The Effects of Soil Nutrient NPK Indicator and Recommendation System for Brassica Rapa subsp. Chinensis or Taiwan Pechay Bokchoy

Agricultural fertilization plays an important part in maintaining and increasing the yield capacity and growth of plants. Fertilizer application must be accompanied by the correct fertilizer recommendation. This study aims to develop a system that can measure the NPK contents of soil and provide fertilizer recommendations for Bok Choy and determine if there will be a significant difference in the plant's average leaf length and weight when compared to a method that uses a complete fertilizer application. Two different setups were done in the study to grow the plant. Setup A used fertilizer recommendations based on the system while Setup B used only complete fertilizer. Data shows that in terms of leaf length and weight, Setup A produces on average, longer leaves and heavier yields, respectively. However, based on the t-test analysis, both the p-value for the average length of leaves and weight were greater than the significance level, indicating that there was no significant difference in the results when using Setup A compared to Setup B. In conclusion, the use of an NPK recommendation and fertilizer recommendation system does not significantly affect the average length of leaves and weight of Bok Choy plant when compared with the use of a complete fertilizer setup.
