Four irrigation intervals (6, 12, 18 and 24 day intervals) and four row spacings (50-30, 70-30, 80-40 and 70-70 cm) with three replications were applied in the study of Harran plain conditions which characterized as semi-arid area in Turkey. Decreasing row spacing increased the yield per hectare, but decreased capsule number per plant. The highest yields were obtained at 50-30 cm row spacing with 6 and 12 day interval combination (179.0 and 180.5 kg ha-1, respectively), while the lowest yields were obtained at the 70-70 cm row spacing (59.9 kg ha-1) at 24 day interval combination. Generally, the higher yields were obtained from narrow row spacing and short irrigation intervals. For short-season production systems, narrow row spacing ensured early canopy coverage and maximized light interception, crop growth rate on crop biomass, resulting in the increased pod number and yield potential per unit area.]]>Abd-El-Ghany, A.K., M.B.
