| The phenomenon of warming is global, in fact, but its strength varies from one place to another and from one time to another. This difference is due to the causes of this phenomenon contrast. In the study area proved the existence of time clear contrast to this phenomenon. As proved by the trend line that the value of coefficient of increase temperatures rates were varied from month to month but the increase was more months of March, which amounted to a trend line towards the 0.1077 and so this was the most warmest month between months. The amount of water consumed by the rice crop by separating growth was increasingly are other progress-year study period, in line with the warming phenomenon. The month of June was the first month of the separation of rice crop growth in terms of water consumption rising trend line value of about 0.668. And statistically proven that the Pearson correlation coefficient was strong and months, the whole growing season. Which indicates that the water consumption linked to the phenomenon of warming power during the years 1981 to 2010 period. The strength of the correlation coefficient varied from month to month, and it was less closely months is about the month of July 0911. The strongest month in association coefficient was the month of April, as it was about 0996. In applying the test (t) the results indicate that the values of (t) calculated over the value (t) Indexed for months separating all rice crop growth without exception. The R2 value indicates the high value of warming and its role as head of an influential increase in water consumption during the study period, with the decline in the value of the amount of the contribution of other factors statistically. | ||
