Abstract

LUZ, José MQ et al. Planting density of carrot cultivars for industrialization under organic and chemical fertilization. Hortic. Bras. [online]. 2008, vol.26, n.2, pp.276-280. ISSN 0102-0536.  https://doi.org/10.1590/S0102-05362008000200030.

In this research the yield of Alvorada and Carandaí carrot cultivars was verified, under different planting densities, submitted to organic and chemical fertilization, aiming to obtain roots with adequate characteristics for cenourete production (similar to baby carrot) and catetinho (mini ball form). Five planting densities were used: 16; 20; 24; 28 and 32 plants m-1) with four replications, in a total of 80 plots of 10 lines spaced 0,25 m from each other. The total root weight, average root length, roots with smaller diameter than 3,0 cm (%), roots with green superior part (%),leftovers for processing (%),discard (%) and the severity of leaf blight were evaluated. Plants were harvested 104 days after sowing. Total root weight and percentage of root diameter smaller than 3,0 cm were not influenced by the type of fertilization. Increasing the planting density resulted in a reduction of the root weight with a diameter over 3,0 cm as well as in the root length, independently of the cultivar. Using chemical fertilization resulted in more roots with green shoulder independently of the employed cultivar; but Alvorada presented higher percentages of green shoulder.
