Abstract
In order to study the effects of nano iron oxide on yield, chlorophyll fluorescence indices and some physiological traits of wheat (Triticum aestivum L.) under rain fed and supplementary irrigation conditions, a factorial experiment was conducted based on randomized complete block design with three replications in Agricultural Research Station of Ardabil in 2016. Factors experiment were included irrigation levels (no irrigation as rain fed, supplementary irrigation at heading and booting stages), foliar application nano iron oxide in four levels (without nano iron oxide as control, application of 0.3, 0.6 and 0.9 g L -1 ). Means comparison showed that 0.9 g L -1 nano iron oxide application and supplementary irrigation at booting stage increased maximum fluorescence (F m ), variable fluorescence (F v ), chlorophyll content, nitrogen percentage, relative water content and grain yield compared to non-application of nano iron oxide under rain fed condition. Rain fed condition increased minimum fluorescence (F 0 ) and electrical conductivity. Foliar application of 0.9 g L -1 nano iron oxide and supplementary irrigation at booting stage increased grain yield 38.43% compared to no foliar application under rain fed condition.
