Pineapple (Ananas comosus) is a popular fruit crop in Indonesia. Pineapple crowns are one of the planting materials used in pineapple cultivation; however, their growth is slower than that of other planting materials. Therefore, the addition of chitosan is necessary, as it has the potential to stimulate growth. This study aims to determine the best concentration and application time of chitosan that can improve pineapple growth. The study was conducted in the screenhouse of the Faculty of Agriculture, Sebelas Maret University, Surakarta, during March-June 2025 with a Completely Randomized Design (CRD) with two factors, namely chitosan concentration (without chitosan, 1 ppm, 3 ppm, 5 ppm) and time of chitosan application (morning, afternoon, morning and afternoon). Each treatment was repeated 4 times, resulting in 48 experimental units. The results showed that no combination of concentration and time of chitosan application was found to increase pineapple growth simultaneously. The treatment concentrations of 1 ppm and 3 ppm yielded the best results for increasing leaf number. Concentrations of 1 ppm, 3 ppm, and 5 ppm showed the best results for increasing total leaf area and the most extended root length. The time of chitosan application, once in the morning or evening, increased the photosynthesis rate and stomatal conductance. Chitosan has the potential to serve as a biostimulant for plant growth, enhancing the physiological activity of plants.

The research findings indicate that no specific combination of chitosan concentration and application time demonstrably enhances pineapple growth.However, applying chitosan at concentrations of 1 ppm and 3 ppm effectively increases leaf number, while concentrations of 1 ppm, 3 ppm, and 5 ppm promote greater total leaf area and root length.Furthermore, applying chitosan once in the morning or evening can improve photosynthesis rate and stomatal conductance.Therefore, a concentration of 1 ppm and morning chitosan application are recommended for pineapple cultivation to optimize growth parameters.

Penelitian lebih lanjut perlu dilakukan untuk mengeksplorasi pengaruh chitosan pada fase reproduksi tanaman nanas, termasuk pembentukan bunga dan buah, serta dampaknya terhadap kualitas pasca panen. Selain itu, studi komparatif antara berbagai sumber chitosan, seperti dari kulit udang dengan sumber lainnya, dapat dilakukan untuk mengidentifikasi sumber chitosan yang paling efektif dalam meningkatkan pertumbuhan nanas. Terakhir, penelitian mengenai interaksi antara chitosan dengan mikroorganisme tanah yang menguntungkan, seperti mikoriza atau bakteri penambat nitrogen, dapat membuka peluang untuk mengembangkan strategi pemupukan yang lebih berkelanjutan dan meningkatkan efisiensi penyerapan nutrisi oleh tanaman nanas, sehingga menghasilkan pertumbuhan yang lebih optimal dan hasil panen yang lebih tinggi. Penelitian-penelitian ini diharapkan dapat memberikan pemahaman yang lebih komprehensif tentang potensi chitosan sebagai biostimulan dalam budidaya nanas dan berkontribusi pada pengembangan praktik pertanian yang lebih efisien dan ramah lingkungan.
