Development of automatic hydroorganic vegetable growing system

Abstract

Vegetable Growing System has an absolute requirement of nutrients and minerals. The microbial application can facilitate in addressing limited access to chemical fertilizer concerns. Moreover, the photosynthetic microorganism community can contribute together in nutrient availability for plant growth. This research aims to develop an automatic hydro-organic vegetable growing system. Moreover, the analytical of photosynthetic microorganism growth rate in fermented juice was also observed within three months in terms of temperature, pH, electroconductivity, total dissolved solids, mixed liquor suspended solids, and phosphorus. The efficiencies of an automatic hydro-organic vegetable growing system were also monitored along an experimental period (45 days of operation optimization). The vegetable growth rate was observed in terms of leaf length leaf width, and root length. These experimental results showed that the phototrophic growth of photosynthetic microorganisms should the main bacterial activity at daytime operation and vegetables could grow by using fermented juice. The photosynthetic microorganism concentration and nutrients concentration in fermented juice was significant to promote the productivity of vegetable growing which the photosynthetic biomass is rich in proteins and vitamins. Besides, this system can be easily applied and also very cost-effective for agricultural practice, and frequent maintenance every experimental run was necessary.
