BACKGROUND The proportion of proposed new treatments that are 'successful' is of ethical, scientific, and public importance. We investigated how often new, experimental treatments evaluated in randomized controlled trials (RCTs) are superior to established treatments. OBJECTIVES Our main question was: "On average how often are new treatments more effective, equally effective or less effective...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
a field experiment was conducted in research farm of isfahan university of technology, isfahan, iran in 2011 . various weeding periods were investigated on growth and yield of potato under drip tape and furrow irrigation systems. a split plot arrangement was used in a randomized complete block design with three replications. irrigation treatments were included in main plots and periods of weed ...
water stress is one of the main factors affecting the quantity and quality properties of sugar beet. the objective of this experiment was to study the effect of irrigation management on quality and quantity of sugar beet. the present research was conducted in motahary station of sugar beet seed institute,karajin two years, 2005 and 2006. the experiment was based on split plot design, in which e...
In order to study the effect of salicylic acid and selenium foliar application on physiological characteristics, yield and yield components of safflower (Carthamus tictorius L.) under drought stress conditions, an experiment was conducted as split plot based on randomized complete block design with three replications. The main factor included irrigation in three levels, complete irrigation duri...
To alleviate water scarcity problem in arid and semiarid regions of Iran, different irrigation methods such as deficit irrigation, pressurized irrigation and partial rootzone drying (PRD) method have been suggested. In PRD method, half of the rootzone is watered and the other half is kept dry intermittently. The objective of this research was to study yield, yield components and water use effic...
high yield of top quality crop is a prerequisite for profitable production of greenhouse produced cucumber. on the other hand, because of water deficit in iran it is necessary to economize in this scarce and valuable input. an experiment was carried out in the experimental greenhouse of university college of agriculture and natural resources, university of tehran to optimize water use in soil c...
Agricultural investigations use computer models for simulation of crop growth and field water management. By using these models, the effects of plant growth parameters on crop yields are simulated, hence, the experimental costs are reduced. In this paper, the model of MSM (Maize Simulation Model) was calibrated and validated for the prediction of maize forage production at Agricultural College,...
a field experiment was performed in order to evaluate the effects of irrigation and application of k fertilizer on seed storage proteins in chickpea, ilc-482 cultivar. experiment was performed in factorial using randomized complete block design with three replications. in this experiment, two factor consist of irrigation in three levels (i1= non irrigation and i2= irrigation in flowering stage...
