Background: Biogenic elements such as nitrogen (N), phosphorus (P), and potassium (K) are major pollutants of Lake Sevan's water, causing eutrophication and deterioration of water quality. Untreated wastewater, sewage, agriculture, fish farming, and other activities are significant sources of these pollutants. Vegetable cultivation, heavily reliant on mineral fertilizers and chemicals, and livestock breeding contribute substantially to nitrogen pollution in the lake. However, improved vegetable growing practices, including small-scale agriculture using organic fertilizers, natural soil improvers, and eco-friendly bio-liquids as growth stimulants, can enhance the socio-economic conditions for farmers in the Lake Sevan basin. These practices promote environmentally friendly, water-saving land-use methods, reducing nitrogen leaching into the lake.
Objective: This study aims to demonstrate the socio-economic and environmental benefits of applying innovative agro-technology to small-scale farming in the Lake Sevan watershed (Gegharkunik region). Specifically, the study objectives are to determine the quality characteristics of crops grown in small-scale farms and compare these quality indicators between yields obtained through the proposed technology and traditional cultivation methods.
Methods: Field trials of multi-crop systems were conducted on 0.25 ha land plots in four variations across four different locations in the Lake Sevan watershed. The trials were evaluated for various parameters. Nitrate content, dry matter, starch, vitamin C, and sugar levels were determined in potatoes, cabbage, broccoli, beets, and green beans, while fat content was measured in green beans and green peas.
Results: Economic efficiency calculations revealed that utilizing the proposed innovative agro-technology in a multi-crop small-scale farm (0.25 ha) yielded a 20-25% increase compared to traditional cultivation with synthetic fertilizers, accompanied by notable environmental benefits.
Conclusions: The study demonstrates that small-scale agricultural practices employing the proposed agro-technology have significant socioeconomic and environmental impacts on local farmers.
Keywords: Cultivation of non-traditional crops, organic farming, small-scale farming, activities, economic and ecological evaluation, and food quality characteristics.
