introduction integrated weed management is based on combination of several management methods, while reducing the rate of the use of herbicides, will result in efficient management and sustainable weed control. ability of crop tolerance and prevent weed growth are two important traits in weed competition. an appropriate and suitable cultivar, has high yield potential in the presence of weed and...

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...

continuous desertification of arable lands mandates use of low quality/ saline water for irrigation, especially in regions experiencing water shortage. using low quality/ saline water for irrigation imposes more stress on plants that are already under stress in these regions. thus, a logical solution will be to find a salt/ drought-tolerant plant species that will survive/sustain under such str...

The main objective of this research was to evaluate fifteen durum wheat (Triticum durum) genotypes selected from joint project of Iran/ICARDA for drought tolerance using several indices. The trials were conducted under moderate levels of drought stress for three cropping seasons (2004-2006) in four locations in the highlands western of Iran. The combined ANOVA for grain yield over years and loc...

in order to evaluate the relationships between some traits of iranian rice seedlings under saline conditions,,75 iranian cultivars as traditional, improved and introduced cultivars were used, as a randomized complete block design experiment with 3 replications at rice research institute of iran in three levels of salinity (normal ,1.2 , 4 and 8 ds.m-1) in 2006. root and shoot length, root and s...

This paper presents a neural model for reliable and fault tolerant transmission in Wireless Sensor Networks based on Bi-directional Associative Memory. The proposed model is an attempt to enhance the performances of both the cooperative and non cooperative Automatic Repeat Request (ARQ) schemes in terms of reliability and fault tolerance. We have also demonstrated the performances of both the s...

Although water and land pollution are very dangerous, air pollution has its own peculiarities due to its transboundary dispersion of pollutants over the entire world. In any well planned urban set up, industrial pollution takes a back seat and vehicular emissions take precedence as the major cause of urban air pollution. In the present study, Air pollution tolerance index was calculated for var...
