The common bean (Phaseolus vulgaris L.) is an important food crop in tropical agriculture. However, fertilization and soil management methods for common beans require further investigation to reduce production costs and increase sustainability. Furthermore, cultivation methods can directly affect GHG emissions. Thus, this study evaluates the CO2 emissions from fuel consumption as a function of soil management and fertilization methods on the common bean crop. The randomized block design was used in a 2 × 3 factorial scheme with six repetitions composed of two fertilization systems (spread and furrow) and three soil management systems: convention-al tillage—CT, minimum tillage—MT, and no-tillage—NT. The productive performance of common beans varies according to fertilization methods and soil management. Field capacity in the (CT) was impaired due to the various mechanized soil preparation operations with 0.30 and 0.32 ha h−1, without a significant effect from the fertilization method. CT system resulted in higher CO2 emissions of 175.74 kg ha−1 and 165.50 kg ha−1; thus, in soil conservation management, these same values were up to 58% lower, with the lowest rates for NT. Crop yield in the MT system presented the best result compared to the CT and NT, with an appropriate cost–benefit ratio for bean production in tropical crops.
Increased food production has become a global urgency due to population growth and limited productive land. Efficient use of resources, particularly water, and optimization of marginal land such as peat soil are important strategies in sustainable agricultural production. This study introduces a novel combination of water depth management and biochar application to improve rice growth and yield on peat soils, an approach that has been rarely explored. The study was conducted using a Randomized Block Design with a 4 × 4 factorial pattern consisting of two factors. The first factor was water depth with four levels: 0, 3, 6, and 9 cm. The second factor was biochar dose with four levels: 0, 4, 6, and 8 tons ha−1. The results showed that water level did not significantly affect rice plant growth and yield. However, biochar dose treatment significantly affected plant height growth and plant productivity. The control treatment (without biochar) produced a yield of 1.47 ton ha−1, which falls within the typical range of rice yields on peat soils (1.1-1.9 tons ha−1). Application of 6 tons ha−1 of biochar increased yield by 1.12 tons ha−1 compared to the control, representing an improvement of approximately 76%. These findings indicate that the combination of water depth management and biochar application effectively improves rice productivity on peat soils. This study contributes new insights to peatland rice management by recommending a water depth of 0 cm combined with 6 tons ha−1 of biochar as an effective and sustainable strategy to enhance rice yield.

Sustainable agriculture, particularly efficient nitrogen management, is essential for maintaining soil fertility, improving crop quality, and reducing the environmental footprint of agricultural production. This study evaluated the effects of reduced soil-applied nitrogen and foliar application of the nitrogen–sulfur fertilizer Nitron-S on the quality of silage maize (Zea mays L.). A field experiment was conducted using a single-factor design with four fertilization treatments differing in nitrogen supply and foliar fertilization intensity. The silage maize cultivar Farmmortiz was grown under uniform manure application (30 t ha−1) applied in autumn. The control treatment received the full soil-applied nitrogen rate, whereas experimental treatments received 50% of the conventional nitrogen dose supplemented with foliar Nitron-S at doses of 20, 40, and 60 dm3 ha-1, applied twice during the growing season. After harvest, plant yield and selected quality parameters were determined, including dry matter, crude protein, sugars, starch, ash, neutral detergent fiber (NDF), acid detergent lignin (ADL), ammonia fraction, and organic matter digestibility (VOS). Fertilization treatments significantly affected most quality traits. The highest Nitron-S rate increased starch concentration (up to approximately 30% under N4) but also elevated ADL content (by about 25%) and slightly reduced VOS (only by about 1–3%. Partial replacement of soil-applied nitrogen with foliar nitrogen–sulfur fertilization improved the nutritional quality of maize silage and reduced nitrogen input. This approach may contribute to more sustainable maize production.

The sustainable management of soil fertility is essential for improving common bean (Phaseolus vulgaris L.) productivity under the semi-arid conditions of Afghanistan. This study evaluated the comparative effects of two organic fertilizers, inorganic fertilizer (NPK), and their integrated application on the growth and yield performance of common bean during the 2025 growing season at the Research Farm of the Faculty of Agriculture, Kabul University. The experiment was arranged in a Randomized Complete Block Design (RCBD) with six fertilizer treatments and three replications. Growth traits, yield components, grain yield, biological yield, and harvest index were analyzed using analysis of variance (ANOVA), and treatment means were separated by Tukey’s HSD test at the 5% probability level. Fertilizer treatments significantly influenced most growth and yield parameters. The integrated application of 50% OF-1 + 50% NPK (T5) consistently produced superior plant growth, increased yield components, and achieved the highest grain yield, biological yield, and harvest index compared with the sole application of organic or inorganic fertilizers and the unfertilized control. The improved performance of the integrated treatment was attributed to enhanced nutrient availability and more efficient nutrient utilization throughout the crop growth period. These findings demonstrate that integrated nutrient management is a sustainable and effective strategy for increasing common bean productivity under semi-arid agroecological conditions. Future studies should evaluate long-term effects of integrated nutrient management under diverse agroecological conditions.

Environmental pollution caused by excessive nitrogen fertilization has become increasingly serious, making optimized fertilization and straw management critical for improving agricultural sustainability. This study involved a two‐year field trial with three fertilization strategies: conventional fertilization (CF), 23.50% nitrogen reduction (RCF), and 23.50% nitrogen reduction with 20.00% organic fertilizer substitution (OF). Additionally, three straw management practices were tested: straw removal with shallow tillage (SRS), straw incorporation with shallow tillage (SIS), and straw incorporation with deep plowing (SID). The effects of these treatments on rice yield, pollutant emissions, and soil quality were systematically assessed. The results indicate that both RCF and OF maintained stable rice yields. RCF significantly reduced AUC‐NH

‐N (by 10.72%–12.77%), whereas OF significantly decreased AUC‐TP (by 71.01%–74.25%) and methane emissions (by 22.06%–28.81%), while markedly increasing SOC and TN. SID showed the best performance across all straw management practices. Overall, the OF‐SID strategy maintained rice yield while reducing pollutant emissions and enhancing soil fertility, thereby contributing to agricultural sustainability. This study provides new insights into the synergistic effects of fertilization and straw management on rice productivity, environmental pollutant emissions, and soil fertility, offering a scientific basis for developing sustainable nutrient management strategies in rice‐based cropping systems.

Abstract Common bean (Phaseolus vulgaris L.) is cultivated worldwide due to its adaptability to diverse environmental conditions and high nutritional value. However, in most Brazilian soils, phosphorus (P) availability is limited because of strong adsorption to iron and aluminum oxides, making large fertilizer inputs necessary and increasing production costs. In this context, organic fertilization emerges as a potential alternative to improve P availability while enhancing soil quality. This study aimed to evaluate the performance of common bean under different sources and rates of phosphorus fertilization in acid soil. Six treatments were tested: control (no P fertilization), chemical fertilization with single superphosphate (SSP), and organic fertilization (Agregare Environmental Solutions) corresponding to 50%, 100%, 150%, and 200% of the recommended P rate. The evaluated traits included number of pods per plant, grains per pod, grains per plant, final plant population, shoot dry mass, 100-grain weight, and grain yield. Chemical fertilization with SSP provided the highest productivity and overall agronomic performance. Organic fertilization, regardless of rate, did not result in significant differences among treatments. These findings highlight the higher agronomic efficiency of soluble phosphate fertilizers in short-cycle crops grown in acid soils, while emphasizing the need for integrated management strategies combining organic inputs and soil correction practices for sustainable production systems.

The experiment was conducted using a split-plot design to investigate the effect of different types of green manures viz. Fallow, Eichhornia crassipes, Sesbania aculeata, and Sorghum bicolor ssp. drummondii Cyperales as the main plot treatments along with three nitrogen management treatment levels (50% urea and 50% FYM) at rates of 90 kg ha− 1 (N60), 120 kg ha− 1 (N80), and 150 kg ha− 1 (N100) as sub-plot treatments on soil properties and crop production. Results indicated that Sesbania aculeata and N100 significantly enhanced biological yields, with increase in rice yields by 36.2% and 26.3%, and baby corn yields by 27.6% and 18.2% respectively, compared to fallow and N60 treatments. Moreover, Sesbania aculeata and N100 led to improvements in organic matter, soil microbial biomass carbon, fungal population, bacterial population, actinomycetes population, dehydrogenase activity, and urease activity compared to fallow and N60 treatments. These outcomes highlight the synergistic benefits of integrating Sesbania aculeata with N100 nitrogen levels, emphasizing the need for long-term studies to further assess their impacts on soil health and sustained crop productivity.
