Land degradation and extensive use of agricultural lands have led to the decline in soil fertility. To reverse the nutrient deterioration of cultivated lands, farmers have started employing various conservation agriculture practices. This study was initiated to examine the potential of conservation agriculture (integrated practices such as inter cropping, crop rotation, residue retention and minimum tillage) by smallholder farmers to enhance soil organic carbon stock and other selected soil physicochemical properties in Akaki district Bilbilo micro watershed. A systematic sampling method was employed for data collection. Totally 96 composite soil samples (8 plots x 2 systems x 2 replication of site x 3 depth: 0-10cm, 10-20cm and 20-30cm) were collected for analysis. Results showed that soil bulk density (BD) was significantly (p<0.05) varied with practices and depth (p<0.001). It was lower in soil under conservation (0.78 g m-3) than under conventional practice (1.48 gm-3); and in the top layer 0-10 cm (1.21±0.05) than the rest depths. BD showed increasing trend with soil depth across the practices: lower on the top 0-10cm depth (0.78 ±0.03) compared with the rest. The pH was higher (7.28) in conservation than conventional (5.75). The CEC was higher (14.6Cmol (+)/kg) in conservation practice than in the conventional (10.3 cmol (+)/kg). Both pH and CEC had shown increase in the two practices and soil depth due to the leaching of base cation from upper to lower layers. The mean SOC stocks decrease with increasing soil depth about the significant variations with treatments and depth. The SOC stock was higher (110.6t c /h) in conservation practice than in conventional practice (50.22 t/ha). Similarly, total N stocks was also higher (19.5 t c/ha) in conservation practice than in conventional practice (17.4 t c/ha). SOC and total N in both practices had decreased with soil depth due to lower accumulation of organic residue in the lower layer. Likewise, C: N ratios had increases with depth due to similar reason the decrease the amount of soil organic carbon and TN pool (e.g. root biomass) with depth. However, the C: N ratio has higher value in conservation practice (6.51) than in conventional practice (6.05). Most of the measured soil properties were improved in CA aided followed by soil depth compared with conventional agriculture and at soil depth layers ones. The interaction of farming practice types and soil depth also significantly affected all parameters.

“…Blueberries, bilberries, cranberries and other berries are fleshy berry fruits with the high levels of bioactive compounds, especially anthocyanin pigments. Besides anthocyanins, phenylpropanoid and flavonoid pathways, these berries also contain other secondary metabolites of interest, such as carotenoid derivatives, vitamins and flavour compounds produced by volatile organic compounds (VOCs) . VOCs are responsible for the aroma of berries in a genus‐ and species‐specific way and also obtained through the biosynthetic pathways.…”

Berries have many biological and physiological functions such as antioxidant, antibacterial and anti-inflammatory, and become a more popular food in China. Water-soluble polyphenols are their main functional active substances, and aroma components contribute to the flavour. The contents of total phenol and volatile organic compounds (VOCs) in ten berries grown in Northeast China were determined. Their antioxidant and antimicrobial activities were also investigated. Ribes rubrum L. and Rubus glaucus showed a higher antioxidant capacity. Ribes rubrum L. and Lonicera caerulea have a broader antibacterial spectrum. There is a correlation between the content of hydroxyl compounds in radical antioxidant activity. The metabolic pathways of polyphenols and VOCs are correlated, indicating a rapid evaluation of the biological activity of berries using the determination of volatile components.

Bilberry (Vaccinium myrtillus L.) fruits are an excellent natural resource for human diet because of their special flavor, taste and nutritional value as well as medical properties. Bilberries are recognized for their high anthocyanin content and many of the genes involved in the anthocyanin biosynthesis have been characterized. So far, neither genomic nor RNA-seq data have been available for the species. In the present study, we de novo sequenced two bilberry fruit developmental stages, unripe green (G) and ripening (R). A total of 57,919 unigenes were assembled of which 80.2% were annotated against six public protein databases. The transcriptome served as exploratory data to identify putative transcription factors related to fruit ripening. Differentially expressed genes (DEGs) between G and R stages were prominently upregulated in R stage with the functional annotation indicating their main roles in active metabolism and catalysis. The unigenes encoding putative ripening-related regulatory genes, including members of NAC, WRKY, LOB, ERF, ARF and ABI families, were analysed by qRT-PCR at five bilberry developmental stages. Our de novo transcriptome database contributes to the understanding of the regulatory network associated with the fruit ripening in bilberry and provides the first dataset for wild Vaccinium species acquired by NGS technology.
