“…Besides, available water enhanced the production and transporting of dry matter content to the panicle resulting in more grain weight. These data are in agreement with those reported by Mosalem et al, (1998), El-Sharkawy et al, (2006, Okasha et al, (2009), Abu and Malgwi (2011) and Raumjit and Wichitparp (2014).…”

“…Several researchers showed that increases the irrigations intervals, wherever, allowed the rice fields to dry for a few days in between irrigations intervals for 6 to 8 or 9 up to 12 days. Similar information reported by Mosalem et al, (1998), El-Sharkawi et al, (2006), Okasha et al, (2009), Abu and Malgwi (2011) and Raumjit and Wichitparp (2014). The interval of 6 days gave reasonable production of rice grain and most of its components, as mentioned by El-Kalla et al, (2006), as well as El-Bably et al, (2007).…”

in the two successive seasons 2011 and 2012 to study the performance of five new genotypes of rice under three irrigation intervals on yield and yield attributes. The most important results obtained from this study can be summarized as follows: The highest values were recorded under irrigation intervals of 3 days, followed by irrigation every 6 days, however, the extra of the studied traits increasing irrigation intervals to 9 days significantly reduced the obtained characters values for all of the studied characters in both seasons under the two locations. Results showed that irrigation each 3 days allover the growing season gave reasonable production compared with irrigation every 6 and 9 days. The GZ7576 genotype was of the earliest heading compared with the other rice genotypes in both seasons. While, Sakha106 genotype gave the highest values of root length, No. of panicles hill-1, No. of panicles m-2, panicle length, No. of grains panical-1, grain index and grain yield fed-1 in the both seasons at two locations. Significant interaction effect for irrigation intervals and rice genotypes was obtained for No. of panicles m-2 in the first season and heading date, No. of panicles hill-1, panicle length, No. of grains panical-1 and grain index in the second season at Moshtohor location. While, No. of panicles hill-1 in the both seasons and No. of panicles m-2and grain yield fed-1 in the first season were significantly affect by the interaction between irrigation intervals and rice genotypes at Kafrelshiekh location. Generally, irrigation every 3 days under Sakha 106 genotype treatment recorded the highest values for the studied traits in both seasons at two locations.

“…The highest WS values were observed at closer distances to the Shatt al-Arab, with values decreasing towards more distant barren areas. [14].The distance of 300 meters recorded the highest WS value at 684.41 m 3 , significantly surpassing the other distances. Following this was the distance of 600 meters, which recorded 580.76 m 3 , then 1200 meters with 515.45 m 3 , and finally, the distance of 2400 meters recorded the lowest value at 424.33 m 3 .…”

A study was conducted in the semi-arid and arid region located in the northeastern part of Basra Governorate, southern Iraq, with the aim of employing geomatics techniques and mathematical modelling to build and develop a hydrological model for studying water balance in the study area and the volume of water supply from the Shatt Al-Arab river towards adjacent areas and its impact by soil salinity and Shatt Al-Arab river water during July 2022. The results indicated a decrease in water supply (WS) values in the soil profile with increasing distance from Shatt Al-Arab or from the tributaries and other water sources. At a distance of 300 meters from the water source, the highest WS values were recorded, amounting to 684.41 m3, significantly higher than other distances. This was followed by the distance of 600 meters with 580.76 m3, then 1200 meters with 515.45 m3, and finally, the distance of 2400 meters recorded the lowest values at 424.33 m3. The magnitude of decrease in WS values increased at high rates with increasing distance from Shatt Al-Arab towards remote barren areas with a significant correlation coefficient (r =0.73).
