Sustainable Green Development: Water-Saving Irrigation Technologies

\nIn the context of global climate change and increasing demand for natural resources, sustainable development requires the introduction of innovative technologies that contribute to the conservation and rational use of water resources. This article aims to examine water-saving irrigation technologies. The efficiency of the sprinkler irrigation system is affected by the wind flow and evaporation. Therefore, the comparison of designed and measured values of discharge from a nozzle and throwing radius of three sprinklers for 6 pressured head were done. Experiment was conducted at Uchxoz district, Tashkent region, Uzbekistan with latitude 69.248903 and longitude 41.037240. The place is 2 ha and experiment were at wheat crop. Irrigation system has been taken from Chirchik river. Sprinkler system installed with 9 to 12 m distances connect with a soil condition and slope. Because of importance of natural conditions, especially wind drift and radiation connect with the evaporation, research was performed at these losses. Furthermore, the calculation of wind drift and evaporation losses based on the observed values was calculated. The measured values of the discharges were lower as the designed one in all cases from 71% to 83%. Furthermore, we can conclude that the smallest differences were observed during the experiment with highest radius with smallest pressure head. The real radius of wetter area was from 80% to 88% of the designed radius by producer. The results showed the need to use the higher number of sprinklers or higher pressure to irrigate the required area.\n
