Peningkatan Produktivitas Kedelai (Glycine Max (L.) Merrill) Pada Tanah Podsolik Dengan Fungi Mikoriza Arbuskular Dan Zeolit Sintetis Dari Abu Terbang Sebagai Pembenah Tanah
Soybean is one of the most popular agricultural commodities in Indonesia, but soybean
production in Riau is still low, therefore it is necessary to make efforts to extend
agriculture in the form of developing marginal land. This study aims to study and
determine the interaction of Arbuscular Mycorrhizal Fungi (AMF) and coal fly ash (FA)
zeolite and the main effect of each of these treatments on soybean productivity in
Podzolic soils. This research is an experiment using a completely randomized design with
two factors. The first factor was the dosage of zeolite FA which consisted of 4 levels,
namely Z0 (without zeolite), Z1 (0.5 g/plant), Z2 (1 g/plant) and Z3 (1.5 g/plant). The
second factor was the dose of AMF which consisted of three levels, namely M0 (without
AMF), M1 (AMF Glomus sp 10 g/plant) and M2 (AMF Gigaspora sp 10 g/plant). The
results showed that the interaction of AMF Glomus sp or Gigaspora sp each 10 g per
plant with zeolite FA at a dose of 1.5 g/plant increased root development (number of
effective root nodules, total number of root nodules, nutrient uptake of N, P, K), growth
plants (plant height, number of productive branches, flowering age, harvesting age) and
yields of soybean plants (number of seeds/plant, seed weight/plant) were the highest
compared to no treatment and other combinations, but the FA zeolite dose of 1 g/plant
was able increased soybean yield at 100 seed weight and protein content. The main effect
of each treatment was able to increase root development, growth and yield of soybean
plants in podzolic soil.
