Abstract
In regions with limited water resources, such as North Sinai, this study compares the effects of smart irrigation systems (SIS) and traditional irrigation techniques (TIT) on the productivity and quality of bell pepper (Capsicum annuum L.) in greenhouses. The study aims to evaluate the impact of SIS on bell pepper growth, fruit yield, and quality compared to TIT, as well as to determine the optimal irrigation depth for maximizing productivity and quality..
The study was conducted over two seasons (2023-2024 and 2024-2025) at the Faculty of Environmental Agricultural Sciences farm, El-Arish University. A split-plot design was used, with SIS and TIT as main treatments and four irrigation depths (surface drip at 0 cm and subsurface drip at 10 cm, 20 cm, and 30 cm) as sub-treatments.
SIS outperformed TIT in terms of fruit number, weight, and overall yield. The highest fruit weight was observed at the 10 cm depth (D10), while the lowest was at 30 cm (D30), with values of 8.33 kg/m² and 5.75 kg/m², respectively. SIS also improved fruit quality, plant height (62 cm), stem dry weight (17.11 g), and leaf number (110.1 per plant), particularly at D10. Deeper irrigation depths (D20 and D30) negatively affected plant performance.
SIS demonstrated a significant improvement in crop yield (5.83 kg/m²) and fruit quality in greenhouse bell pepper cultivation. The study suggests that SIS, especially at shallower irrigation depths, provides a promising and sustainable solution for agriculture in arid and semi-arid regions like North Sinai.
