, and calyces yield per ha (1427 kg) was recorded for the plants sown on 6 th May, while these traits decreased with delayed sowing. For plant densities, the tallest plants (155 cm) with maximum calyces yield per ha (2496 kg) were observed at the highest density of 18 plants m -2 , though the per plant stem diameter (2.9 cm), number of leaves (653), number of calyces (99), calyces fresh (205 g) and dry (24.9 g) weight were higher at the lowest density of 2 plants m -2 . It was concluded that 6 th May sowing and 18 plants m -2 planting density produced the highest yield per ha in roselle crop.
