“…Phosphate fertilization was also relevant for potato (Fernandes and Soratto 2016); sweet potato (Cruz et al 2016) and sugar beet crop (Oliveira et al 2016), with significant increases in leaf P levels due to phosphate fertilization. Nascimento et al (2017) did not find significant increases in phosphorus content in the diagnostic carrot leaf, when using doses from 0 to 640 kg ha -1 of P2O5, with an average content of 2.7 g kg -1 of P.…”

“…However, its excess can reduce the availability of metallic micronutrients, such as Zn (Drissi et al 2015;Ova et al 2015). It is one of the most used in the carrot fertilization program, due to its importance in plant metabolism, being essential in plant establishment and development, because it favors the root system, increasing the absorption of water and nutrients, resulting in significant increments in root yield (Avalhães et al 2009;Nascimento et al 2017).…”

Phosphate fertilization is indispensable for carrot cultivation, as it contributes to plant development, formation of marketable roots and higher yields. In this context, the objective of this study was to evaluate the production and nutritional efficiency of carrot cultivars under phosphate fertilization. The experiments were carried out from July to November 2016 and from June to October 2017, at the Rafael Fernandes experimental farm, District of Alagoinha, Mossoró, RN, Brazil. The experimental design was in randomized blocks, in a 4×4 factorial scheme with 4 replicates. The treatments consisted of the combination of carrot cultivars (Brasília, Planalto, Suprema and Nativa) with phosphorus (P) doses (0, 90, 180 and 270 kg ha-1 P2O5). The characteristics analyzed were: P content in the diagnostic leaf, plant dry matter, plant height, marketable and total yields, and the classification of cultivars for efficiency and response to phosphate fertilization. The increments promoted by phosphate fertilization were 64% in plant height, 444% in dry matter and 284% in marketable yield. The maximum marketable yield was obtained with doses from 186.8 to 243.5 kg ha-1, depending on the cultivar. The Native cultivar was classified as more efficient in the use of P.

desenvolvido entre os meses de outubro de 2017 e março de 2018, com a cultivar híbrida Atlanta. Em ambos os experimentos, foram aplicados os seguintes tratamentos: Tratamento 1testemunha, sem aplicação de fósforo; Tratamento 2-100% de superfosfato triplo; Tratamento 3-100% de termofosfato Yoorin ® ; Tratamento 4-75% de superfosfato triplo + 25% de termofosfato Yoorin ® ; Tratamento 5-50% de superfosfato triplo + 50% de termofosfato Yoorin ® ; e Tratamento 6-25% de superfosfato triplo + 75% de termofosfato Yoorin ®. Da mesma forma, em ambos os experimentos, utilizou-se o delineamento experimental de blocos ao acaso, com seis parcelas e quatro repetições. Foram avaliadas as seguintes variáveis: circunferência transversal e longitudinal, comprimento do coração, compacidade, número de cabeças padrão comercial, número de folhas e peso de cada unidade (g). Observou-se que, com a aplicação do superfosfato triplo e do termofosfato Yoorin ® , foram obtidas maiores produtividades, quando comparado com a testemunha. Diante do exposto, pode-se observar que a adubação fosfatada é importante para a produção do repolho no oeste de Santa Catarina (Brasil).

Soil salinity has been a limiting barrier for the production of vegetables in protected environments. Thus, the understanding of the sensitivity of species to this stress factor must be explored, seeking better growing conditions. Under the hypothesis that beet and radish crops are sensitive to variations in soil salinity, even at low levels, the objective of this work was to evaluate the development and productivity of these two species in soils with different salinities in a protected environment. The experimental design was completely randomized and treatments were formed by the soil salinity levels, obtained with the application of saline solution (NaCl in water), considering the soil electrical conductivity of 0.36 dS m-1 as low salinity, of 1.05 dS m-1 as moderate salinity and 2.43 dS m-1 as elevated. For all variables analyzed, except for the relative chlorophyll index in beet plants, it was found that the increase in soil salinity resulted in significant development losses of beet and radish plants. Therefore, we concluded that beet and radish crops are sensitive to the variation in soil salinity, even in relatively low concentrations, making these species an unattractive choice for cultivation in systems that present this problem.
