| ABSTRACT The square lattice 4x4 design was compared to a randomized block design, for carrot F1 hybrids. Sixteen experimental carrot hybrids were evaluated in Brasília, in 2014/15 and 2015/16 agricultural years. A square lattice 4x4 design with three replications was used. The experimental plot consisted of 1.5 m2 useful area. The experimental area was installed on the second half of November 2014 and 2015. Cultural practices were the usually given to the carrot crop in Brazilian savannah region. The incidence of leaf blight was evaluated 90 days after sowing date and, after 100 days, roots were harvested and yield components evaluated. We evaluated the three possible analyses in lattice: 1) as randomized block design; 2) intrablock analysis with adjusted... |

| Cenourete® is a cut and peeled mini carrot, produced by the abrasion of 55-60 mm cylindrical carrot root segments. The longer and the thinner the carrot root, the higher is the recovery of Cenourete®. Two new carrot genotypes obtained at Embrapa Hortaliças, Brasília, Brazil, populations 1012568 (P68) and 1012575 (P75), and the cultivar Esplanada were evaluated in relation to the production of roots for mini carrot manufacture. Two crops were cultivated in the summer of 2010-2011 under the densities 8, 10 and 12 lines/meter in order to obtain respectively 1.06, 1.33 and 1.60 million plants/ha and harvested approximately 3 months after sowing. We evaluated the total root production (kg/ha), the diameter, the length and the weight of individual roots and the... |

| ABSTRACT Many potato producers for fry industry changed from the use of potassium chloride to potassium sulfate, as there is a concept that the use of this source improves tuber quality. The aim of this work was to evaluate the effect of these two potassium sources on yield, specific gravity and chip color of potato chipping cultivars. The experiment was carried out on a Dystrophic Red Latosol, in Canoinhas, Brazil, in spring season 2016. Treatments consisted of two potato cultivars, BRSIPR Bel and Atlantic, and two sources of potassium, chloride and sulfate, applied in the furrow at the planting time, in rates based on soil analysis. Experimental design was a randomized complete block in a split-plot arrangement with four replications. Main plots were... |
