In the major wheat growing countries, wheat growth and yield are negatively affected by salinity and breed tolerant cultivars through selection and breeding techniques is necessary to solve this problem. Relationship among yield, and its related traits in 23 wheat cultivars and promised lines were studied under salt stress conditions using a randomized complete block design with three replicati...
in order to evaluate the effects of drought stress and planting method on yield and yield components of two chickpea cultivars (cicer arietinum l.), an experiment was carried out at the research field of faculty of agriculture; shiraz university, using a split factorial randomized complete block design with four replications. the main factor was irrigation stop at different growth stages of chi...
In order to investigate the effect of methanol on the activity of antioxidant enzymes, some compatible osmolytes and biochemical traits of wheat under cut off irrigation conditions, the present experiment as factorial was conducted based on randomized complete blocks design with three replications at the research farm of Faculty of Agriculture and Natural Resources of University of Mohaghegh Ar...
to study the effects of drought stress and foliar application with salicylic acid on yield andit’s components and percentage of essential oil of nigella sativa l., a field experiment was conducted as split plot based on randomized complete block design with three replications at research farm of shahid bahonar university of kerman during growing season of 2013- 2014. the main factor was drought...
TThis study was undertaken with the objective to determine the association between grain yield and its components and identifying traits have the greatest effects on grain yield of 45 mutant lines from tarom-mahaliin a randomized complete block design with three replications. Analysis of variance showed significant differences among genotypes for all traits. Mean comparison showed that line 2...
predicting the impacts of climate change on irrigated wheat yield in fars province using apsim model
background and objectives: over the last decade, climate change has been one of the most challenging issues in the scientific papers. studying the impacts of climate change on crop productivity at regional scale will depend on the right estimate of future climate. this estimation is being implemented by climate models and most of them by general circulation models (gcms). this study aims at pre...
With the aim of comparing the grain yield and yield components of 16 oilseed rape (Brassica napus L.) mutant lines with cultivars Talayeh, Zarfam, Express and Okapi as check cultivar an experiment was conducted based on randomized complete block design with three replications during 2015-2016 cropping season in experimental field of Seed and Plant Improvement Institute (SPII) in Karaj. Analysi...
Three maize hybrids (Baber, Pioneer 30P45 and Syngenta 6621) were compared for yield and yield components and correlations were worked out among the yield parameters at various nitrogen levels in an experiment conducted at Agricultural University, Peshawar, Pakistan during summer 2009. The experiment was laid out in randomized complete blocks with split plot arrangement having three replication...
Mutagenesis has been one of the important sources of genetic diversity and Plant mutants can be important bio-resources for crop breeding and functional genomics studies. Breeding conventional methods for generating of genetic variability are of low efficiency. We showed that treatment of seeds of rice(Hashemi cultivar) with 0.8% EMS for 8 h caused visible phenotypic variations on M2 rice mutan...
water deficit stress, permanent or temporary, limits the growth and the distribution of natural vegetation and the performance of cultivated plants more than any other environmental factors. mechanism involved is still not clear. in order to investigate the effect of different irrigation intervals and anti-transpirants compoundson yield and yield components of black cumin (nigella sativa), an e...
