Yield and Quality of Carrot Cultivars with Eight Nitrogen Rates and Best Management Practices

Carrot (Daucus carota) production has increased in North Florida and South Georgia since 2015. Deep sandy soils, moderate winter climate, availability of irrigation water, and proximity to eastern markets are favorable for carrot production in the region. Nitrogen (N) is required for successful carrot production, and the current recommended N application rate in Florida is 196 kg·ha−1. The objective of this study was to verify the recommended N rate for the sandy soils of North Florida using current industry standard cultivars and practices. Carrot cultivars for the whole carrot fresh market, Choctaw and Maverick, and cultivars for the cut-and-peel market, Triton and Uppercut 25, were direct seeded on 102-cm-wide pressed bed tops on 29 Oct. 2016 and 2 Nov. 2017 in Live Oak, FL. Eight N application rates (56, 112, 168, 224, 280, 336, 392, and 448 kg·ha−1) were tested, and all N applications were placed on the bed top. N rates were split and timed to increase N use efficiency. Regression analyses were used to determine the optimal N rate for carrots in North Florida. A quadratic plateau regression for both seasons combined indicated 206 kg·ha−1 N was the optimal rate for carrots, with marketable yield of 71.3 Mg·ha−1, regardless of cultivar. All four cultivars attained acceptable yield including Uppercut 25, which exhibited significant foliage damage following freezing temperatures. This study resulted in updated information on best management practices for carrot production in Florida, especially nutrient stewardship.

Utilization of Carrot Pomace to Grow Mealworm Larvae (Tenebrio molitor)

Edible insects are a sustainable food source to help feed the growing population. Mealworms (Tenebrio molitor) can survive on a variety of food wastes and alter their composition based on the feed source. Commercial carrot production produces an abundance of carotenoid-rich carrot pomace, which may be beneficial for mealworm larvae growth. This study uses an I-optimal response surface design to assess the effect of dehydrated carrot pomace concentrations (made up with wheat bran as the control) in the substrate and wet carrot pomace as the moisture source (potato and carrot as control moisture sources) in a mealworm-larvae-growing system. Using this design, statistical models were fit to determine the relationship between the substrate and moisture and dependent variables, which include mealworm larvae mortality, days to maturity, weight, protein content, fat content, moisture content, ash content, and total carotenoid content. An optimum diet was proposed, in which the best diet for improving commercial mealworm growth was found to contain 36% dehydrated carrot pomace in the substrate, with wet carrot pomace as the moisture source. This research provides an application for a commercial waste stream and provides insight to help improve the growth of a sustainable protein source.

Spatial Variability of Nitrogen Uptake and Net Removal and Actual Evapotranspiration in the California Desert Carrot Production System

Nitrogen (N) and irrigation water must be effectively used in mineral soils to produce carrots with high yield and minimal environmental impact. This study attempts to identify optimal N and irrigation management practices for low desert carrot production in California by investigating consumptive water use and N uptake and removal rates in fresh market and processing carrots. Field experiments were conducted at the University of California Desert Research and Extension Center and nine farmer fields during two growing seasons. The actual evapotranspiration (ETa) was measured using the residual energy balance method with a combination of surface renewal and eddy covariance equipment. Crop canopy coverage, actual soil nitrate-N from multiple depths as well as total N percentage, dry matter, and fresh biomass in roots and tops were measured over the growing seasons. The length of the crop season had a wide range amongst the experimental sites: from a 128-day period in a processing carrot field to as long as 193 days in a fresh market carrot field. The seasonal ETa varied between 305.8 mm at a silty loam furrow irrigated processing carrot field and 486.2 mm at a sandy clay loam sprinkler irrigated fresh market field. The total N accumulated at harvest ranged between 205.4 kg ha−1 (nearly 52% in roots) and 350.5 kg ha−1 (nearly 64% in roots). While the mean value of nitrogen removed by carrot roots varied from 1.24 to 1.73 kg N/Mg carrot roots, it appears that more N was applied than was removed by carrot roots at all sites. Within the range of N application rates examined at the experimental sites, there was no significant relationship between carrot fresh root yield and N application rate, although the results suggested a positive effect of N application on carrot yield. Sufficient soil N availability over the growing season and the lack of significant yield response to N application illuminated that optimal N rates are likely less than the total amounts of N applied at most sites.

Analytical justification of the automatic control system of the technological process of post-harvesting root and onion

It is marked that the applied technical means of automation of machine-technological complexes for the production of agricultural products differ significantly from those conventionally taken as ideal, in this regard, it is necessary to develop requirements for the accuracy and reliability of the measuring information of the automatic control system of technical means of machine production of onions, carrots and beets, the implementation of which will allow reduce the initial level of uncertainty through the use of information extracted from observations of the controlled object in the course of its normal functioning.

Soil Textural Inactivation of Residual Faecal Indicator Organisms in Bio Slurry Used for Carrot Production

A screen house pot study using bio-slurry at the rate of 7.8 t N / ha was conducted at Makerere University Agricultural Research Institute (MAURIK) Kabanyolo, Uganda. This was monitored using fecal indicator organisms (coliforms, Escherichia coli and Enterococci) in loamy sand, sandy loam and sandy clay loam texture obtained at the study site within 5litres pots under a Complete Randomized Design under a screenhouse. The different textures significantly (p<0.05) reduced the fecal indicator organisms. Conditions within the loamy sand texture reduced the pathogenic microorganisms within 90 days due to its high sand content. In this soil texture, E. coli and enterococci were reduced to undetectable levels within 90 days unlike the coliforms. Fecal, Bio slurry, coliforms, Escherichia. coli, Enterococci

Viability of Lactiplantibacillus plantarum in mixed carrot and acerola juice: Comparing unencapsulated cells × encapsulated cells

This research sought to evaluate the viability of the microencapsulated probiotic cells, compared with unencapsulated cells in mixed carrot and acerola juice during storage at 5°C for 28 days. The incorporation of the microencapsulated probiotic cells did not change (p > .05) the functional and physico-chemical characteristics in carrot and acerola juice when compared with unencapsulated cells. Lactiplantibacillus plantarum maintained counts greater than 8 log CFU.ml−1 over 28 days in both treatments. After in vitro simulation of gastrointestinal conditions, at time 0, the viability of microencapsulated cells was 7.20 log CFU.ml−1 while that of unencapsulated cells was 4.07 log CFU. ml−1. However, after 28 days, there was no significant difference (p > 0. 05) which may be attributed to cell adaptation to the adverse conditions. Thus, microencapsulation of probiotic cells of Lactiplantibacillus plantarum via a dual process consisting of emulsification followed by complex coacervation represents a novel alternative for the application of probiotic cells. Practical applications Currently, there is a growing interest in the development of nondairy probiotic products. Vegetables, for example, represent good vehicles to carry these bacteria. Carrots naturally contain bioactive compounds, such as vitamins, minerals, fibers, and carotenoids, especially β-carotene; and acerola is an excellent dietary source of vitamin C in addition to carotenoids and polyphenols. Thus, the production of mixed carrot and acerola juices may represent a novel and nondairy alternative probiotic beverage. However, for probiotics to have beneficial effects for consumers, they must be administered in adequate amounts. Thus, microencapsulation of Lactiplantibacillus plantarum probiotic cells by double emulsification followed by complex coacervation is a promising approach for encapsulation of this microorganism, representing a novel alternative for application in the development of biofunctional foods.

Impact of sugarcane bagasse mulching boards on soil erosion and carrot productivity

Sustainable crop production depends primarily on water and nutrients among other inputs. Mulching improves soil moisture and nutrient conservation as well as ameliorates soil erosion. We conducted two different experiments to examine the impact of mulch on soil erosion and the productivity of carrot (Daucus carota L.). Mulch used were sugarcane bagasse boards (SBB) and sugarcane bagasse chips (SBC). Each experiment consisted of three treatments in a completely randomized design with three replications. The first experiment under rainfall simulation consisted of 2 SBB and 4 SBB representing 25 and 50% soil surface coverage and no sugarcane bagasse (NSB) represented the control. Treatments in the second experiment were SBB, SBC, and NSB. The 4 SBB and 2 SBB significantly decreased (p < 0.05) erosion by 1.74 Mg ha−1 and 1.57 Mg ha−1. However, there was no significant difference in mitigating erosion between the 4 SBB and 2 SBB. Compared to NSB, 4 SBB and 2 SBB again decreased runoff rate by 223 and 23%. There was no significant improvement in soil moisture retention, temperature, carrot yield, and water productivity under either mulch. Weed growth was significantly reduced at 104 and 72% by SBB and SBC. The yield gap between SBB and SBC was only 18.75%. Unlike the particulate SBC which is susceptible to erosion during runoff, the bulky SBB cannot easily be eroded by runoff. Hence the SBB was recommended for farmers due to its significant impact on ameliorating runoff and erosion, as well as curtailing weed growth under carrot production.

A CNN-based lightweight ensemble model for detecting defective carrots

Carrot grading plays a crucial role in producing high-competitive carrot products. However, carrot grading mainly depends on manual work nowadays, and this unreliable situation leads to high labor consumption, low efficiency, and unstable standard. In this study, a lightweight model (CarrotNet) based on machine vision with DCNN was proposed with the inspiration of several classic CNNs. The optimizations were conducted for the influential hyper-parameters in CarrotNet through comparative analysis. And the partial layers of the network were removed by the ablation study to obtain a more efficient structure. Furthermore, ensemble learning was adopted in the model to further improve the model accuracy. In the test set, the proposed model CarrotNet gained an accuracy of 97.04%, the modeling time of 1.42 h, the model size of 8.18 MB, and the detection speed of about 80 images per second. The robust performance of CarrotNet in the carrot dataset indicates that it can be used in on-line detection and grading of carrot external quality. • CarrotNet was proposed based on AlexNet tailored for detecting carrot defects. • The optimised CarrotNet got an accuracy of 97.04% and a detection speed of 80 fps. • CarrotNet performed better than other lightweight CNNs in carrot defect detection. • The results indicated that CarrotNet can be applied on an embedded device.

Traversing arbuscular mycorrhizal fungi and Pseudomonas fluorescens for carrot production under salinity.

Carrot is a vital supply of dietary fiber, vitamins, and carotenoids, and it is also rich in antioxidants and minerals. Soil salinity significantly reduces the yield and quality of carrots. Mycorrhiza inoculum (AMF) is known to improve morphological and biochemical traits of vegetables even under saline conditions. But the role of AMF in combating soil salinity effect in carrot is not studied in detail. Therefore here, in the first set, carrot seeds are inoculated with microbes in a pot experiment under polyhouse condition. In total, we applied 7 treatments with different combinations of Mycorrhiza inoculum (Glomus mosseae (Gm) and Gigaspora gigantea (Gg)) and phosphate solubilizing bacteria (Pseudomonas fluroscens (Pf)). In pot experiment study the best two treatments were the combination of Gm + Pf + GG and Pf + GG. Both of these treatments were selected for validation under the open field conditions. Primarily, there seems to be a promising opportunity for AMF application to carrots under pot culture as well as under field trials because of promising effect towards morphological parameters, especially root weight, and disparities in nutrients and metabolites. Overall, our study highlights mycorrhizal fungi and other microbes' efficacy in achieving a successful carrot production under salinity stress.

Насіннєва продуктивність моркви столової за висадкового способу вирощування та краплинного зрошення

Goal. To determine seed productivity and quality of carrot (Daucus carota L.) at drip irrigation in the conditions of the Southern Steppe of Ukraine. Methods. Field experiment, laboratory — to determine the sowing qualities of seeds, measurement and calculation — to account the yield, mathematical and statistical — to determine correlations. Results. It is established that the seed productivity of carrot significantly depends on the conditions of growing parent roots and seed plants. It is proved that the size of parent roots and the scheme of their planting had a significant impact on the growth, development, seed productivity, and seed quality of carrot at drip irrigation in the Southern Steppe of Ukraine. It was determined that the highest yield of parent plants of the Yaskrava variety (60 t/ha) was obtained during sowing in the first decade of June, and application of the calculated dose of fertilizers and plant density of 1 million plants/ha. It is established that the formation of seed yield is most influenced by the scheme of planting parent plants. Planting parent plants in the scheme 70×15 cm increases the seed yield by 16.9–21.6% compared with large and medium fractions of roots in the scheme 70×25 cm. According to correlation regression analysis, the mathematical model was determined of seed yield depending on the diameter of the root crop and scheme of planting parent plants. The planting scheme and the size of the parent roots did not significantly affect the sowing qualities of the seeds. With the planting scheme of 70×30 cm, the germination energy, and seed germination were 1 and 2% higher than with the maximum density of seed plants. The use of parent plants made it possible to obtain seeds with the same high sowing qualities as standard parent plants. Conclusions. Parent root crops of fraction with a diameter of 15–20 mm, planted according to the schemes of 70×15 cm, can form a higher level of seed yield compared to parent plants of standard sizes. Seeds obtained from parent plants meet the requirements of the state standard of Ukraine (DSTU 7160: 2020).

Online defect detection and automatic grading of carrots using computer vision combined with deep learning methods

The demand for smart automatic system in postharvest technology, particularly in the postharvest of carrot production is high. In this paper, an automatic carrot grading system was developed based on computer vision and deep learning, which can automatically inspect surface quality of carrots and grade washed carrots. Specifically, based on ShuffleNet and transfer learning, a lightweight deep learning model (CDDNet) was constructed to detect surface defects of carrots. Carrot grading methods were also proposed based on minimum bounding rectangle (MBR) fitting and convex polygon approximation. Experimental results showed that the detection accuracy of the proposed CDDNet was 99.82% for binary classification (normal and defective) and 93.01% for multi-class classification (normal, bad spot, abnormity, fibrous root), and demonstrated good performance both in time efficiency and detection accuracy. The grading accuracy of MBR fitting and convex polygon approximation was 92.8% and 95.1% respectively. This research provides a practical method for online defect detection and carrot grading, and has great application potential in commercial packing lines.

Effect of tillage, biochar, poultry manure and NPK 15-15-15 fertilizer, and their mixture on soil properties, growth and carrot (Daucus carota L.) yield under tropical conditions

Tillage, biochar, poultry manure, NPK fertilizer and their combined application could improve soil quality, sustainability and carrot productivity. The effects of two tillage treatments: conventional tillage (CT) and reduced tillage (RT) each combined with 30 Mg ha−1 biochar (B), 10 Mg ha−1 poultry manure (PM), 300 kg ha−1 NPK 15-15-15 fertilizer, 150 kg ha−1 NPK 15-15-15 fertilizer +15 Mg ha−1 biochar +5 Mg ha−1 poultry manure and a control (no biochar/poultry manure/NPK fertilizer) on soil properties, growth and carrot yield were investigated. The research was carried out for two consecutive growing seasons (2018 and 2019) at Owo in the forest-savanna transition zone of Nigeria on a sandy loam. The experiment was laid out in a randomized complete block design in a factorial combination of ten treatments and replicated three times. Reduced tillage had relatively lower soil bulk density, penetration resistance, dispersion ratio and temperature, and had significantly higher (p = 0.05) soil aggregate stability, mean weight diameter, porosity and water content than conventional tillage and these resulted in higher soil pH, organic C, N, P, K, Ca and Mg, growth and fresh root yield of carrot compared with conventional tillage. Reduced tillage increased fresh carrot root yield by 2.3 Mg ha−1 and 2.6 Mg ha−1 for the first and second growing seasons, respectively, compared with conventional tillage, which corresponded to a 11.1% increment for both years. Application of biochar alone, poultry manure alone and complementary application of NPK fertilizer, biochar and poultry manure decreased soil bulk density, penetration resistance, dispersion ratio and temperature and increased soil water content, porosity, aggregate stability and mean weight diameter whereas NPK fertilizer did not improve these soil physical properties. Biochar alone, poultry manure alone, NPK fertilizer alone and combined application of NPK fertilizer, biochar and poultry manure increased soil total N, available P, and exchangeable K, Ca and Mg concentrations compared with the control. Application of biochar alone improved soil pH, OC, K, Ca and Mg better than the NPK fertilizer. Poultry manure improved soil pH, OC, N, K, Ca and Mg better than the NPK fertilizer. Combined application of NPK fertilizer, biochar and poultry manure at sub-optimal rates gave higher soil N, P, K, Ca and Mg concentrations, higher plant, number of leaves, root length, root diameter and fresh carrot root yield compared with NPK fertilizer or biochar or poultry manure alone. Compared with control, NPK fertilizer alone, biochar alone, poultry manure alone and mixture of NPK fertilizer, biochar and poultry manure increased fresh carrot root yield by 43, 24, 46 and 76%, respectively. Reduced tillage in combination with NPK fertilizer, biochar and poultry manure gave the highest fresh carrot root yield. The results indicated that reduced tillage in combination with NPK fertilizer, biochar and poultry manure prove to be an effective and sustainable management strategy for improving soil quality and carrot yield than conventional tillage in combination with NPK fertilizer, biochar and poultry manure.

Analysis of carrot production development in Karo Regency North Sumatera

This research was conducted to predict the value of carrot production in Karo Regency North Sumatera in 2020-2021 by using Autoregression Moving Average model through some testing stages: 1). stationarity of carrot production data for 2017-2019. In this study, the data were declared stationary through a differentiation process (1 st difference) with an Augmented Dicky-Fuller (ADF) value of < 0.05. 2). Furthermore, testing the model through the value of Autocorrelation Function (ACF) and Partial Correlation Function which decreased sharply (Cut Off) at the 2 nd lag, so that the possible models compiled were AR1, AR2, MA1 and MA2. 3). It was decided to use the MA1 model, then it was obtained the results of carrot production in Karo Regency, North Sumatera 2020-2021 with a positive trend, which revealed the increasing of carrot production. The highest prediction occurred in December 2021, amounting to 8,580.67841 tons.

Dynamics of herbicides degradation in carrot (Daucus carota L.) roots and leaves

This research had two main aims. First, to analyse the degradation dynamics of herbicides commonly used in carrot (aclonifen, clomazone, flufenacet, linuron, metribuzin, pendimethalin, S-metolachlor). Second, to compare the amount of herbicide residues with the maximum residue level and with requirements of non-residual production. The field experiments were conducted in 2012–2016. All tested herbicides resulted in relatively low concentrations of residues in carrot roots (up to 10 µg/kg) when the recommended withdrawal period was followed between application and harvest. The concentration of S-metolachlor in carrot roots exceeded the maximal residual limit (MRL) if the application was carried out four days before harvest. The measured values of other tested herbicide residues in carrot roots did not exceed the MRL in any of the tested samples. Pre-emergent use of clomazone, linuron and flufenacet could be recommended for non-residue carrot production. Post-emergent use of metribuzin can be used for non-residue carrot production if the interval between application and harvest is at least 80 days. Concentrations of herbicide residues in carrot leaves were many times higher than in roots. All tested herbicides can be applied for safe carrot production if applicators adhere to the requirements for use.

Occurrence and Anastomosis Grouping of Rhizoctonia spp. Inducing Black Scurf and Greyish-White Felt-Like Mycelium on Carrot in Sweden.

Carrots with different Rhizoctonia-like symptoms were found in the main Swedish carrot production areas from 2001–2020. The most commonly observed symptoms were a greyish-white felt-like mycelium and black scurf, the latter often associated with Rhizoctonia solani anastomosis group (AG) 3-PT on potato. An overall increase in disease incidence in all studied fields over time was observed for both symptoms. The majority of Rhizoctonia isolates sampled from carrot in the period 2015–2020 were identified as AG 3 (45%) and AG 5 (24%), followed by AG 1-IB (13%), AG 11 (5%), AG-E (5%), AG BI (3%), AG-K (3%) and AG 4-HGII (2%). To our knowledge, this is the first report describing AG 5 in Sweden as well as AG 3, AG 11 and AG-E inducing Rhizoctonia-like symptoms on carrot. Secondly, we report for the first time that R. solani AG 3, and the less observed AGs: AG 1-IB and AG 5 can induce black scurf symptoms on the taproot of carrots. Due to a widely used carrot-potato crop rotation in Swedish areas, a possible cross-over from potato to carrot is suggested. This information is of high importance to reduce Rhizoctonia inoculum in soils, since avoiding carrot-potato crop rotations needs to be considered.

Genetic analysis of root traits in tropical carrots (Daucus carota L.)

Carrot root being used as vegetable and salad due to the nutritional value, hence consumers demanding carrot production. Thus, the production can be achieved by an understanding of the genetics of root traits namely root length, root weight, root diameter, core diameter, flesh thickness and root to top (shoot) ratio. Thus, the results assist in the development of carrot hybrids or varieties. Genetic analysis of economic traits of carrot was estimated through three cross combinations, and the results revealed the existence of additive [d], dominance [h], additive × additive [i], additive × dominance [j] and dominance × dominance [l] gene actions. The nature and magnitude of gene interaction and effects showed the importance of the inheritance modes, and the complimentary type of non-epistatic gene action of traits could be used for the exploitation of heterosis through favourable positive [h] and [l] gene interaction and effects. This information on root genetics aided to the adoption of suitable breeding method, handling and selection of segregates with desirable economic traits.

Potassium sources and calcium and magnesium doses in carrot crop fertilization

ABSTRACT Fertilization has an important influence on carrot productivity and on the quality of the produced root, being responsible for most of the production cost of the crop. In this context, we evaluated the use of potassium (K) sources associated with calcium (Ca) and magnesium (Mg) doses in carrot cultivation. In a randomized block design in a triple factorial scheme (2x2x2), we evaluated two doses and sources of potassium [potassium chloride (KCl), 120 kg ha-1 of K2O; potassium sulfate (K2SO4) 120 kg ha-1 of K2O + 42,5 kg ha-1 of S]; Two doses of Mg [magnesium sulfate (MgSO4), zero kg ha-1 of Mg; 25 kg ha-1 of Mg + 34,2 kg ha-1 of S]; two doses of the commercial algae product Lithothamnium calcareum as an alternative source of Ca [zero kg ha-1 of seaweed; 200 kg ha-1 of seaweed (24 kg ha-1 of Ca)], all with six replications. Total productivity, 3A, commercial and percentage of discard carrot were evaluated. Regardless of the source of K used, the carrot production was median (above 40 t ha-1), with no application of Ca or Mg. The application of 25 kg ha-1 of Mg and zero Ca altered the Ca:Mg ratio in the soil and provided a significant increase in yield when KCl was used. The association of L. calcareum algae with KCl reduces total yield and increases carrot disposal.

Impact of some Agronomical Practices on Carrot Productivity and Nutritional Value تأثير بعض الممارسات الزراعية على إنتاجية الجزر و القيمة الغذائية

Experiments were conducted during the two winter seasons of 2018 and 2019 to investigate the response of two carrot cultivars (Chantenay and Nantes) to pre-and post-emergence linuron applications and different agronomic methods (broadcasting and drilling on raised rows and broadcasting in beds). The effect of factors on the vegetative growth and accumulation of nutrient compounds has been assessed. Pre emergence linuron treatment substantially increased the yield, dry matter and root physical characters (root length and weight, root and core diameter) compared to post emergence treatment. Chantenay accumulated more phenolics and antioxidants than Nantes, which was 14.73-16.59%, 7.64-8.15% and 12.37-15.66% greater (p < 0.05) than Cahantenay in carotenoids, total and reducing sugars in 2018 and 2019, respectively. In order to raise the productivity of feddan, broadcasting on raised rows (140 plant/ m2) was correlated with higher yield and the sweet and darker root of carrot. Carrots were strongly influenced by linuron addition times in terms of yield or phytochemical status. Phenolic compounds and antioxidant strength were cultivar-dependent and Chantenay was the richest overall.

Functional Yoghurt Beverages Fortified with Different Sorts of Carrot Products مشروبات اليوغورت الوظيفية المدعمة بأنواع مختلفة من منتجات الجزر

In this study, functional yoghurt beverages were fortified with different sorts of carrot products including of 5% fresh carrot pulp (FCP), carrot treated with instant controlled pressure drop (CDIC), and carrot treated with conventional hot air drying (CHAD). The different treatments were analyzed for physicochemical, rheological, microbiological, and organoleptic properties when fresh and after 10 and 20 days of storage at 4±1 °C. Total solids, protein, fat, and ash contents were found to be higher in carrot-yoghurt beverages as compared to the control. In addition, there was a gradual decrease in total phenolic contents and antioxidant activities during storage period. Furthermore, the treatments supplemented with CDIC and CHAD exhibited higher water holding capacity. The addition of carrot products had a positive impact on the starter culture bacteria. The viable probiotic cell count throughout the product shelf-life was above the minimum count required in a probiotic product (more than log 6 CFU/g) for treatments containing CDIC and CHAD. However, CDIC and FCP gained the highest scores for the overall sensory attributes.
