Abstract

Tanaman padi (Oryza sativa L.) merupakan komoditas strategis dalam menjaga ketahanan pangan nasional. Berbagai upaya dilakukan agar hasil panen tanaman padi terus meningkat. Aplikasi silika (Si) pada tanaman padi masih jarang dilakukan oleh petani sebagai upaya untuk meningkatkan produktivitas tanaman padi. Penelitian ini bertujuan untuk menentukan konsentrasi terbaik aplikasi Si pada setiap status Si tanah sawah terhadap produktivitas tanaman padi. Penelitian ini menggunakan metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan ulangan tidak sama. Terdiri dari sembilan perlakuan yang merupakan kombinasi antara status Si tersedia (rendah, sedang dan tinggi) dan aplikasi Si (tanpa pemupukan, ekstrak silika sekam padi 20 dan 40 mL L-1. Variabel penelitian yang diamati yaitu jumlah malai umur 84 dan 98 hari setelah tanam, berat kering biomassa jerami, berat gabah per 1000 butir, berat gabah per rumpun dan berat gabah konversi per hektar. Hasil penelitian menunjukkan bahwa konsentrasi optimum aplikasi Si berbeda-beda bergantung pada status Si dalam tanah. Level optimum aplikasi Si diperoleh konsentrasi 11 dan 28 mL L-1 untuk Si tersedia sedang dan tinggi. ABSTRACT Rice is a strategic commodity for maintaining national food security. Various efforts are being made to increase rice yields. Application of silica (Si) on rice plants is still rarely carried out by farmers as an effort to increase rice productivity. This study aims to determine the optimal concentration of Si application at each Si status of paddy soil for rice plant productivity. The method used in this study is an experimental method using a completely randomized design with unequal replications. Consisting of nine treatments, a combination of available Si status (low, medium and high) and Si application (no fertilization, rice husk silica extract 20 and 40 mL L-1). The research parameters observed were the number of panicles at 84 and 98 days after planting, dry weight of straw biomass, grain weight per 1000 grains, grain weight per clump and converted grain weight per hectare. The results indicated that the optimal Si application concentration varied according to the soil Si status. The optimum Si application was at concentration of 11 mL L-1 of 28 mL L-1 in paddy soil with a medium and high available Si status, respectively.

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

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.
