Abstract

Tanah Inceptisol memiliki kendala kesuburan berupa rendahnya kandungan bahan organik, kapasitas tukar kation (KTK), dan nitrogen. Penelitian Ini bertujuan untuk menentukan dosis optimal bahan pembenah tanah (kompos eceng gondok, biochar jerami, dan asam humat) yang diperkaya asam amino terhadap sifat kimia tanah dan hasil panen padi (Oryza sativa L.) di rumah kaca pada tanah Inceptisol Jatinangor. Metode penelitian menggunakan Rancangan Acak Kelompok (RAK) dengan tujuh perlakuan, mulai dari kontrol, dosis tunggal NPK, hingga kombinasi bahan pembenah tanah dengan berbagai dosis NPK (¼, ½, ¾, dan 1 dosis yang direkomendasikan). Parameter yang diukur meliputi Kapasitas Tukar Kation (KTK) tanah, nitrogen total, penyerapan nitrogen, dan berat gabah kering giling (GKG). Hasil penelitian menunjukkan bahwa aplikasi bahan pembenah tanah yang diperkaya asam amino secara signifikan meningkatkan komponen hasil panen. Kombinasi bahan pembenah tanah dengan ½ hingga ¾ dosis NPK yang direkomendasikan mampu menghasilkan GKG yang setara dengan dosis NPK penuh. Hal ini menunjukkan bahwa bahan pembenah tanah dapat meningkatkan efisiensi penyerapan nitrogen dan memperbaiki retensi nutrisi pada tanah Inceptisol. Oleh karena itu, penggunaan bahan pembenah tanah ini secara efektif mengurangi kebutuhan pupuk anorganik sambil mempertahankan produktivitas padi.

Abstract

Global food security is increasingly threatened by abiotic stresses, particularly waterlogging, which poses significant challenges to cereal crop production. Waterlogging is one of the primary abiotic stresses that significantly influence the interrelationships among plant physiology, growth, and yield. This review aims to examine the relationships among these three aspects in cereal crops, with an emphasis on the response mechanisms to waterlogging stress. Findings from the reviewed literature indicate that waterlogged conditions induce hypoxia in the root zone, leading to reduced photosynthetic rates, impaired nutrient uptake, and increased production of reactive oxygen species (ROS), which trigger cellular damage. These effects result in reduced plant growth and yield. Nevertheless, plants exhibit various adaptive mechanisms, such as aerenchyma formation, adventitious root development, and proline accumulation, which enhance tolerance to stress. Variations in tolerance levels among cereal species also influence the extent of yield reduction. Overall, improving plant tolerance to waterlogging stress requires an integrated approach through physiological understanding, genetic improvement, and the application of appropriate agronomic management.

Abstract

Mung bean (Vigna radiata L.) is an important crop contributing to global food security. However, its productivity is severely affected by drought stress, particularly during the growth and grain filling stages. Drought stress reduces yield components such as pod number, seeds per pod, and grain weight due to disruptions in physiological and metabolic processes. It also negatively impacts crop quality by limiting nutrient accumulation and grain development. Potassium plays an important role in increasing plant tolerance to drought stress through various mechanisms. At the physiological level, potassium increases the efficiency of photosynthesis, regulates stomatal function, and maintains cellular osmotic balance, allowing plants to maintain turgor and metabolic activity under conditions of water deficit. At the biochemical level, potassium activates antioxidant enzymes that mitigate oxidative damage caused by reactive oxygen species. Furthermore, potassium supports the translocation of assimilates from source to recipient organs, thus promoting pod formation and grain filling. Adequate potassium supply also improves crop quality, including better nutrient content and grain uniformity. The interaction between potassium and water availability exhibits a synergistic effect, with optimal potassium levels increasing water use efficiency and mitigating the negative impacts of drought stress. Therefore, proper potassium management combined with efficient irrigation strategies is crucial for maintaining mung bean productivity and quality under drought conditions, thus supporting a more adaptive and sustainable agricultural system.

Abstract

Climate change and increasing water scarcity have intensified drought stress, reducing mung bean (Vigna radiata L.) yield and seed quality. Silica fertilization has gained attention as a strategy to enhance plant tolerance to water limited conditions and improve crop productivity. This study systematically reviewed the effects of silica fertilization and irrigation frequency on mung bean yield and quality using the PRISMA 2020 framework. Literature was collected from major scientific databases, and 68 eligible studies published between 2010 and 2026 were selected for qualitative synthesis. The reviewed studies consistently showed that reduced irrigation frequency decreased growth, physiological performance, yield, and grain quality. In contrast, silica fertilization improved water status, photosynthetic efficiency, antioxidant activity, nutrient uptake, and drought tolerance. Evidence from mung bean and related legume crops demonstrated that silica application enhanced pod formation, seed weight, biomass accumulation, and yield stability under water deficit conditions. The benefits of silica became more pronounced as water availability declined, indicating a complementary relationship between silica fertilization and irrigation management. Overall, integrating silica fertilization with optimized irrigation scheduling offers a promising approach to improve yield, maintain seed quality, enhance water use efficiency, and support sustainable mung bean production under drought prone environments.

Abstract

Mung bean (Vigna radiata L.) is an important legume crop that plays a strategic role as a source of plant-based protein, a functional food ingredient, and an adaptive crop widely cultivated in various tropical and subtropical regions. Mung bean are a legume crop with high agronomic potential, mung bean productivity still faces several challenges, particularly due to climate change and rainfall patterns. These environmental changes can reduce water availability in agricultural lands and increase the risk of drought stress. Low water availability is one of the primary limiting factors in mung bean cultivation because it impedes overall plant performance, such as growth, phenological development, and physiological functions. Water deficit can disrupt plant biological processes through reduced tissue water status, impaired nutrient uptake and distribution, decreased metabolic activity, and increased oxidative stress, which eventually leads to reduced productivity. Under drought stress conditions, potassium (K) plays a crucial role as an essential nutrient that helps improve plant tolerance to water limitations. Potassium contributes to maintaining osmotic balance, improve water use efficiency, support physiological stability, and strengthening plant adaptation mechanisms against drought stress. Therefore, proper potassium management can be a potential strategy to improve mungbean resilience and maintain plant performance under low water availability conditions.

Abstract

The demand for high-quality pineapple (Ananas comosus (L.) Merr.) planting materials continues to increase, while conventional propagation methods are limited in multiplication rate, uniformity, and production efficiency. In vitro culture offers an alternative approach for rapid and large-scale seedling production. However, information on the effects of thiamine and cytokinin combinations on both shoot multiplication and phenolic-flavonoid accumulation in pineapple in vitro remains limited. This study evaluated ten defined combinations of thiamine and cytokinin for shoot multiplication and total phenolic-flavonoid contents of pineapple explants. The experiment employed a completely randomized design with 10 treatment combinations of thiamine (0.1 and 0.4 mg/L), cytokinin TDZ (0.01 and 0.1 mg/L) and BAP (1 and 2 mg/L) with three replications. The combination of 0.1 mg/L thiamine and 1 mg/L BAP produced the highest number of shoots (3.33 shoots) and leaves (17.56 leaves). In contrast, 0.4 mg/L thiamine combined with 0.1 mg/L resulted in the earliest shoot emergence (54.67 day after subculture) and the highest total phenolic content (13.62 mg GAE/g DW) and total flavonoid content (15.41 mg QE/g DW). No visible browning symptoms were observed in this treatment. These findings demonstrate that the optimal culture conditions differed according to the intended objective, 0.1 mg/L thiamine with 1 mg/L BAP favored shoot proliferation and leaf development, whereas 0.4 mg/L thiamine with 0.1 mg/L TDZ favored phenolic and flavonoid accumulation.
