Abstract

One of the important food crops in Gorontalo is corn (Zea mays L. var. ceratina), and root health is very important in determining its growth and productivity. This study aims to determine the root shoot-root ratio and root infection of waxy corn plants given arbuscular mycorrhizal fungi as biostimulants. This study was conducted from July to December 2025 using a completely randomized block design (RBD) with four different doses mycorrhizal arbuscular: 0, 10, 20, 30 g /polybag, which were replicated three times and observed periodically over 42 days after planting (DAP). The variables observed were root shoot-root ratio and root infection of plants at 14, 21, 28, 35, and 42 days after planting. The results showed that the application of mycorrhizae with different doses resulted in a root shoot ratio that increased in line with the increasing age of the plant. In contrast, it was interesting to find that in plant root infections, mycorrhizal application appeared to increase until the plants were 28 days after planting, after which it declined. This finding suggests that arbuscular mycorrhizal inoculation given to plants at different doses can impact root health, as indicated by the ratio of root decay to root infection. The symbiosis between mycorrhizae and plants is crucial for the growth of waxy corn.

Abstract

Waxy corn (Zea mays var. ceratina) is an important food crop whose growth and productivity are strongly influenced by nutrient availability and soil microbial activity. The use of Actinomycetes as a biological biostimulant has gained attention due to its potential to enhance plant growth in an environmentally sustainable manner. This study aimed to evaluate the response of waxy corn growth rate to different doses of Actinomycetes inoculation. The experiment was conducted from July to December 2025 using a Randomized Block Design (RBD) consisting of three treatments: without Actinomycetes application (PA0), 5 g Actinomycetes (PA1), and 10 g Actinomycetes (PA2), with three replications for each treatment. Plant growth observations were performed at 14, 21, 28, 35, and 42 days after planting (DAP). Growth rate was determined based on the increase in plant dry biomass over each observation interval. The results showed that Actinomycetes inoculation affected the growth rate of waxy corn. The PA2 treatment consistently exhibited higher and more stable growth rates compared with PA0 and PA1 throughout the observation period. The enhanced growth performance was likely associated with the role of Actinomycetes in improving nutrient availability and stimulating vegetative development. In conclusion, the application of 10 g Actinomycetes demonstrated the greatest potential to increase the growth rate of waxy corn and may serve as an effective biological biostimulant for sustainable crop production.
