Abstract

Inceptisols are the main agricultural soils in Indonesia. However, Inceptisols have problems such as relatively low soil fertility, due to weathering and leaching. Increased fertilization efficiency can be achieved through the use of biological fertilizers, in the form of microbial consortium and arbuscular mycorrhiza. Maize plant can be used as an indicator of soil fertility because it is very responsive to nutrient treatments. The study aimed to determine the effect of microbial consortium and Arbuscular mycorrhizal (MA) biofertilizers on the growth of corn plants on Inceptisols. The application of microbial consortium and Arbuscular mycorrhizal (MA) biofertilizer was able to increased plant height at 6 WAP (Week After Planting) by 42% and 8 WAP by 34%, root length by 142%, number of spores by 216%, mycorrhizae colonies on the root by 60%, total population of bacteria by 248%, soil pH by 5,5%, available P by 29%, and C-organic by 49%. The effective dose of microbial consortium fertilizer to increase the growth of maize plants was 0.8 g polybag-1 (M2).

Abstract

The distribution of very abundant AM in UB forest is very potential to be used as biological fertilizer. Biofertilizer production through the utilization of AM spores requires the multiplication of AM by using host plants namely maize (Zea mays L.), soybean (Glycine max (L) Merill) and tithonia (Tithonia diversifolia) and planting media consisting of soil added with cattle manure and rock phosphate. This study aimed to obtain the best host plants and growing media in producing the number of AM spores and AM colonies so that they can be used as AM biological fertilizer production. The study design used was a factorial randomized group design with host plants (H) as the first factor and planting media (M) as the second factor consisting of 18 treatments with 3 replications. The multiplication results showed that media with an M5 dose (150 kg ha-1 rock phosphate + 5 t ha-1 cattle manure) was high in producing AM spores amounting to 324,67 AM 100 g soil-1 in maize and 61.11% AM colonies in soybeans. Rock phosphate and cattle manure were sources of P in the growing media and AM which was multiplied to carry out its activities in producing phosphatase enzymes to produce P available for plants. Maize and soybeans had stable growth, good rooting, fast plant growth and low root lignin content which made it easy for AM to make colonies.
