Abstract:Çeltik yetiştiriciliğinde geleneksel göllendirme sulama uygulandığı için
diğer bitkilere oranla çok daha fazla su kullanılmaktadır. Bu nedenle, kurak
yıllarda çeltik yetiştirilen alanlara sınırlamalar getirilmektedir. Bu çalışma,
çeltik (Oryza Sativa L. cv. Luna)
bitkisinde su tasarrufu sağlayan yöntemlerden damla sulamanın (DI) ve su tutma
bariyerinin (STB) göllendirme sulama yönteminin uygulandığı çiftçi uygulaması
ile arasındaki su kullanımı, verim ve kalite özelliklerindeki farklılığı

“…The same researchers stated that total irrigation water amount would decrease up to 1,220 mm in application of subsurface drip irrigation. Nar et al, (2018) also calculated the amount of water required for paddy rice irrigation with drip irrigation as 1,375 mm, which is compatible with other literature. The irrigation water requirements in the current situation in case of using drip irrigation application, which were calculated and summarized in Table 6.…”

“…Considering the local conditions and the farmers preference, the amount of water used by the ponding method has been revealed as a priority. Nar et al, (2018), stated that the water used in ponding method in paddy rice production in one irrigation season is approximately 5,580 mm for the Enez, a neighbouring district with similar climatic and soil conditions. The same value was considered in the calculation of the water used in the ponding.…”

“…After the actual paddy rice cultivation area was determined using Sentinel 2 satellite image and RF algorithm, the paddy rice water requirement was calculated based on the climatic conditions of the region according to both the traditional ponding method and the drip irrigation method. As explained in the method section, it is stated that the application of the ponding method in regional conditions is 5,580 mm (Nar al., 2018). This figure reveals an irrigation application of more than 4,000-5,000 mm as reported in Özgenç and Erdoğan (1988).…”

“…It is normal to have yield losses with drip irrigation method. Nar et al, (2018) reported the yield losses encountered in drip irrigation in the study region. They stated that while the yield of 708 kg da -1 was obtained in the ponding irrigation method in which 5,580 mm of water was applied, this yield decreased to 576 kg da -1 with drip irrigation.…”

“…In Türkiye and especially in the Marmara Region, studies on the application of subsurface and drip irrigation (DI) methods have been started in paddy rice cultivation in recent years. Nar et al, (2018) determined the performance of DI with water retention barriers in same region. They reported that water applied in conventional, drip irrigation and drip irrigation + water retention barrier applications were 5,580, 1,375 and 930 mm, respectively.…”
Paddy rice irrigation takes an important role in water consumption. Therefore, the savings to be made in paddy rice irrigation will have significant impacts. In the sustainable use of water resources, both the irrigation methods and the methods to be used in the planning of water resources are critical. Hence, the use of drip irrigation should be expanded. On the other hand, the use of modern satellite technologies and machine learning models should be used while planning irrigation. In this study, Google Earth Engine (GEE), which is a cloud-based image processing platform was employed in the calculation of paddy rice cultivation areas. Random Forest (RF) and Support Vector Machines (SVM) machine learning algorithms were applied. The results showed that RF algorithm can calculate the paddy cultivation areas with an accuracy of 97%. A difference of 27.69 km2 was found between the officially declared cultivation areas and the calculated area. This can yield a miscalculation of water requirement with an error of 33.8, 38.1 and 155 million m3, in subsurface drip irrigation, drip irrigation and basin irrigation methods, respectively. Results showed that accurate calculation of paddy rice cultivation areas and drip irrigation will both minimize this error and allow 4 times more area to be irrigated.

Nowadays, as the pressure of drought on water resources increases, new approaches regarding paddy rice irrigation, which has the highest water consumption rate, need to be taken into consideration.One of these approaches is the drip irrigation system, which saves significant amount of water in paddy rice irrigation.. In this study, 4 different irrigation subjects (25%, 50%, 75% and 100%) in drip irrigation system for paddy rice in Edirne were examined in TAGEM-SUET. As a result of the study, the evapotranspiration of paddy rice during the production season was calculated as 692.83 mm, the amount of irrigation water was calculated as 162-486 mm in drip irrigation. In the model, it was measured that the optimum drip irrigation program would not cause a decrease in efficiency despite saving 38% of water compared to the ponding method. It is thought that TAGEM-Suet can be a good tool for irrigation planning and management of paddy rice, depending on climatic conditions.
