Abstract

Acidity is still a serious obstacle for maize cultivation due to the very low availability of phosphorus. The use of phosphate biofertilizers, containing phosphate solubilizing bacteria as an active ingredient, together with organic ameliorants was expected to be able to provide phosphorus for plants, increase the organic C content in the soil. Experiment aimed to find the proper application of phosphate biofertilizers along with organic ameliorants to support the growth and yield of maize on acid soils. The experiment used a factorial randomized block design with phosphate biofertilizers and organic ameliorants as the first factor and doses of P fertilizer as the second factor, which was repeated three times. Results showed that the application of phosphate bifertilizers consisted of Enterobacter ludwigii + Bulkholderia vietnamiensis + Citrobacter amalonaticus were applied together with organic ameliorants with the composition of chicken manure compost (25%): municipal waste compost (25%): coconut shell biochar (50%) at a dose of 5 tons/ha was able to increase plant dry weight and dry weight of shells per hectare by 248.87 g and 12.960 kg. The C-organic content of the soil had no significant effect due to the application of phosphate biofertilizers and organic ameliorants. The application of phosphate biofertilizers and organic ameliorants can support the growth and yield of corn plants on acid soils.

Abstract

Utilization of saline land as an effort to increase rice productivity is still constrained by the adverse effects of salinity stress. The solution to this effort can be done by utilizing PGPR biofertilizers and applying ameliorant briquettes. The purpose of this study was to evaluate the effect of using biofertilizers and ameliorant briquettes on saline soils with various levels of salinity on the growth of rice plants. This research was conducted at the Ciparanje Jatinangor screen house from September 2022 to January 2023. The research design used was a randomized block design with 12 treatments and 3 replications. The treatment applied was PGPR biofertilizer, ameliorant briquettes, and their combination on saline soil 4 and 8 dS m-1 compared to control (non-saline soil). The results showed that PGPR biofertilizer increased the height of rice plants on saline soils 4 and 8 dS m-1 7 DAP. At 14 DAP, PGPR biofertilizer, ameliorant briquettes, and their combinations did not increase rice plant height, root length and volume, wet weight, and dry weight of rice plants, although the application of biofertilizers, ameliorant briquettes, and their combinations tended to increase wet weight and dry weight of rice plant compared to soil with the same salinity without biofertilizers and ameliorant briquettes.
