ABSTRACT
In this study investigating the “Impact of Copper Levels on Early Growth Stages of Kenaf and Mesta Cultivars at BJRI,” we observed significant treatment-specific effects on shoot length, root length, fresh weight, and dry weight of Kenaf and Mesta plants at 20 and 40 days after sowing (DAS). At 20 DAS, both Kenaf and Mesta exhibited decreasing trends in shoot length, with T3 showing the lowest values (Kenaf: 9.16, Mesta: 6.56) and T0 displaying the highest (Kenaf: 16.83, Mesta: 16). This suggests an inhibitory effect of copper, particularly in T3, on the early shoot development of both crops. As the growth progressed to 40 DAS, shoot length continued to decrease across all treatments, with T3 consistently lower than others, indicating a potential long-term inhibitory effect on shoot development. Additionally, T2 exhibited a notable impact on Kenaf shoot growth at 40 DAS. Root length showed treatment-specific effects, particularly in T2, with Kenaf exhibiting higher variability. Fresh weight and dry weight displayed complex responses, with T3 significantly influencing biomass accumulation. The observed trends underscore the need for further research to elucidate underlying mechanisms and assess long-term implications on the growth and performance of Kenaf and Mesta crops.
