drought stress is the most important environmental constraint contributing to grain yield instability of maize(zea mays l.). evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. this study was conducted to estimate grain yield stability of maize hybrids and to identify hybrids th...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
in order to study the effect of water deficit stress at different growth stages on yield and seed oil quality of rapeseed cultivars, a field experiment was conducted as split-plot in a randomized complete block design arrangement with three replications in 2009-2010 growing seasons in abarkouh in iran. four levels of irrigation were located in the main plot including, (i1) normal irrigation bas...
abstract in order to study the effects of different irrigation management on water productivity of local, improved and hybrid rice varieties an experiment was carried out on a split plot design with 3 replications. the varieties were splited on 5 irrigation methods (i.e. full irrigation, awd, 5, 8 and 11 day irrigation interval) at rice research institute of iran, rasht during cropping season o...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
we investigated the response of sea buckthorn to drought in a nursery experiment that has been studied for the first time in the world for iranian sea buckthorn. biomass and physiological differences in response to drought were compared between four elaeagnus rhamnoides seedlings inhabited in qazvin province origin seeds of iran. the experimental design included four water regimes including 2, ...
water deficit is one of the most important problems facing crop production in arid and semiarid regions in iran. application of super absorbent polymers may somehow control yield reduction in some crop plants under drought stress conditions. in this investigation, the effect of different levels of super absorbent polymer, superab a200 (0, 100, 200, 300 kg/h), and three irrigation intervals (7, ...
in order to study the effect of irrigation interval, n fertilization and plant density on yield and yield components of fenugreek, a split-split-plot experiment was conducted in darmian, iran in spring 2010. the experiment was conducted in randomized complete block design with three replications. the main plots were subjected to different irrigation intervals of 5 and 10 days. the sub-plots wer...
to evaluate the effect of arbuscular mycorrhizal fungi under water deficit stress on linseed, a field experiment was conducted as split-plot in rcbd design with three replications at the research station of faculty of agriculture at shahrekord university in 2013. water deficit stress at four levels of no stress, mild, medium and severe stress as main factor and inoculation with glomus intraradi...
