Abstract

Water hyacinth (Eichhornia crassipes) compost provides a sustainable opportunity to improve soil fertility while managing an invasive aquatic weed. This study evaluated the optimal combination of water hyacinth compost and NPKS fertilizers for enhancing soil chemical properties, nutrient uptake, and shallot (Allium ascalonicum L.) yield on Inceptisols. The experiment was conducted from July to October 2023 using a Randomized Complete Block Design with seven fertilization treatments, including a control treatment without compost or NPKS, a compost-only treatment, a full NPKS treatment, and four combined treatments consisting of compost at ¼, ½, ¾, and 1 dosage levels each paired with ¾ of the recommended N, P, K, and S fertilizers. Results showed substantial improvements in soil chemistry, particularly in treatments combining compost with reduced mineral fertilizer rates. Soil pH increased toward neutral conditions, total nitrogen rose from 0.10% in the control to 0.32%, and available phosphorus and potassium increased more than fourfold compared with unfertilized soil. The treatment of ¾ compost dose (18.75 t ha⁻¹) + ¾ recommended NPKS consistently produced the highest soil nutrient availability, reflecting enhanced mineralization and nutrient retention. Nutrient uptake by shallot plants also improved markedly, with nitrogen, phosphorus, and potassium absorption increasing two- to threefold relative to the control. These improvements corresponded with clear gains in crop performance: the number of bulbs increased from 5 in the control to 9, and fresh bulb weight rose from 92.89 g to 132.26 g. Integrated treatments outperformed both compost-alone and full mineral fertilization. These findings indicate that combining water hyacinth compost with reduced NPKS fertilization can maintain high shallot productivity while decreasing reliance on chemical fertilizers, enhancing soil fertility, and providing an environmentally beneficial use for invasive aquatic biomass—supporting sustainable and circular nutrient management in low-fertility tropical soils

Abstract

Gold mine tailings are characterized by low organic matter, poor nutrient availability, extreme pH conditions, and unfavorable texture, all of which restrict plant growth. This study evaluated the effects of cow manure (CM) on soil chemical properties, carbon-to-nitrogen (C/N) ratio, and the growth and biomass of water kale (Ipomoea reptans Poir.) cultivated in tailings-based media. A greenhouse experiment was arranged in a randomized block design consisting of five treatments: 0% (control), 15%, 30%, 45%, and 60% CM (v/v), each replicated six times. Observations included soil pH, organic carbon, total nitrogen, C/N ratio, plant growth parameters, biomass, and microbial populations at 35 days after planting. The application of CM significantly increased organic C, total N, and the C/N ratio, with the highest values observed at 60% CM. However, higher CM doses reduced substrate pH to slightly acidic levels. The 15% CM treatment produced the greatest improvements in plant growth and biomass, increasing plant height by 21%, stem thickness by 29%, leaf number by 8%, and fresh and dry biomass by 73% and 120%, respectively, compared with the control. Increasing CM above 15% enhanced the C/N ratio but did not further improve plant performance, likely due to reduced nitrogen availability associated with higher organic matter and slower mineralization. CM applications did not significantly affect bacterial or fungal populations in the rhizosphere. Overall, the findings indicate that low-dose CM (15%) is optimal for improving the C/N ratio, supporting nutrient availability, and enhancing water kale growth in tailings. This study demonstrates the potential of organic amendments for rehabilitating gold mine tailings and highlights their role in restoring soil functionality and supporting sustainable revegetation efforts.

Abstract

The application of organic amendments is an important strategy to improve seedling quality in coffee nurseries. This study aimed to evaluate the effects of coffee husk compost and biochar, appliedsingly and in combination, on the growth of Arabica coffee seedlings. The experiment was conductedin a nursery using polybags filled with 5 kg of growing media and arranged in a randomized completeblock design with seven treatments and four replications. The treatments consisted of a control, coffeehusk compost alone, biochar alone, and combinations of compost and biochar at different rates.Growth parameters observed included plant height, stem diameter, and number of leaves. The resultsindicated that all amended treatments significantly improved seedling growth compared to thecontrol. The best growth performance was consistently obtained from the combined application ofcoffee husk compost at 300 g polybag⁻¹ and biochar at 200 g polybag⁻¹, which produced the highestplant height, stem diameter, and leaf number. This treatment demonstrated a synergistic effectbetween coffee husk compost as a nutrient source and biochar as a soil conditioner that improved thegrowing media environment. These findings suggest that the combined use of coffee husk compost andbiochar at appropriate rates is an effective approach to enhance vegetative growth and overall qualityof Arabica coffee seedlings in nursery systems.

Abstract

Rice productivity in Inceptisols is often constrained by high phosphate fixation and low nutrient efficiency, despite high total nutrient reserves. This study aimed to evaluate the effectiveness of silicaenriched biochar in improving soil chemical properties and maintaining rice yield under reduced N, P, K fertilization. A field experiment was arranged in a Randomized Block Design with two factors: silicaenriched biochar (0, 1.25, and 2.5 t ha-1) and N, P, K fertilizer dosages (0, 50%, and 100% of the  recommended dose). Observed parameters included Cation Exchange Capacity (CEC), available phosphorus, total soil silica, and yield components. The results showed a significant interaction between treatments on soil chemical properties, particularly CEC and pH. Application of 2.5 t ha-1 silica-enriched biochar independently increased available phosphorus by 24.3% and total soil silica by 5.9% compared to the control, likely due to phosphate desorption mechanisms. Agronomically, while N, P, K fertilizer was the dominant factor for yield, the combination of 2.5 t ha-1  silica-enriched biochar  with 50% N, P, K dosage produced Milled Dry Grain (MDG) yields that were statistically comparable to the 100% N, P, K treatment. This indicated that silica-enriched biochar can substitute up to 50% of inorganic fertilizer requirements without compromised yield

Abstract

Inceptisols is a soil order that usually low in organic matter and nutrient content. This condition resulted to dominantly sub optimal soil that is required to be amended prior cultivation process.Inceptisols properties can be enhanced through the addition of organic matter such as water hyacinthcompost, straw biochar, humic acid, and guano. Besides organic matter, the integration of NPKfertilizer can improve the chemical and physical characteristics of the soil, nutrient availability, andoptimize rice productivity in Inceptisols. This experiment aimed to identify the optimal dosage of soilamendments in combination with N, P, and K fertilizers to maximize phosphorus availability in the soiland plants, as well as rice yields in Inceptisols. This experiment took place from September 2025 toJanuary 2026 at the Soil Chemistry and Plant Nutrition Laboratory Experimental Garden, Faculty ofAgriculture, Universitas Padjadjaran, Jatinangor, Sumedang. The experiment used a RandomizedComplete Block Design with six treatments and four replications, that is: control; recommended N, P,K; soil amendment; ½ soil amendment + ¾ dose of N, P, K; 1 soil amendments + ½ dose of N, P, K; 1 ½soil amendment + ¼ dose of N, P, K. One dose of soil amendment used was 8000 kg ha-1, while one doseof N, P, K fertilizer was 350 kg ha-1 Urea, 50 kg ha-1 SP-36, and 50 kg ha-1 KCl. The results of theexperiment showed that the dose of 1 soil amendment + ½ dose of N, P, K yielded a percentage of grainper panicle of up to 94.75% and provided the highest available P and P uptake by plants.

Abstract

Modern agriculture largely depends on NPK fertilization however, the neglect of secondary nutrients, particularly magnesium (Mg) and sulfur (S), has increasingly led to nutrient imbalances andreduced fertilizer efficiency. Magnesium plays a crucial role in photosynthesis, energy transfer, andenzyme activation, and its deficiency often referred to as the “forgotten element” has become moreprevalent in intensive cropping systems and leached mineral soils. This study aimed to evaluate therole of magnesium–sulfur (Mg–S) fertilizer derived from kieserite in enhancing the growth and yieldof sweet corn (Zea mays saccharata L.) cultivated on Inceptisol soil. This study used a RandomizedBlock Design (RBD) with seven different combination treatments between kieserite (½; ¾; 1; 1 ½ andNPK (¾ and 1) recommended dosages, one treatment recommendation dose of local farmer and onetreatment without fertilizer for comparison. Each treatment was replicated three times, resulting in atotal of twenty-seven experimental plots. Soil chemistry parameters as a main object of thisexperiment. The results of this study showed that the application of kieserite inorganic fertilizersignificantly improved N, P, K, and Mg concentrations in plant tissue, increased total soil Mg content,and enhanced yield components of sweet corn compared to the control and standard NPK treatments.The combined application of one dose of kieserite (300 kg ha⁻¹) and the recommended NPK rate (350–100–50 kg ha⁻¹) produced the highest yield, reaching 14.24 t ha⁻¹, indicating that balanced Mg–Ssupplementation is essential for optimizing nutrient efficiency and maximizing sweet cornproductivity on Inceptisol soils.

Abstract

Secara umum, Inceptisols merupakan jenis tanah dengan kondisi kesuburan yang masih terbatas terutama terkait ketersediaan unsur hara mikro, sehingga dapat membatasi pertumbuhan dan hasil tanaman tomat. Praktik pemupukan yang hanya mengandalkan unsur hara makro sering kali belum mampu mencapai produktivitas optimal apabila tidak didukung oleh pupuk majemuk mikro, khususnya tembaga (Cu). Penelitian ini dirancang untuk mengevaluasi pengaruh pupuk N, P, K yang dikombinasikan dengan pupuk majemuk mikro melalui aplikasi foliar terhadap penyerapan Cu dan hasil tanaman tomat (Solanum lycopersicum L.) pada Inceptisols di Jatinangor, serta menentukan kombinasi pupuk yang paling efektif. Percobaan dilaksanakan pada bulan September hingga Desember 2025 di Lahan Percobaan Cileles, Fakultas Pertanian, Universitas Padjadjaran. Penelitian disusun menggunakan rancangan acak kelompok dengan enam perlakuan dan empat ulangan, yaitu tanpa pupuk (kontrol); 1 dosis rekomendasi N, P, K; 1 N, P, K + ½ majemuk mikro; 1 N, P, K + 1 majemuk mikro; 1 N, P, K + 1½ majemuk mikro; serta ¾ N, P, K + 1 majemuk mikro. Hasil penelitian mengindikasikan bahwa pemberian kombinasi pupuk N, P, K dan pupuk majemuk mikro memberikan pengaruh nyata terhadap peningkatan serapan Cu serta hasil tanaman tomat. Perlakuan berupa ¾ dosis N, P, K yang dikombinasikan dengan 1 dosis pupuk majemuk mikro menghasilkan penyerapan Cu tertinggi sebesar 25,71 mg tanaman⁻¹ serta komponen hasil terbaik, meliputi bobot buah per petak 10,42 g, bobot buah rata-rata 58,75 g, dan diameter buah 45,6 mm.
