“…These N-P, N-Mg, N-K, and N-Ca interactions confirm our previous findings (Ruseani et al 2022). Similar synergetic N-K interaction was observed in pecan (Carya illinoinensis) (Liu et al 2021), suggesting the beneficial effect of N fertilization in promoting K translocation from root to shoot. These results implied that N application can be used to mitigate K and Ca deficiency within the cocoa tissue, provided that the K and Ca are not limited in the soil.…”

We aimed to investigate variation in growth, biomass, macro-nutrient uptake, and nitrogen (N) use efficiency indices of cocoa (Theobroma cocoa L.) scion clones under two different nitrogen conditions. Ten clones were top-grafted onto 4-month-old rootstocks clone MCC 02. Each seedling received either 0 or 4.6 g of nitrogen applied as urea fertilizer. The design was arranged as a two-factor experiment with four replicates in a factorial randomized block design. We measured stem diameter, biomass, nutrient concentration, and calculated nutrient uptake, nitrogen use efficiency (NUE), agronomic efficiency (AE), apparent nitrogen recovery (ANR), and physiological efficiency (PE). We found that clones significantly affected stem diameter and shoot biomass of both rootstocks and scions. Clones differed in root magnesium (Mg) and shoot calcium (Ca) concentration, root N, and shoot Mg uptake. Furthermore, a significant clone effect was observed on ANR, with local clones showing higher ANR than introduced clones. Nitrogen application significantly improved stem diameter and biomass. Compared to unfertilized plants, a significantly higher N concentration was observed in roots, resulting in higher N uptake in both roots and shoots. Nitrogen application increased shoot Ca concentration and uptake but decreased shoot phosphorus (P) and Mg concentrations. Our results suggest genotypic variability in nitrogen uptake efficiency in clonal cocoa. Clones with high nitrogen uptake efficiency are valuable genetic resources for breeding cocoa clones that efficiently use available N and, therefore, grow better under N-deficient conditions.

“…Additionally, Gaiellales , Frankiales, and Acidobacteriales showed significant negative correlations with the TC and NO 3 − ‐N contents. These taxa are associated with the k‐strategy in microbial ecology and are members of the oligotrophic group that grows well in harsh environments with nutrient deficiency and can obtain energy via decomposition of organic material (Jiang et al, 2021; Liu et al, 2021; Xu et al, 2021). In addition, Frankiales was proven to play a role in N cycling, particularly in nitrogen fixation (Xu et al, 2021).…”

“…Specifically, trees in a rapid growth phase allocate more photosynthetic carbon and energy to fine roots than trees in a slow growth phase and alter the resources available to soil bacteria and fungi, thus recruiting different microorganisms (Tedersoo & Bahram, 2019). Soil properties, particularly pH and available nitrogen and phosphorus, are important factors influencing microbe–plant interactions worldwide (Liu et al, 2021; Liu et al, 2021; Chengjie Ren et al, 2021; Shi et al, 2021). At different ages, forests have different stand microclimates and litter biomasses and types, which could be drivers of changes in soil physicochemical properties, thus altering the soil microbial diversity and community composition (Kramer et al, 2010; Le Roux et al, 2021; Wan et al, 2021).…”

Understanding the changes in microbial communities with increasing plantation age will benefit the maintenance of forest health and productivity and the sustainable development of forest ecosystems. It was not clear before this study whether the microbial communities of pecan (Carya illinoinensis) plantations would be affected by their age. Based on MiSeq sequencing, we studied the effects of pecan age on microbial communities in rhizosphere and bulk soils of pecan plantations for the first time.The results showed that the bacterial alpha diversity of bulk soil increased significantly with plantation age (p < 0.05), while fungal alpha diversity was less influenced by pecan age in both rhizosphere soil and bulk soil. Pecan age significantly influenced

“…Whereas, excessive fertilization will result in lower N, P and K content in the soil (Li et al, 2019). Meanwhile, fertilization has significant effects on leaf functional traits (Bassi et al, 2018), such as chlorophyll content (Xiong et al, 2015), non-structural carbohydrates (Sun et al, 2020), and leaf nutrients (Liu et al, 2021). For example, Sardans et al (2017) found that in temperate forests, fertilization increased leaf nitrogen content, while the effect on phosphorus content was not significant (Sardans et al, 2017).…”

Rational fertilization is the main measure to improve crop yield, but there are differences in the optimal effects of nitrogen (N), phosphorus (P) and potassium (K) rationing exhibited by the same crop species in different regions and soil conditions. In order to determine the optimum fertilization ratio for high yield of Sapindus mukorossi in western Fujian to provide scientific basis. We carried out the experimental design with different ratios of N, P and K to investigate the effects of fertilization on the yield. and leaf physiology of Sapindus mukorossiand soil properties. Results showed that the yield of Sapindus mukorossi reached the highest value (1464.58 kg ha-1) at N2P2K2 treatment, which increased to 1056.25 kg ha-1 compared with the control. There were significant differences in the responses of soil properties and leaf physiological factors to fertilization treatments. Factor analysis showed that the integrated scores of soil factors and leaf physiological characteristic factors of Sapindus mukorossi under N2P2K2 fertilization treatment were the highest, which effectively improved the soil fertility and leaf physiological traits. The yield of Sapindus mukorossi showed a highly significant linear positive correlation with the integrated scores (r=0.70, p<0.01). Passage analysis showed that soil available nitrogen content, organic carbon content, and leaf area index were the key main factors to affect the yield. RDA showed that soil organic carbon and available phosphorus were the most important factors to affect leaf physiological traits. We recommend that the optimum fertilization ratio of Sapindus mukorossi was 0.96Kg N, 0.80Kg P and 0.64Kg K per plant. Reasonable fertilization can improve soil fertility and leaf physiological traits, while excessive fertilization has negative effects on soil fertility, leaf physiology and yield. This study provides theoretical support for scientific cultivation of woody oil seed species.
