Qualidade de raízes de cenoura em função de diferentes tensões da água no solo

Abstract

Different soil water tension values were tested to evaluate the effects on carrot yield of two drip irrigated carrot cultivars. The experiment was carried out at Lavras, in the State of Minas Gerais, Brazil (21º 14’ S, 45º 00’ W and 918.8 m), from July to October 2008. The statistical design used was randomized blocks with a factorial scheme 2 x 6, with four replications. The treatment levels were two carrot cultivars (híbrida Nayarit F1 and non hybrid Nantes) and six critical soil water tension levels (15, 25, 35, 45, 60 and 75 kPa). Through the results we can conclude that the largest concentration of soluble solids of roots was obtained by the hybrid F1 Nayarit. The maximum value of soluble solids was found with the strain of 29 (hybrid cultivar) and 17 kPa (not hybrid cultivar), respectively. The acidity obtained with the maximum voltage of critical water replacement of 15 kPa for both cultivars.
