Abstract

Mycorrhizal bio-fertilizers can maintain land productivity and are environmentally friendly. This study aims to analyze the effect of mycorrhizal biofertilizer on the growth of shallots (Allium cepa var. Aggregatum) and to determine root infection and its effect on soil N, P, K levels. The experimental design used was a completely randomized design (CRD). The treatment of biological fertilizer testing is carried out based on the Regulation of the Minister of Agriculture No. 70 / Permentan / SR. 140/10/2011, consisting of 6 treatments (AF) as follows: A) control, B) standard fertilizers, C) mycorrhizal biological fertilizers, D) mycorrhizal biological fertilizers + 25% standard fertilizers, E) mycorrhizal biological fertilizers + 50% standard fertilizer, F) mycorrhizal biological fertilizer + 75% standard fertilizer. There were 5 replications so that 30 experimental units were obtained. Mycorrhizal bio-fertilizers can reduce the need for standard fertilizers (PS) to 25% to 50%. The combination of biological fertilizer of 2.5 g / plant with 50% PS produces the best plant height and biomass weight, but economically it is recommended to use 25% PS. The treatment applied to mycorrhizae had a very high root infection value, which was above 75%. The types of spores that were successfully associated were Acaulospora sp., Glomus etunicatum, and Glomus sp. The application of mycorrhizae resulted in an increased response of 14.91% for P-available Latosol, while for K-dd and N-total there was no significant effect.

Abstract

The demand for sweet corn increases over time. To increase sweet corn production, many farmers often use inorganic fertilizers excessively. Excessive use of inorganic fertilizers can have a negative impact on soils. One of the efforts that can be made to increase sweet corn production is the provision of biofertilizers, such as mycorrhizae. This study used a completely randomized design (CRD) with two factors. The first factor was the application of fertilizer with 7 levels of treatment, namely Control; NPK fertilizer + organic fertilizer; NPK fertilizer + organic fertilizer + 2.5 g mycorrhizal granules; NPK fertilizer + organic fertilizer + 5 g mycorrhizal granules; NPK fertilizer + organic fertilizer + 2.5 g mycorrhizal powder; NPK fertilizer + organic fertilizer + 5 g mycorrhizal powder; and NPK fertilizer + organic fertilizer + mycorrhizal powder (coating). The second factor was two different soils used as growing media, namely Regosol and Latosol from Dramaga. This study was carried out in five replications. The parameters observed were plant height, stem diameter, plant biomass, root colonization, soil available P, and total P in plants. The results showed that the application of mycorrhizal powder with coating techniques increased the growth of maize plants, the level of root colonization, the availability of soil phosphorus nutrients, and plant phosphorus uptake by the plants.
