In the master’s thesis, we investigated the efficiency of onion irrigation using drip irrigation and micro-sprinklers on two experimental fields. We independently determined the optimal timing and amount of irrigation based on soil moisture content and the plant's phenological stage, considering all previously mentioned factors. The experiment was conducted by irrigating part of the field while leaving another part unirrigated. The results indicate that drip irrigation achieves similar yields to micro-sprinklers but with lower water consumption. The analysis showed that drip irrigation utilizes water resources more effectively, which is crucial in times of climate change and increased pressure on limited water supplies. By using precise soil moisture monitoring and digital tools to optimize irrigation, we achieved higher onion production efficiency, contributing to the sustainable use of natural resources. In addition to comparing irrigation methods, the research contributes to understanding the impact of precise water management on onion yield quality and quantity. The study highlights the importance of modern digital tools in agriculture, enabling better irrigation control and adjustment of water supply based on plant needs and environmental conditions. The findings suggest that the use of drip irrigation, supported by informed decision-making, allows for more efficient water use and thus contributes to sustainability.
