Abstract

Research Aim: study of the effect of humic and nano iron oxide on growth and grain yield of wheat under rain fed condition Research method: A factorial experiment was conducted based on randomized complete block design with three replications at the farm of khatonabad in Sarab city in 2018-919 years. Factors experiment were included foliar application nano iron oxide at four levels (no application or foliar application with water as control, 0.4, 0.8 and 1.2 gr/lit nano iron oxide) and application of humic acid in four levels (without humic acid or foliar application with water as control, foliar application 100, 200 and 400 mg/lit). Findings: Means comparison showed that both application nano iron oxide and humic acid at the highest level increased plant height (23%),1000 kernal weight (17%), relative water content in ear emergence and grain filling stages (48 and 72% respectively), in comparison with no application of nano iron oxide and humic acid. The highest level from application nano iron oxide increased days till ear emergence (2.8%), days till maturity (3.2%), grain yield (29%), ear length (16%), protein and iron content of grain (29 and 21% respectively) in comparison with no application of nano iron oxide and humic acid. But the highest level from application nano iron oxide decreased dry matter remobilization in grain (66%) , contribution of dry matter remobilization in grain yield (28%), dry matter remobilization from stem in grain (63%) ) in comparison with no application of it. Similar results were obtained in humic acid application. Conclusion: It seems that in order to increasing of grain yield and some agronomic traits of wheat, can be suggested that be applied 1.2 gr/lit of Nano-iron oxide and foliar application of 400 mg/lit humic acid .
