  Codling moth, Cydiapomonell, is the key pest of apple orchards at Khanehzenyan, Shiraz, Fars, Iran. To determine the best application time of spraying via counting the number of trapped moths and recording the effective daily temperature during 2009-2011, pheromone trap More

  Codling moth, Cydiapomonell, is the key pest of apple orchards at Khanehzenyan, Shiraz, Fars, Iran. To determine the best application time of spraying via counting the number of trapped moths and recording the effective daily temperature during 2009-2011, pheromone traps used at the height of 1.5 m from the ground level with distance between traps of 85-100 m. The data was analyzed using Excel software. According to the results, the number of pest generations and spraying time were determined. The results indicated that C. pomonella had two complete and one partial or incomplete generation at Khanezenyan.The best time for chemical control of C. pomonella was coincidentwith the time of appearance of the first age larva and accumulation of 175 degree-days. The required sums of temperatures for completion of one generation of C. pomonellawere 766.5 and 770 degree-days for the years 2009 and 2011 respectively.Therefore, by this way we can reduce the irregular uses of chemical pesticides and environmental pollutions.   Manuscript profile

  This experiment was conducted in in Boin Zahra area, Qazvin at 2015-2016 in order to investigate the effect of spraying time and micronutrient elements on wheat traits in split plot as randomized complete block design with three replications. The time of spraying at stemming stage and spike emergence stage as main factor and the micronutrient elements in 8 levels: non-consumption (pure water), iron, zinc, copper, iron + zinc, iron + copper, copper + zinc and iron + copper + Zinc in sub plots. The results of analysis of variance showed that the effect of spraying time (at 5% level), micronutrient elements (at 1% level), and the interaction effect of spraying time × micronutrient elements (at 1% level) on grain yield was significant. The results of comparison of the effect of spray time on grain yield showed that spraying during spike emergence increased grain yield. Spraying at the time of emergence of spike with an average of 6789 kg/ha was significantly superior to stemming stage, and increased by about 5%. The results of the comparison of micronutrient effects on grain yield showed that the coagulation of iron + copper + zinc with the mean of 7483 kg/ha had the highest grain yield. The results of comparing the effects of spraying time and micronutrient on grain yield showed that iron + copper + zinc solution had the highest grain yield at spike time. The results also showed that spray application spray increased seed yield of each micronutrient treatment. Manuscript profile

  Identifying the critical time and timing of plant irrigation based on a precise and basic plan is the key to water conservation, improvement of irrigation operations and plant tolerance to water shortage in agriculture. In recent years, vesicular arbuscular mycorrhizal fungi have been used in many plants to deal with dehydration and drought stress. In this regard, an experiment was conducted as split-plot in the form of randomized complete block design with 3 replications in the Yasuj region at years 2015 and 2016. Water stress was considered as the main factor in the form of irrigation after 30, 60, 90, 120 and 150 mm of evaporation from the evaporation pan class A and mycorrhizal fungus was considered as a secondary factor in the form of no application, application of Glomus mosseae and application of Glomus intraradices. The results showed that the interaction of irrigation and mycorrhizal fungi on flower phosphorus, flower yield, biological yield and water use efficiency of Borage was significant. In irrigation levels after 60, 90, 120 and 150 mm of water evaporation from the evaporation pan, the use of mycorrhizal fungi Glomus mosseae and Glomus intraradices compared to the absence of fungi respectively increased the yield of plant flowers (30.04% and 27.35 %), (90.2% and 90.98%), (93.21% and 94.1%) and (81.73% and 78.86%), also, at these levels of irrigation, biological yield and water use efficiency of Borage flower achieved a significant increase in the presence of mycorrhizal fungus, compared to the absence of mycorrhizal fungus application. Application of both strains of mycorrhizal fungus Glomus mosseae and Glomus intraradices in irrigation levels after 90, 120 and 150 mm of water evaporation from the evaporation pan compared to no application of mycorrhizal fungus, respectively, resulted in a significant increase in the harvest index of Borage flower (44.55% and 43.36%), (13.21% and 15.96%) and (5.6% and 5.41%) and flower phosphorus (44.69% and 20.45%), (150% and 125%) and ( 267.74% and 235.48%). Mycorrhizal fungus was able to moderate the negative effects of drought stress and increase the above-mentioned traits in those irrigation levels, and based on the results of this study, irrigation treatment after 90 mm of water evaporation from the evaporation pan + the use of Glomus mosseae mycorrhizal fungi is recommended.

  Aim of this research was evaluation of Chloro  Cholin Chloride (CCC) and  spraying time effects on physiological traits and activation of some atioxidant enzymes in corn (cv. 704) under drought stress. This research carried out using a split- split plot in based of a Randomized Complete Block Design with four replication in the research field of the Azad university in Karaj branch (Mahdasht) in 2007. Normal irrigation and drought stress (irrigation withhold after anthesis) allocated to main plots, treatments of spraying concentrations (0 and 1.5 Lit/ha) to sub plots and spraying time at (6 leaf stages and 15 days later on) to sub-sub plots. Results showed that drought stress effect on cytoplasm membrane stability, activity of Glutation oxidaze and  Super oxide dismotase (SOD) enzymes (p≤1%) and also  grain yield and Catalaze enzyme activity (p≤5%) was significant. The CCC application with concentration of 1.5 Lit/ha on yield and relative water content (RWC) (p≤5%) and antioxidant enzyme activity (p≤1%) was significant. Amount of  RWC for CCC treatments (65.5%) compared to the control (60.6%) showed significant differents.The grain yield for CCC treatments (10.7 ton/ha) was significantly higher than control (9.1 ton/ha). SOD activity for CCC (1740.5 mg. pico mol) was also significantly higher than the control (888.1 mg. pico mol). Manuscript profile
