Abstract

Research Aim: study of the effect of methanol and nano zinc oxide on grain yield and some agrophysiological traits 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 zinc oxide at four levels (no application or foliar application with water as control, 0.3, 0.6 and 0.9 gr/lit nano iron oxide) and application of methanol in four levels (foliar application with water as control, 10, 20 and 30 volume percent of methanol). Findings: Means comparison showed that both application nano zinc oxide and methanol at the highest level increased days till ear emergence (8%), days till maturity (6.8%), grain filling period (10%), plant height (47%), the number of grains per ear (61%), grain weight per ear (82%), grain yield (33%), harvest index (8%), ear length (66%), protein and zinc content of grain (62 and 14% respectively) in comparison with no application of nano zinc oxide and methanol. But the highest level from both application nano zinc oxide and methanol decreased electrical conductivity of flag leaf in ear emergence stage (37.6%) and grain filling stage (55%) in comparison with no application of nano zinc oxide and methanol. Application of zinc increased relative water content of flag leaf in leaf mergence and grain filling stages (17 and 11% respectively) in comparison with no application of it. Maximum of dry matter remobilization in grain and contribution of dry matter remobilization in grain (0.38 mg per plant and 36% respectively), remobilization from stem in grain and contribution of stem reseves to grain yield (26.5 mg per plant and 19% respectively) were obtained in no application of nano zinc oxide. Similar results were obtained in methanol application. Conclusion: It seems that in order to increasing of grain yield and some agronomic traits of wheat, can be suggested that be applied 0.9 gr/lit of Nano-Zinc oxide and foliar application of 30 volume percent of methanol.
