Role of Albitbr bio-stimulant application on growth, yield and quality characteristics of tomato (Lycopersicon esculentum) cultivars under open field conditions

Climate change coupled with the indiscriminate use of inorganic fertilizers and pesticides are causing tremendous challenges on the production potentials of crops and also health of the people of the world. As part of the sustainable production strategy, the current study was conducted at the experimental station Vniccok, Russia during summer of 2024 using a bio-stimulant “Albitbr on tomato crop. In the experiment, four different cultivars were treated with seven different doses of the bio-stimulant (control, 0.1, 0.5, 1, 2.5, 5, 10 and 50 L/ha). The highest significant leaf area (115.23 cm2 ) and yield of tomato fruits (83.35 t/ha) were obtained from Fenaric and Malets cultivars, respectively. Application of the bio-stimulant also resulted in a significant effect on leaf area, total yield, titratable acidity (TA) as well as total soluble solids (TSS)/TA with the highest leaf area (119.88 cm2 ), total yield (78.81 t/ha) being produced from the bio-stimulant dose of 2.5 L/ha, whereas the highest values of TA (0.28 %) and TSS/TA (21.72) were obtained from 0.1 L/ha and 50 L/ha, respectively. © 2024, Gaurav Publications.
