Abstract:
To evaluate the effect of foliar application of nano iron and zinc chelated fertilizer on yield and agronomic characteristics of canola (Brassica napus L.) cv Hyola 308 hybrid under drought stress an experiment was conducted in a randomized complete block design with three replications in Ramhormoz, Khuzestan province in 2012 growing season. Main plots consisted of three levels of irrigation: irrigation in the whole the growing season (control), irrigation cut at the green bud stage and irrigation cut at the seed formation stage and foliar application treatment at the beginning of stem elongation and flowering as subplots consisted of four levels: sprayed with water(control), foliar application with Nano-zinc, foliar application with nano-iron, foliar application composition with nano-zinc and nano-iron (each of them was a concentration of two per thousand). The results showed that cut irrigation in reproductive growth stage decreased the grain yield (18 percent), biological yield (6 percent) and harvest index (14 percent). Plant height and the weight of one thousand seeds were influenced by the interaction of irrigation and spray. Most of the seed oil content (45.2 percent), the weight of one thousand seeds (4.13 g) and plant height (106.5 cm) were related to the irrigation treatment in whole growth stages and foliar application of nano iron and zinc chelate combination. Spraying plants with nano chelate iron and zinc improved plant tolerance and increased yield in drought stress condition in relation to spray by water (control).
