ABSTRACT

Present-day world is constantly emerging with new technologies in the field of agriculture and hydroponics is amongst one such easily scalable and sustainable technique in the field of agriculture. In hydroponics, plants are grown by just immersing their roots in an aqueous nutrient solution without the usage of soil. Biofertilizers are already proved to be eco-friendly contributors to efficient agriculture that provide required micronutrients and macronutrients to the plants. In search of an economically viable, sustainable, and natural hydroponics system, experiments were conducted to check the effects of the phycocyanin-rich extract of Spirulina (PRES) and Spirulina residue as biofertilizers on the growth of plants like Vigna radiata and Cicer airetinum when grown hydroponically. Later, the hydroponically grown plants were tested for numerous growth parameters like leaf area, root length, shoot length chlorophyll content, dry weight, and fresh weight, and data obtained was then compared with control grown with bio compost. In brief, studies concluded that both the plants, showed the overall highest plant growth parameters in Spirulina residue hydroponics systems, higher in PRES, and the least in controls with bio compost system after a period of 20 days. Keywords: hydroponics, Spirulina, biofertilizer, Vigna radiata, Cicer airetinum
