Abstract

Data collection was gathered from PubMed, Google Scholar, Semantic Scholar, and Crossref in Harzing”s Publish or Perish software. The keyword used in this study was "Flooding Stress" with the publication year of the 1962-2021 articles. Results showed that PubMed retrieves more relevant manuscripts from journal sources than other databases. The search method by whole years was the most effective and efficient if the total manuscripts are less than 1000. Flooding stress-related manuscripts were published continuously from 1994 to 2021 with Annals of Botany as the most productive journal. A combination of “Flooding Stress” with related keywords, e.g., submergence stress, anaerobic stress, and oxidative stress, improves the relevancy of the manuscript results. VOSviewer keyword analysis found that there were 5 clusters discussing oxidative stress, tolerant mechanism, physiological mechanism, flood occurrence, and molecular mechanism. Based on the density visualizations, the anaerobic metabolism, mRNA expression level, SOD, fv/fm, leaf gas exchange, ABA biosynthesis, and halophyte lead to potential topics of flooding stress research to be studied in the future.

Abstract

Sustainable soil fertility management is crucial for global food security and addressing environmental challenges from modern agriculture. Soil health, alongside water availability, is essential for crop productivity, and soil degradation threatens food security by lowering yields and intensifying climate change. Nitrogen (N) cycling is central to soil fertility, supporting plant growth through nutrient replenishment and microbial activity. However, N is often lost through leaching, volatilization, and denitrification, reducing nitrogen use efficiency (NUE) and contributing to water pollution and greenhouse gas (GHG) emissions. Optimizing nitrogen retention in soils is vital for improving productivity and minimizing environmental harm. Biochar (BC) and humic substances (HSs) have emerged as effective strategies for improving N management. BC enhances soil fertility by increasing soil pH, cation exchange capacity, and water retention, while reducing nutrient leaching and promoting carbon sequestration. HSs, including humic acids (HA), fulvic acids (FA) and humin (HU), improve nutrient cycling by stimulating microbial activity and enhancing nutrient transport. Together, BC and HSs provide synergistic benefits for soil health, particularly in challenging environments like saline or nutrient-depleted soils. This review highlights the roles of BC and HSs in enhancing soil fertility, promoting N mineralization, and improving crop productivity. It emphasizes their potential for sustainable agricultural practices, climate change mitigation, and long-term soil health. Keywords: Biochar, Climate changes, Humic substances, Remediation, Soil fertility.

Abstract

The contribution of rice production in drylands (upland rice) to national rice production is still low, due to several limiting factors including limited water, low pH, and low soil fertility. This study aimed to obtain improved recommendations for amelioration and bioremediation in drylands with Al stress to enhance rice production. The upland rice variety of Inpago 12 was planted at Taman Bogo Experimental Farm, East Lampung in the first planting season of 2020. The experiment was arranged in a split-plot design with three replications. The main plot was the application of amelioration materials consisting of control (without amelioration), CaMg(CO3)2, CaCO3, and rock phosphate. The subplot was the application of bioremediation materials consisting of control (without bioremediation), biofertilizer, endophytic microbes, and citric acid. Results showed that amelioration and bioremediation on dry land with low to moderate Al stress and high Al stress did not significantly increase the growth of rice plants. However, bioremediation in the form of citric acid on land with low to moderate Al stress significantly increased grain production by 6.21% than without bioremediation. Keywords: Aluminium, dryland, limited water, rice production, low soil fertility, low pH

Abstract

The objective of this study was to investigate the impact of combining different doses and application methods of biofertilizers on the growth and yield of lowland rice (Oryza sativa L.) in West Java. The experiment was designed as a completely randomized factorial with two factors and three replications. The first factor included three different biofertilizer application methods, and the second factor consisted of five different biofertilizer doses. The use of high-fertility alluvial soil was favorable for rice growth when treated with biofertilizers. The interaction between the applied method and biofertilizer dosage had a significant impact on various growth parameters, such as plant height, tiller number, stem fresh weight (g), stem dry weight (g), leaf dry weight (g), panicle number per plant, filled grain number per plant, unfilled grain number per plant, and total grain weight (g). The application of 300 g per pot biofertilizer dose at planting time resulted in the highest filled grain weight per plant (58.6 g) and total grain weight per plant (65.1 g). However, while biofertilizers significantly enhanced rice plant growth, none of the four biofertilizer dose treatments were significant when compared to the control in any of the three application methods. Optimally dosed biofertilizers, when applied at proper planting time, can serve as an alternative approach to enhance rice growth and yield in alluvial soil. This eco-friendly technology has the potential to be integrated into field management practices.
