Impact of the use of water from fish farming in the irrigation of pepper crops (Capsicum annuumL.) in the greenhouse in the Biskra region

ABSTRACT

The conservation of water and its rational management in crop irrigation is important for sustainable agriculture in arid and semi-arid regions, particularly with the appearance of the effects of climate change in these regions. The paper reports a study of the impact of using water from fish farming in the irrigation of pepper crops grown in greenhouses under salinity conditions. The results obtained show that the use of fish water in irrigation improves the vegetative growth of plants and their fruit yields. It also has a beneficial effect on the soil by increasing its level of organic matter, total Nitrogen and other nutrients. The value that this work adds is the conservation of the soil by improving its quality and the reduction of water pollution by reusing this wastewater in irrigation. The reduced use of synthetic fertilisers facilitates the application of organic farming. These advantages benefit the environment and consumers of the crops.
