Fertilizers are widely used to improve the quality of fruits and vegetables. However, the overuse of fertilizers has become an issue because it causes environmental problems and negatively affects productivity and fruit quality. In this study, we examined the effects of nitrogen, phosphorus, and potassium (NPK) fertilizer levels on the metabolism of cucumber fruit in low- and high-nutrient soils using mass-spectrometry-based metabolomics approaches. Cucumber metabolite content was notably different depending on the initial soil nutrient status. Most amino acids and phenylpropanoids were abundant in the cucumbers raised in low-nutrient soil, whereas organic acids, some amino acids (aspartate, glutamate, and ornithine), and carbohydrates were comparatively higher in fruits from high-nutrient soil. The fertilizer supply resulted in an alteration in the metabolite profile, while no change in fruit yield was observed in either low- or high-nutrient soils. Fertilizer treatment perturbed the metabolite contents in cucumbers from low-nutrient soil. In contrast, treatment with higher concentrations of fertilizer in high-nutrient soil increased phenylpropanoid content in the cucumbers, while most metabolites decreased. In conclusion, fertilization levels should be carefully determined, considering culture conditions such as the original soil status, to increase product yield and fruit quality and avoid environmental problems.

“…Therefore, it is imperative to assess the magnitude of agricultural GHG emissions and identify mitigation opportunities (Hu et al, 2023). GHG emissions from agroecosystems are a significant contributor to global warming (Hou P. et al, 2023). The practice of rice cultivation contributes to CH 4 and N 2 O emissions.…”

IntroductionRice, as a staple food in several Asian countries, contributes to approximately 10% of greenhouse gas (GHG) emissions during its cultivation. Furthermore, nitrogen fertilization increases the accumulation of GHG emissions. This study aims to investigate GHG emissions, including methane (CH4) and nitrous Oxide (N2O) resulting from the common fertilizer variations used by farmers in Indonesia for two rice varieties, Way Apo Buru and Inpari 32, and their relationship to rice yield. MethodsThe research was conducted from August to November 2022 in an open field located in Jember, Indonesia. Two rice varieties, Inpari 32 and Way Apo Buru, were employed in this study. Fertilization variations included Urea (46%-N), ZA (21%-N 24%-S), SP-36 (36%-P & 5%-S), KCl (250:100:50:50 kg ha-1) (P1); NPK (16%-N:16%-P:16%-K), Urea (46%-N), ZA (21%-N & 24%-S) (225:175:100 kg ha-1) (P2); NPK (12%-N:12%-P:17%-K), Urea (46%-N), ZA (21%-N & 24%-S) (175:150:100 kg ha-1) (P3); and NPKS (P1) + chicken manure fertilizer 5 tonnes ha-1 (P4).ResultsIn this research, Inpari 32 rice achieved greater yields while also exhibiting higher global warming potential. Applying NPKS fertilizer in combination with 5 tonnes ha-1 of manure fertilizer (referred to as P4) resulted in a substantial increase in rice yield compared to alternative fertilizer formulations. DiscussionsThe various inorganic fertilizers had a relatively similar influence on growth, production yield, and greenhouse gas emissions (CH4 and N2O). However, the fertilizer NPKS and 5 tonnes manure fertilizer resulted in the lowest CH4 emissions and global warming potential values.

“…In the last 100 years, the application of chemical nitrogen (N) fertilizers has promoted crop production by more than four times and contributed greatly to global crop production and food security [1]. However, excessive chemical N fertilizers that greatly exceeded the normal N requirements of crops were applied by farmers for the purpose of increasing crop productions during the last two decades, resulting in decreased quality and yield of crops and excessive N accumulation in soil.…”

The substitution of chemical nitrogen (N) fertilizer with organic fertilizer (organic substitution, OS) is increasingly applied in crop production, due to its environmentally friendly characteristics, low price, and high crop and soil improvement efficacies. Here, we studied the effects of chemical N fertilizer with organic fertilizer treatment at different proportions (no organic substitution (NOS), 20% (OS-20), 40% (OS-40), 60% (OS-60), 100% (OS-100), and 200% (OS-200, double the organic fertilizer application amount of OS-100) on the yield and quality of apples in the Shanxi Province of China. The results revealed that, compared to the NOS, the total apple yields of OS treatments, especially the OS-60 and OS-100 treatments, decreased. However, all OS treatments, except OS-200, increased the yield of large-sized fruits (transverse diameter ≥ 85 mm) and the mean mass of apple fruits, and significantly decreased yield of small-sized fruits (transverse diameter < 75 mm). All OS treatments, especially OS-40, promoted the total sugar and vitamin C (Vc) contents and fruit hardness of apples, and OS-40, OS-60, and OS-200 resulted in significantly decreased titratable acid contents in apples. The influence of organic substitutions on soil quality was further investigated in a two-year field experiment. The results showed that the influence of organic substitution on soil chemical properties differed between the two years. Notably, 40% OS increased the soil organic carbon (SOC) content and the C/N ratio in the upper 20 cm of the soil in both years. Additionally, OS treatments reduced the residual nitrate (NO3−)-N (RN) content in deep soil layers, suggesting that OS has the potential to alleviate N leaching. Moreover, redundancy analysis (RDA) of the soil, fruit yield, and fruit quality parameters revealed that the SOC content in the 0–20 cm soil layer and the RN content in the 0–100 cm soil layer had the greatest impact on the fruit quality and yield variables, respectively. This study showed that the proper substitution (40%) of chemical N fertilizer with organic fertilizer could improve the yield of large-sized fruits, the mean mass and fruit quality of apples, and soil chemical properties. Our study will provide a basis for rational organic substitution in apple orchards.
