Cabernet Sauvignon). However, the ecological mechanisms underlying the mulching materials were not well understood. This study aimed to evaluate the effects of different mulching materials on soil chemical properties, bacterial community and wine grape quality. Experiments were performed at a grape-yard on the six-year-old wine grape ‘Vitis vinifera L. cv. Cabernet sauvignon. Five kinds of mulching materials include living turfgrass (Grass), living Herba portulacae (Por), inorganic plastic black film (Film), organic chips of wood (Wood), and grape branches (Branch) were applied, while clean tillage (CK) was treated as a control. Soil chemical properties and grape quality indicators were measured. Soil bacterial community diversity was detected using the Illumina Miseq sequencing for the 16S rRNA gene V3-V4 region. Mulching with plastic film, wood chips and Herba portulacae (Por) increased the content of soil organic matter, available N, P and K, total N and P. Film, grass, branch and Por mulching materials improved the content of tannin, anthocyanin, total phenol and titratable acid in grape (p<0.05). Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteria and Gemmatimonadetes were abundant bacteria. Mulching with grape branch and portulacae increased the relative abundance of Gemmatimonadetes and Chloroflexi phylum, Gemmatimonadaceae family, and decreased Micrococcaceae family and Pseudarthrobacter genus. Mulching with living, organic, or inorganic changed chemical properties and grape quality indicators. These changes might be correlated with the altered soil bacterial community diversity and richness. © 2022 Friends Science Publishers","PeriodicalId":13769,"journal":{"name":"International Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42546228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Toxic effect was observed to be dependent on dose as well as exposure-time. No significant differences were observed between L. camara, R. sricta and positive control fipronil 2.5EC. Moreover, L. camara and R. stricta extracts, at 500 mg.kg-1, showed potential repellent effects on P. hybostoma (Desneux) with repellency of 88.3 and 81.67%, respectively.

The trial, which lasted eight weeks, used a total of hundred and eighty fingerlings. In a Completely Randomized Design, four treatment groups were randomly selected, each with fifteen (15) fingerlings and each treatment was reproduced three times (CRD). The following treatments were created using four isonitrogenous (32 percent crude protein) and isocaloric (356 kcal DE/100 g) diets, control (C) had no MLM, but MLM was utilized to replace DORB at 10 percent (T1), 20% (T2) and 30% (T3), respectively. Both muscle and liver alanine aminotransferase (ALT) activities were considerably elevated (P < 0.05) in the MLM 20% group. There were also significant increases in hepatic superoxide dismutase (SOD) and catalase activity (P 0.05) in the MLM20 and MLM30 groups. There was no significant difference between treatments in serum albumin concentration, total protein, or the ratio albumin/globulin (P > 0.05). MLM20% and MLM30% groups had substantially higher Nitroblue Tetrazolium (NBT) values than the other MLM fed groups (P < 0.05). As a result, the study concludes that mucuna leaf meal derived from M. bracteata can fully replace DORB in the diet of C. carpio without causing any negative effects, while 20% MLM inclusion offered additional benefits. © 2022 Friends Science Publishers","PeriodicalId":13769,"journal":{"name":"International Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45215820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the contents of carotenoids in two yellow flesh peach varieties ('Zhongtao Jinmi' and 'Jinxiang') and one white flesh peach variety ('Bairuyu') were determined by high-performance liquid chromatography. The results showed that the carotenoid content in the two yellow flesh peach varieties increased with fruit development and reached the maximum of 25.80 and 27.63 μg.g-1 at the mature stage, while that of the white flesh peach variety remained at a very low level during the whole fruit development period. Furthermore, transcriptome sequencing was performed to analyze the differentially expressed genes (DEGs) during fruit development among the three peach varieties. Among these DEGs, four candidate genes were identified to be potentially involved in the biosynthesis of carotenoids, including LOC18774744 (encoding UDP-glycosyltransferase 87A1 (UGT87A1)), LOC18792568 (encoding the carotenoid cleavage dioxygenase 4 gene (CCD4)), LOC109949966 (an unannotated gene), and LOC18779468 (encoding xyloglucan endoglucosylase/hydrolase protein 8. qRT-PCR confirmed that the expression of LOC109949966 and LOC18779468 in two yellow flesh varieties was significantly higher than that in the white flesh variety, while it was the opposite case for UGT87A1 and CCD4. Therefore, we speculate that CCD4 is directly involved in regulating carotenoid synthesis, while other three genes may play some indirect roles in the process. Our findings are expected to improve the understanding on the mechanism of carotenoid biosynthesis in peach. © 2022 Friends Science Publishers","PeriodicalId":13769,"journal":{"name":"International Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46034066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(Convolvulaceae), known generically as morning glory, is an important invasive plant introduced in Brazil, which not only causes significant losses in annual crops, but also makes harvesting difficult and already presents herbicide-tolerant biotypes in the country. In this context, alternative and sustainable ways of managing this plant are sought. The objective of this work was to evaluate the effect of neem oil on morning glory seeds and seedlings. The experiment was carried out in a completely randomized design, with six treatments composed of different oil dilutions, applied before and after germination, in addition to the control. Based on the experiment, it was observed that neem oil delayed seed germination by up to 1.4 days, although without significance. On the other hand, seedling fresh weight was severely affected by application after sowing, leading to a symptom of leaf blight. Morning glory seedling survival followed the same pattern, where there was a significant reduction by the application of neem oil only after sowing. It was concluded that neem oil has a phytotoxic effect on I. purpurea seedlings, reducing their survival and fresh weight when applied after germination, as well as influencing (delaying) seed emergence when applied to the soil. The study of the effect of lower concentrations, close to economically viable and practiced in the field, should be carried out in the future. © 2022 Friends Science Publishers","PeriodicalId":13769,"journal":{"name":"International Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44332993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study evaluated the influence of different N application rates and planting density on the yield and N utilization efficiency of direct seeded rape during the 2016–2017 and 2017–2018 growing seasons. The three N application rates including 108 kg N ha−1, 144 kg N ha−1 and 180 kg N ha−1 were laid out into main plots while planting density including 15.0 × 104, 22.5 × 104, 30.0 × 104 and 37.5 × 104 plants ha−1 respectively into sub-plots. The results showed that suitable planting density was the premise to gain high rapeseed yield and the contribution of planting density to rapeseed yield was small when it surpassed a certain value. The highest yield in the two growing seasons was achieved at 144 kg N ha−1 with planting density of 30.0 × 104 plants ha−1. The rapeseed yield increased linearly as N uptake of the seed part increased, but at high planting density, there was no increase in yield with the increase N uptake of non-seed parts (stem + husk) when rapeseed yield exceeded a certain value. High planting densities raised shoot N uptake and N transfer to rapeseed seeds with the increase of density and N utilization efficiency was also improved. The too much N application resulted in more N accumulation in non-seed parts without increasing production. Under the same target yield, the increased planting density can save 32.4–65.7% of N fertilization compared with the conventional planting density. The combination of different N fertilization rates and planting densities is helpful to increase rapeseed yield. The best N management strategy is to achieve high yield and reduce the environmental risk to reduce the N fertilization at suitable high density. © 2022 Friends Science Publishers","PeriodicalId":13769,"journal":{"name":"International Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47306426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study reports the characterization of two multifunctional bacterial strains Bacillus sp. SG36 and Bacillus sp. SG42, which have the potential not to promote the growth of plants in soil under stress due to reactive yellow 2 (RY2) dye but also the capability to cope with this dye through its decolorization. The strains were isolated from a rhizospheric soil repeatedly contaminated with colored textile wastewaters. Both the strains had optimal RY2 decolorization potential at slightly alkaline pH (7.5) and even in the presence of significant amount of NaCl (50 g L-1) in the medium. The strains harbor the phosphorus solubilization and indole acetic acid production potentials in concurrence with decolorization of RY2. In a pot experiment, the strains SG36 and SG42 were found to significantly promote the growth (Shoot/root length, shoot/root fresh weight) of mung bean (Vigna radiate) in non-contaminated and RY2 contaminated soils in parallel with RY2 decolorization in the soil. © 2022 Friends Science Publishers","PeriodicalId":13769,"journal":{"name":"International Journal of Agriculture and Biology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43610421","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
