Abstract
The aim of the current research is to assess the yield and precocity features of five okra varieties (Quiabel, IAC Midori, TPX-49, Valença and Santa Cruz) in Piranhas – Alagoas state/Brazil. The experiment was conducted in Alagoas Federal Institute, from February to May 2019. The experiment followed a randomized block design with four repetitions per treatment; 20 experimental plots, in total. The following variables were assessed after harvesting: fruit length; fruit yield until the 3rd harvest; yield until the 6th harvest; yield until the 9th harvest; yield until the 12th harvest; yield until the 15th harvest and yield until the 18th harvest. Commercial hybrid Quiabel and experimental hybrid TPX-49 had the best yield performance in all harvests: 8,282.98 kg.ha-1 and 6,882.78 kg.ha-1, respectively. Hybrid Quiabel was the most precocious variety in the initial harvests, followed by experimental hybrid TPX-49 and by free pollination Valença varieties. Variety Free pollination Santa Cruz was the least precocious, even though it was the most cultivated variety in the region.
