Abstract

The utilization of alluvial soils for expanding agricultural land to increase maize production is constrained by low soil pH and limited availability of macronutrients. The application of oil palm shell charcoal as a soil ameliorant has the potential to improve soil properties and enhance the effectiveness of MKP fertilizer as a source of phosphorus and potassium. This study aimed to evaluate the interactive effects of oil palm shell charcoal and MKP fertilizer on the growth and yield of maize grown on alluvial soil. The experiment was conducted in Limbung Village, Kubu Raya Regency, from September 2025 to January 2026 using a split-plot design arranged in a randomized complete block design with three replications. Oil palm shell charcoal (without and with charcoal) was assigned as the main plot, while MKP fertilizer rates (0, 50, 100, 150, and 200 kg ha⁻¹) were applied as subplots. Observed variables included vegetative growth, physiological characteristics, and yield components. The results showed that the combination of oil palm shell charcoal and MKP fertilizer significantly improved maize growth and yield. The application of oil palm shell charcoal combined with MKP fertilizer at a rate of 150 kg ha⁻¹ produced the highest and most efficient yield, with a dry shelled grain weight of 216.28 g plant⁻¹.

Abstract

Soil salinity is one of the major limiting factors of soil fertility that directly affects rice growth and productivity. This study aimed to evaluate the role of mycorrhizal fungi in enhancing the growth and yield of rice plants under saline growing media conditions. The research was conducted at the Plant Seed Center, Peniraman Village, Sungai Pinyuh District, Mempawah Regency, from August to December 2025. The experiment was arranged in a split-plot design based on a randomized complete block design. The main plots consisted of without mycorrhizal fungi application and with mycorrhizal fungi application, while the subplots consisted of salinity levels of 0, 2, 3, 4, and 5 ppt. There were 10 treatment combinations, each replicated three times, with eight observation units, resulting in a total of 240 plants. The results showed that the application of mycorrhizal fungi increased rice productivity, as indicated by the grain weight per hill. Rice plants were able to tolerate soil salinity conditions up to 2 ppt, based on the variables of plant dry weight, panicle length, 1000-grain weight, and percentage of filled grains. No interaction was observed between mycorrhizal fungi application and salinity levels for all variables measured.

Abstract

Ubi jalar (Ipomoea batatas L.) merupakan jenis tanaman pangan umbi-umbian berasal dari Benua Amerika yang kaya nutrisi. Ubi jalar merupakan jenis tanaman merambat penghasil umbi yang memiliki potensi yang besar baik sebagai pangan alternatif dan bahan baku olahan dalam agroindustri. Tujuan dari penelitian melihat peranan pemberian paklobutrazol terhadap pertumbuhan dan hasil panen ubi jalar di tanah PMK dan Mencari konsentrasi paklobutrazol terbaik pada tanaman ubi jalar di tanah PMK. Penelitian ini dilaksanakan di lahan pertanian, Jalan Refomasi, Gg. Matematika, Blok H, Kec. Pontianak Kota, Kota Pontianak. Yang berlangsung pada bulan Agustus 2024 sampai dengan bulan Desember 2024. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) yang terdiri dari satu faktor yaitu Paklobutrazol (P) yang terdiri dari 8 taraf perlakuan. Setiap perlakuan diulang sebanyak 3 kali. sehingga diperoleh 24 satuan percobaan, dimana setiap satuan percobaan terdiri dari 3 unit sampel tanaman, sehingga jumlah keseluruhannya menjadi 72 tanaman. perlakuan yang di maksud adalah sebagai berikut : P0 : 0 ppm, P1 : 150 ppm, P2 : 300 ppm, P3 : 450 ppm, P4 : 600 ppm, P5 : 750 ppm, P6 : 900 ppm, dan P7 : 1050 ppm. Hasil penelelitian menunjukkan Pemberian paklobutrazol pada tanaman ubi jalar berpengaruh tidak nyata pada terhadap jumlah daun, jumlah cabang, panjang sulur 6 MST dan 8 MST, jumlah umbi, diameter umbi, berat umbi, dan panjang umbi. Pemberian paklobutrazol berpengaruh nyata terhadap panjang sulur pada 10 MST dan 12 MST tanaman ubi jalar aksesi ARF 08. pemberian paklobutrazol dengan konsentrasi 150 ppm merupakan hasil yang terbaik terhadap pertumbuhan dan hasil ubi Jalar aksesi ARF 08.

Abstract

Peanut (Arachis hypogaea L.) is a commodity with high economic value due to its high protein and fat content. Peanut productivity in West Kalimantan is still low compared to national productivity. Efforts to increase peanut production on peat soil include the application of liming and organic fertilizer. The objective of this study was to determine the best plant spacing and NPK fertilizer dose for the growth and yield of peanut on peat soil. The study was arranged using a Factorial Randomized Block Design. Plant spacing as the first factor consisted of 3 levels: J1 = 20 cm × 20 cm, J2 = 30 cm × 30 cm, J3 = 40 cm × 40 cm, and NPK fertilizer as the second factor consisted of 3 levels: N1 = 200 kg/ha, N2 = 250 kg/ha, N3 = 300 kg/ha, resulting in 9 treatment combinations replicated 3 times. Observed variables included root volume, root dry weight, number of pods, pod dry weight, seed dry weight, 100-seed weight, and seed dry weight per plot. The results showed that plant spacing and NPK fertilizer had no significant effect on all observed parameters, and there was no significant interaction between the two factors. Liming and organic fertilizer application increased soil pH from 4.34 to 5.25. The combination of 30 cm × 30 cm plant spacing with 200 kg/ha NPK fertilizer produced the highest seed dry weight per plot of 331.26 g, increasing by 64.2% compared to the lowest treatment, and was able to improve the growth and yield of peanut on peat soil. The combination of a 30 cm × 30 cm planting spacing with NPK fertilizer at 200 kg/ha produced the highest dry seed weight per plot, amounting to 331.26 g, which was 64.2% higher than the lowest treatment. This treatment was also able to improve the growth and yield of peanut plants grown on peat soil.The same treatment combination (30 cm × 30 cm spacing and 200 kg/ha NPK fertilizer) gave the best result, with dry seed productivity reaching 3.31 tons/ha, equivalent to 4.73 tons/ha of dry pods.
