Effects of organic, mineral, and growth regulator-enhanced foliar fertilizers on the growth and yield   of bok choy (brassica chinensis l.)

Tóm tắt

The study aimed to evaluate the effects of various foliar fertilizers on the growth and yield of Bok choy (Brassica chinensis L.) under net house and field conditions at An Giang University. The experiment, which was designed using a randomized complete block design with four replications, focused on four different types of foliar fertilizers: Lactora (an organic foliar fertilizer derived from seaweed and fish), Silimax (a mineral-organic foliar fertilizer), Grow 16 N -16 P - 8 K (a mineral foliar fertilizer with added growth regulators), and Hi-Potassium C30 (an organic-mineral foliar fertilizer). The results from both experimental phases showed that the Lactora treatment produced the highest plant growth at 35 days after planting in terms of plant height (29.9 cm), leaf number (22.6 leaves), leaf blade length (17.8 cm), and leaf blade width (12.3 cm), as well as the greatest yield (34.2 t/ha in the field). These findings suggest that Lactora organic foliar fertilizer significantly enhances the growth and yield of Bok choy compared to the other treatments tested, making it a practical and effective option for improving Bok choy cultivation in diverse growing environments.
