Abstract

In order to study the effects of foliar micronutrient application on growth and yield of wheat, a field experimental was carried out in a randomized complete block design with four replications at agricultural research station of Delgan city, Sistan Province, Iran during 2010 growing season. Different treatments of micronutrient foliar including, F1=Fe 2.5 lit/1000 form Iron sulphate, F2= Zn 2.5 lit/1000 form Zinc sulphate, F3= Mn 2.5 lit/1000 form Mn sulphate, F4= Fe+Mn 1.5 lit/1000, F5= Zn+Mn 1.5 lit/1000, F6= Fe+Zn 1.5 lit/1000, F7= Fe+Zn+Mn 1lit/1000, F8= Fe 4 lit/1000 form Iron sulphate and F9= control were applied. The results showed that micronutrient application significantly affected plant height, number of spike per plant, number of grain per spike, 1000-grain weight, grain yield, biological yield and harvest index. Application of Mn+Fe had the highest positive effect on yield components and grain yield. The combination of Zn+ Fe+Mn and control gave the lowest values of most studied traits. It could be concluded that micronutrient application had positive effect on wheat growth and yield.

Abstract

A field and a laboratory experiments were conducted in 2008 to determine the effect of irrigation treatments on yield, yield components and seed germination of foxtail millet (Setaria italica). Conventional furrow irrigation (M1) and alternate furrow irrigation (M2) methods and different deficit irrigation levels including 100, 85, 70 and 55% of crop water requirement (V1, V2, V3 and V4) made the treatments. Seeds of the field experiment were used for the laboratory experiment. In the laboratory experiment, germination traits of seed produced from maternal plant under irrigation treatments were tested. Results showed that irrigation treatments had a significant effect on peduncle length, leaf and stem weight, panicle weight, seed yield, biological yield and seed germination rate. M1V1 had higher seed yield than M2V3 and M1V4. M2V4 had the lowest seed germination rate except compared to M1V3 and M1V2. Overall, it is concluded that water stress and irrigation methods had minor effect on seed yield, yield components and seed germination. It was found that foxtail millet was drought-resistant.

Abstract

The existence of the glacier forms represents the function of the glaciers in development and evolution of the earth surface. Gahar Lake in Iran is one part of the old and cold climate heritage still existing in today warm and half-dry climate of Iran. This lake is located in the southern slope of Oshtorankuh in a fault valley having the area of about 88 hectares: its height is 2355m, its maximum depth 28 m, and its circumference 5245m. Previous researches claim that the formation of this lake was due to the landslide. This is the question of this research; what is the effect of the process of glacier sediments in formation of this lake? This research has been done by using field study, the study of mass deformation of shapes, and by using ETM sensor images, aerial photos, topography and geological maps. The results show that moraines Sholila and Ghiff Glacier valleys have caused the formation of the Gahar Lake. They have done this by moving and locating against the flowing of the Gahar River. The spectral reflection of the blocking sediments of the lake corresponds to the sample sediments of moraine present in the center of Sholila and Ghif circuses. Therefore, the lake has been formed due to the movement and situating of the glacier sediments. So it is considered as the heritage of cold climate of Iran, and tectonic and sliding origin of its formation proves invalid.

Abstract

To evaluate effects of seed priming with potassium nitrate on germination and emergence traits of two soybean cultivars in salinity stress, two laboratorial and greenhouse experiments were carried out as a factorial experiment based on a completely randomized design with 4 replications in the Seed Physiology Research Department of Agricultural Faculty of Bu-Ali Sina university, Iran. Treatments were included of two soybean cultivars (Sahar and Gorgan-3), two levels of non-priming and priming with potassium nitrate at 6 g l -1 concentration and three levels of salinity (0, 4 and 8 ds m -1 induced by sodium chloride). The results showed that Sahar cv. was superior to Gorgan-3 cv. in all traits and in both experiments. Seed priming with Kno3 caused a significant increase in germination and emergence percentage, radicle and plumule length, seedling dry weight, plant height, plant leaf area and plant dry weight. Also at the salinity stress, mean germination and emergence time of primed seeds were less than non-primed seeds, significantly. At the salinity stress, specific highest salinity level, final germination percentage, radicle and plumule length, plant height, plant leaf area and plant dry weight of primed seeds were more than non-primed seeds, significantly. Positive effects of priming with potassium nitrate on seeds of Gorgan-3 cv. were greater than those of Sahar cv.

Abstract

To evaluate effect of irrigation disruption on the harvest index of flower and essential oil of Calendula officinalis L., an experiment was conducted as split plot at the Research Farm of Faculty of Agriculture, Urmia University (latitude 37.53 °N, 45.08 °E, and 1320 m above sea level) in 2010. Treatments included end season water deficit (irrigation disruption at first, second, third harvest and without disruption as control) as main plot and amount of biological nitrogen (0, 3, 6, and 9 liter per hectare of biological nitrogen included Azotobacter and Azospirillum sp.) as sub plot were arranged in randomized complete block design with three replications. Data analysis of variance showed the significant interaction effect between irrigation disruption and biological nitrogen on essential oil and flower harvest index in first harvest, second harvest, third harvest, fourth harvest, fifth harvest and sum of total harvest. The highest harvest index of essential oil (0.38 %) in sum of total harvest belonged to irrigation disruption after first harvest and 9 liter per hectare of biological nitrogen. The maximum flower harvest index in in sum of total harvest (11.8 %) was obtained from control treatment of irrigation (without irrigation disruption) and 9 liter per hectare of biological nitrogen.

Abstract

Fifty one spring genotypes with three check cultivars were evaluated under two post anthesis drought stress 40% (E1) and 70% (E2) and 100(E3) Water Field Capacity in GHARAKHYL station green house. Trial carried out using augmented design with three blocks that checks were replicated to block uniformity in 2009-2010. Five drought tolerance indices comprising: Stress tolerance index (STI), Tolerance (TOL), Stress susceptibility index (SSI), Mean productivity (MP), and Geometric mean productivity (GMP) were used to genotypes response in three environments. Tolerance indices had different linear regression to Ys respectively. STI and GMP in E1 and STI, TOL, MP and GMP in E2 had significant linear relationships to Ys. Analysis of variance showed that there was a significant genetic variation among genotypes for all criteria. There were significant correlations of YE3 with MP, GMP, STI, TOL, SSI, STI and YE1 with (GMP and STI) under both environments and could be conducted for high GMP and STI. Cluster analysis of genotypes by using of YE1, YE2, YE3 and five other indices categorized genotypes into four groups each of which having 27, 11, 16 members and 3 in E1 and 28, 8, 18 and 3 members in E2. Cluster analysis distinguished groups contains superior lines for both E1 and E2, considering their yield performance (YE3 and YE1& E2). In E1 and E2 tolerance and high yield were settled in Cluster 2 and Cluster 4 respectively.

Abstract

Two pot experiments were designed to investigate above- and belowground interactions and plant density effect on wheat and wild oat performance. Theses experiments were conducted as factorial based on randomized complete design with four replications. The treatments of first experiment included four interference level (above-ground, below-ground, full and no interaction of wheat and wild oat) and four wild Oat densities (2,4,6 and 8 plant/pot) and for second experiment were four densities of wheat and Avena fatua (0, 2, 5 and 8 plants per pot). In both plants, full and belowground interaction decreased plant height, number of leaves, flag leaf area, chlorophyll content of flag leaf, biomass and grain yield compared to aboveground interaction and control, significantly. All traits of wild oat reduced by aboveground interaction compared to control. In full interaction, flag leaf chlorophyll content of wheat and wild oat were reduced about 10.7% and 6.9% compared to control, respectively. Number of leaves, biomass and grain yield of wheat and wild oat showed greatest susceptibility to interaction treatments. When wild Oat density increased the biomass, grain yield, plant height, number of leaves, flag leaf area, chlorophyll content of flag leaf of wheat decreased. Increasing of wheat density reduced root volume, root dry weight, grain and biological yield and 100 seed weight of Avena fatua, significantly. Maximum grain yield, biological yield, 100 seed weight, root dry weight and root volume loss of A. fatua were 78.22%, 67.11%, 41.90%, 52.82% and 43.75% compared with the control, respectively.

Abstract

Soil hydraulic properties including soil water characteristics curve and hydraulic conductivity are two important properties to determination of water movement in soil. The aim of this study was to evaluation of fitting quality of Mualem-Van Genuchten model on moisture curve and comparing in two soil texture classes (sandy loam and clay loam) and in different compaction treatments. Samples were collected from 0-10cm depth and Compaction created by proctor in six replication and four levels including C0 (control), C1, C2 and C3 by increasing in soil bulk density with the ratio of 5, 10 and 15%, respectively. Mualem-Van Genuchten model using RETC software were fitted on moisture-suction data obtained from pressure plate. Fitting quality of considered model achieved by R2 and RMSE calculation. RMSE in sandy loam soil had no change compared to control. But clay loam soil had increasing trend in terms of RMSE. Due to little changes of model in sandy loam in all treatments compared to clay loam, the use of this model in light textured and field compaction status was recommended.

Abstract

In order to investigate the likely allelopathic potential of an aqueous extract and powder of lemon balm (Melissa officinalis) on the germination and seedling growth of pea (Cicer arietinum), safflower (Carthamus tinctorius L.) and wheat (Triticum sativum), an experiment was carried out at the laboratory and greenhouse of agriculture faculty of Shahid Bahonar University of Kerman, Iran, from October 2009 to March 2010. A completely randomized design with three replicates using five extract concentrations of lemon balm plant including 0, 25, 50, 75, and 100 g l-1 and four amounts of lemon balm powder including 0, 7.5, 15 and 30 g 2kg-1 of soil was employed in laboratory and greenhouse experiments respectively. All extract concentrations of lemon balm except 25 g l-1 inhibited pea and wheat seed germination significantly, but had no inhibitory effect on germination of safflower. The powder of mature lemon balm plants affected the fresh and dry weight and shoots elongation in these crops negatively compared with the control in all levels. Therefore use of this plant should be prevented in rotation or intercropping with these three crop plants. Further research conducted in the analytical laboratory as well as in the field is needed before a practical application of the extract and powder as weed inhibiting agent can be recommended.
