Abstract

Lentil (Lens culinaris Medik.) is an important leguminous crop widely cultivated in arid and semi-arid regions due to its nutritional and economic value. Efficient irrigation management is critical for optimizing growth and yield, particularly on meadow-alluvial soils with variable moisture retention. This study aimed to develop and evaluate optimal agro-technical irrigation regimes for lentil cultivation in the Bukhara region of Uzbekistan. A field experiment was conducted using four irrigation treatments based on soil moisture depletion levels: 60%, 70%, 80%, and 90% of field capacity (FC). Growth parameters, seed and biological yield, and water use efficiency (WUE) were measured. Results indicated that irrigation at 80% FC significantly enhanced plant height, number of branches, leaf area index, seed yield, and WUE compared to other treatments (p < 0.05). Both under-irrigation and over-irrigation negatively affected growth and resource use efficiency. The study demonstrates that moderate irrigation at 80% FC provides optimal conditions for lentil productivity and sustainable water management in arid environments.
