Eggshells Improve Soil pH and P Availability in Sandy Loam and Sandy Clay Loamy Soil

The current effective method of mitigating soil acidity is the application of lime. However, the costs associated with acquiring lime make it challenging for small-scale farmers in South Africa. Therefore, the aim of this study was to evaluate the liming potential of ground eggshells relative to aglime and its effect on P availability in two acidic soils differing in textural classes, and its subsequent effect on the growth of Swiss chard (Beta vulgaris L.). Two soils used in the study were sandy clay loam, which had an initial pH of 4.52, and sandy loam with an initial pH of 5.23. Both lime sources were applied at a rate of 0, 1, 2.5, and 5 t/ha through incubation for 120 days. Our results indicated that applying eggshells and aglime significantly increased soil pH within 7 days (p < 0.05) compared to the 0-rate application across all application rates in both soil types. There were no differences (p > 0.05) in pH between the two applied lime sources. Plant-available P was not significantly different between the applied lime sources at all application rates and the 0-rate application; however, the two lime sources increased plant-available phosphorus above 25 ppm, which is the minimum health level of plant-available phosphorus. The results of plant yield showed no differences (p > 0.05) between the plant dry weights. However, Swiss chard growing at the 0-rate application in the sandy clay loam showed poor and stunted growth while Swiss chard growing at the 0-rate application in the sandy loam did not exhibit poor and stunted growth. According to the study’s results, eggshells have a similar liming effect as aglime and their dissolution rate is similar; therefore, eggshells can be used as a substitute of aglime to increase soil pH. Using eggshells as a substitute for aglime could offer substantial benefits to small-scale farmers by reducing input costs and providing a locally sourced, sustainable alternative. This approach can also enhance economic sustainability in rural communities by promoting the recycling of agricultural by-products and making essential soil amendments more affordable and accessible.

Genetic architecture of Cercospora leaf spot response in table beet with implications for other Beta vulgaris crop types

AbstractTable beet (Beta vulgaris subsp. vulgaris) production is threatened by the fungal disease Cercospora leaf spot (CLS). Infections are common across table beet's closest relatives, including Swiss chard, sugar beet, and fodder beet (all B. v. subsp. vulgaris). This study was conducted to characterize the genetic architecture underlying CLS response in table beet. A secondary objective was to test whether CLS‐associated loci in table beet perform similarly across B. vulgaris crops. A diversity panel comprised of 168 table beet accessions and with an additional 70 accessions from all close relatives of table beet was screened for CLS response in replicated and inoculated field trials. Results from a genome‐wide association study of additive effects revealed seven quantitative trait loci mapped to chromosomes 1, 3, 7, and 9 to explain 30% of the phenotypic variation for CLS response in table beet. When the performance of these loci was compared between a table beet background and a background of Swiss chard, sugar beet, and fodder beet, two loci exhibited significantly different responses. Among the B. vulgaris crops, these loci may be unique to table beet germplasm and could be useful for the improvement of CLS resistance in other crop types. For the improvement of CLS resistance in table beet, this study identified the cultivar Winter Keeper as a potentially valuable source of resistance. The architecture of CLS response points to recurrent selection and backcross methods as effective strategies for the improvement of CLS resistance in table beet.

Identification and functional analysis of the Dof transcription factor genes in sugar beet.

In this study, members of the BvDof transcription factor family were identified in the beet genome data (Beta vulgaris L.) Through systematic analysis, 22 BvDof family genes were found in the beet genome, and they were divided into nine groups by phylogenetic analysis. Fifteen members of the BvERF family were involved in the transition to rapid root tuber growth. There was a tandem replication during the generation of the Dof gene family in sugar beet. Bv1_zfms, Bv_ofna, Bv5_racn, and Bv6_augo may be involved in the regulation of secondary cambium development in the beet root tuber. Bv9_nood, Bv1_zfms, and Bv6_cdca may be related to the growth rate of root tubers. The results provide a reference for further elucidating the molecular mechanism of the BvDof transcription factor, which regulates the development of beet root tubers.

Leuconostoc suionicum and Leuconostoc pseudomesenteroides are important lactic acid bacteria identified in rotted tissues of roots in the field and stored sugar beets. Here, we announce the genomes of L. suionicum and L. pseudomesenteroides, isolated from post-harvest sugar beet roots from Idaho and Minnesota.

The Complexity of the Influence of Growth Substances, Heavy Metals, and Their Combination on the Volume Dynamics of Vacuoles Isolated from Red Beet (Beta vulgaris L.) Taproot Cells

The plant vacuole is a very dynamic organelle that can occupy more than 90% of the cell volume and is essential to plant cell growth and development, the processes in which auxin (indole-3-acetic acid, IAA) is a central player. It was found that when IAA or FC (fusicoccin) was present in the control medium of vacuoles isolated from red beet taproots at a final concentration of 1 µM, it increased their volume to a level that was 26% or 36% higher than that observed in the control medium without growth regulators, respectively. In the presence of IAA and FC, the time after which most vacuoles ruptured was about 10 min longer for IAA than for FC. However, when cadmium (Cd) or lead (Pb) was present in the control medium at a final concentration of 100 µM, it increased the volume of the vacuoles by about 26% or 80% compared to the control, respectively. The time after which the vacuoles ruptured was similar for both metals. The combined effect of IAA and Pb on the volume of the vacuoles was comparable with that observed in the presence of Pb only, while for FC combined with Pb, it was additive. The use of IAA or FC together with Cd caused in both cases a decrease in the vacuole volumes by about 50%. The data presented in this study are discussed, taking into account the structure and function of the vacuolar membrane (tonoplast) and their changes in the presence of growth substances, heavy metals, and their combination.

Effect of zeolite application on soil enzyme activity of potted sandy soil cultivated with Swiss chard and cabbage

A zeolite pot experiment was conducted at the Agricultural Research Council Infruitec-Nietvoorbij in Stellenbosch, South Africa, under greenhouse conditions. The experiment aimed to investigate the impact of zeolite application on soil enzyme activities in sandy soils cultivated with Swiss chard (Beta vulgaris Var. cicla) and cabbage (Brassica oleracea Var. capitata L.) over two years (2018-2019). Different zeolite-to-soil ratios (0:1, 1:9, 2:8, and 3:7 w/w) were used, with each pot containing 12 kg of soil. The experiment involved 72 pots for each vegetable, arranged in a randomized complete block design (RCBD). Soil enzyme activities, including acid phosphatase, β-glucosidase, and urease, as well as soil chemical properties (pH, total plant-available nitrogen, organic carbon, and phosphorus), were analyzed. Key findings indicate that the effect of zeolite application on enzyme activities varied between the vegetable species. Zeolite application significantly increased (P

The role of zeolite and mineral fertilizers in enhancing Table Beet (Beta vulgaris L.) productivity in dark chestnut soils of Southeast Kazakhstan

This study evaluated the effectiveness of zeolite, both alone and in combination with mineral fertilizers, in improving the yield and quality of table beets (Beta vulgaris L.) grown in dark chestnut soils of southeast Kazakhstan. The research was conducted at the Kazakh Research Institute of Horticulture during the 2022-2023 growing seasons using a randomized complete block design with six treatments: control (no fertilizers), zeolite 2 t/ha, N45P45K45 (single dose of mineral fertilizers), N90P90K90 (double dose of mineral fertilizers), zeolite 2 t/ha + N45P45K45, and zeolite 2 t/ha + N90P90K90, replicated three times. The application of zeolite significantly improved soil physical properties, such as water permeability and soil density, enhancing root development and water retention. Nutrient availability, particularly nitrate nitrogen and mobile phosphorus, increased significantly in zeolite-treated plots. The combination of zeolite and mineral fertilizers resulted in the highest improvements, with nitrate nitrogen content reaching 40.5 mg/kg and mobile phosphorus 89.2 mg/kg. Moreover, zeolite reduced heavy metal concentrations, particularly cadmium, by 50% compared to the control. Table beet yield significantly increased with zeolite application, with the highest yield of 62.7 t/ha achieved with 2 t/ha zeolite combined with double dose N90P90K90 fertilizers, compared to 42.8 t/ha in the control. Marketable yield also improved, indicating better crop quality. Nutrient composition of the beets improved, with increased dry matter content (21.9%) and reduced nitrate content (240 mg/kg) in zeolite-treated variants. In conclusion, zeolite, especially when combined with mineral fertilizers, effectively enhances soil health, nutrient availability, and table beet yield and quality.

Optical Study on Co-Sensitization of Betanin Dye with Cadmium Sulfide to Fabricate Dye Sensitized Solar Cell

Natural dyes are low-cost, eco-friendly, readily available and have optical characteristics which render them useful in energy research. The titanium tetra isopropoxide precursor can be employed using sol-gel synthesis to get titanium dioxide nanoparticles (TiO2 NPs). The FESEM analysis confirmed the deposition of TiO2 NPs on Indium Tin Oxide (ITO) substrate, which is necessary for the photo-conversion mechanism to produce electricity. One of the natural dyes that is extracted from red beets is known as betanin dye (Bd). Due to their aligned energy levels, Bd and cadmium sulfide (CdS) are used together to provide effective optical characteristics, making them suitable as dye sensitizers. The presence of Cd-S, C-N and hydroxyl groups assigned to 500, 1633, and 3300 cm-1 respectively, was demonstrated by the FTIR analysis. The energy gap of 2.16, 2.13 and 2.2 eV for Bd, CdS and Bd-CdS composite was estimated using Tauc's plot and UV-visible spectra demonstrated maximum absorbance at 485, 510 and 528 nm, respectively. The Bd absorbs broad light in visible region due to the addition of CdS. The major charge-transport phenomenon in dye-sensitized solar cells (DSSC) involves an increase in photo-current density, due to its luminous nature. However, the recombination of charge carriers prevents the overall performance of the DSSCs. The power conversion efficiency of the DSSC constructed from Bd dye and Bd-CdS composite was 0.234% and 0.367%, respectively. This optical investigation suggests co-sensitization as a sure-fire method to improve the efficiency of DSSCs extracted from natural dyes, making them reliable for future indoor applications.

Exploring Sampling Strategies and Genetic Diversity Analysis of Red Beet Germplasm Resources Using SSR Markers

By using 14 SSR primer pairs, we here analyzed and compared the amplification results of 534 DNA samples from six red sugar beet germplasm resources under three treatments. These data were used to explore the sampling strategy for the aforementioned resources. Based on the sampling strategy results, 21 SSR primer pairs were used to evaluate the genetic diversity of 47 red sugar beet germplasm resources. The six population genetic parameters used for exploring the sampling strategy unveiled that individual plants within the population had a relatively large genetic distance. The genetic parameters Ne, I, and Nei’s of the randomly mixed sampling samples increased rapidly between 10 and 30 plants before decreasing. Therefore, when SSR technology was used to analyze the genetic diversity of the red sugar beet germplasm resources, the optimal sampling gradient for each population was the adoption of a random single-plant mixed sampling sample of no less than 10 plants and no more than 30 plants. The 21 SSR primer pairs were used to detect genetic diversity in 30 random mixed samples of 47 resources. The average polymorphic information content (PIC) was 0.5738, the average number of observed alleles (Na) was 4.1905, the average number of effective alleles (Ne) was 2.8962, the average Shannon’s information index (I) was 1.1299, the average expected heterozygosity (Nei’s) was 0.6127, and the average expected heterozygosity (He) was 0.6127. The genetic distance of the 47 germplasm resources ranged from 0.0225 to 0.551 (average: 0.316). According to the population structure analysis, the most suitable K value was six, which indicated the presence of six populations. Based on the clustering analysis results, the 47 germplasm resources were segregated into six groups, with obvious clustering and some germplasm resources noted for having groups with close genetic relationships. We here established a more accurate and scientific sampling strategy for analyzing the genetic diversity of red sugar beet germplasm resources by using SSR molecular markers. The findings provide a reference for collecting and preserving red sugar beet germplasms and protecting their genetic diversity.

Bioconversion of sugar beet molasses into functional exopolysaccharides by beet juice-derived lactic acid bacteria

Sugar beet molasses, a sugar-rich byproduct of sugar beet industry, have great potential as a biorefinery feedstock for the production of value-added bio-products by microbial fermentation. The production of functional exopolysaccharides (EPS) by lactic acid bacteria (LAB) represents a promising strategy for valorizing sugar processing waste. This study screened and identified high-efficiency EPS-producing LAB isolates from beet juice. Among the 32 isolates, six LAB strains including Limosilactobacillus fermentum YL7, Lactiplantibacillus plantarum YL4, TC10, and CJ10, Leuconostoc mesenteroides TCT3 and TCT4, exhibited efficient bio-conversion of beet molasses to LAB-EPS, with yields varying from 13.96 to 22.26 g/L. Antioxidant activity analysis revealed that EPS from these strains displayed significant scavenging activities against ABTS+, DPPH, and -OH radicals. Notably, EPS produced by L. plantarum TC10 and L. fermentum YL7 exhibited superior ABTS + scavenging capacity, with rates up to 99.48% and 95.89% at 4 mg/mL, respectively. Additionally, EPS from strains YL4, YL7, TCT3 and TCT4 showed significant antibiofilm activity against S. aureus and E. coli, with EPS-YL7 inhibiting S. aureus biofilm formation by up to 90.49% at 8.0 mg/mL. Furthermore, EPS from strains TCT4 demonstrated great tolerance to digestive fluid compared to EPS from other strains, with a retention rate of 72% at the end of intestinal digestion. These findings suggest that EPS-producing LAB strains from beet juice can efficiently convert beet molasses into valuable EPS utilized as functional food ingredients.

Betanin-encapsulated starch nanoparticles: synthesis and cytotoxic effect on colon cancer.

Colorectal cancer (CRC) is a common and life-threatening neoplastic disease that continues to pose a formidable challenge to global health. The present work was performed to evaluate the anticancer properties of betanin and betanin (BT) loaded starch nanoparticles (S-BT). The BT and S-BT were characterized by DLS, SEM, UV spectroscopy, XPS and FTIR. The cytotoxic effect was assessed by MTT and LDH assay. The apoptotic potential of BT and S-BT was assessed by DCFDA, Rh123, AO/EB and DAPI staining methods. Cell cycle arrest was depicted using flow cytometry. The antimetastatic potential of BT and S-BT was evaluated by wound healing assay. The S-BT showed a spherical morphology with a size of 175nm. The betanin contained SNPs were found to have strong encapsulation efficiency and favorable release profiles. Both BT and S-BT exhibited cytotoxicity in SW480 cells but S-BT displayed increased cytotoxicity when compared to BT alone. Loss of mitochondrial membrane potential, nuclear fragmentation, chromatin condensation and generation of ROS, all indicative of apoptotic mode of cell death, were revealed by fluorescence imaging. The cells were arrested in the G2M phase. Moreover, both BT and S-BT were able to inhibit the migratory potential of SW480 cells. Overall, our results indicated that both BT and S-BT were able to induce anticancer effects; and, S-BT was found to have increased therapeutic efficacy when compared to BT alone.

Combinatorial iterative method for metabolic engineering of Yarrowia lipolytica: Application for betanin biosynthesis

Combinatorial library-based metabolic engineering approaches allow lower cost and faster strain development. We developed a genetic toolbox EXPRESSYALI for combinatorial engineering of the oleaginous yeast Yarrowia lipolytica. The toolbox enables consecutive rounds of engineering, where up to three combinatorially assembled gene expression cassettes can be integrated into each yeast clone per round. The cassettes are integrated into distinct intergenic sites or an open reading frame of a target gene if a simultaneous gene knockout is desired. We demonstrate the application of the toolbox by optimizing the Y. lipolytica to produce the red beet color betanin via six consecutive rounds of genome editing and screening. The library size varied between 24 and 360. Library screening was facilitated by automated color-based colony picking. In the first round, betanin pathway genes were integrated, resulting in betanin titer of around 20 mg/L. Through the following five consecutive rounds, additional biosynthetic genes were integrated, and the precursor supply was optimized, resulting in a titer of 70 mg/L. Three beta-glucosidases were deleted to prevent betanin deglycosylation, which led to a betanin titer of 130 mg/L in a small scale and a titer of 1.4 g/L in fed-batch bioreactors. The EXPRESSYALI toolbox can facilitate metabolic engineering efforts in Y. lipolytica (available via AddGene Cat. Nr. 212682–212704, Addgene kit ID # 1000000245).

Development of bio-active cotton fabric coated with betalain extract as encapsulating agent for active packaging textiles

The development of bio-active cotton fabric based on natural polymers and pigments has been a significant material for biodegradable textile packaging in recent years. Betalain extracted (BE) from Red beet root (RBR) is a rich source of natural pigments and has potential health benefits as an antioxidant and in biological activities which used as food, beverage, and drug colorant. However, BE pigments are photochromically unstable and have interest applications, thereby motivating the use of microencapsulation technology to maintain their stability and increase their shelf lifetime. Thus, in the present work Incorporating BE into gelatinized corn starch (GS) and Arabic gum (AG) for manufacturing stabilized BE microcapsules with tunable antioxidant and biological properties by freeze-drying method. The produced encapsulating agent (EA) powders were analyzed by scanning electron microscope (SEM) for particle morphology and FTIR of selected EA was carried out. Monitoring of coloring strength values (K/S) and Color parameters before and after storage as well as storage stability of these microcapsules at different pH’s was also studied. The current study was performed to design multifunctional cotton fabric, for this purpose the cotton fabric was treated with keratin to improve its affinity toward 100 % BE, with and without (BE) EA were determined using a pad dry process. The chemical properties, physical properties, mechanical properties, thermal stability, and functional properties of the coated fabrics with and without (BE) as well as color parameters were determined. The results showed that the fabric coated with 100 % BE and 30 % BE incorporating or encapsulating with 60 % GS and 10 % AG exhibited good mechanical properties, excellent thermal stability, and significant antioxidant and antimicrobial activity compared to the uncoated fabric. The antioxidant release of BTE from the fabric coated with 60/10/30 EA was controlled by diffusion. According to the results, the developed multifunctional coated fabrics with BE encapsulating agent can be considered as a good potential material for active packaging textiles for various applications.

Technology of preparation and determination of the properties of kvas from table beet for use in bakery

In connection with the deterioration of the health of the population of Ukraine, the primary task should be to enrich the usual diet with products of functional purpose and to add natural biologically active additives that contribute to the removal of radionuclides, toxins, normalization of the body's systems and increased immunity. This work is devoted to the study of the process of beet processing and its further use in the bakery and confectionery industries. The refractometric method was used to determine the content of soluble solids. The content of trace elements was determined using the atomic adsorption method. When preparing kvass from table beets, additional raw materials were added: sprouted flax seeds, whey, yeast, viburnum powder, rye bread crackers. It was established that the variety of the Dutch selection Roket differs from the varieties Bordeaux 237 and Cylindra in terms of dry matter, organic acids, dyes and sugars. It is important to note that when improving kvass preparation technology, optimal fermentation conditions and dosing of additives are taken into account in order to maximize the shelf life of the product without losing its quality. In view of the increase in the number of genetic and complicated diseases, it is worth noting the introduction of specialized dietary programs, which are gaining more and more relevance. Such programs have been found to ensure food security and meet all essential nutrient needs. Considered the problem of the need for constant improvement of recipes of food products, study of new gluten-free alternatives and provision of access to high-quality gluten-free products. Studies have proven that the use of natural raw materials in the production of beet kvass is an effective means of improving its quality characteristics. Therefore, a promising direction in the production of flour products is the improvement of the recipe of the existing assortment due to the use of natural plant components of increased biological value. Kvass from table beet can be a source of natural biologically active substances (BAR). Table beets have a rich chemical composition. The nutritional value of beets is additionally balanced by the content of sugars and acids (citric and oxalic), the content of organic substances, minerals and vitamins. The production of bakery products using kvass from table beet as a natural food additive is relevant today.

Susceptibility of Table Beet Cultivars to Foliar Diseases in New York

A collection of foliar diseases affects table beet production in New York. The predominant diseases are bacterial leaf spot (BLS) caused by the bacterium Pseudomonas syringae pv. aptata; Cercospora leaf spot (CLS) caused by the fungus Cercospora beticola; and Phoma leaf spot (PLS) caused by the fungus Phoma betae (syn. Neocamarosporium betae). Little is known of the potential to use host resistance in an integrated program for table beet disease management. Field trials evaluated the susceptibility of selected table beet cultivars (Bohan, Bresko, Manolo, Pablo, Red Cloud, Ruby Queen, Subeto, and Bazzu/Irazu) to BLS, CLS, and PLS. Bohan was one of the least susceptible to BLS but was moderately and highly susceptible to CLS and PLS, respectively. Bresko was moderately susceptible to BLS and CLS and was among the least susceptible to PLS. Manolo was one of the least susceptible to BLS and PLS but was highly susceptible to CLS. Pablo and Red Cloud were moderately or highly susceptible to all diseases. Subeto was moderately susceptible to BLS and CLS but was the least susceptible to PLS. Ruby Queen, the processing standard, was the least susceptible to BLS and PLS and was moderately susceptible to CLS. Bazzu and Irazu (2021 and 2022, respectively) were among the least susceptible to all diseases and were the only cultivars tested with reduced CLS susceptibility. These findings emphasize the need to evaluate table beet cultivar susceptibility to the spectrum of foliar diseases. This information may underpin cultivar selection based on the varying importance of diseases in specific production situations.

Energy-saving technology for harvesting root crops and potatoes

The purpose of the work is to empirically determine the temperature of the exhaust gases when changing the load on the power plant of a beet harvester with a separating system that provides better harvesting quality in conditions of high soil moisture. Have been developed: classification of methods for increasing the separating ability of slot-hole devices for cleaning root crops; laboratory installation for determining the quality indicators of a separation system with thermal energy for exhaust gas purification with a star-shaped cleaning device; a method for assessing the process of heat transfer from the exhaust gases of the power plant of the self-propelled harvester for harvesting sugar beets Holmer Terra Dos T3 to the separating system, which involves determining the temperature using thermocouples installed at various points in the gas exhaust system of the internal combustion engine. An experimental study of the temperature of the exhaust gases of the power plant of a harvesting machine was carried out using thermocouples at maximum rotation speed with a change in the thermal load index of the external environment from 5 to 30°C. The heat of the exhaust gases from the Mercedes-Benz power plant of the Holmer Terra Dos T3 self-propelled harvester, aimed at blowing the working surface of the separating device at the outlet of the first and fourth, as well as the second and third cylinders, has minor discrepancies exceeding the error limits (65 ± 5.8; 63.2 ± 1.5 and 74.9 ± 2.4; 75.2 ± 2.0°C, respectively), which leads to a uniform distribution of heat flow on the device for cleaning sugar beet roots.
