The study of the drought phenomenon gets considerable attention in the recent applied climatic studies since it has an enormous effect on the environment. The drought has various impacts according to its strength and the capacity of society influence, besides it affects the vegetarian sources due to reducing the vegetarian. The reduction of the vegetation is correlated with the drought, and if the range of drought has raised the reduction of the vegetation is increased. This happens when the temperature is raised in the summer seasons or dropped. When the rain comes down, the vegetarians come to spring as it is the time of their growth, expand and density according to the amounts of rain to form thick vegetarian cover in wet seasons. There are three seasons; Autumn, winter, and spring as the range of rain is between 57-58% in the fields of the study area. Where as in the drought seasons becomes between 41-42% in the same seasons. Applying the (SPI: Standardized-Precipitation Guide - Index) to evaluate the lack of rain with the exception of the summer season in which it is always dry. Consequently, we can find the relationship in plant covers via the years of study which shows a variable difference form one year to another. In 1993, the current category was weak as it reached 10240 km2, which constitutes 57.80% of the height of dry seasons. In 2017, there was the opposite of previous years due to the increase of the wet seasons which led to the increasing area of the dense variety to reach an area of 9804 km2 which constituted 55.28% of the study region

The study showed an increase in the properties of leaf area for sapling, branches number, chlorophyll content, the percentage of dray matter in leaves and percentage or ripened wood and total wood when Algae extract treatment 1.5 g.l-1 to (284.79 dcm2, 3.33branch .Sapling-1, 41.89 mg.g-1 fresh weight, 46.58% and 84.93%), respectively, While it decreased in control to (109.60 dcm2, 2.08 branch .Sapling-1, 33.58 mg.g-1 fresh weight,38.52% and 46.44%), respectively. The percentage of dray matter in branches when Algae extract used 3 g.l-1 increased to 46.52% while its decreased in counted to 39.65%.

Adaptability of Plant species (crops) cultivars could be characterized using their performance via certain trait over given environment. Thus, multi methods were applied to investigate this adaptability ofv10 cultiraj from caraway. Therefore, ternary plot conducted out at first time in middleeast especially in Iraq to test ten cultivars of caraway adaptation via carvone% and its yield (kg.ha-1) across two locations, Fallujah and Ramadi for two successive seasons, 2011/2012 and 2012/2013 to become four environments. AMMI biplot laid out to support ternary plot. Past software used to construct ternary plot graphs. Also cropstat 7.2 software to extract cultivars and envirronments biplots. Results reveald that ternary plot method sorted cutlivars into three categories relied on carvone% viz non-adaptable cultivars included G4. While the other two categories involved cultivars those had two behavors once adaptable again non-adaptable that located on straight line between Ibottom and Itop the last one included cultivars that once behad near to Itop again to Imiddle that located on mid of triangle. According to carvone yield, G3 is semi-adaptable across four environments, whereas, AMMI Biplot precisely showed that G3 and G7 were most adaptable over most evnvironments. Thus, G7 was the most adaptable genotype.
