Introduction

The need for soybeans continues to increase along with the increase in population so that the increase in domestic soybean production needs special attention. One of the efforts is the development of soybean varieties with high yield potential. The purpose of this study was to determine growth and yield performance of four soybean varieties in rainfed lowland areas in Maros Regency. The study was carried out in Toddo Malie Village, Tompobulu District, Maros Regency from January to August 2020. The study used a Randomized Block Design (RAK) consisting of four treatments of soybean varieties (Biosoy 1, Biosoy 2, Detap 1, Dena 1) and five replications on farmer cooperator. The results of the study indicated that growth, yield components and yields were significantly different in the four adapted varieties of soybeans. The highest soybean yields were obtained from Biosoy 2 (1,191 kg / ha), followed by Biosoy 1 (1,158 t / ha), Dena 1 (912 kg / ha) and Detap 1 (778 kg / ha) varieties.
