The aim of this study was to determine the potential biomass yield increase by the change created in plant architecture by cutting the top shoot of soybean. In the research, Arisoy and Lider soybean varieties, which are widely cultivated in Cukurova Region, were used as materials. In the research, plants top shoots were pruned during three-leaf (3B) and five-leaf (5B) stages. In the study, the seed yield per decare in the Arisoy variety was 461 kg in the control group, 440 kg in 3B application and 553 kg in 5B application. These values were realized as 540, 478 and 519 kg in the Leader variety, respectively. As a result of the research, while the seed yield was highest in the 5B application of the Arisoy variety, the Leader variety responded negatively to two different applications ( 3B and 5B). This situation revealed that pruning mechanization, which will develop suitable plant architecture for high seed and biomass yield in 5B period in Arisoy variety in our region, is applicable.
