This study aims to determine the interaction between multiple inoculations of Arbuscular Mycorrhizae and non-symbiotic N-fixing bacteria Azosprrillum at different urea fertilizer dosages on physiological processes and N, P uptake in peat soils. The study used a factorial design of 4x4 completely randomized layout with 3 replications. The first factor is the inoculation of Arbuscular Mycorrhizae and Azospirillum lipoferum (M) consisting of 4 levels, namely m0 (without inoculation), m1 (Arbuscular mycorrhiza inoculation), m2 (Azospirillum lipoferum inoculation) and m3 (inoculation with Arbuscular Mycorrhiza and Azospirillum. lipoferum). The second factor is the dose of urea with 4 levels, namely n0 (without urea fertilizer), n1 (urea urea recommended dose), n2 (½ recommended dose) and n3 (recommended dose). The dose of urea for maize is 150 kg ha-1. The data obtained were analyzed statistically using analysis of variance (F test), if the F test showed a significant difference between each treatment and interaction, it was followed by Duncan's multiple distance test at the 5% level. Observations were made on N and P uptake, Net Assimilation Rate (LAB) and relative growth rate (LPN). The results showed that the double inoculation of Arbuscular Mycorrhizae and Azospirillum lipoferum was effective at all doses of urea in increasing nutrient uptake of N and P.

The second factor was NPK fertilizer at 3 levels, namely n1 = 200 kg/ha equivalent to 5 g/polybag, n2 = 400 kg/ha equivalent to 10 g/polybag, n3 = 600 kg/ha equivalent to 15 g/polybag. Variables observed included: plant height (cm), dry weight (g), root volume (cm3), number of fruits per plant (fruit), fruit weight per plant (g), and fruit weight per fruit ((g). Yields The study showed that the interaction between rice husk ash and NPK fertilizer had no significant effect on all observational variables.The application of rice husk ash at a dose of 10 tons/ha was the best dose to increase the growth and yield of okra plants on peat soil.The application of NPK fertilizer at a dose of 400 kg/ha ha provides growth and yield of okra plants on peat soils. Keywords: Rice husk ash, NPK fertilizer, peatsoil INTISARITanaman Okra (Abelmoschus esculentus L. Moench) merupakan salah satu komoditas sayur yang bergizi tinggi dan ekonomi tinggi. Usaha yang dilakukan untuk meningkatkan produksi okra agar tinggi baik dari segi kuantitas dan kualitas dapat dilakukan melalui usaha perluasan areal tanam dan peningkatan hasil persatuan luas areal tanam adalah menanam tanaman okra pada tanah gambut. Penelitian ini bertujuan untuk mendapatkan dosis interaksi abu sekam padi dan pupuk NPK yang terbaik untuk pertumbuhan dan hasil tanaman okra di tanah gambut. Penelitian ini dilakukan di lahan Penelitian Fakultas Pertanian Universitas Tanjungpura. Penelitian dilakukan mulai pada tanggal 29 Mei - 27 Agustus 2022. Penelitian ini menggunakan metode eksperimen dengan pola Rancangan Acak Lengkap (RAL) faktorial dengan dua perlakuan dan 3 ulangan.

One of the efforts that can be made to improve the problem of low pH and low peat soil fertility is by providing ameliorant materials and organic fertilizer. Ameliorant is a material that can improve soil fertility and overcome soil acidity, one of which is red mud as a soil conditioner because it has a very alkaline pH. The objectives of this research are: 1. To assess the availability of N, P, K, Ca and Mg nutrients in peat media that is ameliorated with red mud and vegetable waste. 2. To assess the nutrient uptake of N, P, K in white radish grown in peat media with amelioration of red mud and vegetable waste bokashi.This research was carried out at the Experimental Field, Faculty of Agriculture, Tanjungpura University, Pontianak. This research used a Completely Randomized Factorial Design (CRD) with 2 factors. The first factor is red mud dosage (R) and the second factor is vegetable waste bokashi (B), Each factor consist of 3 level of dosage, Red mud dosage levels are: 16 tons/ha; 18 tons/ha; 20 tons/ha, the bokashi dosage level for vegetable waste is: 15 tons/Ha; 20 tons/ha and 25 tons/ha. Observation variables include the availability of nutrients N, P, K, Ca, Mg, uptake of nutrients N, P, K, dry weight and fresh weight of white radish. The research showed that the application of red mud and vegetable waste bokashi to peat soil was able to increase pH, base saturation, availability of the nutrients P, Ca, Mg, K and Na. However, the application of red mud and bokashi vegetable waste reduced the CEC and Organic C values of the soil. The uptake of the nutrients N, P and K was relatively the same between treatment combinations, the absorption of the N element was the greatest, followed by the elements K and P. The application of 18 tons/ha of red mud and 15 tons/ha of vegetable waste bokashi was an effective dose for the growth and yield of white radish on peat soil. Key words: peat, red mud, vegetable waste bokashi, radish INTISARI Satu di antara upaya yang dapat dilakukan untuk memperbaiki kendala pH rendah dan kesuburan tanah gambut yang rendah yaitu dengan pemberian bahan amelioran dan pupuk organik. Amelioran merupakan bahan yang dapat memperbaiki tanah dan mengatasi kemasaman tanah, salah satunya yaitu lumpur merah (Red mud) sebagai pembenah tanah karena memiliki pH yang sangat basa. Tujuan penelitian ini adalah: 1. Mengkaji ketersediaan hara N,P,K,Ca dan Mg pada media gambut yang diameliorasi dengan red mud dan bokasi limbah sayuran. 2. Mengkaji serapan hara N,P,K pada tanaman lobak yaang ditanam pada media gambut dengan ameliorasi red mud dan bokashi limbah sayuran. Penelitian ini dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Tanjungpura Pontianak. Penelitian ini menggunakan Rancangan Faktorial Pola Acak Lengkap (RAL) dengan 2 faktor. Faktor pertama yaitu dosis red mud (R) sebanyak 3 taraf dan faktor kedua yaitu Bokasi limbah Sayuran (B) sebanyak 3 taraf sehingga terdapat 9 kombinasi perlakuan. Taraf dosis red mud adalah: 16 ton/ha; 18 ton/ha ; 20 ton/ha, taraf dosis bokashi limbah sayuran adalah: 15 ton/Ha; 20 ton/ha dan 25 ton/ha. Variabel pengamatan meliputi ketersedian unsur hara N,P,K, Ca, Mg, serapan unsur hara N,P,K, berat kering dan berat segar tanaman lobak. Hasil penelitian menunjukkan bahwa pemberian red mud dan bokashi limbah sayuran pada tanah gambut mampu meningkatkan pH, Kejenuhan Basa, ketersediaan unsur hara P, Ca, Mg,K dan Na. Namun, pemberian red mud dan bokashi limbah sayuran menurunkan nilai KTK dan C Organik tanah. Serapan unsur hara N, P dan K relatif sama antar kombinasi perlakuan, penyerapan unsur N paling besar diikuti okeh unsur K dan P. Pemberian red mud 18 ton/ha dan bokashi limbah sayuran 15 ton/ha merupakan dosis efektif terhadap pertumbuhan dan hasil lobak pada tanah gambut.Kata kunci: Bokashi limbah sayuran, Gambut, Lobak, red mud
