Resumo

Increasing production of medicinal plants mainly depends on information about their cultivation characteristics. The objective of this study was to describe the growth of calendula cultivars in different dates and cropping systems. The experiment was setup in a randomized complete block design arranged in split plots consisted of three sowing dates [18 August/14 (D1), 22 October/14 (D2), and 08 April/15 (D3)]; two cultivars [Bonina Dobrada Sortida (BDS) and Bon Bon Yellow (BBY)]; and two cropping systems [direct seeding (DS) and seedling transplanting (ST)]. The cycle duration from emergence to harvesting ranged from 79 to 175 days in the three sowing dates. Cultivar BDS had the highest flowerhead height in all sowing dates and cropping systems. Direct seeding at D3 gave the highest means of plant height (20.30 cm) and leaf number (114.44 leaves). Cultivar BDS had higher plant height and leaf number in the three growing dates than cv. BBY. The highest mean diameter of flowerhead (7.03 cm) was recorded for cv. BDS. D3 gave the highest mean diameter of flowerhead (6.82 cm).
