<![CDATA[People's purchasing power for animal protein has decreased and has shifted to processed soy foods as one of the foods containing vegetable protein during the Covid-19 pandemic due to the economic recession. Soybeans are a source of high vegetable protein so they require a lot of Nitrogen (N). To fulfill the demand for soybeans, soybean cultivation can be carried out in acidic mineral soils with a low pH. Acidic mineral soil with a low pH causes it difficult for N nutrients to be available and the bacteria Bradyrhizobium sp. difficult to symbiosis with soybean plants. The aim of this study was to increase the growth and N uptake of soybean plants on acid mineral soils by inoculating Bradyrhizobium sp. and lime. The research was conducted in Jati Kesuma Village, Namorambe, Deli Serdang on a plot size 200 x 200 cm using a factorial randomized block design (RAK) with 2 factors. The first factor was the inoculating of Bradyrhizobium sp inoculants consisting of without inoculant; BGR 3 inoculant; and LP 3 inoculant. The second factor was liming consisting of without liming and liming with a dose of 1.06 kg/plot (pH 4.9 to 5.5). The results showed that Bradyrhizobium sp. BGR 3 inoculant tended to increase soybean plant height on acid mineral soil, but LP 3 inoculant was able to increase shoot root ratio and tended to increase N uptake 62.86% on acid mineral soil. The addition of lime was able to increase the growth of soybean plants on acidic mineral soil and increased N uptake 4.08%. The combination of LP 3 inoculant and without liming was able to increase shoot root ratio of soybean 133,33% on acid mineral soils.]]>
