Data obtained from survey results and field research investigated the dynamics of N, P, and K nutrient contents and status in multiple regions across Indonesia. The nutrient status was determined by analyzing collected soil samples to measure the contents of N, P, and K. The analysis explains the mean, minimum, and maximum N contents and Indonesia's P and K nutrient status of the tropical lowland rice fields. For the field trials, soil samples were taken from three locations to determine their physical and chemical characteristics. Fertilization recommendations are determined using a quadratic linear graph to illustrate the relationship between N, P, and K doses and rice yield. Data observed and analyzed were vegetative growth and rice yield, including plant height, number of tillers, dry grain weight (14% water content), dry straw weight, N nutrient uptake in grain, straw, and total N, and N, P, and K concentrations in soil, rice plant, and grain were also measured. The field trial employed a statistical analysis was performed using SPSS Statistics v27 (2020). Significant treatment effects indicated by ANOVA were further analyzed using Duncan's Multiple Range Test (DMRT).
