This study aims to examine the intensity of Rust Disease (Phakopsora pachyrhhizi) and the resistance of soybean varieties (Glycine max (L.) Merrill) to crop yields. This study uses a Random Group Design (RAK) consisting of four varieties of soybeans, namely Wilis, Malabar, Ringgit and Dega-1. With 4 replicates and each replicate 5 plant samples were taken. The basic fertilizer used in accordance with the technical instructions of the national soybean consortium is 75 kg ZA + 100 kg SP36 + 75 kg KCl/ha + 5 tons of manure/ha. The observation data was analyzed using Analysis of Variance (F test). If the results show a real influence, the Smallest Real Difference (BNT) test of 5% will be continued. The study showed that the intensity of leaf rust attack and soybean resistance resulted in a dry weight of 19.70 g of Ringgit varieties, 18.05 g of Wilis, 17.05 g higher than that of the Dega-1 variety which weighed 6.25 g.
