Water Quality Effects on Germination of Okra Seed (Abelmoschus esculentus L.)
This study, conducted at Bakrajo Technical Institute in 2023, assessed the water quality of 24 resources using the Irrigation Water Quality Index (IWQI). Results revealed two categories: "Excellent" (19 resources, IWQI 91.4-96.5) and "Good" (5 resources, IWQI 70-90). Water in th...

| Summary: | This study, conducted at Bakrajo Technical Institute in 2023, assessed the water quality of 24 resources using the Irrigation Water Quality Index (IWQI). Results revealed two categories: "Excellent" (19 resources, IWQI 91.4-96.5) and "Good" (5 resources, IWQI 70-90). Water in the "Excellent" category was highly suitable for irrigation, while the "Good" category was of lower quality but still acceptable. Electrical conductivity (EC) was identified as a key factor influencing the IWQI, with higher EC correlating with lower water quality. Principal Component Analysis (PCA) and Agglomerative Hierarchical Clustering (AHC) were used to classify resources based on cation, anion, and heavy metal content. A negative correlation between EC and IWQI emphasized the importance of monitoring EC for irrigation purposes. The study also found weak, non-significant correlations between pH, EC, and germination ratio, but noted that higher IWQI values and lower EC levels generally promoted better seed germination. The findings highlight the value of advanced models in water quality classification, offering essential insights for agricultural water management.
