The experiment was carried out in one of the unheated plastic houses at the station affiliated with the College of Agriculture and Marshlands / University of Thi Qar, Al-Muhiyah area, during the winter season 2024-2025, using a split-split plot design, the averages of the treatments were compared according to the least significant difference (LSD) test at the probability level of 0.05. The experiment included three factors: the first factor: two varieties of cherry tomatoes, Wadi Star and Cherry, the second factor, three concentrations of Nano NPK (0, 2.5 and 5) g L-1 sprayed on the plant, and the third factor, three concentrations of fulvic acid (0, 2 and 4) g L-1 as a soil addition to the plant, with three replicates for each treatment. The aim was to determine the variety of cherry tomatoes that can be successfully grown in the conditions of Thi Qar Governorate and that has high productivity, as well as to determine the optimal concentration of both Nano NPK and fulvic acid in the physical characteristics of cherry tomato plants. The results showed superiority the cherry variety was superior to the Wadi star variety in the number of fruits per plant, length, weight and diameter of the fruit at averages of (272.9 fruits. plant⁻¹, 17.800 mm, 6.178 g and 17.450 mm) respectively, and the Nano NPK concentration of 5 g. L-1 was significantly superior in the number of fruits, length, weight and diameter of the fruit at averages of (294.8 fruits plant⁻¹, 18.280 mm, 6.356 g and 17.930 mm) respectively, while fulvic acid was significantly superior to the concentration of 4 g L-1 with the number of fruits, length, weight and diameter of the fruit (346.0 fruits.plant⁻¹ , 20.425 mm , 7.150 g and 20.075 mm) respectively, and the results of the statistical analysis showed that the two-way and three-way interactions between the study factors were also significant in the studied traits.
