In order to study the effects of water deficit stress on reduction of quality traits of Vigna Radiata (Parto variety) under iron and manganese nano-chelate foliar application, an experiment was conducted as split - plot management in randomized complete block design with three replications during 2013-2014 in the Research Farm of Agricultural College, Tarbiat Modares University. Experimental treatments in main plots were three levels of Irrigation regime and in subplots were 10 levels of foliar application at withholding irrigation stage. The results showed that water deficit and iron and manganese nano-chelate foliar application were significant for the most of plant traits at 1% probability level. Water deficit stress reduced all of the studied traits except carotenoid pigment content and proline. Also chlorophyll content and carotenoid were increased by foliar application of iron and manganese nano-chelate at both vegetative and reproductive stages. Finally, interaction between two main treatments were significant for the most of the traits at 1% probability level.
