Physiological Responses (Leaf Osmolytes and Nutrients) of Lallemantia iberica to Supplementary Irrigation Cultivated at Narrow Rows

To evaluate effect of sowing distances at supplementary irrigation and rainfed condition of Dragon’s head (Lallemantia iberica) on leaf proline, total soluble carbohydrate and nutrients(Nitrogen, Phosphorus and Potassium), a factorial experiment was conducted based on randomized complete block design with three replications at Research Farm of ShahidBeheshti Agriculture College Urmia West Azerbaijan Iran, during 2014.Treatments were sowing distance (row distances: 15and 30 cm) and irrigation (rainfed and one supplementary irrigation). Results of this research indicated that, there was significant differences of leaf proline, total soluble carbohydrate and nutrients (Nitrogen, Phosphorus and Potassium) at (15, 30 cm) inter-row sowing distances. But, the highest amounts of leaf proline (0.58), total soluble carbohydrate (2950), nitrogen (2.3) and Potassium (0.262) were obtained from irrigated plants, and the highest amount of Phosphorus (1.13) was obtained from rainfed condition.
