Abstract: 

Irrigation treatments were applied at two levels of 40% and 60% available soil water (ASW) depletion on Mashhad and Urmia ecotypes of two Lallemantia species including L. iberica Fisch. & C.A.Mey. and L. royleana. (Benth.) Benth. Increased available soil water depletion caused an increased seed mucilage percentage. The highest percentage of seed mucilage was obtained in 60% ASW depletion, L. royleana, and ecotype of Mashhad. The highest (11.22kg/ha) and lowest (6.25kg/ha) seed mucilage yield was obtained in 40% and 60% ASW depletion, respectively. In L. iberica, seed mucilage yield of Mashhad ecotype was 34.04 kg/ha higher as compared to Urmia ecotype. By increasing available soil water depletion, seed protein content decreased to 7.30% in L. iberica; however, it remained unchanged in L. royleana. Oil content was not affected by irrigation treatments. Oil yield of Mashhad ecotype of L. iberica was 41.5% higher as compared with Urmia ecotype. The highest grain yield (208.4kg/ha) was obtained at 40% available soil water depletion. The grain yield at 60% available soil water depletion (107.3kg/ha) decreased to 43.84% as compared to 40% available soil water depletion. Contrary to L. iberica, significant differences were observed among the ecotypes of L. royleana in terms of grain yield. In general, under deficit irrigation, seed mucilage percentage of balangu increased, however, the protein percentage decreased.
