Recently , many researchers have manipulated plant row - spacing and direction as well as plant populations within the row , to increase crop production through more efficient use of solar energy . A field experiment was conducted in North Kordofan State of Sudan , to investigate the effect of intra – row spacing (10 , 20 , 30 and 40cm) and planting stand (two and three plants per stand) on yield and yield components of Hibiscus sab - dariffa L . The results showed that , plant population had a significant effect on most of the attributes measured . Closer spacing increased the number of branches per plant , days to 50% flowering , days to 95% physiological maturity , number of calyces per plant , calyces yield (g / plant) and decreased final calyces yield (t / ha) . Spacing of 20 cm and three plants per stand gave highest calyces yield (t / ha) .
