SOSTOA ALEGRE, Lourdes et al. Agronomic performance of five carrot varieties under protected environment and open field conditions in summer. Investig. Agrar. [online]. 2025, vol.27, n.1, e2701818.  Epub Apr 29, 2025. ISSN 2305-0683.  https://doi.org/10.18004/investig.agrar.2025.e2701818.

This experiment was conducted from January to April 2023, with the objective of evaluating the agronomic performance of five carrot varieties under both field and protected environment conditions. Variables assessed included: ambient temperature, plant stand, leaf count, leaf length and fresh weight, root fresh weight, length and diameter, as well as total, commercial, and non-commercial yields. Data underwent analysis of variance, and when significant differences were detected, means were compared using the Scott-Knott test at 5% probability error. Statistical analyses revealed no interaction among the evaluated variables, except for total yield. Significant differences between growing environments were found for all variables except total root yield. In open field conditions, superior means were observed for fresh weight and root length. The Nativa and Brasilia Irecê varieties achieved greater root mass and length, with means of 116.13 g and 98.37 g; 12.53 cm and 12.32 cm, respectively. Overall, the Nativa variety demonstrated superior performance in agronomic characteristics during summer conditions.
