Abstract

Effect of different levels of water for the Lake urmia on some morphological and physiological traits of maize in greenhouse conditions, a factorial experiment in randomized complete block design with 7 replications. 4 levels of salinity in the soil for this study included (zero, 5, 10, 15 and 20 mg mose) and two types of irrigation water (Ordinary water and lake Urmia water with a salinity of 2 ds) was used. The results showed that soil salinity effects on leaf number and stem length were significant. Effect of salt concentration in water on stem length, chlorophyll b and total chlorophyll was significant. The interaction between salt water and a home on stem diameter, stem weight and length Tasl, leaf length, leaf width and leaf weight, and soluble sugar were significant. Mean comparisons showed that most compounds treated stem diameter, stem weight, leaf length, leaf width, leaf weight, length Tasl and sugar solution to the control (non-saline soil and water) and with increasing concentration of salts in the soil of their was reduced and the salinity level of 20 mg m mouse to reach the minimum amount.

Abstract

In this study we tested stereo-photogrammetry under field conditions to detect changes of soil surface roughness caused by rainfall upon two agricultural soils surfaces - a seedbed plot and a harrowed plot. Three rainstormswith intensities of 60, 80 and 80 mm/h, respectively,were simulated on two plots of 1m2area and DEMs were generated before and after each rainfall. Using, DEMs, Three groups of roughness indices were calculated for each situation: (1) random roughness (RR), reduced random roughness (RR_rd) and corrected random roughness (RR_cr), (2) Tortuosity (Tb) and (3) limiting elevation difference (LD) as well as limiting slope (LS). In addition, surface variograms were calculated to characterize the microtopography at the beginning and end of the rainfall experiment.A detailed analysis of the factors influencing the stereo-photogrammetry process and the calibration of the system showed the importance of a stable support bearing the two cameras as well as a calm weather condition. Moreover, the effect of the correlation window size to optimize the DEM quality should be considered. All investigated roughness indices decreased as a result of rainfall on both plots; especially,LD and RR_cr were negatively correlated to cumulative rainfall.However, due to some difficulties in estimating Tb, no statement on its usability for detection of roughness changes is made in this study. The analysis of surface variograms showed that the heterogeneity of soil surface can be decreased by rainfall, while spatial correlation can be increased.If some basic provisions are considered to guarantee the image quality, stereophotogrammetry is a promising method to detect soil surface roughness and its changes caused by rainfall.

Abstract

Wireworms are the larval stage of clickbeetles (Coleoptera: Elateridae). They are soil-dwelling pests which attack the germinated seeds and roots of seedlings which usually lead to plant death. More damage is observed in the fields used as pasture previously. False wireworms are larval stage of Alleculidae. Hosts for both wireworms are wheat, barley, canola, sunflower and melon in the east of Golestan province. In this study, soils infested to true wireworms of genus Agriotes and False wireworms of genus Omophlus were compared. Samples were collected from four regions Gonbad, Kalaleh, Maravehtappeh and Golidagh. These samples were collected from wheat fields, and also from Omophlus in sunflower fields at a depth of 0-30 cm. Although the two genus damage wheat and sunflower in some fields, but we have found more damage in wheat fields by Agriotes and in sunflower fields by Omophlus. Analysis of soil showed that because soil texture was light in all samples, no significant differences existed between soil type and soil infested to wireworms. In terms of the distribution of wireworms, they were observed in all heights of sampling regions.

Abstract

The accumulation of heavy metals in soil causes environmental pollutions and is considered as a serious threat to human's health. This study has been carried out with the purpose of studying the toxic effects of cadmium on the concentration changes of proline and potassium in the shoots of two commercial varieties of pinto beans (Talaash and local Khomein). Experimental treatments included three levels of cadmium [0 (control), 25 and 50 mg. kg-1) and three levels of potassium (Control, 157.6, 300 and 600 mg. kg-1) and two varieties of pinto beans (Talaash and local Khomein) were examined at four different times (14, 28, 42, and 56 days). The results revealed that the interaction effects of the cultivar and cadmium on the proline of the shoot became significant (P<0.05). The highest concentration of proline was observed in the treatment of cadmium control and also in 300 mg. kg-1 potassium treatment in local Khomein variety after 28 days. With increasing the concentration of cadmium in the soil, the concentration of this element increased in both of the cultivars and the highest concentration of cadmium in the shoot (18.48 mg. kg-1) was measured in the treatments of 50 mg. kg-1 cadmium and 300 mg. kg-1 potassium in Talaash variety after 56 days. In general, local Khomein variety showed more resistance against the toxicity of cadmium than Talaash variety.

Abstract

In order to study the effect of sowing date and the methods of sowing on quantity characteristics and essential oil content on Moldavian balm, an experiment was carried out in research field of agronomy factuality of Uremia university in 2011. This research was conducted as factorial based on randomized complete block design with four replications. The first factor was including four sowing dates (April 9, 19 and 9, 29 May) and the second factor was two sowing method (direct planting at main field and sowing in the nursery and then transplanting). The results of analysis of variance showed that sowing date had significant effect on quantity characteristics and essential oil content and yield. The method of sowing factor had significantly affected on essential oil content and all of quantity characteristics. Also, interaction effect between sowing date and sowing method in term of quantity characteristics and essential oil content was significant at the 0.05 probability level. Maximum biological yield and essential oil content were obtained from combination treatments namely first sowing date and transplanting method. However, compare means showed that this combination treatment had no significant difference with combination treatment of second sowing date and transplanting method.

Abstract

Level Set Method (LSM) and Snakes Method (SM) are two different procedures used in image processing to locate objects location and boundaries. Both of these methods have their own advantages and limitations. In this research, a new algorithm for image processing of the weak gradient features was developed to improve the overall image boundary detection system. This algorithm was based on the active contour model in conjunction with level set method to enhance the images detection approach. The algorithm presented a new technique to incorporate the advantages of both LSM and SM. First, different bands of satellite image from a region were extracted from the satellite scene and then by linear combination of these images, the obtained image was resulted enhanced image.After combination the bands of satellite image, the initial segmentation by LSM was transformed and used as an input for the SM and began its evolvement to the interested object boundary. The results showed that the algorithm can deal with low contrast images and features on them, demonstrates the segmentation accuracy under weak image boundaries, which responsible for lacking accuracy in image detecting techniques. Thus, better segmentation and boundary detecting for the satellite images were achieved and ability of the system to improve low contrast images and low gradient features increased and as a result, they can deal with over and under segmentation.

Abstract

The aerial parts of Lippa citriodora (Verbenaceae) were collected at the fullflowering stage and dried by three different drying methods (sun-drying, shade-drying and oven-drying at 60 °C). The essential oils of every treatment were obtained by hydro-distillation method using clevenger apparatus. The oils were analyzed by GC and GC–MS. The main constituents of the oils in shade method were Limonene (4.0%), 1,8-Cineole (1.92%), trans- ocimene (3.2%), Neral (23.5%), Geranial (34.2%), (E)-caryophyllene (3.2%), GermacreneD (5.5%), bicyclogermacrene (4.1%), (E)-Nerolidol (1.8%) and Caryophyllene oxide (2.4%). The analysis of variance showed that the different drying methods had a significant effect on the quantity of essential oil. Finally it could be concluded that shade and sun drying method is suitable for highest essential oil quantity and Neral and Geranial concentration.

Abstract

Agriculture ranks among the most dangerous industries. Farmers are at very high risk for incidents. Chemical products were used to alter life cycles of living pest organisms and improper handling of them is dangerous to involved people. However, acute poisoning during spraying operation is an important health problem among farm workers and operators, but there is a substantial lack of data and studies from Iran to investigate unsafe acts and conditions, poisoning prevalence and factors could be effective in fostering pesticide application safety. Data were collected on 110 rice farm households using surveys and field observations in Fars Province of southern Iran. Acute poisoning prevalence and unsafe acts and conditions affecting it were investigated. An unsafe composite score, translating unsafe acts and conditions into score was developed. Chi-square test was performed to assess the association of acute pesticide poisoning with pesticide applicators’ characteristics and their unsafe acts and conditions. This study revealed that 12.7% of pesticide applicators suffered acute pesticide poisoning. The results showed pesticide applicators acute poisoning can be traced to unsafe practices in handling pesticide, personal protective behaviors and equipment malfunction. This study also showed None of applicators had received safety instruction. Safety training on proper pesticide handling could minimize chemicals risk factors. This study revealed how urgently needed such training programs are.

Abstract

Winter triticale (XTriticosecale Wittmack) could be more widely grown as a forage, grain, or cover crop in the cropping systems, but research needed to establish best management practices is limited. This study was conducted to determine the amount of nitrogen (N) and potassium (K) fertilizers needed to optimize triticale productivity. Treatments were four levels of nitrogen, as N1=0, N2=115, N3=160, N4=200 kgN.ha–1 and four levels of potassium, as k1=0, k2=50, k3=70, k4=90 kg K2O.ha–1. The experiment was done as randomized complete block design with three replicaties at Research of Agricultural Science and Natural Resources, Yazd, Iran, during 2008. Results of this study indicate that the highest rate of grain yield for triticale (6.1 ton.ha–1) was obtained by application of 160 and 90 kg.ha-1 nitrogen and potassium, respectively. Application of different levels of Nitrogen affected grain protein of triticale significantly, however using different amount of potassium had not any effect on grain protein. The percentage of the grain protein was increased markedly up to 160 kgN.ha-1. Increasing in nitrogen level more than 160 kgN.ha-1 led to a partial increasing in grain protein.
