Considering the importance of cotton in crop rotation and the decreasing trend of its cultivation area in recent years, it is necessary to use efficient and optimized methods to increase the cultivation area and the amount of production of this strategic crop and to reduce its production costs. One of these methods is the delayed cotton cultivation of premature cultivars in the form of transplanting. Considering the important role of time management and irrigation in cotton cultivation, it is necessary to determine the optimal amount of water consumed by this plant in the delayed cultivation method. This research was carried out in a split plot design by randomized complete block design with three replications. Irrigation interval treatments (including irrigation after 70, 105 and 140 mm cumulative evaporation from the evaporation pan) as main plots and different irrigation water amounts (including 50, 75, 100 and 125% of evaporated water from the pan) as subplots were considered. The results showed that the treatment of irrigation after 105 mm evaporation from the pan had the highest yield, bolting percentage, water use efficiency and lint content, and yielded higher yields of 11 and 40% than 70 and 140 mm treatments, respectively. While 100% water treatment with 2016 kg/ha had the highest yield among irrigation depth treatments, the difference between treatments with 50 and 125% was not significant in 5% level in Duncan test. On the other hand, with increasing water depth, water use efficiency decreased, in such a way that 50% water treatment had the highest water use efficiency. Finally, according to the evaluation results of performance, yield components, and water use efficiency, the best treatment was irrigating after 105 mm evaporation from the pan with depth of 50%.

This study was carried out during two years (2009 and 2010) at the Agriculture and Natural Resources Research Station of Ardabil, Iran. In this study, 12 early growing (Marfona, Sinora, Fontane, Oshina and Natasha), moderately late growing (Satina, Markies and Arcona) and late growing (Luta, Agria, Savalan and Caesar) potato cultivars were arranged in randomized complete block design with three replicates in two separate experiments (spring planting and planting after harvesting barley). Analysis of variance of traits measured showed that three were significant difference between planting types, among cultivars and their interaction in both total and marketable tuber yields, tuber number and weight per plant; interaction between year×planting types, cultivars× planting types, year×cultivar and year×cultivar× planting type, average tubers size and among cultivars for plant height and main stem number per plant. Luta, Markies and Fontane cultivars had high total and marketable tuber yields and tuber weight per plant in spring planting, Arcona, Markies, Marfona and Luta cultivars in after barley harvest planting during 2009, Agria, Luta, Savalan and Caesar cultivars in spring planting and Luta, Savalan and Agria cultivars in after barley harvest planting during 2010. Relationship between total tuber yield with marketable tuber yield, tuber number and weight per plant and tuber size average were significant and positive. Tuber weight per plant had the most direct positive effect on the total tuber yield. It was also found that Savalan, Luta, Satina, Markies and Fontane (late and moderately late growing types) as high yielder and stable cultivars; Agria (moderately late growing) were to be as high yielder but unstable cultivars; Caesar (late growing type) as low yield but stable cultivar and Sinora, Oshina, Arcona, Natasha and Marfona as low yielder but unstable cultivars.

There are numerous factors that contribute to the realization of a successful cotton crop. Two major management decisions, variety selection and planting date management can have a profound effect on the development and final outcome of the crop. In order to study the yield and correlation between traits of cotton cultivars in Moghan region with two planting dates, spring (May 15) and summer (June 21), an experiment was conducted on ten cotton cultivars (Avangard, Mehr, Crema, Sp-731, Sp-732, 001, No. 210, JR-3, No. 228, No. 200) as a randomized complete blocks design with three replications in 2013-2014 cropping year at Ardebil Agricultural Research Center (Moghan). In these experiments various traits of cotton cultivars (yields of first cutting, second cutting, total cutting, total yield, plant height, number of bolls per plant, and prematurity and green percent) were investigated in two spring and summer planting dates. The results showed that, all traits, except plant height were affected by planting dates. The interaction between planting dates and cultivars was significant for all traits, except plant height and second harvesting. The highest yield of first and second harvesting were obtained by Mehr, Avangard, SP-731, SP-732, NO. 210 × spring planting and Mehr, Avangard, Sp-731, Sp-732 × summer planting, respectively. The lowest yield of these tow traits were obtained by Crema, Sp-731, No. 200, No. 228, JR-3, No. 210, No. 001 × summer planting. The highest total yield, Balls number and prematurity percentage, were obtained by SP-732, NO. 001, Mehr, SP-731, NO. 001 × spring planting, jointly. Also the lowest of these traits were obtained by NO. 210, NO. 200, and SP-731 × summer planting, respectively. The highest and lowest of plant height were achieved in NO. 001 × spring planting and SP-732 × summer planting, respectively. Among ten cotton cultivars, the highest yield belonged to SP-731, Avangard and SP-732.

The viability, height, and vitality of Persian oak (Quercus brantii) seedlings from five different seeding techniques were studied in a completely randomized design. The treatments included 1) seeding in holes with 50 cm depth and 40 cm diameter in the shelter of 50% UV resistant laces (shade treatment), 2) seeding in holes with 50 cm depth and 40 cm diameter and pouring down hummus and litters on sown seeds (litter treatment), 3) seeding in holes with 50 cm depth and 40 cm diameter and use of super-absorbent (super absorbent treatment), 4) seeding in holes with depth of 100 cm and a diameter of 60 cm (deep hole treatment), and finally 5) seeding at a depth of 5 cm from the soil surface (control treatment). Also, the relative light intensity in all holes was measured using a fisheye camera, and a regression model was obtained from the seeding survival rate. The results of the comparison of the mean (p <0. 01) indicated that the deep hole, super absorbent, shelter, and litter treatments showed a 134. 5, 138. 2, 178. 6, and 243. 3% increase in seedling viability, respectively. Furthermore, shelter and deep holes treatments revealed a 19. 5% and 31% increase in seedling height, while litter and deep holes treatments had 18% and 31% increase of seeding vitality, respectively. The fitted regression model indicated a significant correlation (R2 = 0. 73, p <0. 01) between viability and relative light percentage (except for the deep hole treatment). Results revealed that litter treatment can be recommended as the most suitable method for the oak seedling. However, further research is required in case of the shade and deep holes treatment, which showed the best survival performance prior to soil erosion and seedings mortality.

Introduction: The most common cause of short delayed arousal is due to “overdose of a sedative-hypnotic” medication after general anesthesia and it is not of clinical importace. However, long term delayed arousal is due to several important conditions that can confuse anesthesiologists.Case report: The patient was a 28 years old woman with mucormycosis, candidate for sinuses drainage by endoscopic intervention .One months before surgery, while she was in 18-19 weeks of gestational age, she suddenly felt dyspnea and fatigue. In further investigations, severe anemia was diagnosed and in bone marrow biopsy AML-M5 was detected. Physicians decided to end her pregnancy by D&C. After one week of chemotherapy with Cytosar (Cytarabine) and Idarubicin, pneumonia and sepsis occured. Therapy with Vancomycin and Amphotericin B and Imipenem leads to epistaxis and rhinorrhea. CT Scan of sinuses demonstrated mucormycosis. She was alert and awake before general anesthesia with Fentanyl and Cisatracurium and Propofol for induction and maintenance. At the end of operation she could not be awake .Her delayed arousal had been continued for one day, then awakened spontaneously and discharged from hospital.Conclusion: Several factors such as chemotherapy drugs (affects on liver and brain),length of operation, imbalance in levels of electrolytes and low proteins due to malnutrition caused by cancers are the possible causes of the condition. Use of BIS maybe a good offer to decrease anesthetic drug doses during general anesthesia.
