Role of Ulothrix Prescott as a Biofertilizer on Growth of Tomato

The effects of Ulothrix cylindricum extract (UCE), an algal liquid fertilizer, on tomato (Solanum lycopersicum) seedlings were examined in an in vitro experiment conducted at the Institute of Botany, University of the Punjab, Lahore. NPK, 5%, 10%, and 15% UCE, as well as a control group, were applied to the seedlings. The others died, and only the control group sprouted. As the plants developed, a later pot experiment evaluated other morphological parameters. With respect to chlorophyll content (31.559 ± 1.049), sodium (92.467 ± 2.326), potassium (4293.3 ± 192.2), phosphorus (380.00 ± 10.97), nitrogen (4166.7 ± 111.3), magnesium (10.133 ± 1.187), calcium (0.249 ± 0.017), and iron, the 15% UCE group outperformed the control group, according to the results. There were notable variations between 15% UCE and the other treatments, with the control having the lowest quantities of these nutrients. In comparison to NPK (25.003 ± 1.056) and the control (11.070 ± 1.169), 15% UCE had a significantly greater chlorophyll content (31.559 ±1.049). Furthermore, the fruit vitamin C content was higher in the 15% UCE group (5.473 ± 0.408) than in the control. According to the biochemical analysis, greater UCE concentrations enhanced fruit quality, raised nutrient levels, and encouraged plant development without having an adverse effect on ecological balance. These findings imply that UCE may improve overall plant health and tomato yield.
