    Effect of deficit irrigation with saline water on the moisture and salt regime of the soil
    Balaout, Ibtissem; Juhász, Csaba; DE--Mezőgazdaság- Élelmiszertudományi és Környezetgazdálkodási Kar
    Karcag region, our study area, is characterized by the widespread horticultural activities in hobby gardens all around the town using saline water, which caused secondary salinization for a long time. This phenomenon is threatening soil fertility, thus its function, causing a reduction in agricultural production. In the other hand, freshwater resource suffers from scarcity, and meanwhile, due to the increase of the population growth, intensive agricultural practices using irrigation technique, have become urgent to supply the population with their needs. However, these practices consist mainly of using saline water despite its negative effects in promoting secondary salinization. Through this research work, we proposed the use of deficit irrigation strategy (DI), a new strategy having the potential to optimize water productivity in horticulture. Another part related to this work involved the monitoring of the groundwater quality of the area on the base of monthly water sampling.

    Soil salinisation is considered one of the major environmental hazards threatening agricultural productivity and can be accentuated by climate change as well as the use of low-quality water in irrigation. This is the case in our study area which is affected by secondary salinisation due to the use of saline irrigation water for horticultural production. Deficit irrigation technique is implemented especially in arid and semiarid regions due to its potential to optimise water productivity while maintaining or increasing crop yield. The main objective of this study was to compare the effect of irrigation with sufficient (SD) and deficit (DD) doses. This research was carried out in Karcag in 2020. Cucumber was grown on a meadow chernozem soil and was irrigated with SD and DD of two irrigation water qualities. Soil moisture was monitored and crop yields were recorded. Despite the differences in quality and quantity of water, the application of less water by DD maintained the same yield as SD. We found a non-significant difference between the average soil moisture contents under the treatments (15.5 v/v% for SD and 13.5 v/v% for DD). Deficit irrigation can be an efficient technique due to its potential for improving water use efficiency, maintaining sufficient soil moisture content favourable for proper crop development and yield.
