Published: June 17, 2024

This study explores agronomic management (AM) effects on soil parameters under diverse conditions. Investigating tillage practices (TP), nutrient (NM), crop rotation (CR), organic matter (OM), irrigation (IM), and mulching (MS), it aims to reveal impacts productivity, availability, microbial activity, overall health. Varied TP affect quality through compaction, porosity, erosion risk. Proper NM is vital for cycling, preventing imbalances acidification. CR disrupts pest cycles, reduces weed pressure, boosts recycling. OM enhances by influencing carbon, pH, fertility, water retention. Optimizing IM regulates content without inducing waterlogging. MS contributes content, retention, structure, temperature-moisture regulation, benefiting biota, aggregation, health agricultural productivity. The review emphasizes integrated nutrient, CR, management's positive impact fertility activity. Different variations production. Judicious implementation of these essential sustainable agriculture. synthesis identifies uncertainties proposes research directions optimizing productivity while ensuring environmental sustainability. Ongoing inquiry can guide a balanced approach between yields resilient stewardship future generations.

Abstract Soil depletion constitutes a major challenge for agriculture and food security in highlands of eastern Democratic Republic Congo (DRC). This study aimed to assess the effectiveness split-application nitrogen fertilizer on grain yield profitability maize Nitisols DRC. The urea (100 kg ha −1 ) was applied single, two, three split-applications varieties two cropping seasons. Results showed that growth parameters varied significantly with N splitting strategy, varieties, season ( p < 0.01). single application at 45th day after sowing presented highest (5.5 t compared both variety 'ZM 627' had seasons (5.4 5.8 2017 2018 seasons, respectively). benefit–cost ratio analysis more profitable, i.e. 1.63 USD (0.6 splits (0.22 fertilizer), though dependent used varieties. trend same agronomic efficiency (AE); yielded 11 grains. In addition, split applications resulted additional labor costs. from this do not, therefore, recommend strategy South-Kivu Nitisols.

Assessment of some biological properties of soils across selected farming communities of Southern and Northern Nigeria

Research Square (Research Square), Journal Year: 2025, Volume and Issue: unknown

Published: March 6, 2025

Background and Aims: This study examines the impact of soil biological parameters on agricultural productivity sustainability across Nigeria's diverse climates. Materials Methods: A multistage sampling method was adopted to collect 108 samples from four southern northern Nigeria locations, three communities, farmers' fields replicated times in a Complete Randomized Block Design (RCBD). Each sample analyzed for initial physicochemical some selected microbial properties. Results: In humid regions, activity high Location 1 (L1), with bacterial densities reaching 12.31 x 10⁷ CFU/ml associated fungal yeast at 1.55 10⁶ SFU/ml 5.08 counts, respectively. indicates bacterial-dominated ecosystem favourable rapid nutrient cycling, although it may risk structure over long term if unmanaged. Conversely, 3 (L3) drier areas showed less 9.83 but higher populations. suggests more environment that could enhance cycling structure, which is essential arid regions. The also investigated how environmental factors farming practices influence balances through hierarchical clustering analysis. Clusters like L3C1F2 L3C2F3 demonstrated balanced ecosystems substantial populations, supporting robust health. Conclusion: research highlights need precise, region-specific accommodate local profiles optimize crop yields sustain health, enhancing food security economic stability Nigeria.

Management strategies for improving maize yield and water productivity under water deficit and soil acidity

Experimental Agriculture, Journal Year: 2025, Volume and Issue: 61

Published: Jan. 1, 2025

Summary Maize holds a key role in ensuring food security Ethiopia, yet its productivity faces challenges due to water scarcity and soil acidity. Minimizing these problems is crucial enhance maize yield maintain security. This research explored the effects of deficit irrigation (DI) combined with lime, manure, inorganic fertilizer application on (WP) Koga, Ethiopia. Three levels DI, namely 80%, 60%, 50% crop evapotranspiration (ETc), alongside 100% ETc (full irrigation) as reference, were implemented for two consecutive seasons. Five integrated fertility management (ISFM) treatments evaluated over successive seasons: (i) combining 1.43 Mg ha –1 lime 3 manure full doses urea + (NPSB, containing 18.9% Nitrogen, 37.7% Phosphorus, 6.95% Sulphur, 0.1% Boron), referred (L1); (ii) 1.15 (L2); (iii) 0.86 (L3); (iv) applying (M); (v) using only (C). Grain biomass measured at harvest from 9 m 2 sample area each plot, three replicates. The liming manuring significantly influenced average grain biomass. Across all scenarios, higher production found L1, L2, L3, M compared treatment C. highest WP was under ISFM treatments. lowest recorded C across levels. Manuring reduced increased yield, biomass, use alone ETc. could mitigate negative impact DI yield.

Soil acidity is one of the major crop production constraints in highlands Ethiopia. Liming becoming a common practice to amend soil acidity, but its effects on properties, yield, and farm income are not well studied. In this study, an on-farm liming experiment was conducted for two consecutive years (2020-2021) acidic Nitisols (pH < 5.5) Southern The consisted six rates (control, 2.74, 4.11, 5.48, 6.85, 8.22 t·ha−1) laid out randomized complete block design with three replications. Soil, agronomic, economic data were collected 2020 2021 cropping seasons analyzed. application lime ranges 2.74–8.22 t·ha−1 increased pH by 0.46–1.25 units reduced exchangeable 2.02–3.17 units. Higher 6.85–8.22 sharply from 5.22 5.99 6.46, respectively, such rise proportionally reflected yield increment. available phosphorus contents 7.16 6.01 mg·kg−1 measured at 4.11 5.48 t·ha−1, respectively. Combined over years, 5.45 yielded highest barley total biomass 19,199 kg·ha−1 grain 4,328 kg·ha−1, which 46% 30% higher than those control, It also marginal rate return 477% gross margin 192,857.3 ETB1·ha−1, 53% control.
