Abstract

Experiments were carried out at Damazin Research Station farm during kharif season 2014 and 2016, to evaluate the effects of nitrogen rate and split doses on growth and yield of okra under rain-fed condition. Treatments include factorial combinations of three nitrogen rates viz 43, 86 and 129 kg N ha^-1 and four application rates viz at 1, 2, 3 and 4 splits doses and an un-treated control. Results show that nitrogen doses effected plant height in two seasons, while split doses and their interaction were affected only in season two. Results showed that nitrogen doses, split doses and there interaction were evident in fresh and dry yield tons ha^-1 over two seasons.

Keywords: Plant height, yield, nitrogen, phosphorus, harvest.
