“…In biochemical analysis total protein content was showed slight variations in Cauliflower as hydroponically grown showed 2.09% and conventionally grown cauliflower showed 1.84%, as the roots being in direct contact with the nutrient solution, uptake of nitrogen is favoured accounting for more protein content in hydroponically grown conditions (Figure 1 and Figure 2). Increase in the yield of vegetables was seen in soilless culture [19]. The total protein content was 3.49% more in the hydroponically grown radishes, than in soil grown radishes and individually, the hydroponic tomatoes had 4.3% and soil grown tomatoes had 0.81%.…”

Hydroponic techniques have major advancements in the recent years compared to Conventional Systems. The flow pattern of fluid used in hydroponic system in a cultivation container affects the growth of plants. Vegetables such as Strawberry, Basil, Cauliflower, Tomato, Spinach and Radish saplings were grown in soil and soilless methods to compare the growth, yield and nutritional value. As for the conventional system, the plants were grown in soil and for hydroponic system Nutrient Film Technique, Deep Water Culture and Wick Systems were used to cultivate plants. On the completion of the growth of the plants, the samples were analysed in laboratory for biochemical analyses. The total yield of Strawberry was 46.5% and tomato with 42.05% in Hydroponics system compared to soil system, whereas in Biochemical analysis Cauliflower gave 10.02% higher results. Chlorophyll content in Basil was observed to be 0.15mg/g and Spinach with 0.04 mg/g which was different from other corresponding results. The commercially harvested root of radish showed a total growth of 22.4 cm in the hydroponic system. The root and shoot lengths had significantly better results in Hydroponic system. Nutritionally, there were not many differences in few aspects whereas the hydroponically grown plants had better qualitative results. It was evident by the obtained results that, the hydroponically grown plants had better results when compared to the plants that were grown conventionally and the fluid flow patterns could also affect the productivity in the hydroponics system.

Modern hydroponic substrates have contributed significantly to the popularity and progress of hydroponic cultivations worldwide, nevertheless, their development, transportation, and disposal often come at a significant environmental cost. Here we investigate the feasibility of partial to total replacement of conventional organic growing media constituents, such as cocodust (C), in a 20% perlite (P) and 80% cocodust substrate (hereafter control 8C), with compost from locally sourced grocery waste (W). For this purpose, four treatment mixtures were developed (6C:2W, 4C:4W, 2C:6W, 8W), with the grocery waste-compost fraction ranging from 20 to 80%, respectively (perlite constant at 20%). The new substrates were tested on hydroponic lettuce (Lactuca sativa var. Tanius) cultivation. During the 35-day experiment, lettuce physiology was evaluated using chlorophyll concentration [SPAD], chlorophyll fluorescence [Fv/Fm], number of leaves, and plant growth index. At harvest, the plant yield was evaluated using leaf area [cm2], leaf fresh and dry weight [g], as well as leaf firmness [g]. Results show that substrates with compost led to superior physiology and yield characteristics, with 8W inducing a significant increase in leaf area, chlorophyll concentration, dry weight, and firmness, by 11.6%, 5.4%, 19.8% and 12.8%, respectively, compared to the control treatment 8C. Results indicate that grocery waste-based compost is an excellent sustainable alternative for the soilless cultivation of lettuce. After its use in hydroponic cultivation, substrate material is safe to dispose of or be used as a soil amendment, thus contributing to a circular agro-food economy model.
