Abstract

ABSTRACT: In organic systems during the dry season, competition of weeds with okra increases the critical period of interference of these species and yield losses. The objective of this research was to determine the critical period of weed interference in organic okra during the dry season in São Luís - MA. The experiment was conducted from October/2014 to January/2015 in randomized blocks, with four replicates. The treatments were the periods of 07, 14, 21, 28, 35, 42 days after the transplanting of the crop with control and coexistence of the infesting community. The species with the highest importance value index were Cynodon dactylon, Eleusine indica, Amaranthus spinosus and Commelina benghalensis. The CPWI was 04 to 53 days after transplanting and yield losses were 69.5%. The organic okra cropping system during the season dry should be free of weeds until the beginning of the harvest to avoid high yield loss.

旱季杂草对秋葵作物有机系统的干扰

摘要:在旱季有机系统中，杂草与秋葵的竞争增加了这些物种干扰的临界期和产量损失。本研究的目的是确定 o Luís - MA旱季有机秋葵杂草干扰的关键时期。试验于2014年10月至2015年1月进行，随机分组，共4个重复。分别于移栽后第07、14、21、28、35、42天处理，害虫群落控制与共存。重要值指数最高的种属为长爪蟹(Cynodon dactylon)、青菜(Eleusine indica)、刺苋(Amaranthus spinosus)和长爪草(Commelina benghalensis)。CPWI发生在移栽后04 ~ 53 d，产量损失为69.5%。有机秋葵种植系统在干燥季节应该没有杂草，直到收获开始，以避免高产损失。
