“…Fruit color was measured with a portable colorimeter (3NH SR-66; Shenzhen 3NH Technology Co., Ltd., Shenzhen, China). Color coordinates were recorded as L*, a*, and b* [ 2 ]. Soluble solids were measured using a pocket brix-acidity meter (Cat.…”

“…Blackberry fruits are rich in sugars, VC, superoxide dismutase (SOD), anthocyanins, ellagic acid, flavonoids, carotenoids, amino acids, and other mineral nutrients [ 1 ]. Because of their rich nutrition and unique taste, they have been recommended as the third generation of emerging small berries by FAO [ 2 ]. Souza et al [ 3 ] found that blackberries had the highest antioxidant activity and phenol and anthocyanin content compared to other berries such as red raspberries, strawberries, cherries, and blueberries, even among different varieties.…”

“…N not only affects the vegetative growth of plants, but also plays an important role in regulating fruit quality [ 2 , 18 ]. Yang et al [ 2 ] found that rational application of N fertilizer could significantly promote photosynthesis in blackberry plants and increase fruit yields and anthocyanin, polyphenol, and ellagic acid contents. Ali et al [ 18 ] observed that when N fertilizer application increased from 60 kg ha −1 to 100 kg ha −1 , the pH value and soluble solid, sugar, and anthocyanin contents of blackberry fruits increased significantly.…”

To study the optimal form of nitrogen (N) application and to determine the best harvest date for blackberries, different N fertilizers were applied during the critical growth period of blackberry plants. The results showed that NH4+–N significantly improved the appearance of blackberry fruits, including their size, firmness, and color, and promoted the accumulation of soluble solids, sugars, anthocyanin, ellagic acid, and vitamin C (VC), while fruit treated with NO3−–N accumulated more flavonoids and organic acids and had improved antioxidant capacity. In addition, the fruit size, firmness, and color brightness decreased with the harvest period. While the contents of sugars, anthocyanin, ellagic acid, flavonoids, and VC were higher in the early harvests and then decreased as the season progressed, the total antioxidant capacity and DPPH radical scavenging capacity increased. In all, application of NH4+–N is recommended, as it is more beneficial to fruit appearance, taste, and nutritional quality. Harvests in the early stage help to obtain a good fruit appearance, while harvests in the middle and later stages are more beneficial to fruit taste and quality. This study may help growers to determine the best fertilization scheme for blackberries and choose the appropriate harvest time according to their needs.

“…Previous studies have confirmed that rational nitrogen fertilization can significantly increase the yield of rice ( Oryza sativa L.), wheat ( Triticum aestivum L.), sorghum ( Sorghum bicolor L.) and other crops ( Li et al, 2022c ; Liao et al, 2022 ). However, unreasonable nitrogen application will not only reduce the yield and quality of crops, but also cause serious adverse problems, including increasing of production costs, higher soil acidification, reduced quality of cultivated land and environment pollution ( Liu C. Y. et al, 2021 ; Yang Y. et al, 2023 ). A better understanding on the rational nitrogen fertilizer amount and theories of nitrogen use may contribute to improve crop yield.…”

Tartary buckwheat (Fagopyrum tataricum Gaertn.) is an important pseudocereal crop with excellent edible, nutritional and medicinal values. However, the yield of Tartary buckwheat (TB) is very low due to old-fashioned cultivation techniques, particularly unreasonable application of nitrogen fertilizer. To improve the understanding on the theories of nitrogen use in TB, the effects of nitrogen application on growth, as well as chemical properties and microbial community of rhizosphere soil were investigated in this study. Nitrogen application could promote the plant height, stem diameter, nitrogen accumulation and yield of TB. The relative abundance and diversity of bacteria and fungi in the rhizosphere soil of TB were improved by nitrogen fertilizer. Nitrogen application increased the abundance of beneficial bacteria such as Lysobacter and Sphingomonas in rhizosphere soil, and decreased the abundance of pathogenic fungi such as Fusarium and Plectosphaerella. The results indicated that nitrogen application changed the distribution of microbial communities in TB rhizosphere soil. Furthermore, the specific enriched or depleted microorganisms in the rhizosphere soil of four TB varieties were analyzed at OTU level. 87 specific nitrogen-responsive genes with sequence variation were identified in four varieties by integrating genomic re-sequencing and transcriptome analysis, and these genes may involve in the recruitment of specific rhizosphere microorganisms in different TB varieties. This study provided new insights into the effects of nitrogen application on TB growth and rhizosphere microbial community, and improved the understanding on the mechanisms of TB root–microbe interactions.
