Abstract: 

Regarding to water resources limitation and knowing this matter that about 40% of the world's land is managing by dry farming system, therefore improving management of dry farming system is important issue. This paper is intended to assessment the effects and variations of rainfall on the annual dry farming of wheat, base on the least number of rainfalls. Hamedan state has been chosen as a case study and for covering all rainfalls, four weather station, located in areas under dry farming system have been selected. For best assessment, the new index as indicator of Time-Rain (RTI) has been introduced. This indicator has the combined capabilities of assessing the changes of both factors of time and amount of rainfall on the annual dry farming yield. The effect of each intermittent rainfall on the annual dry farming yield of wheat is calculated by using the multi regression that defined base on the RTI index. The results show, the differences and the effects of each intermittent rainfall have been indicated better by using RTI index. The rainfalls in autumn and winter are more reliable and knowing the effects and impacts of those rainfalls are more practicable. This research also indicates that importance of the autumn and winter rainfalls are depends on the climate of region.
