to determine sugar content and root yield variation of new sugar beet hybrids under different irrigation levels, an experiment was carried out at zarghan agricultural research station offars agricultural and natural resources research center, shiraz, iran. the study was conducted as split block based on a randomized complete block design with three replications for two years, 2009-10, using lin...

Supplementary irrigation moderates the damage caused by drought stress in rainfed agriculture. Meanwhile, the application of nano fertilizers and methanol as the foliar application can be considered as effective management strategies to improve production under dryland conditions. For this purpose, the effect of supplementary irrigation, nano fertilizer spraying, and methanol foliar spraying wa...

In order to investigate the changes in fatty acids composition of rapeseed lines under Chitosan application, a factorial split-plot experiment was conducted based on RCBD in 3 replications during 2 years (2014-2016) in Karaj, Iran. Irrigation and Chitosan as main plots and cultivar in sub-plots were considered. In this study, treatmen...

Irrigation is widely criticised as a profligate and wasteful user of water, especially in watershort areas. Improvements to irrigation management are proposed as a way of increasing agricultural production and reducing the demand for water. The terminology for this debate is often flawed, failing to clarify the actual disposition of water used in irrigation into evaporation, transpiration, and ...

 In order to study the effects of bio fertilizers application on quantitative and qualitative yield, proline content and activity of some antioxidant enzymes in sunflower (Helianthus annus L.  var.  Urofelor) in different irrigation withholding levels, a factorial experiment was conducted based on randomized complete block design with three replications in research farm of faculty of Agricultur...

OBJECTIVE Evidence surrounding systemic absorption of gentamicin during intraoperative irrigation of the paranasal sinuses is lacking. The objectives of this study were to determine (1) if topical gentamicin is absorbed from the paranasal sinuses, (2) if hearing loss occurs following topical administration of gentamicin, and (3) if gentamicin placed within the sinuses travels retrograde (agains...

In order to investigate the effect of zeolite on growth indices, yield and grain yield components and protein of lentil in dryland and supplementary irrigation conditions, a field study was conducted in Shahrekord University, Shahrekord, Iran. The experiment was performed as a split plot in a randomized complete block design with three replications. The main factor included three levels of irri...
