Research on Plant Growth of Genotypes of Arabica Coffee on Water Stress

Due to the changing global environment, a drought-tolerant genotype must be developed. The parental environment may have an impact on the performance of Arabica coffee offspring. Arabica coffee was grown throughout a wide variety of elevations, precipitation, and temperature in Indonesia’s North Sumatra province. As a result, a drought-tolerant genotype may be present in this coffee farm. The goal of this study was to see how water stress affected the performance of Arabica coffee genotypes. We employed seven genotypes from seven different habitats, as well as four different levels of water treatments (100 percent, 75 percent, 50 percent, and 25% field capacity). Plant height, stem diameter, and leaf number were all increased by paramaters. The green house was used to conduct a factororial experiment, which included a totally block design with two factors and three replications. The interaction between genotype and water treatment level was shown to be significantly significant. It could be inferred that selecting for drought tolerance genotypes from the existing Arabica coffee population is a viable option. Due to the substantial GxE interaction, selection should be done in a controlled environment.
