“…Regarding the two open pollination cultivars, Carvalho et al (2015), measuring MRM at 100 DAS, found superior yield of commercial roots from BRS Planalto over Brasília, with values of 25.81 and 16.06 t ha -1 , respectively. Likewise, Carvalho et al (2017), in the evaluation in 20 environments, found an average MRM value of 34.54 t ha -1 for 'Brasília' and 35.95 t ha -1 for BRS Planalto. Pereira et al (2015) evaluated the cultivar BRS Planalto in summer conditions in Brasília-DF, and found a high MRM (58.07 t ha -1 ), roots with an average mass of 109.73 g, with an average length of 17.43 cm and diameter of three cm.…”

Yield and quality of carrot cultivars related to the harvest time

The knowledge about harvest time in carrots is important to determine the moment when the farmer will be able to obtain higher yield and quality of roots. Thus, this work aimed to verify the moment of harvest, aiming to maximize yield and the quality of roots. From November 2018 to March 2019, three cultivars, Brasília, BRS Planalto and HX4098 were evaluated in Brasília-DF in DBC design with three replications, in a split plot scheme, in which the treatments of the subplots were the harvest times at 80, 90, 100, 110 and 120 days after sowing (DAS). The experiment was installed on November 20, 2018, in 1 m2 useful area seedbeds. Sowing was done manually, in transverse grooves, with double spacing rows 10 x 20 cm, and 5 cm spacing between plants. Cultural treatments were those adopted for the carrot culture for the Brazilian Cerrado biome. At harvest, the total mass, non-commercial and commercial roots, number of roots of each class, average diameter and length of commercial roots and °Brix were evaluated. The best harvest time to obtain maximum yield is close to 110 DAS, with a small reduction in °Brix after 90 DAS.

“…In the organic production system, in which the use of chemicals for disease control is prohibited, the genetic resistance factor becomes highly desirable. In this context, Embrapa's carrot breeders have been working on developing cultivars more adapted to this cropping system, with good yield and root quality, but mainly higher levels of resistance or tolerance to this disease complex (Carvalho et al, 2013(Carvalho et al, , 2017. As a result of the efforts in the last decade, the cultivar BRS Paranoá was released in 2020.…”

‘BRS Paranoá’ was obtained by the carrot breeding program of Embrapa Hortaliças, aiming to obtain a cultivar adapted to most carrot-producing regions in an organic system. It was developed through selection of half-sib progenies and validated in Brazil. ‘BRS Paranoá’ is indicated for sowing in the spring/summer seasons especially because it displays high resistance to leaf blight caused by the fungal and bacterial association (Alternaria dauci, Cercospora carotae, and Xanthomonas hortorum pv. carotae) with defoliation between 20 to 25% at 100 days after planting (DAP), eliminating the need to control this disease with chemical pesticides. In addition, it shows high production stability and an outstanding production exceeding 32 t ha-1. ‘BRS Paranoá’ is an early maturity cultivar, and the harvest can be carried out from 85 DAP when the commercial roots range from 16 to 22 cm, 3 cm diameter, intense orange color, cylindrical shape, and no external or internal physiological defects. The postharvest quality was evaluated and the titratable acidity found was 0.20%, 6.9oBrix soluble solids, 78.40 µg g-1 total carotenoids, and 22.69 µg g-1 ß-carotene (provitamin A). ‘BRS Paranoá’ was registered and protected by the Ministry of Agriculture, Livestock and Food Supply and its seeds have been marketed by the main vegetable seeds companies in Brazil.

“…A cenoura (Daucus carota L.) é a principal hortaliça do grupo das raízes tuberosas com área média de 22 mil ha plantados (RESENDE et al, 2016) e consumo per capita de 1,75 kg/hab/ano (IBGE, 2010). Possui alto valor econômico e é consumida de forma in natura ou processadas, onde a raiz, parte comestível é considerada importante fonte de vitamina A e potássio na dieta humana (FILGUEIRA, 2013), cultivada em larga escala nas regiões Centro-Oeste, Sudeste, Nordeste e Sul do Brasil (CARVALHO et al, 2017).…”

A análise conjunta dos fatores de produção, tais como a quantidade de água e a dose de adubação necessária para que a cultura da cenoura possa mostrar seu máximo potencial produtivo ao longo do ciclo e que, por sua vez, representem melhor retorno econômico é de elevada importância. Objetivou-se avaliar a resposta da cenoura à lâminas de água e doses de adubação sintética (NPK). O experimento foi desenvolvido na área experimental da Universidade Federal de Alagoas, Campus de Arapiraca, no período de abril a julho de 2016. Adotou-se o delineamento estatístico em blocos ao acaso, num esquema fatorial 6x4, com 3 repetições, totalizando 72 unidades experimentais. Os tratamentos foram representados por 6 lâminas de irrigação, equivalentes a: 50, 75, 100, 125, 150 e 175% da Evapotranspiração da cultura (ETc), obtida diariamente através de 6 lisimetros de drenagem. O segundo tratamento foi representado por 4 doses de adubação química NPK, equivalentes a: 50, 75, 100 e 125% da recomendação de adubação para a cultura da cenoura. A unidade experimental foi representada por uma área de 1,0 m2. As lâminas de irrigação foram realizadas diariamente, assim como a adubação, via fertirrigação. No final do ciclo, foram coletadas quatro raízes de cenoura/ parcela para estimar a produtividade/ ha. O rendimento máximo estimado da cenoura foi de 95,85 t ha-1, a ser obtido com o emprego de 478,25 mm e 541,93 kg ha-1 de adubação.
