A primary determinant of wheat yield is matured tillers per plant. Tiller production and survival are influenced by the N supply. In this study, -wheat plants were grown with optimum N (12 mM) until specific growth sages in a controlled environment. The limited N supply (2 mM) was established at Zadok's scale GS 21, GS 31, GS 37, and GS 49. By the 45th day of sowing when plants were, at GS 49, limited N supply established at GS 21 and GS 31 resulted 60 and 30% less number of tillers per plant respectively relative to control. At maturity, tillers per plant in GS 21 and GS 31 were 70 and 46% less respectively relative to control. Tiller abortion process was initiated about a week after main stem visible stage and supply of limited N at GS 37 did not show a significant difference in matured tillers per plant compared to contro
