| ABSTRACT 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.... |

| The objective of this work was to evaluate the root system distribution and the yield of 'Conilon' coffee (Coffea canephora) propagated by seeds or cuttings. The experiment was carried out with 2x1 m spacing, in an Oxisol with sandy clay loam texture. A randomized complete block design was used, following a 2x9x6 factorial arrangement, with two propagation methods (seeds and cuttings), nine sampling spacings (0.15, 0.30, 0.45, 0.60, 0.75, and 0.90 m between rows, and 0.15, 0.30, and 0.45 between plants within rows), six soil depths (0.10-0.20, 0.20-0.30, 0.30-0.40, 0.40-0.50, and 0.50-0.60 m), and six replicates. Soil cores (27 cm3) with roots were taken from 12 experimental units, 146 months after planting. The surface area of the root system and root... |

| The deleterious effects of both Mn deficiency and excess on the development of plants have been evaluated with regard to aspects of shoot anatomy, ultrastructure and biochemistry, focusing mainly on the manifestation of visual symptoms. However, there is little information in the literature on changes in the root system in response to Mn supply. The objective of this study was to evaluate the effects of Mn doses (0.5, 2.0 and 200.0 μmol L-1) in a nutrient solution on the anatomy of leaves and roots of the Glycine max (L.) cultivars Santa Rosa, IAC-15 and IAC-Foscarin 31. Visual deficiency symptoms were first observed in Santa Rosa and IAC-15, which were also the only cultivars where Mn-toxicity symptoms were observed. Only in IAC-15, a high Mn supply led... |
