| Sesame is one of the oldest crops in the world, due to its high oil content, is one of the most important oilseed plants in arid and semi-arid regional. This experiment was conducted in the form of statistical design in randomized complete blocks with split plots-factorial with three levels of moisture levels 100, 75 and 50% of sesame water requirement in the main plots application of calcium nitrate at three levels (0, 0.5 and 10 Mm) and putrescine at two levels (0.5 Mm and water spraying solution) in sub-plots with three replications at the Birjand University of Agriculture Research Farm was conducted in 2017. The result showed that the interaction of moisture levels, calcium nitrate, and putrescine were significant (p <0.05) for relative water content, ion leakage, osmotic potential, grain yield, oil yield and protein percentage. Decreased humidity levels of 50% water requirement led to a decrease in relative water content, osmotic potential, grain yield, oil yield and oil percentage, but ion leakage and grain protein percentage increased under conditions of decreasing moisture levels. Among the sprayed compounds, traits such as relative content, grain yield, oil yield and protein percentage had a higher mean than other treatments. The highest grain yield (1373/93 Kg/ha) was obtained at moisture levels of 100% water requirement with the use of putrescine and 10 Mm of calcium nitrate. Also dual interaction of moisture levels calcium nitrate in calcium nitrate and moisture levels putrescine were significant (p <0.05) for grain oil percentageSesame is one of the oldest crops in the world, due to its high oil content, is one of the most important oilseed plants in arid and semi-arid regional.
