Effect of spray intervals with different concentrations of nutrient solution (Agro leaf) on the growth of tomato plant Lycopersicum esculentum L

Abstract

In the fields of a farmer in Kirkuk governorate for the 2023-2024 growing season to study the effect of three spray concentrations of Agro leaf nutrient solution (Agro leaf). (50, 25 and 0 ppm) on total vegetative growth for three periods during the growing season after the appearance of 4-5 true leaves for the first spray and 15 days apart for the second and third sprays, respectively. The results showed that Agro leaf neutraliser had a significant effect on the vegetative growth of the plant as all concentrations of the neutraliser at the first and second sprays outperformed the control treatment significantly in leaf length, leaf width, number of leaves, floral branches and plant height (39, 22.2 and 16.73). (53), (22.2), (16.73), (5.26) and (29.03) respectively for the first spray, (43.4), (39.96), (11.96), (5.03) and (50.63) respectively for the second spray, (39.4), (33.83), (43.96), (17.96) and (88. 3) respectively for the third spray, and it is observed that by re-spraying, the production rates of the plant are increased, which confirms the positive role of the nutrient on the different plant qualities.
