Arbuscular Mycorrhizal (AM) is a fungus that plays a vital part in symbiosis with plant roots and enhances the plant growth and productivity. The ubiquity of AM escalates the uptake of nutrient soil and environmental stress tolerance. A. E. Mau and S. R. Utami, 2014 reported that, “The presence of AM can increase the availability of nutrients especially phosphate”.
Formulation of arbuscular mycorrhizal with cow dung is requisite for crop cultivation system. As cow dung comprises of micro and macronutrients which are necessary for plants. Cow dung has the ability to fix physical dan biological soil and also plays a significant role in improving soil fertility.
Organic manures and fertilizers are considered as the potential source of plant nutrients for sustainable crop production. Huang et al. (2017) enlisted the chemical characteristics of the cattle dung that are as follow: pH 7.86, N 28.7 g kg–1, C/N 10.7, NH4+ 0.02 g kg–1, NO3– 0.7 g kg–1. Zaman et al. 2017 proclaimed that application of cow dung increases the total nitrogen (N), available phosphorous (P), exchangeable potassium (K), calcium (Ca), magnesium (Mg), available sulphur (S), zinc (Zn) and boron (B) contents in soils and biomass yield of plant.
Bladygrass, technically known as Imperatacylindrica classified as weed that has a wide range of hosts. Bladygrass primarily grows on marginal dry land can be used as an indigenous inoculum source of arbuscular mycorrhiza. This weed has various advantages like helping plants absorb nutrients and water moreover; it has the ability of adapting to any type of soil and inclement climate.
Hasid et al. (2021) conducted a study in order to find out the effect of various arbuscular mycorrhizal formulations with cow dung to phosphorus uptake, growth and yield of local corn (Zea mays L.) plant in marginal land. This research was carried out in 2018 in The Field Laboratory and Agrotechnology Laboratory of the Faculty of Agriculture, Halu Oleo University, Kendari, Southeast Sulawesi, Indonesia. Randomized Block Design (RBD) was used for this study in three groups with a single factor pattern, by using arbuscular mycorrhizal and cow dung treatments.
The results of this study exhibited that formulation of arbuscular mycorrhizal with cow dung showed significant results by increasing available Phosphorus, Phosphorus uptake, growth and yield of plant. Samanhudi et al. (2017) stated that treatments with mycorrhiza gave good results and significantly improve yields of plant as compared to the plants without mycorrhizal treatment.
In summation, the best treatment was obtained by using 50 g arbuscular mycorrhizal plus 80 g cow dung per planting hole equally with 5 t ha–1. While on the other hand, plants without arbuscular mycorrhizal inoculation and without organic fertilizer cow dung did not produce seeds.
