Tujuan penelitian adalah untuk mengkaji peran mikoriza dalam meningkatkan laju pertumbuhan relatif dan laju asimilasi bersih tanaman padi pada berbagai kadar air tanah yang berbeda. Percobaan dilakukan di dalam green house dan bertempat di Kabupaten Mempawah Kalimantan Barat dari bulan Februari-Mei 2022. Percobaan disusun menggunakan rancangan petak terbagi (splitplot), petak utama adalah perlakuan mikoriza dengan 2 taraf (tanpa mikoriza dan menggunakan mikoriza) serta anak petak adalah pengaturan ketersediaan kadar air tanah dengan 3 taraf (60%, 80%, dan 100%), setiap kombinasi perlakuan diulang sebanyak 3 kali. Hasil penelitian diperoleh bahwa pengaplikasian mikoriza pada kadar air tanah 60%, 80%, dan 100% berperan dalam mempengaruhi laju pertumbuhan relatif dan laju asimilasi bersih tanaman padi. Selanjutnya penerapan mikoriza pada kadar air tanah hingga 60% tersedia mampu meningkatkan laju pertumbuhan relatif dan laju asimilasi bersih tanaman padi yang sama baiknya dengan kadar air tanah 100% tersedia, sedangkan pada tanaman padi tanpa mikoriza dan kadar air tanah 60% dan 80% diperoleh nilai laju pertumbuhan relatif dan laju asimilasi bersih yang sangat rendah.

The growth and yield of rice in limited soil water are expected to increase through the application of mycorrhizae due to the increasing root ability to absorb water and nutrients from the soil. The study aimed to determine the role of mycorrhizae on the growth and yield of rice plants in different soil water content. The study was conducted in Mempawah District, West Kalimantan, in February-June 2022. The experiment was arranged in a split-plot randomized complete block design with main plots of mycorrhizae treatment on seedlings (without and with mycorrhizae application), and subplots of soil water content (100%, 80%, 60%). The results showed that mycorrhizae could colonize 60-80% of roots and increase phosphorus absorption at up to 60% of soil water content. Application of mycorrhizae improved plant growth up to 80% of soil water content for the maximum number of a tiller, and 60% of soil water content for the leaf area. Mycorrhizae performed better to increase yield at up to 80% soil water content on the number of productive tillers and grain index of 1,000 seeds, and it performed better at a soil water content of 100% for grain weight per hill.

The application of arbuscular mycorrhizal fungi can enhance the fertility of peat soils and reduce the requirement for NPK fertilization on the plat. The study aimed to evaluate the role of AMF in improving the growth and yield of bird’s eye chili and in supporting NPK fertilizer efficiency on peat soil. The experiment was conducted in Pontianak City, West Kalimantan, from July to November 2024, using a factorial completely randomized design. The first factor consisted of three levels of AMF application without AMF, AMF sourced from pineapple vegetation, and AMF sourced from weed vegetation. The second factor consisted of four levels of NPK fertilizer dosage 100% recommended NPK, 75% recommended NPK, 50% recommended NPK, and 25% recommended NPK. The results showed that the application of AMF significantly improved the growth and yield of bird’s eye chili on peat soil and enhanced the efficiency of NPK fertilization. The interaction between AMF and NPK dosages indicated that plants inoculated with AMF, particularly AMF from pineapple vegetation, exhibited greater plant height, higher plant dry weight, earlier flowering, and higher fruit weight per plant compared to plants without AMF across all fertilizer levels. The most optimal effect of AMF was observed at the 50% NPK dosage, which produced the best growth and yield performance, indicating that AMF application can reduce chemical fertilizer requirements without compromising crop productivity.
