in order to study the interrelations of photosynthetic rate and surfaces and leaf proline content with yield and yield components of safflower under different irrigation regimes, a field experiment in a split plot arrangement under a ranomized complete block design with four replication was performed at lavark reasrch farm, isfahan university of technology, isfahan, iran in 2007. two irrigation...

in order to investigate the effect of domestic wastewater and normal water (well water) on soil chemical properties and alfalfa yield, a research project was conducted for three years in chahartakhteh research station. the experiment was performed in randomized complete blocks design including four treatments in three replications. treatments were as follows: t1: irrigation with normal water at...

Plant polyphenols have gained prominence in quality of plant products and in human health. An experiment was conducted to determine the association of tea polyphenols with water stress and their suitability as indicators for drought tolerance. The experiment was conducted in a 'rain-out' shelter, and consisted of six tea clones (BBK 35, TRFK 6/8, TRFK 76/1, TRFK 395/2, TRFK 31/30, and TRFK 311/...

introduction: maintaining soil moisture content at about field capacity and reducing water loss in near root zone plays a key role for developing soil and water management programs. clay pot or porous pipe is a traditional sub-irrigation method and is ideal for many farms in the world’s dry land with small and medium sized farms and gardens and is still used limitedly in dry lands of india, ira...

this study was conducted to determine soil properties that correlate with the arbuscular mycorrhizal fungal (amf) spore numbers in semiarid calcareous soils of hamadan province in northwestern of iran. soil samples from six sites managed differently were collected from a 0 to 30 cm depth. the results showed that land use and management systems had a significant effect on amf spore number in soi...

salinity is the major limiting factor for plant growth and crop productivity. salt stress is effective on physiological characteristics, morphology, anatomy, chemical composition and water content of plant tissue. pulses are the second of food source after the cereals for human. among the pulses, the bean has special importance. in order to investigate the effect of silicon on the physiological...

Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...

22 A GPS-based method is presented to measure vegetation water content. Commercially available 23 geodetic-quality GPS receivers and antennas are used. The method is tested using GPS 24 measurements collected over three field seasons. The GPS data are compared with in situ data 25 for three plant types: desert grass, wheat and alfalfa. The GPS retrievals or vegetation water 26 content are based...
