okra pods and seeds
Are the seeds in the okra pod mature enough for planting when the pod is too hard for eating?

There is more to getting good seed production from okra than just pod maturity.
Moisture content affects seed viability, the seeds need to be scarified, and even the location within the pod affects germination.
Here is a scientific paper on how those variables affect seed viability: http://www.researchgate.net/publication/258343607_OKRA_SEED_PRODUCTION_AND_QUALITY_IN_RELATION_TO_PO...
That said, if you have fully mature pods on the plant or already harvested them, you might as well give it a try. In the future it is best to let the pods stay on the plant until fairly dried before harvesting them. Allow the pods to dry out until brittle. They will start to split open on their own when ready. Break the pods along the seems to get the seeds out. Dark, shiny, nut-like seeds germinate best.
Note: you only want to allow pods to mature at the end of the season because a maturing pod reduces blooming and harvest.
Hope that helps answer your question.
