The demand for chemical fertilizers in Bangladesh is increasing by the day. Seaweed
extracts are high in a variety of bioactive substances that can be used as a biostimulant as an
alternative to agricultural plants. To assess the impact of foliar spraying of red seaweed (Gracilaria
tenuistipitata var. liui) extracts at 5, 10, 15, 20 and 25% concentrationsin comparison to the control
condition (water spray only) and soil application of recommended doses of fertilizer (RDF) as
basal on growth, chlorophyll and yield of mungbean variety BU mug5, a pot experiment was
conducted at the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural
University (BSMRAU), Gazipur, Bangladesh during Kharif-1 season (March to May 2021).
Seven (7) treatments: T1 – Control (foliar spray using water), T2 – Recommended doses of
fertilizers (RDF) as basal, T3 – Foliar spray of 5% seaweed extracts, T4 – Foliar spray of 10%
seaweed extracts, T5 – Foliar spray of 15% seaweed extracts, T6 – Foliar spray of 20% seaweed
extracts and T7 – Foliar spray of 25% seaweed extracts were imposed following completely
randomized design (CRD) with three replications. The results revealed that seaweed liquid
fertilizer at 20% concentration increased leaf area, total dry matter and chlorophyll (SPAD value)
by 25.00, 40.21 and 9.11% over the control and 15.42, 8.27 and 2.08% compared to RDF,
respectively. Seed yield increased by 93.14% when compared to a control with 20% seaweed
foliar spray, and by 9.04%, when compared to RDF. Foliar application of 20% seaweed liquid
fertilizer performed best among the treatments in terms of mungbean growth and yield, according
to findings of the experiment. The results of this study suggest that red seaweed extracts from
Gracilaria tenuistipitata var. liui may be used as a fertilizer to reduce the chemical fertilizer to
boost mungbean yield.
