  In order to study the effects of different levels of irrigation, nitrogen and plant population on yield, yield components and reserved dry matter remobilization of seed corn (SC. 704 hybrid) a research was conducted at the experimental field in Khuzestan Natural Resources and Agricultural Science University in summer, 2004. This research was made based on three split-plot field experiments, R...

In order to evaluate the effect of drought stress and determine of effective traits on grain yield and estimate of genetic parameters, 18 mutant rice lines were studied in normal and drought stress conditions. The experiments were carried out separately using randomized complete block design with three replications during cropping season 2014-2015 at Iranian Rice Research Centers in North of Ir...

A two-year field experiment (2015–2016) was conducted as a split plot design with four replications at School of Agriculture, Shiraz University, Iran to investigate the influence of water stress (supplying 50, 70, and 100% of water requirement) and wheat residue rates (0, 25, and 50%) incorporated with soil on physiological traits and canned yield of sweet corn (Zea mays L. V. Saccharata). Net ...

In order to study the effect of bio-fertilizers  in decrease the effects of water stress on yield, yield components and oil percentage of Goldasht spring safflower cultivars (Carthamus tinctorius L.), an experiment on split plot in a randomized complete block design with three replications was carried out  in 2012 at the Agricultural Research Station of Islamic Azad University of Roude...

For identification of correlations and relations among different traits in bread wheat, 30 genotypes were investigated based on a split plot experiment in the form of randomized complete block design with three replications under normal and moisture stress conditions during the 2016-2017 crop season. The results of the analysis of variance showed that the effect of genotypes was significant for...

today, environment protection and safe crop production are very important. the management of soil elements by bio-fertilizers is considered as important point for sustainable agriculture. mode of action of fertilizers is very different in drought stress conditions. to evaluate biological fertilizers (agrohumic, nitroxin, superabsorbent and vermicompost) and compare them with current chemical fe...

Fenugreek (Trigonella foenum-graecum L.) is one of the oldest medicinal plants. In order to study water-stress effects on some morphological characteristics of fenugreek, an experiment was carried out in a strip plots based on randomized complete blocks design with three replicates, at Research Farm of Shahrekord University, Shahrekord, Iran, in 2010. The first factor was allocated to four wate...

The yield stress of magnetorheological ͑MR͒ fluids depends on the induced solid structure. Since thick columns have a yield stress much higher than a single-chain structure, we improve the yield stress of MR fluids by changing the fluid microstructure. Immediately after a magnetic field is applied, we compress the MR fluid along the field direction. Scanning electron microscopy images show that p...
