comparison the effects of spraying different amounts of nano zincoxide and zinc oxide on, wheat

in order to compare the effects of different spraying of nano zinc oxide and zinc oxide, the arable irrigated wheat was conducted in two separate trials in 2011-2014 lands of abadeh city.experiments were conducted in a randomized complete block design, with five treatments and five replications.in the first experiment, treatments included the application of nano zinc oxide to five levels ( 0 , 24 , 36 , 48 and 60 g ha ) and fertilizer treatments including zinc oxide in a second experiment at five levels ( 0 , 24 , 36 , 48 , 60 g ha ) applied to five replications. it should be noted that nano-compounds are quickly absorbed by plants in large amounts it can be toxic effects on plants and plant products, consumers can . it would have been chosen according to the amount nano oxide. data were analyzed statistically using the software mstat-c and means were compared using duncan multiple range test was used. maximum yield rate of 95/401 grams per square meter of treated nano zinc oxide 60 g ha and the lowest yield rate 28/267 grams per square meter to the control treatments without foliar zinc oxide was obtained
