Estimation of base temperature in different growth stages wheat Case study: Sararood Station Kermanshah

this study was conducted to determine grain yield stability of rainfed promising barley genotypes across six rainfed research stations (maragheh, sararood, uromieh, qamloo, zanjan and ardabil) under cold and semi-cold conditions during three cropping seasons (2006-2009) in iran. the studied genotypes were 10 promising barley lines along with two checks (one local and one newly released variety,...

The goal of this study was to apply artificial neural networks to predict rain-fed wheat yield using meteorological data a few days to few months before harvesting. The climatic observation data used; were mean of daily minimum and maximum temperature, extreme of daily minimum and maximum temperature, sum of daily rainfall, number of rainy days, sum of daily sun hours, mean of daily wind speed,...

to determine chromosomal localization and relationship between field and laboratory indicators of drought tolerance, an experiment was conducted in 2003-2004 cropping season at sararood agricultural research station, kermanshah, iran. seven genotypes of wheat-barley disomic addition lines provided by international center for agricultural research in dryland areas (icarda), their donor and recip...

In order to evaluation of drought resistant indices in barley (Hordeum vulgare L.), 10 barley genotypes evaluated in Completely Randomized Design with three Replications in two conditions, (under drought stress and in normal with irrigation in planting, flowering and grain filling stages) in Islamic Azad University, Miyaneh Branch Research Farm in 2012. Drought tolerant indices basis of yield p...

introduction climate change generally affect all economic sectors, but the agricultural sector is the most sensitive and vulnerable sector, because crops are highly dependent on climatic resource. according to the scientific evidences, climate change in the future, especially the combined effects of rising temperatures and rising co2 concentrations in the atmosphere and increase the likelihood ...

The effect of supplementing two commercial multienzyme to diets included two barley cultivars (Sararood [71.99%] and Valfajr [66.39%]) on performance, egg quality, and blood parameters of laying hens was investigated in an 8-wk (65 to 73 wk of age) experiment.  The commercial multienzymes were Grindazym™ (with mainly β-glucanase and xylanase activity) and Hemicell® (with mainly β-mannanase acti...
