In order to find suitable cultivar and N-topdress rates in corn planted after wheat harvest, a field experiment was conducted in Isfahan University of Technology Experiment Farm located at Shervedan, Falavarjan in 1994. The experiment design was a split plot with a randomized complete block arrangement and four replications. Main plots were four N-topdress rates (0, 90, 180, and 270 kg/ha) and ...

Floating culture of lettuce is developing because of the increase in water use efficiency and chemical fertilizers. In order to assess replacement time of nutrient solution and concentration of replenishment solution on growth and yield of Butterhead lettuce, a factorial experiment was conducted through completely randomized design with three replications. Each experimental unit was a 60×...

Considering the increasing trend of saline land enhancement and lack of appropriate agricultural lands, identifying salt resistant plants such as fenugreek, which is an important medicinal plant, is important. To do so, a factorial experiment was conducted in the form of randomized complete blocks design with three replications on three fenugreek landraces (Yazd, Shiraz and Hendi) and five sali...

Guar (Cyamopsis tetragonoloba L.) is a tropical drought tolerant crop, potentially proper for arid areas. The objective of present survey was to evaluate the effect of different irrigation regimes and salicylic acid levels on morphological, physiological and seed yield of Guar. The present experiment was conducted as split plots based on randomized complete blocks design with four replications....

Appropriate selection of donor parent for breeding purposes needs sufficient knowledge about genetic diversity and germplasm classification. In order to investigation and classification of genetic diversity in 35 wheat (Triticum aestivum L.) genotypes, an experiment was conducted in University of Shahed based on randomized complete block design with 2 replications in 2009. In persent study 15 m...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

In order to study the effects of superabsorbent polymers and drought stress on some morphological characteristics of Rosmarinus officinalis, a pot experiment was conducted as factorial, based on completely randomized design with four replications, in which factors included four levels of drought stress (irrigation up to 100, 75, 50 and 25 percent of field capacity (FC) level, respectively) and ...
