Estimación de la huella hídrica agrícola del DR 011, alto río Lerma

In the search for indicators that help measure the impact of human activities on the environment and natural resources, there is one that is very useful as an indicator of demand for global water resources. Estimating the water footprint of agricultural production allowed the identification of crops that can reduce it in favor of increasing water use efficiency. Hoekstra et al. (2011) methodology was used to estimate the water footprint of agricultural products in Irrigation District 011. It was found that of 14 crops in the district, in the average total water footprint in the irrigation modules (dam3 t-1), those of peanuts, beans, and nopal report the highest levels (1.7, 1.6, and 1.8, respectively), while those of lettuce, husk tomato, and carrot crops are the lowest (0.15, 0.29, and 0.25, respectively). Of the water footprint of total agricultural production (dam3), it was observed that corn participates with 43.4%; however, it accounted for 52.8% of total production. The peanut and alfalfa crops in module 05 are economically unaffordable, with high blue water costs per tonne ($8 623.00 and $11 914.00); nevertheless, they occupy 1% of the planted area. The variation of the water footprint of crops among the irrigation modules obtained helps identify the agricultural practices that contributed to increasing yields and optimizing the application of irrigation, consequently providing greater economic benefits to producers.

Effectiveness of Organic Fertilizers in Improving Soil Fertility, Productivity and Quality of Carrots (Daucus carota) in Southern Côte d'Ivoire

In the context of agricultural resilience to climate change, a strategy of replacing chemical fertilizers with organic fertilizers has been adopted to improve the production of vegetable crops, particularly carrots. This study promotes organic carrot farming in Côte d'Ivoire by applying an organic biofertiliser based on poultry droppings and traditional medicinal plants to the soil. Different doses of this organic biofertiliser, applied to the soil by fertigation (dilution at 0.5% (T1), 5% (T2) and 10% (T3)), were tested under a crop of carrots (Daucus carota) in a completely randomized Fisher block design with 4 replications. The results show that yields varied significantly according to the different doses applied (p<0.05). High carrot yields of 27.5±1.29 t.ha-1 were obtained with treatment T2. However, plant growth indicators (plant height, number of leaves, root length and diameter) were similar for the three treatments T1, T2 and T3. According to the results obtained, treatment T2 would be suitable for achieving and maintaining an acceptable level of fertility and ensuring satisfactory yields for the carrot crop. Thus, the use of this biofertilizer should be encouraged for agro-ecological soil fertility management, and may be an alternative to synthetic fertilizers which, due to their high cost, are not accessible to growers.

EVALUASI KESESUAIAN LAHAN UNTUK TANAMAN WORTEL (Daucus carota L.) DI KECAMATAN SIRAMPOG KABUPATEN BREBES JAWA TENGAH

The characteristics and quality of soil can affect the suitability of a land for a certain type of land use. The quality of the soil itself has a close relationship with the characteristics of the land because it has a score weight that affects the suitability of the land. Land characteristics such as slope and land cover affect soil quality such as nutrient content. Erosion calculations using the USLE method show that slope and land cover affect the rate of erosion, where erosion can leach nutrients that result in decreased soil quality. This study aims to determine the suitability of land for carrot plants in Sirampog District. Sirampog District has suitable marginal to suitable temperature, suitable humidity and rainfall, suitable soil texture (loam, sandy loam, and silty loam) relatively low cation exchange capacity (CEC) with very high base saturation, acidic soil pH, medium C-organic, medium N-total, very low P2O5 and very low K2O. This study provided an evaluation of land suitability so that farmers use effective and efficient techniques in cultivating carrot plants, so that carrot crop productivity can be optimal.

Impact of Fertilizer and Mulch on Growth, Yield and Quality of Carrot in Arecanut Cropping System Under Conservation Agriculture Practices

This study aims to comprehensively assess the influence of conservation agriculture techniques, encompassing reduced tillage, cover cropping (live mulch) and nutrient levels on a range of growth parameters and the ultimate yield of crop. As per the principles of conservation agriculture i.e., soil was disturbed minimally, berseem mulch was incorporated in the experiment and carrot was raised under arecanut plantation during rabi and it was succeeded by mint crop in pre-kharif season. Experiment was laid out in Randomized block design with seven treatments of different nutrient doses and mulch replicated thrice. Field experiments were conducted across two growing seasons i.e., 2019-20 and 2020-21 during Rabi (Winter) at Balindi research farm, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur. Precise measurements and meticulous analyses were conducted on key parameters; Vegetative growth i.e., plant height and number of leaves, yield attributing parameters like root length, diameter, weight and total yield of crop. TSS and beta carotene was also estimated. These parameters unequivocally indicate that conservation agriculture practices exert a substantial influence on both the growth and yield. Among various nutrient levels, higher dose of fertilizer (T4 - 120:90:120 NPK kg ha-1) with berseem (Trifolium alexandrinum L.) as a cover crop in the interspaces showed maximum vegetative growth i.e., plant height and number of leaves plant-1 at all growth stages (30, 60 and 90 DAS) while decreasing trend was observed in yield parameters with higher levels of nutrient doses, medium level of fertilizer dose (T5 - 90:60:90 kg ha-1 + berseem (Trifolium alexandrinum) recorded highest root length, diameter, weight and projected yield of 18.5cm, 3.58 cm, 118.37 g plant-1 and 26.63 t ha-1 respectively. These findings underscore the considerable potential of conservation agriculture practices as a sustainable approach to optimize carrot crop production. This research contributes valuable scientific insights that hold significant implications for agricultural stakeholders, including farmers and practitioners, seeking to fine-tune carrot cultivation methodologies while concurrently fostering soil health and environmental sustainability.

Análise espacial da produtividade da cenoura irrigada em função das propriedades físicas do solo

ABSTRACT Understanding soil, plant attributes, and carrot crop dynamics is vital for optimizing site-specific management practices and enhancing crop yield and soil quality. This study aimed to ascertain the dependence and spatial variability between irrigated carrot yield and soil physical attributes in a clayey Oxisol. The research took place during the 2021 growing season in a commercial carrot production area in Campos Altos, MG, Brazil. One hundred sampling points were established within the irrigated area, distributed across a square expanse of 40,000 m², positioned at the centers of 20 × 20 m grids. The study revealed high yield in the irrigated carrot crop (99.74 t ha-1) with moderate variability. Soil attributes displayed a range of heterogeneity, ranging from low to extremely high, contingent on the variable assessed, as determined by the coefficient of variation. Among the variables exhibiting spatial dependence, particle density exhibited a minimum range of 40 m, which is recommended for further studies on irrigated carrot cultivation in a clayey Oxisol. Total soil water availability demonstrated a positive spatial correlation and proved to be the recommended variable for estimating the spatial variability of carrot crop yield.

Optimal Timing of Carrot Crop Monitoring and Yield Assessment Using Sentinel-2 Images: A Machine-Learning Approach

Remotely sensed images provide effective sources for monitoring crop growth and the early prediction of crop productivity. To monitor carrot crop growth and yield estimation, three 27 ha center-pivot irrigated fields were studied to develop yield prediction models using crop biophysical parameters and vegetation indices (VIs) extracted from Sentinel-2A (S2) multi-temporal satellite data. A machine learning (ML)-based image classification technique, the random forest (RF) algorithm, was used for carrot crop monitoring and yield analysis. The VIs (NDVI, RDVI, GNDVI, SIPI, and GLI), extracted from S2 satellite data for the crop ages of 30, 45, 60, 75, 90, 105, and 120 days after plantation (DAP), and the chlorophyll content, SPAD (Soil Plant Analysis Development) meter readings, were incorporated as predictors for the RF algorithm. The RMSE of the five RF scenarios studied ranged from 7.8 t ha−1 (R2 ≥ 0.82 with Scenario 5) to 26.2 t ha−1 (R2 ≤ 0.46 with Scenario 1). The optimal window for monitoring the carrot crop for yield prediction with the use of S2 images could be achieved between the 60 DAP and 75 DAP with an RMSE of 8.6 t ha−1 (i.e., 12.4%) and 11.4 t ha−1 (16.2%), respectively. The developed RF algorithm can be utilized in carrot crop yield monitoring and decision-making processes for the self-sustainability of carrot production.

First Report of the Association of the Psyllid Vector Bactericera trigonica (Hemiptera: Triozidae) with 'Candidatus Liberibacter Solanacearum' in Italy.

Psyllids, members of the family Triozidae, represent a potential threat to the cultivation of solanaceous and apiaceous crops worldwide, mainly as vectors of the phloem-restricted bacterium 'Candidatus Liberibacter solanacearum' (Lso). The Lso haplotypes C, D and E are known to affect apiaceous crops, such as carrot and celery, in several European countries. In Italy, data on the incidence and natural spread of both Lso and psyllids have not been reported so far. In this study, the presence of the vectors was investigated in a main Italian district for carrot production, the "Altopiano del Fucino" area (Central Italy). Both occasional and regular surveys were carried out on a total of five carrot fields and one potato field in 2021 and 2022. Bactericera trigonica (Hodkinson), which is known to efficiently transmit Lso to carrots, was found to be well-established in the area. High levels of population density were recorded in the summer period (more than 100 adult specimens per trap caught every two weeks) and then sharply decreased after the carrot harvest, confirming the strict association of this psyllid species with crop availability. In 2022, 27.5% of the total tested psyllid samples resulted in being positive for Lso haplotypes D and E, the latter being prevalent. This survey revealed, for the first time in Italy, the presence of B. trigonica adults associated with Lso in carrot crops. Although this study was limited to a few fields located in one area, it provided important evidence of the risks for Lso outbreaks and prompted further research to assess the spread and incidence of the disease in apiaceous cultivations in Italy.

Response of Carrot (Daucus carota L.) to Supplementary Irrigation under Rain-Fed Agriculture at Jimma and Gera, Jimma Zone, South West Ethiopia

Evaluating supplementary irrigation under rain-fed agriculture could help to determine the amount of water depth for water management and increasing productivity. Thus, this study was conducted at the Jimma and Gera to determine the effect of supplementary irrigation (SI) on carrot production. Eight treatments with three replications on a field plot of 9 m2 were used for conducting the experiment. Crop water requirement (ETc) was calculated from reference evapotranspiration (ETo) and crop coefficient (Kc) using CropWat 8.0 software. Yield and yield component data were collected from the field and analyzed using the statistical analysis system (SAS) software 9.0. The result revealed that root shoulder diameter, fresh biomass, and fresh root weight had significant (p <0.05) effects between the treatments, but there was no significant difference (p >0.05) between treatments on plant height and carrot root length at both locations. The highest and lowest plant heights were recorded at 75% SI and at a rain-fed treatment. A root shoulder diameters of 38.37 and 37.86 mm were recorded at Jimma and Gera, respectively, from the application of 75% and two SI at flowering and fruit setting treatment. The application of 75% SI gave the highest root length. A maximum fresh biomass of 3,038.6 kg/ha was obtained at 75% SI, and a minimum fresh biomass of 1,640.00 kg/ha was recorded from the rain-fed treatment at JARC. Application of 75% SI gave the maximum fresh biomass (2,388.9 kg/ha) at Gera, and a minimum fresh biomass of 1,277.8 kg/ha was recorded from rain fed. An application of 75% SI gave the highest fresh root weight of 7,430.6 kg/ha at JARC. In the study, the application of 75% SI gave the highest (6,388.9 kg/ha) fresh root weight, and the lowest was recorded at rain fed (3,883.3 kg/ha). Therefore, for optimum production, 75% SI was recommended for the production of carrots. The total net benefit from the production of carrots was in the range of 36,659–46,950 ETB per hectare at Jimma and from 24,828 up to 39,399 ETB per hectar at Gera. The maximum and minimum marginal return rate (MRR) at Jimma were 300.97%, which is at 75% SI and 43.69%, which is at 25% supplementary irrigation, respectively. At Gera, the maximum and minimum MRR were 490.95%, which were at 25% supplementary irrigation, and the minimum was 23.18%, which was at full supplementary irrigation. Therefore, to get an economic benefit, supplementing carrot crop at 75% irrigation was recommended for both Gera and JARC.

Plano experimental para a cultura da cenoura

ABSTRACT: The carrotculture stands out on the world stage due to its nutritional characteristics and economic importance, an aspect that demands the constant development of research aiming greater productivity. Thus, this study proposed an experimental plan, determining the estimates of plot size, sample size, and number of repetitions, with the purpose of increasing the precision and reliability of the results of the experiments with the carrot crop. Six uniformity trials were conducted, using three cultivars in two growing seasons (Season: 2019 and 2021).Each plant was considered a basic experimental unit and in each BEU, the variables shoot height, root length, shoot fresh mass, root fresh mass, and root diameter were measured. The size of the plot, sample, and the number of repetitions was estimated by the method of maximum curvature of the coefficient of variation. The results recommend that for experiments with the carrot crop, plots with twelve plants should be used. For a sampling of carrot plants in the plot, samples of eleven plants must be used in the direction of the row, considering a semi-amplitude of the confidence interval (D%) equal to 20% of the mean, with a confidence level of 95%. For a minimum significant difference in the Tukey test expressed as a percentage of the 50% mean, plots of twelve plants per crop row, with eight replicates, are recommended.

The impact of “continuous” deficit irrigation on carrot crop development in the Saïs plain, Morocco

In the Maghreb, as in many arid and semi-arid zones, water resources are vulnerable to climatic variations, for which reason various scientific studies are being conducted in an attempt to face these changes while maintaining the yield potential of crops. The aim of the following paper is to evaluate the impact of continuous deficit irrigation (CDI) on the carrot (Daucus Carota L.) crop. A complete randomized block design (CRBD) involving five treatments and four repetitions was adopted for this experimental design. The studied treatments are: T1(125% ETc), T2(100% ETc), T3(85% ETc), T4 (75% ETc) and T5 (66% ETc). Vegetative, biochemical, and yield parameters were measured to identify carrot response and provide optimal water management for deficit irrigation on carrot. Irrigation at 125% ETc achieved the highest yield (59 tons/ha). However, in terms of yield, treatment (T1) was not significantly different from (T2) nor (T3). Meanwhile, the 66% ETc water deficit treatment (T5) showed remarkable decreases in yield. This means that even when providing more water it does not increase the yield meaning that the plant does not use the given water but instead, it is lost and on the other hand a 15% water deficit did not significantly impact the yield.

Detection of Xanthomonas hortorum pv. carotae in Jeju Island Soils after Carrot Harvest

Bacterial leaf blight in carrot is one of the most important diseases in the worldwide. In the past decade, its introduction into Korea is causing great concern due to the potential damage to carrot crops domestically. This bacterial disease is caused by <i>Xanthomonas hortorum</i> pv. <i>carotae</i> (<i>Xhc</i>). This study aimed to isolate and identify bacterial strains from the soil of carrot farms in Jeju Island. The bacterial isolates showing characteristics similar with those of <i>Xhc</i> were selected when cultured on artificial media. Through DNA sequencing and analysis based on NCBI data, some of the selected bacterial strains were identified as <i>Xhc</i>. Furthermore, the bacterial strains caused the typical symptom of bacterial leaf blight after inoculation on carrot leaves. The results of this study showed the potential establishment of <i>Xhc</i> in the soil of Jeju Island and it may be valuable data for establish a strategy preventing the domestic spread of carrot bacterial leaf blight in the future.

Impact of isolated and unattractive crops on honeybee foraging: A case study using radio frequency identification and hybrid carrot seed crops

Abstract Hybrid vegetable varieties have become essential for global agricultural production, offering key advantages for yield, quality and disease resistance. The production of hybrid seeds is however limited by pollination challenges, with these systems commonly associated with unattractive and low‐quality floral resources, isolated growing environments and frequent insecticide applications. Here, we utilise commercial carrot seed crops to investigate the impact of hybrid pollination on the behaviour of the honey bee (Apis mellifera). Six full‐strength bee colonies were equipped with solar powered radio frequency identification systems and over 900 tagged bees per season. These colonies were deployed to commercial hybrid seed crops over two consecutive seasons. The colonies were allocated to either an on‐crop or off‐crop group. Individual bees were autonomously monitored for the pollination period to assess key parameters such as survival, age at foraging and the number and duration of orientation and foraging trips. Hybrid carrots were found to have a significant impact on bee foraging behaviour. Bees situated on the carrot crop undertook less frequent yet longer foraging trips, resulting in less total time outside of the colony compared to off‐crop bees. However, bees placed in carrot fields survived to an older age, orientated successfully, became foragers later and collected more pollen by weight, despite only 2% originating from carrot. We hope that the improved behavioural understanding can be utilised to enhance both pollinator health and hybrid seed production globally.

Carrot productivity and its physiological response to irrigation methods and regimes in arid regions

Abstract The aim of this study is to optimize water irrigation management for improving carrot productivity and water-saving in arid regions of southern Tunisia. Field studies were conducted over two seasons (2017–2019) to evaluate the effects of drip irrigation (DI) and surface irrigation (SI) methods coupled with three irrigation regimes on agronomic parameters of carrot crops. Irrigation regimes consisted of water replacements of cumulated crop evapotranspiration (ETc) at levels of 100% (I100), 70% (I70), and 40% (I40) when the readily available water in I100 treatment was depleted. Results showed a reduction in carrot yield by 13–22% and 22–32% with I70 and I40 treatments compared to I100, respectively. Yield is affected by the irrigation method with a reduction of around 6–7% under the surface method for both years. The water productivity (WP) was found to significantly vary among regimes and methods, where the highest values were observed for the I40 regimes and drip method. Drip and I100 irrigation techniques seem to optimize carrot production. Under situations of water shortage, adopting deficit irrigation treatment (DI70) could be an alternative for managing carrot irrigation and improving water productivity.

Weeds as Bioindicators of Ecological Conditions in Organic Carrot and Onion Crop

Summary The obtained results indicate the possibility of weed control in organic intercropping production systems of carrots and onions with the application of corn gluten, together with the ecological assessment of habitat based on bioindicator values of weed species. A total of 29 weed taxons are present in the intercoped and pure crops of carrots and onions, grown without (CO) and with the application of corn gluten (CO-G). Although floristically uniformed, 24 taxons (CO) and 23 taxons (CO-G), the total weediness on the CO-G variants was 24% higher. The highest value of fresh weed biomass was recorded on the treatment of pure onion crop with gluten application (2844.85 g/m2), while the lowest value was recorded on the treatment of intercropped carrot and onion (1004.99 g/m2). Ecological assessment of habitat, based on indicator values and abundance of weed species, indicates favorable climatic conditions with favorable temperature (Tx̄ - 4) and light (Lx̄ - 4) regime, which refers to temperate continental climate conditions (Kx̄ - 2,7). Soil indicators indicate slightly drier conditions (Fx̄ – 2,6), slightly acidic to neutral pH (Rx̄ – 3,3), rich in nutrients (Nx̄ – 4), with moderate humus content (Hx̄ – 3), moderate aeration (Dx̄ – 2,8) and locally salted (s) with the participation of salinity indicators in the amount of 54% (CO) and 40% (CO-G). The presence of heavy metals tolerance (m) indicators in the amount of 46% (CO-G) and 41% (CO) should not be neglected, which imposes the need for additional analysis of soil for heavy metal content. Based on the analysis of obtained indicator values, it can be concluded that these ecological conditions correspond to the development of carrots and onions and that the lowest values of fresh weed biomass were recorded on the treatment of intercropping of carrots and onions, without application of corn gluten.

The golden native drone fly (Eristalinus punctulatus) is an effective hybrid carrot pollinator that lives within Australian crop agroecosystems

Abstract Native insect flower visitors can be important contributors to crop pollination, yet little is known of their pollination abilities and the resources (habitat) they need to be supported within crop agroecosystems. Here, we compared the abundance and pollination abilities of the golden drone fly (Eristalinus punctulatus) to the European honey bee (Apis mellifera) in hybrid carrot crop fields known to produce variable seed yields in regional New South Wales, Australia. We further observed the egg‐laying behaviours of female golden drone flies at a commercial berry orchard to provide insight into the habitat needs of this species. In hybrid carrot crop fields, golden drone flies were far less abundant flower visitors than European honey bees; however, these flies deposited more carrot pollen grains on average (8.21 ± 3.04 SE) onto carrot flowers than European honey bees (3.45 ± 1.06 SE). Both insects also deposited pollen onto a similar number of carrot flowers (pollinated) per visit (about 2 out of 18). Golden drone flies were observed laying eggs within masses of discarded red raspberry plant roots and soil (root balls) at a commercial berry orchard. The natural habitat utilised by these flies, as well as their egg‐laying behaviours, were described for the first time. Our results indicate that golden drone flies are effective pollinators of hybrid carrot crop plants. The habitat that these flies utilised to lay eggs (discarded plants and water) is cheap and commonly found in crop agroecosystems. Therefore, we recommend placing this low‐cost habitat within, or nearby, crop fields as a potential management practice to support the lifecycle needs of golden drone flies and other non‐bee pollinators.

Macronutrient absorption curves of carrot in the high tropics

Carrot cultivation in Colombia reached 9,000 hectares in 2020. The production chain of this crop faces various problems, among which marketing and nutrition stand out, the latter a decisive factor for performance. Some studies claim that with the use of hybrids in combination with irrigation and balanced fertilization, yields greater than 70 t ha-1 can be obtained. The commercial competitiveness of crops is related to the timely, adequate and efficient application of nutrients; element absorption curves are tools that offer effective information on how much the crop assimilates during its phenological cycle, allowing us to know the minimum required amount of elements for the specific area. A carrot crop was established to determine the foliar absorption curves of macronutrients (N, P, K, Mg and Ca). The yield obtained was 39.6 t ha-1, with 552,500 plants/ha. K was the element with the highest absorption 147 days after sowing with 29.36 kg ha-1 for the leaves and 27.74 kg ha-1 in the root and a total of 57.1 kg ha-1. The order of the other elements was N, Ca, P and Mg. This information is useful for managing carrot nutrition in order to make fertilizer management efficient and improve yield.

Estimating Carrot Gross Primary Production Using UAV-Based Multispectral Imagery

Gross primary productivity (GPP) is an essential parameter to assess the efficiency of terrestrial ecosystems on carbon transfer. Although GPP is regularly measured with eddy covariance (EC) systems, these are restricted to the tower footprint area, and remote sensing (RS) products have estimated GPP using multispectral vegetation indexes (VIs) from farms to whole ecosystems. Indeed, nowadays, unmanned aerial vehicle (UAV)-based RS technology is becoming more accessible. Accordingly, we propose the estimation of GPP using VIs at high spatial resolutions using UAVs and multi-spectral cameras. A small typical farm in Colombia was cultivated with carrot as our base crop. An EC system was installed to estimate GPP and was used as a reference. A total of 24 VIs from UAV-based RS products were selected and compared with the GPP of the EC system. A cross-validation process was performed, and seven VIs obtained a high R2 score (0.76–0.78). The accumulated GPP, estimated with the best index (NIRv) was 520.3 g C m−2, while the GPP-EC estimate was 580.4 g C m−2 (10.3% error). This work showed that it is possible to estimate the GPP of carrot crops using UAV-based RS, VIs, and linear regression models, which can be used in further research on GPP using UAVs.

ВЗАИМОДЕЙСТВИЕ ФАКТОРОВ ПРИ ОЦЕНКЕ СОРТОПОПУЛЯЦИЙ МОРКОВИ СТОЛОВОЙ НА УСТОЙЧИВОСТЬ К FUSARIUM И ALTERNARIA

At present more than 10,000 species of fungi associated with plants have been identified. A convincing proof of this is the widespread spread of fungal diseases on table carrots at all stages of plant development. Seedlings of Daucus carota L. are affected by pathogens of the genus Fusarium, causing a disease called «black leg», which leads to the death of infected seedlings. Adult plants are damaged by brown leaf spotting (pathogen Alternaria dauci (Kuhn), Grovers & Skolko), which contributes to premature death of the tops, which makes it difficult to use mechanization tools when harvesting root crops. With a high degree of plant damage in the root crops of table carrots, the content of carotene decreases by 24 % and sugars by 31 %. The degree of alternariasis spread by the end of the growing season reaches 90–100 %. These diseases of carrots are the most common and harmful in the Russian Federation and in the world. The creation of new highly productive and pathogen-resistant varieties and hybrids of carrots is complicated by the fact that the signs of resistance to fungi of the genera Alternaria and Fusarium in table carrots are controlled polygenically. Based on the above, the purpose of the research was: To identify the interaction of factors during field and laboratory experiments on varietal populations of table carrots to pathogens of the genera Fusarium and Alternaria. As a result of the work carried out, a high correlation coefficient (more than 0.70) was revealed between the assessment of mycosis resistance in field and laboratory experiments: spraying with a suspension of A. dauci leaf plate spores; infection of A. radicina and F.oxysporum seedlings; infection of disks with A. radicina and F. oxysporum mycelial blocks; evaluation of A. dauci and F. oxysporum culture fluid filtrate; assessment of resistance on artificial infectious backgrounds of A. radicina, A. dauci and F. oxysporum. A medium-susceptible group of varieties of table carrots has been identified, these are Vitamin 6, Losinoostrovskaya 13, Leander, Nuance, Queen of Autumn, Topaz F1, Star F1, Color F1, Irkut F1.
