THE EFFECTS OF MICRONUTRIENT FOLIAR FERTILIZERS ON CERTAIN PHYSIOLOGICAL TRAITS AND YIELD OF CHERRY TOMATO (LYCOPERSICUM ESCULENTUM MILLER.) GROWN IN THANH HOA PROVINCE, VIETNAM

Tóm tắt

This paper presents the research results on the effects of micronutrient foliar fertilizers on certain physiological traits and yield of cherry tomato variety grown under rain-sheltered conditions in Thanh Hoa province, Vietnam. The findings show that in experimental formulas such as F2 (Ev05 Humi pro), F3 (Hd 99), F4 (Etda Zinc), and F5 (Ac-Gaba-Cyto), cherry tomato plants exhibited better growth and development compared to the control (Formula 1). This was evident through indicators such as leaf chlorophyll content, photosynthetic intensity, total number of flowers per plant, effective flower ratio, number of fruits per plant, and average fruit weight. Different formulas of micronutrient foliar fertilizers resulted in varying yields, with F5 (Ac-Gaba-Cyto) producing the highest yield at 36.53 tons/ha, followed by F2 (Ev05 Humi pro) with 35.24 tons/ha. F3 and F4 (Hd 99 and Etda Zinc, respectively) also yielded higher than the control (31.57 tons/ha), though not as high as F5 and F2.
