ABSTRACT- The crop water stress index (CWSI) is the most common index to monitor and assess crop water stress, based on canopy temperature. To calculate CWSI, upper and lower baselines adaptable to different environments are needed. In this study, empirical and theoretical limiting baseline equations were developed to determine eggplant CWSI values at different levels of water deficit and salin...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
the effects of water deficit on grain yield, yield components and the physiological char-acteristics of barley (hordeum vulgare l.) varieties were studied in a split plot design dur-ing the 1999-2000 growing season in karaj, iran. five irrigation levels [0, 25, 50, 75, and 100% crop water requirements (cwr)] and six barley varieties karoon kavir , rei-hani(drought tolerant), torkman , c-74-9 (i...
ABSTRACT Water management is an essential concept for water intensive crop such as maize dealing with water shortage under drought conditions. Maize production is ranked after wheat and barely in Fars province, Iran. Therefore, the present study was conducted to investigate the effects of planting methods by conventional and modified planters on maize growth and yield at different irrigation re...
Drought stress is one of the most important factors threatening the growth and development of ornamental plants around the world. Clearly, the use of active ingredients that increase drought resistance in plants is very important to reduce the economic losses of ornamental plants in landscapes. For this aim, a study was conducted to evaluate the effects of sodium hydrochulfide on Amaranthus pla...
Abstract Terminal drought stress is one of the most important environmental stresses affecting plant morphology and physiology and has major effects on agricultural production. The purpose of this experiment was to investigate the effect of water deficit stress on changes in physiological traits of wheat in a randomized complete block design with three replications in two cultivation years of ...
the world is facing a dwindling supply of water, therefore deficit irrigation is becoming more of a necessity than a choice. partial rootzone drying (prd) is a new water saving irrigation technique where at each irrigation time only one part of the rootzone is watered. the un-irrigated part is watered during the next irrigation. we explored the potential of prd for `petopride´ processing tomato...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
Nitrogen has an important role for supplying carbon skeletons which needs for producing compatible solutes and stress tolerance enzymes. Water deficit affects nitrogen fixation in legums. So we studied the effect of various nitrogen sources on physiological, and biochemical features of bean under water stress. This experiment was conducted as factorial based on completely randomized design with...
in order to study the effects of integrative applications of chemical fertilizers and biofertilizers on grain yield and oil of borago officinalis under water deficit stress, a field experiment was conducted at kermanshah, iran, in 2011. experiment was arranged as split plot under a randomized complete block design with 3 replications. water deficit stress with four levels was applied as the mai...
