The study aimed to follow up the drought situation and the effectiveness of geospatial technologies in monitoring this phenomenon. The indexes and indicators of SPI, NDVI, VCI, TCI, VHI and WSVI were used to monitor the drought situation starting from 1999-2019 for soils within the western desert of Iraq in the Sakran region. The climatic drought index SPI showed that the region was affected by the drought condition with recurrence at intervals ranging every 5 years, while the WSVI hydrological index indicated that the region was affected by the drought condition and its variation from year to year with the predominance of moderate and severe drought. The results of the agricultural drought indices NDVI, VCI, TCI and VHI agreed with other evidence in terms of the region's affected by the state of drought, which was classified into five types whose areas of impact varied with the selected years of study with the predominance of severe dry cases.

To investigate the effect of stopping irrigation during different growth stages (As a simulation of water stress) in wheat growth, dry matter accumulation, and yield, an experiment was utilized by using the Randomized Complete Block Design (RCBD) included two wheat cultivars (Fayyad and Bora) and five non-irrigation treatments (control, no-irrigation at the seedling stage, no-irrigation at the tillering stage, no-irrigation at the flowering stage, and no-irrigation at the fulling seed stage) with three replications. The experiment was applied in the Field Crops Experiment Station located at University of Tikrit, Tikrit, Iraq during the 2021-2022 growth season. Total chlorophyll (mg gm-1) was extracted in each growth stage from control and no-irrigation treatment. The tillers number per plant (no. plant-1), flag leaf area (cm2), plant height (cm), dray matter (gm plant-1), and yield (kg m-2) were measured. The result indicated no difference between the two cultivars except in plant height. Fayyad was significantly higher in plant height 80.53 cm compared with Bora 76.53 cm. No-irrigation treatments reduced total chlorophyll significantly compared with control treatment by 11% in seedling, flowering, and fulling seed stages and by 16% in the tillers stage. No-irrigation at the tillering stage reduced significantly the number of tillers 21%, flag leaf area 43%, plant height 12%, and dry matter 19% compared with the control treatment. Also, the no-irrigation treatment at fulling and flowering stages reduced the yield by 36% and 28% respectively compared with the control. The outcome of this study will be useful to increase knowledge about the most sensitive growth stage to water stress in wheat, which contributes to better management of the irrigation process in desert and semi-desert areas and to spare plants water stress during those stages.

The experiment was done in a separate location “low and medium salinity soil and each location was consisted of three planting dates (15th March, 15th April and 15th May). In addition, cutting dates, i.e., (cuts were taken after 40, 50, and 60 days for each location) were distributed in a randomized complete block design (RCBD) inside the sowing date plots in every location with three replications. Results indicated that highest values of growth characters, total fresh and dry weigh per feddan (one feddan equal 4200 m2) of cowpea were resulted under the low level of salinity soil (3.35 dSm-1 over both seasons) in both seasons in all studied sowing dates. Sowing cowpea on 15th May optimizing all studied seed characters. On the other hand, the lowest values of seed characters of cowpea were recorded due to early sowing date on 15th March in both growing seasons. Results also showed that, increasing number of days to cut cowpea forage up to 60 days increased productivity of cowpea under low and medium levels of soil salinity at the three studied sowing dates in both seasons. So, sowing cowpea on 15th of May and cutting plants every 60 days in order to maximizing productivity of cowpea under soil salinity stress to meet climate changes and environmental stress.

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

A field experiment was conducted in one of gypsum soil private farm in Al-Dour district during autumn season 2019. The study aims to show the effect spray potassium concentration of 0, 2000, 4000, 6000 mg l-1 on growth characters and NPK percentage in popcorn plants var Noor. The experiment was applied by using RCBD with three replicates. The results showed that corn plants which sprayed with 6000 mg l-1 gave the highest significant values in plant height 148.06 cm , leave area 4396.3 cm2, leave area index 4.47, leaves number 14.4, plant dry weight 134 g, NAR 0.001789 g cm-2 day-1, CGR 0.002275 gm day-1 and percentage of K, N, and P of 3.591, 1.9, and 0.424% respectively. There was no significant different between 4000 and 6000 mg l-1 treatments in all studied characters. Therefore the spraying of 4000 mg l-1 was useful to improve growth characters and popcorn plant content of NPK.
