Abstract:

In order to investigate the interactive effect of different levels of nitrogen and drought stress on yield and yield components of the Mung Bean,  field experiment was carried out in the city of Ahwaz field healthy martyr in a split plot randomized complete block design with four replications in crop year of 2011-2012. In this experiment three levels of drought stress (50, 75, 100 mm evaporation from class A evaporation pan) as the main factor and three levels of nitrogen (50, 100, 150 kg/ha) as the sub factor were examined. The results of the research showed that the effect of different levels of drought stress on the grain yield, number of grains per pod, 100-grain weight, and number of pods per plant was significant, so that the highest rate of grain yield, number of grains per pod, 100-grain weight, and number of pods per plant belonged to the treatment with 50 mm evaporation. Furthermore, the results showed that the effect of different level of nitrogen on abovementioned traits was significant except the number of pods per plant and 100-grain weight. The results also showed that drought stress had a negative effect on most agronomic and physiological traits associated with the yield, but nitrogen fertilizer had a positive effect on them.
