This study evaluates the growth and production of sweet corn plants using various doses of nitrogen-phosphorus (NP) fertilizer tablets in combination with potassium chloride (KCl) fertilizer. The research was conducted from October 2022 to January 2023 at the Research and Development Luas Birus Utama and Syngenta Indonesia Cikampek Station in Karawang, Indonesia. A factorial randomized block design with two treatment factors was employed: five types of NP fertilizer tablets (0%, 0.81%, 1.57%, 2.33%, and 3.06% nitrogen) and standard NPK fertilizer (15% N, 15% P, and 15% K). The results showed that NP fertilizer tablets, when combined with KCl, did not significantly differ from NPK fertilizer in terms of plant growth, biomass, and yield components. Soil tests before and after application indicated that NP fertilizer tablets effectively enhanced nutrient absorption by plants. The study concludes that small-scale green ammonia production technology, combined with NP fertilizer tablet manufacturing using local phosphate, can be a suitable solution for meeting the fertilizer needs of rural communities in Indonesia. This approach is cost-effective, low-carbon, and energy-efficient, contributing to food security and sustainable development goals.This study evaluates the growth and production of sweet corn plants using various doses of nitrogen-phosphorus (NP) fertilizer tablets in combination with potassium chloride (KCl) fertilizer.
