Abstract

Wheat (Triticum aestivum L. ) as one of the most important agronomic crops has a special status in Iran. Reducing the yield gap is one of the ways to raise the production. In order to, the production rate and thewheat yield gap in Golestan province were analyzed by using a simple simulation model SSM– Wheatand GIS software. For this purpose, the managerial information of wheat farming and cultivation werecollected based on the provincial level and with regards to the information of 25 weather station and theregion soil information, the POTENTIAL YIELD was simulated in the irrigated and rainfed conditions at theprovincial level and then the POTENTIAL YIELD zoning was performed in the GIS and then with regards to thefarmer's production rate and real yield at the provincial level, the yield gap and the production one werealso calculated in the irrigated and rainfed conditions. Results indicated that the yield average of irrigatedand rainfed potential with regards to the figures and current agricultural methods are respectively 8. 140and 4. 930 kg per hectare. Also, the potential production in the irrigated and rainfed conditions wasobtained equal to 1. 357 and 1. 112 million tons (total 2. 469 million tons). Results showed that in case ofstudying and removing the factors which may cause the yield gap in the said province, the wheatproduction can be increased from the current 926 thousand tons to 1. 975 million tons. Based on theresults of Golestan province, the most important factors causing wheat yield vacuum with currentcultivars and agronomic management, improper irrigation management, improper cultivation of cultivarsand inappropriate use of basic fertilizers, road and low fertilizer, and for eliminating yield vacuum, use of165 to 215 kg of seed per hectare, using certified seeds of suitable cultivars for water and dry farming, consuming at least 50 kg of phosphorus fertilizer (equivalent to P2O5) during cultivation, consuming atleast 95 kg of pure nitrogen per hectare and integrating farms are suggested.
