The study was conducted during 2019-2024 as part of a long-term field experiment established in 1976 at the Bila Tserkva Experimental Breeding Station in the Right-Bank Forest-Steppe of Ukraine. Four fertilisation treatments were compared in cereal-fodder-row (CFR) and cereal-row-crop (CRC) rotations: unfertilised since 1976, mineral fertilisation with straw incorporation, mineral + cattle manure fertilisation, and organic fertilisation. Soil mineral N, plant-available P, exchangeable K, OC content, and OC stocks were determined in the 0-30 cm soil layer. Crop yields were assessed for winter wheat, sugar beet and spring barley. The mineral + cattle manure treatment generally maintained favourable soil nutrient conditions and resulted in the highest OC content and stocks in both crop rotations, reaching 1.98% and 70.8 t C/ha in the CFR rotation and 1.77% and 63.2 t C/ha in the CRC rotation. However, the higher nutrient inputs under this treatment did not result in proportionally higher residual availability of all nutrients. Under sugar beet, its clearest post-harvest advantage was observed for soil mineral N, whereas exchangeable K was not consistently higher than under the other fertilised treatments, and plant-available P in the CFR rotation did not differ significantly between the mineral + straw and mineral + cattle manure treatments. The highest mean yields of winter wheat, sugar beet and spring barley were generally obtained under the mineral + cattle manure treatment. Sugar beet root yield reached 46.9 t/ha in the CFR crop rotation and 42.2 t/ha in the CRC rotation, compared with 18.8 and 17.1 t/ha, respectively, in the unfertilised treatments. The results demonstrate that combining organic and mineral nutrient sources with crop residue return and an appropriate crop rotation structure is an effective strategy for maintaining typical Chernozem fertility and sustaining crop productivity under unstable moisture conditions.

Two cultivars, cvs. Atlantic Malang and Chipita, were grown under a natural 12 h day or a 16 h day created by 4 h supplemental LED lighting until 6 weeks after planting (WAP), combined with no stem descent or stem descent at 2 or 4 WAP. A split-plot randomised complete block design with five blocks was used; daylength was the main-plot factor and six cultivar-stem descent combinations were subplots. Data were analysed by split-plot ANOVA followed by Tukey's test and principal component analysis. At 6 WAP, 16 h increased canopy, root, stolon, and early tuber growth. In cv. Atlantic Malang without stem descent, 16 h increased final tuber weight per plant by 55%. In cv. Chipita, 16 h combined with stem descent at 4 WAP reduced final tuber number and weight by 71% and 59%, respectively. Cv. Chipita without stem descent or with descent at 2 WAP produced the greatest plot-level yields. Thus, daylength extension should be matched to cultivar and stem-descent timing.

This study investigated changes in soil organic carbon (SOC), nutrient availability, cation exchange capacity (CEC), and micronutrient dynamics along a chronosequence comprising primary forest, secondary forest, and oil palm plantations aged 6, 8, 10, and 12 years in Central Sulawesi, Indonesia. SOC declined consistently following forest conversion and exhibited no meaningful recovery after 12 years of cultivation. Soil pH remained strongly acidic across all land-use categories, with progressive acidification becoming more pronounced in older plantation stands. Available phosphorus exhibited considerable spatial variability, largely governed by Fe-P interactions under acidic conditions, thereby constraining phosphorus use efficiency despite external fertilisation inputs. Exchangeable base cations, particularly Ca, accumulated progressively with advancing plantation age, yielding elevated base saturation values; however, this apparent improvement in chemical fertility was not accompanied by corresponding increases in SOC or CEC, the latter exhibiting a declining trend in older plantation soils, reflecting diminished nutrient retention capacity over time. Micronutrient analysis revealed progressive accumulation of Fe, Mn, and Cu in long-term plantation soils, suggesting potential micronutrient imbalance and phytotoxicity risks. Collectively, the chronosequence analysis indicates a discernible transition from biologically regulated forest soils to input-dependent plantation systems characterised by persistently low SOC, declining CEC, and imbalanced nutrient dynamics. These findings underscore that conventional oil palm management practices are insufficient to restore soil chemical quality and may predispose these systems to long-term degradation, necessitating the adoption of sustainable soil management strategies that prioritise the restoration of organic matter and enhanced nutrient use efficiency.

China Title: Effects of drought priming at seedling stage on salt-tolerance physiology at flowering stage and subsequent seed setting of winter wheat Abstract: To explore cultivation techniques for improving winter wheat yield in saline-alkali soils, this study investigated the effects of seedling-stage drought priming on salt tolerance and related physiological mechanisms during later growth stages. The experiment was arranged in a completely randomised design. Three soil moisture levels - 40% (W1, severe drought), 60% (W2, mild drought), and 80% (W3, well-watered) of field capacity - were applied from emergence to jointing, followed by normal irrigation and saline irrigation at 1‰ (S1), 3‰ (S2), or 5‰ (S3) NaCl. Compared with W1 and W3, mild priming (W2) significantly reduced flag leaf malondialdehyde and sterile spikelets while increasing chlorophyll and seed-setting under saline irrigation (P < 0.05). Treatment efficacy followed W2 > W3 > W1 and diminished with increasing salinity (S1 > S2 > S3). At S1, W2S1 increased stomatal conductance, superoxide dismutase (SOD) activity, and the contents of betaine and plant brassins, grains per spike (19.5%), 1 000-grain weight, and yield per plant (34.8%) versus W3S1. At S2, W2S2 increased transpiration rate, stomatal conductance, SOD activity, and the contents of soluble sugar, plant abscisic acid, and plant gibberellins, grains per spike, 1 000-grain weight, and yield per plant (35.0%) versus W3S2. Even at S3, W2S3 maintained higher SOD activity, and higher contents of osmotic substances and plant hormones (plant brassins, plant abscisic acid, and plant gibberellins), grains per spike, 1 000-grain weight, and yield per plant than W3S3. It can be seen that this advantage in seed-setting per plant is attributed to the coordinated regulation of antioxidant enzymes, osmotic substances, hormones, and photosynthesis, effectively alleviating salt stress damage. In conclusion, mild drought priming at the seedling stage establishes a stress memory that is still detectable at 7 days after anthesis (early grain filling), enhancing salt tolerance through coordinated regulation of antioxidant enzymes, osmotic substances, hormones, and photosynthesis, ultimately improving seed-setting. These findings offer a practical approach for stabilising wheat production in saline-alkali soils.
