Abstract

The study area is about 54676 hectares and located in south-west Tehran province, between 35o 30’ to 35o 45’ north latitude and 51o to 51o 15’ east longitude. The nearest synoptic station data show that the climatic type is sub-desertic. The maximum and minimum daily air temperature 36.6o C in July and -0.4o C in January, respectively. The annual rainfall is about 233 mm. The main aim of this research was to elaborate an approach to estimate land production potential for irrigated wheat, taking into account the environmental conditions in the study area, the methodology considers different hierarchically ordered production situations. In the first hierarchically production situation, the radiation-thermal production potential (RPP) or the irrigated yield for wheat has been calculated. In the second hierarchically production potential situation, land production potential (LPP) for phases of family has been calculated considering soil indices. The result of the first hierarchically production situation showed that potential irrigated yield based on Sys method in south-west Tehran province is 10484 kg/ha. In the second hierarchically order, land production potention for each soil unit was calculated based on radiation - thermal production potential and soil limiting factors, which the result was predicted 1856 to 8775 Kg/ha and 1940 to 8870 Kg/ha using Storie and square root methods respectively. This reduction was due to limiting factors such as soil physical characteristics, drainage, pH, salinity, alkalinity and slope. After reclamation of some limiting factors, the future LPP will be 3743 to 10253 Kg/ha and 3774 to 10253 Kg/ha with Storie and square root method respectively. Finally predicted land production potential (LPP) was compared by farmers yield (observed yield) and showed a good correlation with r=0.97. So this model can well be prediction of land production potential for wheat in the studied area.
