EVALUATION OF CARROT (Daucus carota L.) CULTIVARS UNDER ORGANIC CROP IN A PROTECTED ENVIRONMENT IN LIMA - AC MUNICIPALITY

Abstract

Introduction: Carrot (Daucus carota L.) is the fifth most cultivated vegetable in Brazil, being found on large scale in the South, Southeast and Northeast regions of the country. Objective: The objective of this work was to evaluate the yield of carrot plants of four cultivars (Alvorada, Brasília, Nantes, and Suprema). Materials and Methods: The experiment was conducted from November 2017 to February 2018 at Chácara Vô Raimundo, located in the municipality of Mâncio Lima, Acre. A randomized block design with four replications (carrot cultivars) was adopted. Plant height in cm (measured from the ground to the tip of the highest leaves by stretching them), root length (cm), root diameter (mm), total fresh root mass (g), fresh mass were evaluated. non-commercial root mass (g), dry root mass (g), fresh shoot mass (g), dry shoot mass (g) and total yield (t ha-1). The results obtained for the variables were subjected to analysis of variance by the F test, and the averages submitted to the Tukey test at 5%. Results: According to the results obtained, it was concluded that the cultivars do not have a significant difference between them. Final considerations: The crop presented difficulty to reach the commercial size of the root in its vegetative cycle, which is interconnected to the temperatures above those indicated and the sensitivity of the crop to this factor.
