“…According to Margenot et al (2017) , declining P availability in ASSs is due to the immobilized P that was precipitated by Al and Fe ions to create insoluble compounds (AlPO 4 and FePO 4 ). These forms of P are not easy for plant uptake and accumulation ( Ngoc et al, 2022 ). Many previous studies have demonstrated that there is a significant positive correlation between soil available P and sweet potato yield ( Kareem et al, 2020 ; Liu et al, 2022 ; Mugai, Mworia & Martin, 2022 ).…”

The available phosphorus (P) in acid sulfate soils (ASSs) is low because of fixation by aluminum (Al) and iron (Fe), resulting in decreased P use efficiency and crop yield. At present, the use of dicarboxylic acid polymer (DCAP) coated on P fertilizer is expected to improve P use efficiency and plant productivity. However, the influence of DCAP on P solubility and on the yield of sweet potato cultivated in acidic soils has not been elucidated. Thus, the aimed of this study was to evaluate the effect of the use of DCAP-coated P fertilizer on the availability and nutrient uptake of P as well as the yield of sweet potato. Under the greenhouse condition, the use of DCAP significantly improved P availability (~3 mg P kg−1), increasing tuber diameter and length by ~0.5 and ~1.0 cm, respectively. Thus, the productivity of sweet potato in the treatment 40-kg P2O5 and 60-kg P2O5 ha−1 coated with DCAP was higher by about 100 g pot−1 than that in the same rate of P fertilizers (40- and 60-kg P2O5 ha−1) not coated with DCAP. In the field experiment, P accumulation (82.7 kg P2O5 ha−1) and tuber yield (22.0 t ha−1) in the treatment of DCAP-coated with 60-kg P2O5 ha−1 were not significantly different compared with that in the treatment of 80-kg P2O5 ha−1 (82.1 kg P2O5 and 21.7 t ha−1, respectively). Furthermore, the use of DCAP combined with 75% P fertilizer increased the P availability by the same amount as that with the use of 100% P fertilizer. Hence, the use of DCAP reduced about 25% of the chemical P fertilizer applied in soil.

“…In combination with other environmental factors, its effect on a plant’s resource metabolism and assimilation varies based on species [ 3 ]. Multiple environmental factors, such as soil and air temperature, soil moisture, and fertility, induce morphological and resource allocation plasticity in the Vaccinium genus, but very few studies have focused on its response to increasing shade [ 2 , 4 , 5 ]. Members of the Vaccinium genus, including 25 species such as cranberries and blueberries, have phenotypic plasticity that can be attributed to the canopy covers (shade) of a typical boreal forest [ 4 ].…”

We studied the effect of shade on the phenology, growth, berry yield, and chemical content of two common blueberry species (Vaccinium myrtilloides and V. angustifolium) in Northwestern Ontario. We hypothesized that high shade would delay vegetative and reproductive phenology and decrease berry yield by increasing resource allocation to vegetative vs. reproductive growth, whereas moderate shade would increase berry phenolic content and antioxidant capacity. We subjected transplanted blueberry plants to a controlled shade treatment and evaluated plant phenological events, vegetative and reproductive growth, berry phenolics, and antioxidant capacity. High shade caused an earlier leaf maturation in V. myrtilloides, delayed flowering in V. angustifolium, and prolonged fruit maturation in both. The berry yield of both species decreased with increasing shade. High shade reduced the berry phenolic content and antioxidant capacity, especially in V. myrtilloides. We concluded that shade shifts species-specific vegetative and reproductive phenology, leading to a difference in resource acquisition, resulting in lower berry yield and antioxidant activity.

Background: The Mekong Delta features acidic clay soil of alluvial origin with a soil texture ranging from silty clay to clay. The growth of wild blueberry plants in clay soils requires the addition of materials to enhance soil porosity and aeration. Objective: The objective of this study was to examine the effects of the combined use of biochar and compost on the growth, yield, and NPK uptake of blueberry ( Vaccinium tenellum) cultivated in the Mekong Delta. Methods: The pot experiment had a 3 × 3 factorial design, containing the application of biochar at 0, 10, and 20 t ha -1 (B0, B10, and B20, respectively), compost at 0, 5, and 10 t ha -1 (C0, C5, and C10, respectively), and NPK at 45:20:20 kgha -1 according to the growth stages of blueberries. Results: The interaction between biochar and compost provided a more efficient response in terms of plant growth, yield, and NPK uptake. Notably, in the combined application of B20 and C10, NPK uptake and biomass of blueberries were significantly increased. However, only the concentration (gkg -1) of N (14.8) and K (3.82), except for P (1.37), in the blueberry leaves were below the Trevett threshold. Conclusion: This approach effectively mitigates the challenges posed by high clay content in the soil, which results in poorer soil porosity and aeration. The findings emphasize the potential benefits of tailored soil amendment strategies to optimize blueberry cultivation in similar environments.
