Drought is one of the major environmental stresses that adversely affect crop growth and productivity worldwide. For evaluation of drought stress on grain yield, yield components and drought tolerance indices, 20 genotype of rapeseed (Brassica napus L.) was studied in an experiment based on a randomized complete blocks design with three replications in two different conditions (stress and non-s...

The research on reducing the water consumption in conventional cropping system is one of the important strategies to improve the water use efficiency in agriculture. In order to investigate the effect of time of potassium application under different irrigation regimes on millet grain yield and protein percent, a field experiment was carried out in Agricultural Research Center of Yasuj, Iran, in...

In order to find drought tolerance cultivars and determine the appropriate Indices to select drought tolerance in sunflower hybrids, an experimental research was conducted as split plot design based on RCB at the research field of college of Abouraihan of university Tehran in Iran-Pakdasht, in 2009. Irrigation rates were considered in the main plots and sunflower hybrids as sub plots. The resul...

a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...

cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...

Performance of any breeding program is mainly due to the correlation among yield and relative importance of each component. This study was conducted to analysis the correlation among grain yield and some important traits in seventhin spring canola (Brassica napus L.) cultivars at the farm in safiabad, from 2014 to 2015. A randomized complete blocks design with four replications was used. The an...

  This research was conducted in order to determine the relationship between grain yield and yield components, using 30 common bean varieties in a randomized complete block design with four replications at the Agricultural filed faculty of Agriculture,Tehran university In this study 18 traits were assessed on 10 random plants from each plot. The result showed that there were significant differe...
