Abstract

In order to evaluate the effect of some antitranspirants on plant traits, yield and yield components in soybean (Glycine max L.) under limited irrigation an experiment was conducted in the research field of Urmia university in 2010. The experiment was arranged in a complete randomized block design with four replications. Antitranspirants consisted of Kaolin (6%), Chitosan (0.1%), castorbean oil (1%), magnetic water and control ( without antitranspirant ). These materials applied 60 days after planting (flowering stage) and in seed formation stage. After spraying the plants with antitranspirants, irrigation in these stages were interrupted in all plots and irrigation intervals increased from 10 days to 20. The results showed that the application of antitranspirants significantly increased stem height, node number, stem diameter, number of pods and number of seeds per plant, thousand seed weight, seed yield, biological yield and harvest index in treated plants but the number of seeds per pod was not affected by these antitranspirants. Among the materials used kaolin had the most influence on seed yield thus seed yield increased %23/85 compared to control . Findig this experiment suggest that using antitranspirants can be effective by reducing the effect of water stress in soybean product.
