dry matter remobilization, grain filling rate and duration has principle role on rice grain yield, and environment condition directly affect on them. for study the influence of climate factors a factorial field experiment in randomized complete blocks design with three replications conducted at haraz extention and technology development centre in spring 2013. treatments included rice cultivars ...
Wheat grown in Mn-deficient soil has been widely observed to produce much reduced yields. Breeding for Mn-efficient wheat genotypes adapted to Mn-deficient soils would represent a long-term solution for wheat agronomy. To characterize the physiological basis of Mn efficiency in wheat genotypes would facilitate the breeding programs for producing Mn-efficient wheat. Using a solution culture and ...
Growth indices are useful for interpreting plant reaction to environmental factor. Using Growing Degree Days (GDD) for estimating the phonological growth stages is more valid instead of calendar time. In order to study effect of salinity on growth analysis in three different plantago species, a greenhouse experiment was conducted in Vali-e-Asr University of Rafsanjan in 2009. The study was carr...
according to the global water shortage problem, the exploring for reducing its harmful effects is very important. this experiment was conducted as split plots method based on randomized complete block design with three replicates in urmia university research field during growing season of 2013-14. water deficit stress as main plot consisted of three levels (irrigation when soil moisture reached...
The effect of soil salinity on plant growth is due to two factors, namely, increase in osmotic pressure of soil solution and the ionic composition of salt. The present experiment was conducted to obtain information about the response of pistachio (Pistacia vera L.) to salinity and ionic composition of the salt. Salinity with different relative composition of sodium chloride and sodium sulfate w...
This research was conducted to investigate the effect of growth-promoting bacteria on yield and some traits of maize. This experiment was performed as a factorial randomized complete block design with three replications at research farm of Islamic Azad University, Izeh branch, Iran. The experimental factors included four strains of plant growth-promoting bacteria: Pseudomonas fluorescent 169 (B...
Understanding the physiological processes associated with high yield traits in modern cropvarieties is essential to further increase grain yield and improve nutrient management strategies.Field trials were conducted to study the effects of fertilization and variety on the grain yield ofrice (Oryza sativa L.) with two fertilizer levels and 18 modern varieties. The objectives were toevaluate yiel...

in order to investigation of waterlogging stress effects on morphological and physiological traits of rapeseed in different developmental stages, a pot experiment was conducted at gorgan university of agricultural sciences and natural resources during 2010-2011. the experiment design was completely randomized with factorial arrangement and three replications. examined factors were developmental...
given the important role of crop growth indices for explanation of cultivars yield differences in diverse environmental and agronomical circumstances, this experiment was conducted at research field of tarbiat modares university during 2007 growing season. experimental treatments were arranged in split-plot layout based on randomized complete blocks with four replications. in this research, sow...
