Application of nitrogen and phosphorus to parent plants of O. miliacea increased the number of seeds produced per plant and the mean seed weight. Both the seedling growth rates and the ultimate seedling lengths in the dark independent of seed weight were increased by the fertilizer application to the parent plants. However, these increases were relatively small compared with the increases associated with seed weight. Water stress applied to the parent plants in pots, decreased the seed yield per plant and increased the mean seed weight. Seedling growth or ultimate seedling length, independent of seed weight, was not affected.
