Effect of Soil Aeration and Root Morphology on Yield under Aerated Irrigation

Agronomy, Год журнала: 2023, Номер 13(2), С. 369 - 369

Soil compaction easily causes root hypoxia stress, resulting in poor growth and the absorption of soil water nutrients. We hypothesized that aerated irrigation (AI) could enhance nutrient uptake utilization, thus unlocking high yield potential by increasing aeration morphology indicators compared with non-aeration treatment. A greenhouse experiment was conducted to investigate effect on cucumbers. The dissolved oxygen (DO) at 10 mg L−1 (A1), 20 (A2), treatment (A0) were applied via a subsurface drip system. respiration rates, DO water, morphology, crop measured. results showed AI significantly improve rate, A2 increased rate 11.63% 11.93%, respectively, A1 A0 treatments. Under A2, 20.01% 18.02%, A0. Moreover, during flowering fruit set, mature, late stages, surface area, volume, tip number, forks, dry weight than length, forks main indexes correlated yield, respectively. number influenced yield. cucumber economic benefits peaked 53.04 t ha−1 3.95 × 104 USD ha−1, 7.86% 7.30% treatment, respectively (p < 0.05). provide technical support scientific knowledge for regulating cucumbers under AI.

Root-zone aeration improves fruit yield and quality of tomato by enhancement of leaf photosynthetic performance

Agricultural Water Management, Год журнала: 2023, Номер 291, С. 108639 - 108639

Heavy irrigation and soil compaction cause hypoxic stress in plant roots, which limits crop growth. This issue can be solved by root-zone aeration, but the photophysiological responses of plants to dissolved oxygen (DO) concentration water remain unclear. Here, a greenhouse plot experiment was conducted investigate changes leaf photosynthesis growth tomato (Solanum lycopersicum L. cv. ‘Omanda 3′) under aerated with various DO concentrations. Plants were treated three different levels aeration: 5 mg L–1 (conventional subsurface as non-aeration control), 15 (low aeration treatment), 30 (high treatment). Compared control, treatments promoted electron transport from primary secondary plastoquinone acceptors (QA QB) photosystem II (PSII) increased net photosynthetic rate at seedling, fruit expansion, maturation stages. The opposite effects observed flowering fruit-setting stage. enhancement performance contributed improved growth, yield, quality result supply root zone. additionally facilitated biosynthesis carbon assimilates tissues, evidenced starch sucrose contents leaves content roots. However, high level, excessive roots hindered further improvements yield biomass Based on performance, low (15 L–1) is recommended for crops during stages, there no need

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

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 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.
