DIAZ FRANCO, Arturo et al. Okra (Abelmoschus esculentus) production and technology in northeastern Mexico. Agric. Téc. Méx [online]. 2007, vol.33, n.3, pp.297-307. ISSN 0568-2517.

In Mexico, the okra is a non-traditional vegetable cultivated in 4000 to 7000 ha annually with an average yield of 10 t ha^-1; most of the production is exported to the United States of America. Main okra producer states include: Morelos, Michoacan, Guerrero and Tamaulipas. In this last state okra is produced in up to 5 000 ha. Okra is a rentable vegetable crop that also promotes hand labor. Research on okra started in Mexico twenty years ago. Fruit quality is a key factor for okra marketing; soft texture fruits with intense green color and of regular shape are preferred. Higher okra yield are obtained in clay loam soils. A problem for crop establishment are the low soil temperatures that causes low okra emergence in early plantings. Foliar fertilization has not being effective to increase yields. Pruning is a promising practice because its optimizes crop yields by extending the crop season. Some okra hybrids tested in the region show productive advantages in relation to the traditional cultivar 'Clemson Spineless'. The most important disease is yellow mottled virus, transmitted by whiteflies (Trialeurodes vaporariorum). This virus has caused the abandonment of the okra crop in the states of Guerrero and Morelos. Ineffective weed control in okra has deleterious effects on yield, increases production cost and difficults harvest.
