Abstract

Sweet corn (Zea mays L. saccharata) productivity on peat soils is often constrained by high acidity, low fertility, and limited nutrient availability. Organic-based soil amendments such as rice husk ash and cattle manure may improve soil chemical properties and support crop growth on peatlands. This study aimed to evaluate the effects of rice husk ash and cattle manure on the growth and yield of sweet corn cultivated on peat soil. The field experiment was conducted from December 2022 to February 2023 at Bandar Agung Village, Lalan District, Musi Banyuasin Regency, while laboratory analyses and data processing were completed from June 2022 to May 2023. The study used a factorial randomized block design with two factors and three replications. Rice husk ash was applied at rates of 0, 30, and 60 t ha⁻¹, while cattle manure was applied at 0, 42, and 84 t ha⁻¹. The results showed that treatment A2S1 (60 t ha⁻¹ rice husk ash and 42 t ha⁻¹ cattle manure) tended to produce higher values for several yield parameters, particularly cob length, cob weight, and cob diameter. The treatments significantly affected cob diameter, number of leaves, cob length, and cob weight with husk and without husk, whereas plant height, plant wet weight, and plant dry weight were not significantly affected. The application of rice husk ash, cattle manure, and dolomite also increased soil pH under acidic peat soil conditions. These findings indicate that appropriate combinations of organic amendments may improve sweet corn productivity and support sustainable peatland agriculture.

Abstract

Pacarejo, a village in Kapanewon Semanu, is located a karst area. Karst conditions cause the ability of land for agriculture to be very limited. However, this is an opportunity to develop dry land into productive agricultural land by planting potential crops that are suitable for land conditions and having a good economic value. The purpose of the study was to determine the level of land suitability in Pacarejo Village for upland red rice. This study used a survey method. Land system maps were produced from overlays of land use maps, land type maps, and slope maps so that 37 land systems were obtained. The determination of sampling points used the purposive sampling method based on the selected land system, namely 11 sample points by excluding settlements and land with steep slopes. The data analysis method used matching between land characteristics and suitability criteria for crops according to the Technical Guidelines for Evaluating Suitability for Agricultural Commodities. The results showed that the suitability class for upland red rice was S3 (Marginal Suitable) covering an area of 1.636,63 ha (57,87%) with limiting factors of oxygen availability (oa), root conditions (rc), and nutrient retention (nr). Land suitability in several land systems can potentially be improved to S2 class by improving the limiting factors of rapid soil drainage and low soil base saturation.Keywords: upland red rice, karst, soil mapping unit, land suitability, Pacarejo

Abstract

Methane emissions from the agricultural sector represent a critical challenge for global climate change mitigation. This study aims to map the patterns, trends, and development of research on methane emission reduction in the agricultural sector through the implementation of Alternate Wetting and Drying (AWD) using a bibliometric approach. Scientific publication data were collected from Scopus and analyzed following the PRISMA method, resulting in 325 relevant articles for analysis using VOSviewer. The results reveal a significant increase in publications, particularly after 2021, and identify five main thematic clusters ranging from biophysical responses to environmental quality. Temporal analysis indicates a shift in research focus from biophysical approaches toward the integration of climate mitigation, resource-use efficiency, and sustainable agricultural systems. This study concludes that AWD is an effective mitigation strategy with strong potential to reduce methane emissions without compromising rice productivity. Ultimately, these findings underscore the necessity of integrating AWD into future sustainable agricultural policies and climate mitigation actions to advance low-carbon food production globally. Keywords: Alternate wetting and drying, bibliometric analysis, low-carbon agriculture, methane emission reduction, sustainable agriculture

Abstract

The Notopuro Formation tuff in western part of Sragen Regency, Central Java, a region of economic importance and agricultural productivity, has been subject to limited geochemical, weathering, and mineralogical research, along with its residual soil. Understanding these characteristics is vital for safe construction and land use, given their influence on soil properties like cation exchange capacity, plasticity, water retention, and nutrient dynamics, which also indicate agricultural potential and geotechnical challenges. This study aims to fill this knowledge gap by comprehensively analyzing the geochemistry, weathering, and mineralogy of the Notopuro Tuff and its residual soils. Advanced techniques such as SEM, thin section petrography, and XRD will be employed. The tuff originates from a basaltic andesite magma with low-K, calcic, and magnesian affinity, exhibiting metaluminous alumina saturation. Its composition is primarily lithic fragments (50%) and volcanic glass (39%). Observed weathering involves Al2O3 and Fe2O3 enrichment, with the latter being more pronounced. SiO2 stability suggests kaolinitization, not lateritization or bauxitization. Weathered tuff crystal minerals include microcline and quartz, with notable cristobalite and magnetite, and generally low crystallinity.
