Interactive Effects of Salinity Stress and Zn Availability on Physiological Properties,Antioxidant Activity,and Micronutrients Content of Wheat (Triticum aestivum) Plants     

Amir Hossein Saeidnejad  Mohammad Kafi  Mohammad Pessarakli 《Communications in Soil Science and Plant Analysis》2016,47(8):1048-1057

In order to evaluate the combined effects of salinity stress and Zinc (Zn) applications on wheat growth, an experiment was conducted with the treatments included four Zn levels (0, 10, 20, and 40 mg/kg of dried soil) and three levels of sodium chloride (NaCl) salinity of irrigation water (0, 100, and 200 mM NaCl). Salinity caused a significant reduction in chlorophyll a and b content. The activity of catalase (CAT), superoxide dismutase (SOD), and glutathione reductase (GR) was enhanced as salinity level was increased. The significant enhancement in concentration of sodium due to the salinity was alleviated by Zn addition. Potassium content was increased by Zn treatments. A substantial increase was observed in leaf Zn concentration as the applied level of Zn was increased. Overall, these results indicate some positive and negative interactions of salinity and Zn application, which could be helpful in management of the saline soil and water.  相似文献   

Lentil Response to Nitrogen Application and Rhizobia Inoculation     

Jinwen Huang  Reza Keshavarz Afshar 《Communications in Soil Science and Plant Analysis》2016,47(21):2458-2464

Lentils (Lens culinaris L.) are an important component of the dryland farming systems in the western USA. Optimum nitrogen (N) management can enhance yield and quality of lentils. We conducted a field (at two locations, one with previous history of lentil and the other one without lentil history) and a greenhouse study to evaluate response of lentil to the application of rhizobium inoculant and starter N (control, 22 kg N ha^?1 in the form of urea [U], 22 kg N ha^?1 in the form of slow-release or environmentally safe nitrogen [ESN], and 22 kg N ha^?1 U + 22 kg N ha^?1 ESN). In both, the field and the laboratory studies, lentil yield did not respond positively to the experimental treatments. Lentil average yield was 1216 and 1420 kg ha^?1 at the field condition. In this rain-fed system, lentil yield was mainly limited by moisture availability, and the application of an external N did not contribute to the yield enhancement. Both of these treatments, however, increased protein content. Compared to the control, the application of rhizobium plus U and ESN enhanced protein content by about 34% (from 23.1 to 30.9%). The application of U+ESN also considerably increased postharvest residual nitrate (NO₃)-N in the soil, which can be easily leached and creates environmental pollution. Briefly, the application of U+ESN increases lentil protein content, but more efforts are needed to optimize N management in lentils in order to reduce the environmental concerns in the shallow soil.  相似文献

Effect of nitrogen and wheat residue on cotton (Gossypium hirsutum L.) yield and weed control     

Seyed Abdolreza Kazemeini  Reza Moradi Talebbeigi  Mohsen Valizade 《Archives of Agronomy and Soil Science》2016,62(3):395-412

Wheat (Triticum aestivum L.) residues and nitrogen (N) management are the major problems in the southern part of Iran where irrigated wheat–cotton (Gossypium hirsutum L.)–wheat rotation is a common practice. A 2-year (2009–2011) field experiment was conducted as a split plot design with four replications at a cotton field (Darab), Fars Province, Iran, to determine the influence of different rates of wheat residue (0%, 25%, 50%, and 75%) incorporation and N rates (150, 200, 300, and 400 kg ha^?1) on weed suppression, yield, and yield components of cotton. Results showed that a higher residue incorporation and a lower N rate improved weed suppression in both years. For treatments receiving 150 kg N ha^?1 and 75% of wheat residues (2250 kg ha^?1), weed biomass and density were significantly lower compared to treatments receiving 400 kg N ha^?1. The highest cotton lint yield (about 2400–2700 kg ha^?1) was obtained by 300 kg N ha^?1 in the absence of residue application, in both years. Incorporation of 25% of wheat residue (750 kg ha^?1) and application of 300 kg N ha^?1 are recommended to guarantee an optimum level of cotton lint yield and weed suppression in a wheat–cotton–wheat rotation in this region.  相似文献   

Effects of types of nitrogenous fertilizer (biological,chemical, integrative) and cropping mixes on some forage-medicine characteristics in additive intercropping of sorghum (Sorghum bicolor [L.] Moench) with fenugreek (Trigonella foenum-graecum L.)     

Hamid Abbasdokht  Mohammad Reza Chaichi  Sadegh Asadi  Mehran Manafi Noran  Hamid Reza Khademi 《Archives of Agronomy and Soil Science》2016,62(12):1741-1752

In order to investigate the effects of nitrogenous fertilizers (biological, chemical, integrative) on quantity and quality of forage-medicine in the additive intercropping of sorghum with fenugreek, an experiment was performed in two agronomic years 2010–2011 and 2011–2012 in the Research Farm of Agricultural Faculty of Tehran University located in Dolatabad, Karaj, as split-plot in the form of randomized complete block design (RCBD) with three replications. The main treatments consisted of the control or without fertilizer (N0), biofertilizer (Nbi) (Azotobacter, Rhizobium, Azospirillum, mycorrhiza), chemical nitrogen fertilizer (Nch 100) and integrative fertilizer including biofertilizer plus 50% chemical nitrogen fertilizer (Nbi + Nch50). The subtreatments included sole cultivation of fenugreek without weeds (T0), sole cultivation of fenugreek with weeds (Tw), sole cultivation of sorghum without weeds (S0), sole cultivation of sorghum with weeds (Sw), cultivation of sorghum + 50% fenugreek (ST50) and cultivation of sorghum + 100% fenugreek (ST100). Based on the results, the highest effective extract of fenugreek (trigonelline) and fenugreek dry matter was gained through the application of biological fertilizer + the sole fenugreek treatment (no weeds). Moreover, the highest sorghum dry mater was yielded by the use of the integrative fertilizer + the sole sorghum (no weeds) treatment; however, the highest total dry matter was observed to be more in the mixed treatment of integrative fertilizer and sorghum + 50% fenugreek. The lowest weed biomass was also linked to the integrative treatment biological fertilizer and sorghum + 100% fenugreek.  相似文献   

An analytical approach for the recovery behavior of cut pile carpet after static loading by mechanical models     

Sahar Jafari  Mohammad Ghane 《Fibers and Polymers》2016,17(4):651-655

In this paper, a viscoelastic model for the recovery behavior of the machine-made carpet has been presented. Different combinations of spring and dashpot systems are usually considered to model the mechanical behavior of textile materials. The initial thickness of the carpet samples was measured using a digital thickness gauge. The samples were then imposed to static loading. Consequently, the thickness of carpet samples after the load removal was measured again by considering the relaxation time at the range of 1 to 30 minutes with the intervals of 2 minutes. Jeffery’s mechanical model, which is combined of spring and dashpot components, was used to model the variation trend of thickness loss percentages for the carpet samples at different relaxation times. Curve fitting based on the least square method was used to adapt the experimental data to the theoretical model. For comparison, the standard linear model was also applied to experimental data. The results showed that there was a reasonably good agreement between the Jeffrey’s model and the experimental data. The results also revealed the linear standard model showed poor regression for the recovery properties of cut pile carpets after static loading. The reason was that the standard linear model was completely elastic, showing no secondary creep. On the other hand, the recovery of cut pile carpers showed some permanent creep that could be explained by Jeffrey’s model.  相似文献
