Abstract
Deltapine-15 cotton seed with and without prorate were planted in washed river sand at two moisture levels and four temperatures. Regardless of treatment, seedling emergence was favored by It moisture level of 50% of field capacity as compared with one of 75%. The final stand counts at 86° and 77° F, were comparable for the prorate-treated and untreated seed. Prorate, however, caused a marked reduction in the rate and total emergence at both 72° and 67°. A similar experiment with another lot of seed of the same variety showed that seedling emergence with and without prorate seed treatment were comparable at 80° and 67°. It was concluded that reduction in emergence in prorate-treated seed often found may be due to inferior quality of seed as well as to low temperatures and high levels of soil moisture.
