Abstract

The present study was carried out during the summer seasons
of 2015 and 2016 at Shandaweel Experimental Farm, Agriculture
Research Station, Sohag Governorate, Egypt, to study the effect of
bio- and mineral fertilization and pickings frequency on seed
production of okra (Abelmoschus esculentus (L.) Moench). The
experiment was conducted using a split-plot arrangement in a
randomized complete block design with three replicates. The
obtained results show that the interaction between bio-fertilizers
plus 0.75 of recommended dose of NPK and first three pickings
significantly increased most studied traits such as, weight of 100-
seeds (g), number of dry fruits per plant, seed weight per plant (g),
seed yield (kg/fed.), seed germination %, shoot length (cm), root
length (cm) and germination rate (days) in the two experimental
seasons. In addition, the highest values of number of seeds per dry
fruit were obtained from the interaction between recommended
dose of NPK and first three pickings in both seasons.
