“…Several extension bulletins for improving water use efficiency have been published and are available to Michigan and Indiana farmers and industry stakeholders (Dong et al, 2020a, 2020b). In addition, the potential benefits such as water and energy savings through retrofitting the irrigation system have been demonstrated (Dong et al, 2023). However, the information on recommended designs of centre‐pivot and drip irrigation system for specific crop types are lacking.…”

Irrigation plays a critical role in Michigan and Indiana, USA, supporting various crops such as commercial corn, seed corn, soybeans, potatoes, fruit and vegetables. Irrigated lands in Michigan and Indiana have continuously increased over the last 20 years. As Michigan and Indiana have experienced more erratic precipitation and warmer temperatures, more irrigated lands will be projected. This study focused on understanding the changes in irrigation in Michigan and Indiana using USDA NASS data. The observation of changes from 2002 to 2017 helped to identify the critical considerations for developing future irrigation research and extension programmes in Michigan and Indiana. The study found that continuation of the collaboration with stakeholders, including state regulators, government staff, commodity groups, the irrigation industry and farmers, will be important to disseminate the most up‐to‐date irrigation information effectively to farmers. As more new irrigated lands are expected, outreach programmes for the optimal design of irrigation systems for specific crop types should be developed. Moreover, an easy‐to‐use and affordable irrigation scheduling technology is needed to increase the adoption rate of scheduling tools, ultimately improving irrigation water and energy use efficiency and minimizing environmental impacts.

“…It is considered an efficient way to evenly irrigate large scales, and since their inception, it has improved dramatically in reliability and preventing water loss. The center pivot irrigation system is the most popular sprinkler system in the world (Waller and Yitayew, 2016;Dong et al, 2023). Center pivot irrigation systems have been used in corn, soybean, potato, alfalfa, C AGRICULTURAL IRRIGATION AND DRAINAGE ENGINEERING wheat, cotton, vegetables, and sugar beet fields (Grassini et al, 2011;Hines, and Neilbling, 2013;Grassini et al, 2015 andAlptekin, Y., 2011).…”

The national Egypt strategy for sustainable agricultural development (SADS-2030),focuses on increasing agricultural area by approximately 1.5 million feddan to address the food gap. The central pivot irrigation system is one of the most effective ways to achieve this goal. Maintaining a center pivot device is hard. Moreover, repairing the damage that happens after the malfunction of the device will be timeconsuming and costly. So, the main goal of this study was to monitor, detect early error and warn the operator before starting any irrigation process, which prevents a malfunction or crash of the center pivot. The developed monitoring systems use NTC thermistors and an oil level sensor to monitor oil temperature and leaks in the gear box and motor. Tire pressure monitoring sensor (TPMS) was used to monitor towers' tires pressure. These sensors were installed in a unit known as "Tower/central node board" which consists of two ESP32 microcontrollers installed inside the main control panel. The main control panel of the device collects all the vital readings from all towers and communicates them with the cloud server using the internet, which allows the remote control of the device. Field tests were performed by using a "Valley" center Pivot System at the Egyptian Ismailia governorate's conditions, for detecting the sensitivity and accuracy of the system. Data was collected from two towers of the center pivot system and analyzed in a simple digital model that was used to process and decide on possible maintenance instructions.

The objective of any pivot irrigation system is to ensure uniformity of application of water which can be achieved when responsible factors such as pressure, drop tube lengths, nozzle size etc. are adequately designed. This indoor experiment conducted in a 44m2 laboratory facility tends to evaluate the extent of the influence of some sprinkler design parameters on the performance of a low pressure single pivot sprinkler spay unit. The parameters considered are; pressures of 9,12, 15 and 19Psi, nozzle sizes of 4.17, 5.56, 6.95 and 8.14 mm and drop tube lengths of 1, 1.2 and 1.5m. In this experiment an inverted U-shaped frame designed to support a spray sprinkler at different heights was used. The hydraulic installation with manual throttle valves for controlling water distribution was used to supply pressurized water to the spray model sprinkler. A number of 64 graduated catch-cans with 0.16 m diameter and 0.2m height were used. The cans were arranged in eight radial legs with a distance of 1m apart. The system was run for one hour then the caught volumes were measured manually using a graduated cylinder with a capacity of 500 mL. The catch-cans data were used to determine uniformity coefficients. Line graphs were used to show relationships between the parameters measured. The experiment shows that there is strong relationship between the parameters considered. It indicated that the coefficient of uniformity (CU) and distribution uniformity of lower quarter DUlq increases with increase in nozzle size and pressure. It also shows that the largest nozzle size and pressure within the limits of this experiment gave the best CU and (DUlq) values of 96% and 90% at 1.5m height. Lager nozzle sizes with lower pressure reduces the CU and DUlq values. It is concluded from this experiment that though pressure, nozzle size and height of application influences the uniformity of application, larger nozzle sizes accompanied by higher pressure and height of application resulted in good uniformity of application. It is therefore imperative that while operating Pivot Sprinkler systems, careful selection of nozzle diameters, operating pressure and drop tube heights, sprinkler can be used to apply the ideal amount of irrigation water needed to refill the crop root zone that can neither cause runoff nor harm the crop and also provide the best uniformity possible under the prevailing wind and management conditions.
