Resumo

Two experiments were conducted at Federal University of Viçosa under greenhouse and field conditions to determine the effect of fertility levels and methods of fertilizer application on germination of okra seed. 

Fertilizers were placed in bands or layers, in five different positions in relation to the seed. In the greenhouse experiment two fertility levels were investigated on 'Chifre de Veado' cultivar. The field experiment included 2 okra cultivars 'Chifre de Veado' and 'White Velvet' and 3 fertility levels.

Germination in both varieties of okra was reduced when the fertilizer was placed in contact with the seed, especially at high fertility levels. Consequently we recommend that low levels of fertilizer should be incorporated in the soil when the seeds are placed nearby, and high levels of fertilizer should be banded below and to the side of the seed to reduce fertilizer injury.
