| Summary: | Tidal swampland is potential but negligible land characterized by poor soil fertility. The study aimed to determine the effect of fertilization packages on the growth and yield of Inpara 2 rice in the tidal field. This research was conducted on the tidal field of Mon Mata Village, Krueng Sabee Sub District, Aceh Jaya, from July to November 2018. The study was designed in a Randomized Block Design three treatments, and three plot replications of 10 m x 10 m. The treatments comprised of three fertilization packages, namely: Farmer’s package A (Urea 100 kg ha–1 + SP 36 50 kg ha–1); Package soil nutrient status B (Urea 200 kg ha–1 + SP36 100 kg ha–1 + KCl 50 kg ha–1), and Recommended package C (Urea 200 kg ha–1 + SP36 100 kg ha–1 + KCl 100 kg ha–1 + 1000 kg dolomite ha–1). The experiment showed that all three fertilization packages significantly impacted plant height, panicle length, number of panicles per hill, grain per panicle, and grain yield. The recommended fertilization package C gave the highest yield (5.20 t ha–1), followed by Package B (4.78 t ha–1) and Package A (3.55 t ha–1). The research suggests that Inpara 2 rice and fertilizers, according to the recommendations, are needed to increase rice productivity in tidal fields.
