PHÂN BÓN LÁ OLIGOCARRAGEENAN TỪ RONG SỤN – CÁC TÁC ĐỘNG ĐẾN SINH TRƯỞNG VÀ NĂNG SUẤT CÂY TRỒNG

Tóm tắt

This study presented the results of an investigation into the effects of carbohydrate concentrations in foliar
fertilizer TN06-1 on the growth, performance, yield components, and overall productivity of maize and
coffee plants. The biological compound - oligocarrageenan - used as a foliar fertilizer was derived from the
hydrolysis of Kappaphycus alvarezii algae through an enzymatic process utilizing Viscozyme L in
combination with ascorbic acid as an catalyst. Solutions containing oligocarrageenan (OCs) at varying
concentrations demonstrated differential impacts on plant growth and yield parameters. Specifically, a
concentration of 100 ppm yielded the most favorable results for plant height, ear kernel number, and yield in
maize. Conversely, for coffee plants, optimal yield and seed quality were achieved with OCs concentrations
of 150 or 200 ppm. Additionally, the findings indicated that the foliar fertilizer formulation containing
oligocarrageenan exerted a direct positive influence on plant health and development, as evidenced by
improved nutritional balance, enhanced root system development, and increased resilience to environmental
stress, ultimately leading to higher crop quality
