Abstract

This study evaluates the efficacy of various foliar fertilizers on the growth and yield of the heat-tolerant cucumber variety TV108. The experimental design included six different foliar fertilizers and a control, with applications made weekly at a concentration of 1 mL per liter of water. Results showed that all foliar treatments significantly enhanced plant height compared to the control. Among these, Treatment T4 (ATONIK foliar fertilizer) demonstrated the most pronounced effect, achieving a main stem height of 216.57 cm by the 70th day, which was significantly higher than other treatments and the control. Treatment T4 also excelled in increasing stem diameter, with a final measurement of 1.48 cm, and in promoting both male and female flower formation. The fruit set rate was highest in Treatment T4, reaching 28.67% on day 56 and maintaining at 8.67% by day 70. This treatment also proved most effective in reducing the incidence of key diseases and pests, including powdery mildew, white mold, green worms, and yellow beetles. Regarding yield, Treatment T4 produced the highest individual fruit yield (2.32 kg/plant), actual yield (33.8 tons/ha), and theoretical yield (84.91 tons/ha). Additionally, it enhanced fruit quality, as indicated by the largest fruit length (15.22 cm), diameter (4.13 cm), and the highest Brix value (3.50%). These results substantiate that Treatment T4 is the most effective foliar fertilizer for enhancing both growth and quality of heat-tolerant cucumbers under experimental conditions.
