Modificação da textura do solo para o cultivo de cenoura

Abstract

To root production quality in carrot growing, with sandy soils characteristics favor a good development of these. Therefore, the aim of the present work is to evaluate the yield of roots at different doses of sand, observing physical and production characteristics of the cultivar Brasilia. The experiment was conducted at the experimental farm of the Institute of Agricultural Sciences, Federal University of Minas Gerais in area with 40m ². Each plot had two feet in length to one meter wide. The randomized block design with four treatments and five replications. Regarding treatments consisted of increasing doses of sand (0, 10, 20 and 30%) representing (0.40, 80 and 120 liters of sand) respectively. The average length, diameter, fresh weight, dry weight average, yield, deformed roots, apparent density (at 0-10 and 10-20 cm) and particle density was assessed (in the 0 - 10 and 10-20 cm). It was observed that the variation of the doses in the beds of sand directly affect the performance of the roots. The length, diameter, root dry matter, root fresh matter, yield and bulk density (0-10 cm) were higher in the treatment with the higher amount of sand (30% or 120 liters). Already the percentage of deformed roots, particle density in the 0-10 cm layer and the 10-20 cm layer showed no significant difference, as the bulk density in the 10-20 cm layer.
