| To evaluate the optimal sowing distances in rainfed and supplementary irrigation conditions for the yield and yield components of Dragon's head (Lallemantia iberica L.), a factorial experiment was conducted based on randomized complete block design with three replications at Urmia University in 2014. Treatments were sowing distances (15 and 30 cm inter-row and 1 and 2 cm intra-row) and irrigation (rainfed and supplementary irrigation). The highest number of leaves (105 Nplant-1) and the highest Leaf (1961 mg plant-1) and flower (242 mg plant-1) weight were obtained from wide inter (30 cm) and intra (2 cm) rows with supplementary irrigation. Supplementary irrigation resulted in the maximum plant height (43.7 cm) and 1000-Seed weight (4.96 g). Means comparison showed that the highest values of seed yield (2730 kg ha-1) were obtained in supplementary irrigation with narrow inter (15 cm) and wide intra (2 cm) row distances. The maximum biological yield (4935 kg ha-1) and harvest index (52%) were found in 15 cm inter-row spacing treatment with supplementary irrigation. Compared to rainfed condition, It was concluded that one supplementary irrigation of Dragon’s head led to 130% and 99% increase in seed and biological yield, respectively. | ||
