ABSTRACT

The study investigates the impact of Spirulina platensis, a nutrient-rich cyanobacterium, on Vigna radiata (mung bean) seed germination and seedling growth. Our work assesses the influence of Spirulina platensis as a foliar spray and explores the effect of varying soaking durations (1hr, 2hr, 3hr, 4hr, and 5hr) on seed germination. In addition, foliar spray treatments with Spirulina extract are administered, with control groups receiving only water treatments. The experiment results and analyzes data on germination rates, seedling vigor, growth parameters, and physiological responses. Surprisingly, results show a slightly significant impact on seed germination and seedling growth regardless of Spirulina concentration. Notably, a soaking duration of 4hrs significantly enhances seed germination in Vigna radiata compared to other durations. These findings confirm Spirulina platensis as an effective bio stimulant, with its bioactive compounds accelerating the germination process. The study suggests the potential utility of Spirulina platensis in agriculture, presenting opportunities for sustainable practices and improved crop production.
