The season of autumn and all of its elements and phenomenon is one of the vital subjects of nursery rhyme. In this article, the child poets approach and their inspiration in observing the visual attractions, natural and biological capabilities of autumn are pointed out; also the way of using the symbols and legends of autumn is discussed and explained. The results of the research show that some of the autumnal themed poetry that were created in the field of children’s poetry, were affective in creating an emotional-artistic connection; also at introducing the reader to the changes that are happening to the outside world with the arrival of the season. Based on the referred samples of the autumnal poems of nursery rhyme, can be broken down in four different approach categories: the classic, the cognitive, the pictorail and the general approach; and each one of these approaches have their own specific and special natures. The result of the ideology is the general and expressive style that the child poets are benefiting from it.

Purpose: The present research aimed at finding an answer to the question of the process of influence of cyberspace on Iranian poetry in the future, and the influence of cyberspace on various aspects of poetry such as content, its audience, the poet, the media that published the poem, the process of composing the poem, the rights of the author, and Globalization of the Iranian poetry. Method: The Delphi technique was used to carry out this research. A group of experts comprising professors in the fields of Communication and Literature was selected. The expert’s opinions were collected and analyzed through an in-depth interview, a questionnaire based on the Likert scale, and by the execution of three stages of Delphi rounds. Findings: Accordingly, considering the content, the experts predicted that due to the impact of cyberspace, the quality of the poetry will be reduced and consequently, the language of poetry will become simpler and close to prose and it will only reflect the daily events of life. Regarding the audience, they concluded that the audience’s selection power will be increased, however, we can differentiate between the public and professional audience. With respect to the sender, there will be no phenomenon of multi authors, and regarding the channel, the experts agreed upon Media Convergence besides, the poets’ agency in publishing their own poems will be increased. Conclusion: Experts believe that the spread of communication technologies will make censorship ineffective. This is the only case in which the group believes in the impact of technology on the future of poetry. The group of experts did not reach a consensus regarding the impact of technology on the phenomena such as publication of author’s poems as one’s original work and the Globalization of Iranian poetry, thus, analyzed these items in the framework of the human agency.

Seasonal and annual precipitation variations are subject to numerous natural and climatic factors such as climate teleconnection indices (CTIs). The purpose of this study is to investigate the correlation between CTIs and autumnal precipitation in 30 catchments of Iran. For this purpose, autumnal precipitation data were selected from 717 synoptic, climatological and rain gauge stations over a 28-year (1988– 2015) climate period, and their correlation with eight CTIs including SOI, MEI, NAO, AO, NCP, C-SST, M-SST, and P-SST were obtained in eight-time lags. Finally, their correlation significance were investigated and analyzed. The results showed a significant positive correlation between the MEI (29. 1% to 43. 3% of the western, southern, eastern and northeast watershed stations) and the NAO (29. 4% of the northwest basin stations), While the SOI (23. 3-53. 7 stations of the western, southern, eastern and northeast watersheds) and C-SST (23. 3 of the southeast watershed stations) had significant negative correlation. In terms of the time step, it was found that the Oct-MEI (43. 3% of the stations had a positive correlation) and Aug-SOI (53. 7% of the stations had a negative correlation) had a significant correlation with most of the studied stations. From the watershed point of view, it was found that the frequency of significant correlations in different catchments varied between 10. 9 and 36%. The results of this study show that about 10 watersheds have a significant correlation with more than 30% of CTIs which changes in each watershed. Consequently, the CTIs with different time steps can be used as predictor variables for autumn precipitation in Iran watersheds.

This experiment was conducted in the cultivation year 2007-2008 in the Agricultural Research Station of Isfahan. This experiment had a split-plot layout in the randomize complete block design whit three replication. Factors  included the cut of irrigation in seven stages (D1: normal irrigation or irrigation after 80mm evaporation from class A pan to physiological maturation as an check treatment (D2: Cut of irrigation in stem elongation stage (D3: cut of irrigation in flowering stages, (D4: cut of irrigation in pod production stages,(D5: deletion of irrigation from stem elongation to flowering stage, (D6: deletion of irrigation from stem elongation to pod production stages, (D7: deletion of irrigation from flowering to pod production stage) As main plots and  four Autumn Colza cultivars included Opera, Okapi, Zarfam and Modena as sub-plots. The results showed that the effect of cut irrigation on number of pod in the plant, number of seeds in the pod, the weight of 1000 seeds, grain yield, biological yield, harvest index and oil yield were significant P>0.01. According to the results, the most sensitive growth stage of autumnal colza to drought stress were first stem production stage and then flowering stage and finally the early of pod production. According to the obtained results cut of irrigation must be avoided during stem elongation, flowering and pod production but at the water deficient condition Cut of irrigation is more suitable at the end of pod production stage. Cultivar effects were significant, P>0.01, for the number of pod in the plant, number of seeds in the pod, biological yield, harvest index, grain yield and oil yield but the height of the plant and seed oil content were not significant.  Generally, Zarfam with highest weight for 1000 seeds and the most number of pod in plant produced the most grain yield.

Reliable prediction of dry and wet periods is an essential component in competent management of water resources. A more reliable prediction of the climate, pushes the public approach to these predictions further and lowers the disaster costs. Since the (ENSO)1 has recently been introduced as an important predictor for the anticipation of seasonal wet and dry conditions in Iran, the present study evaluates the significance level of such prediction for autumal and sixmonthly (October-march) precipitation using Fisher Exact test. Using the summer time (SOI)3 as the predictor, the significance of the occurrence of meteorological dry and wet conditions during following autumn is investigated. It has been shown that after a strong El, Nifio event in summer (SOI<-5), wet conditions are anticipated for most parts of the country at a 95% significance level. On the other hand, the prediction of dry conditions is not significant for such an event. It has found that the occurrence of normal rather than wet or dry conditions is significant for the eastern coasts of the Caspian Sea as the El Nifio is prevalence. During strong vigorous cold ENSO periods (SOI>5), the occurrence of autumnal dry conditions are significant for most of the studied stations at the 95% level. During such periods the prediction of wet conditions were found to be statistically meaningless for all parts of the country. It is shown that the occurrence of summer EI Nifio leads to the dominance of wet conditions in about half of the studied stations. The prevalence of summer La Nina does not however lead to the wide spread six-monthly drought.

In order to investigate the reaction of canola autumnal species to delayed cultivation, a research study was carried out in Karaj Research Institute of Modification and preparation of sapling and seed in 1385-86. The test was performed with factorial form of random complete block plan with three repetitions consistying of planting time in two levels (10 Mehr& 10 Aban) and numbers in five levels such as: Elite, Opera, SLM046, Orient and Okapi. Each land test consists of 6 lines with 4 meters length and 30 cm gaps. The space of plants is 5 cm that 2 side lines are margins.4 middle lines were contemplated for determination of phonologic plant stages and measurement of some properties such as: numbers of pods in plant, diameter of pods, numbers of pod in shrub, lengths of pod in shrub, number of seeds in pod shrub, weight of thousand seeds, yield of seed, percentage of oil in seed, yield of oil seed. It was observed that all testing properties were reduced in delayed cultivation except the percentage of oil in seed. Consequently, the yield of oil seed in delayed cultivation, that is economically important, showed a significantly reduction.

Conventional tillage systems have harmful effects on soil structure. To evaluate the performance of different methods of tillage on yield and growth characteristics of some autumn chickpea an experiment carried out in a randomized complete block design with 4 replications as split plot arrangement at the University of Tehran experimental farm in Karaj in 2012. In this study the effect of three conventional tillage, minimum tillage and no tillage were investigated on three chickpea cultivars yield included Arman, Hashem and ILC-482. Coincides with the planting of seeds, superphosphate fertilizer was added to the soil at the rate of 150 kg.h-1. The results of this study showed that the highest emergence percentage was related to conventional tillage, but since the pea plant is indeterminate, increasing the yield component like seeds per pod, number of pods per plant and seed weight in Hashem and Arman cultivars, led to better performance in minimum tillage compared with conventional tillage and no-till. Hashem and Arman cultivars hade the highest yield in tillage systems compared to other treatments.

In order to investigate the effect water stress on four cultivar of rapeseeds (Brassica napus L.), we did an experiment in research field of agriculture faculty of shahed university as split plot with use of randomized complete block design with three replications. The whole factor was including of three level of irrigation (5, 10 and 15 days orderly) and sub-factor was four cultivars of autumnal rape seed (RGS, Okapi, Elite and Tallaie). Length plant, length inflorescence, leaf soggy weight, leaf arid weight, stem soggy weight, stem arid weight, leaf area index, pod per plant, 1000-grain weight, percent oil and protein was measured. Variance analysis of data showed that effect of irrigation treatments was significant (P=0.05) on leaf arid weight and effect of varieties treatments was significant (P=0.01) on length inflorescence, pod per plant and leaf area index (P=0.05); but interaction effect of irrigation and varieties was significant (P=0.01) on length inflorescence only. Means comparison showed that Elite variety has the highest length plant (100.16 cm) then Okapi, RGS and Tallaie. Elite variety was superior than other varieties from length inflorescence (44.10 cm) followed by Tallaie, Okapi and RGS, respectively. Also, Elite variety was superior than other varieties from pod per plant (24.65) followed by Okapi, RGS and Tallaie, respectively. Stem soggy weight indicated more correlation (r=0.867) with seed oil percent than other yield component. Also these varieties weren't significantly different (P=0.05) in seed oil percent.
