The purpose of this study was to estimate the economical effect of climate change on wheat production in the northern stat. Secondary data was obtained from official sources in Khartoum and in the northern stat and from the internet. Descriptive statistics modeling average and correlation were used for analysis of crop and climatic factor data. The results of the study revealed that the yield of wheat has dropped from 1304 kg/fed in 200/03 down to 1132 kg/fed in 2003/04.these yields were achieved at the experience of high temperature increase from 27.9I0;C in November 2002/03 to 28.9I0;C in November 2003/04, from 21.5I0;C in December 2002/03 to 24.4I0;C in December 2003/04, from 18I0;C in January 2002/03 to 23.8I0;C 2003/04, and from 20.4I0;C in February 2002/03 to 20.4I0;C to 22.6I0;C in February 2003/04. The results also showed that sowing in November had a positive relation with high yields of wheat contrary to late sowing in December, January and February, which gave a negative correlation during the last 25 years from 1981- 2005. The study concluded that the improved varieties play a crucial role in increasing yield in the state. The study also recommended improvement in training of researchers, availability of funds in optimum time, timely cultural operations as well as provision of sufficient irrigation and use of improved varieties
