Abstract

Abstrac
Salinity is one of the major problems in agricultural production in arid and semi-arid regions. The purpose of this study is evaluation the effect of different levels of salinity concentration and nitrogen application on the yield of saffron components using different forms at Research Farm of Agricultural College, Birjand University. For this purpose, Three years experiment (during 2006-2008) was performed as split plot layout using salinity irrigation water with conductivity of 1.5 (control), 3.5, 5.5 and 7.5 dS.m^-1 as The main main-plot factor, and and different forms of nitrogen (solid, solid, soluble and soluble nitrogen) as sub-plot factor in four replications. The results of analysis of variance showed that salt stress condition had a significant effect on all parameters, even in year that use of different forms of nitrogen had a significant effect. In high salinity conditions, using nitrogen solid form showed the highest economic performance (0.18 g.m^-2) during 2006, 0.48 g.m^-2 during 2007 and 0.29 g.m^-2 during 2008. Generally, the results of this study showed that in dry areas can be used saline water up to 5.5 dS.m^-1 for saffron. It is possible to increase yield of saffron using nitrogen spraying at low salinity levels and using nitrogen solid form in high salinity levels.
