As the human population rises, the demand for high nutritional foods, such as green vegetables, also increases. However, agricultural land, especially in urban areas, is increasingly narrowing. Hydroponics can be one of the solutions to answer this problem. In addition to complete nutrition, hydroponic plants also require appropriate media for root attachments, water absorption, and aeration. However, no studies have compared the growth of hydroponic plants using rockwool and sponge as affordable growing media. Therefore, this study aimed to determine the effect of local rockwool, imported rockwool, and sponge as growing media on the growth of spinach (Amaranthus sp.) and green lettuce (Lactuca sativa) using Deep Flow Technique (DFT). This study used a Completely Randomized Design with three treatment groups, i.e., three different growing media, for spinach and lettuce. At the harvest period, the number of leaves on each plant was counted, the crown fresh-weight was balanced, and the chlorophyll content was determined. Plant height was also measured for spinach. The results showed no significant differences in all observed parameters except for the crown fresh-weight of the lettuce. The crown fresh-weight of the lettuce grown on sponge media was found to be the lowest significantly (81.47 ± 9.50 g) among all treatment groups. Other hydroponic growing media’s influences can be investigated for further research, with additional growth parameters such as crown dry-weight, root fresh- and dry-weight, as well as the determination of plant phytochemical contents. Moreover, the composition of nutrients can also be further examined to reveal the type of growing media and nutritional formulations that are most optimum for hydroponic spinach and lettuce growth.

A. hypochondriacus leaves contained ample phytopigments including betalain, anthocyanin, β-xanthin, β-cyanin, and bioactive phytochemicals of interest in the industry of food. We have been evaluating the possibility of utilizing phytopigments of amaranth and bioactive constituents for making drinks. Therefore, we evaluated bioactive phytopigments and compounds including the potentiality of antioxidants in A. hypochondriacus leaves. A. hypochondriacus leaves have abundant protein, carbohydrates, and dietary fiber. We found considerable levels of inorganic minerals including magnesium, calcium, potassium (3.88, 3.01, 8.56 mg g−1), zinc, manganese, copper, iron (16.23, 15.51, 2.26, 20.57 µg g−1), chlorophyll b, chlorophyll ab chlorophyll a (271.08, 905.21, 636.87 μg g−1), scavenging capacity of radicals (DPPH, ABTS+) (33.46, 62.92 TEAC μg g−1 DW), total polyphenols (29.34 GAE μg g−1 FW), β-xanthin, betalain, β-cyanin (584.71, 1,121.93, 537.21 ng g−1), total flavonoids (170.97 RE μg g−1 DW), vitamin C, β-carotene, carotenoids (184.77, 82.34, 105.08 mg 100 g−1) in A. hypochondriacus leaves. The genotypes AHC6, AHC4, AHC11, AHC5, and AHC10 had a good scavenging capacity of radicals. Polyphenols, phytopigments, flavonoids, and β-carotene of A. hypochondriacus had potential antioxidant activity. Extracted juice of A. hypochondriacus can be an ample source of phytopigments and compounds for detoxification of reactive oxygen species (ROS) and attaining nutritional and antioxidant sufficiency.

We evaluated 17 genotypes of stem amaranth (Amaranthus lividus) in terms of dietary fiber, moisture, carbohydrates, fat, ash, gross energy, protein, minerals, phytopigments, total antioxidant capacity (TAC), vitamins, total flavonoids (TFC), total polyphenols (TPC) and their variations. Stem amaranth leaves have abundant dietary fiber, moisture, carbohydrates, and protein. We found significant amount of potassium, calcium, magnesium (9.61, 24.40, and 29.77 mg g −1 DW), iron, manganese, copper, zinc, (1131.98, 269.89, 25.03, and 1006.53 µg g −1 DW), phytopigments such as chlorophyll a, chlorophyll ab chlorophyll b, (27.76, 42.06, and 14.30 mg 100 g −1 FW), betalain, betaxanthin, betacyanin (62.92, 31.81, 31.12 µg 100 g −1 FW), total carotenoids, beta-carotene (1675.38, 1289.26 µg g −1 fW), vitamin c (1355.46 µg g −1 FW), TPC, TFC (228.63 GAE and 157.42 RE µg g −1 DW), and TAC (DPPH, ABTS +) (26.61, 51.73 TEAC µg g −1 DW) in the leaves of stem amaranth. Genotypes exhibited a wide range of variations. Three genotypes DS40, DS30, and DS26 could be used as an antioxidant profile enriched stem amaranth. Phenolics, phytopigments, flavonoids, and vitamins of stem amaranth leaves exhibited strong antioxidant activity. Stem amaranth could be a potential source of dietary fiber, moisture, carbohydrates, protein, minerals, phenolics, phytopigments, flavonoids, and vitamins in our daily diet for attaining nutritional and antioxidant sufficiency.
