Description
The project evaluates the application of oxygen fertigation with hydrogen peroxide in 'Fino 49' lemon trees under subsurface irrigation to improve root oxygenation and crop development. It aims to optimize water use and ensure fruit quality.
Contextual description
Under no-till conditions and with subsurface drip irrigation, promote soil aeration by applying hydrogen peroxide (H2O2), avoiding hypoxic conditions. The aim is to increase the earliness and overall productivity of the early 'fine' variety of lemon.
Results
The continuous application of H2O2 resulted in a significant increase in the oxygen content of the irrigation water. From a physiological standpoint, this higher O2 content led to a significant improvement in the crop's water status and gas exchange parameters. This physiological improvement did not translate into earlier harvests. Instead, there was a tendency to increase the total yield due to a greater number of fruits harvested. This resulted in improved water use efficiency.
