical threats to the growth and productivity of plants and is one of the most studied topics in agricultural sciences. In order to enhance the tolerance of plants to water stress conditions, synthetic fertilizers have been widely used in the field. However, due to their toxic effects, recent reports have focused on organic options. In this study, the effects of liquid vermicompost applications (25, 50, 75, and 100%) on the agronomic attributes, phenolic compounds, and essential oil compounds of basil plants exposed to drought stress conditions were investigated. Accordingly, water stress critically reduced the factors of plant height, plant fresh weight, root fresh weight, leaf length, and leaf diameter. On the other hand, vermicompost applications significantly affected all of the parameters considered, except the leaf length of well-watered basil plants. However, a two-way ANOVA analysis revealed that the interactions of water stress and vermicompost were significant on root length and root fresh weight. Regarding the essential oil compounds, the contents of humulene, anethol, eucalyptol, estragole, bisabolene, germacrene, and caryophyllene were quantified. Estragole was determined as a major component by 85–90%. The results revealed that the highest estragole content was determined in the 25% vermicompost + water stress, water stress, and control groups. Of the major phenolic compounds, caffeic acid decreased as a result of water stress conditions but increased with vermicompost treatments. The rosmarinic acid content increased during water stress conditions, attaining the highest content at 25% via the vermicompost and water stress interaction. In general, the 25% and 50% vermicompost applications increased the content of phenolic compounds in plants under either well-watered or stress conditions.
