Traditional methods of raising livestock rely on the exploitation of low-quality rangelands, fallow and natural pastures with forage crops receiving little attention. The population relies on imports to meet its protein needs. Indeed, fodder production is the primary lever for improving livestock nutrition and, as a result, the productivity of the livestock systems in question. It is also crucial to the sustainability of mixed systems that combine plant and animal production. The current study was conducted to evaluate the phenological stages, analyze the performances of fodder yield, grain yield and some of its components and determine the chemical composition of the species Vicia narbonensis L. in comparison with Vicia sativa L. in order to improve the fallow year in the cereal/fallow rotation and develop the marginal lands. Trials were conducted on the plots of FERHAT Abbas University Campus under the rainfed conditions in the semi-arid region of Setif during three growing seasons (2017-2020), using 10 ecotypes of narbon vetch and 2 ecotypes of common vetch (as control ecotypes) in a randomized complete block design with three replicates. Significant effects of the ecotype, the year and the ecotype x year interaction were found, as well as a great variability in the phenological stages, agronomic characteristics and chemical composition of the ecotypes studied. A significant positive relationship (p<0.05) was found between grain yield and dry matter yield and a significant negative relationship (p<0.05) was found between full flowering date and dry matter yield and grain yield. It seems that the early flowering ecotypes produce better yields than the late flowering ones in the semi-arid region of Setif.","PeriodicalId":14882,"journal":{"name":"Journal of Agricultural Sciences, Belgrade","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135450154","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 variant, a class 1 grain was obtained while meeting other requirements of the feed lupin quality standard. This study reveals that the use of selenium contributed to increasing the collection of crude protein at the harvest of white lupin. It is assumed that selenium stimulated the processes of nitrogen entering plants and its redistribution from vegetative to generative organs, as well as activated the synthesis of proteins and their accumulation in the grain of white lupin. It was found that the content of alkaloids in the resulting crop of white lupin did not exceed acceptable levels, which allows it to be used for feed purposes and the preparation of various types of feed. The use of selenium contributed to the increase in the collection of crude protein content at the harvest of above-ground plant mass as it stimulates nitrogen processes in plants and its redistribution from vegetative organs to generative organs, as well as the synthesis of protein compounds in the lupin grain.","PeriodicalId":14882,"journal":{"name":"Journal of Agricultural Sciences, Belgrade","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78116471","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 aim of this research was to evaluate the proximate, mineral, vitamin, anti-nutrient contents of the leaves of Senecio biafrae. Leaves of Senecio biafrae were collected from five communities in Ekiti State and analyzed using standard biochemical methodologies. The results showed that the leaves differed significantly in nutritional and anti-nutritional contents. The leaves were rich in potassium, magnesium, and calcium, and low in fat and anti-nutrient contents for all the groups studied. The Pearson?s correlation results showed that most of the nutritional parameters either had inverse or no relationships with anti-nutrients. The crude protein showed significantly positive correlations with dry matter (0.90**) and a negative correlation with cyanogenic glycosides (-0.90**). Cyanogenic glycosides showed significantly negative correlations with potassium (-0.63**), calcium (-0.66**) and dry matter (-0.44*). Nitrate showed no significant relationship with any nutritional parameter. Oxalate and tannin showed no significant relationship with the vitamins. Phytate and tannin showed no significant relationship with the proximate contents and minerals. The results showed that Senecio biafrae leaf is nutrient-rich and could help to mitigate the effects of micronutrient deficiencies. The variations and relationships among the nutritional and anti-nutritional parameters could enhance meaningful selection and nutritional quality through breeding.","PeriodicalId":14882,"journal":{"name":"Journal of Agricultural Sciences, Belgrade","volume":"2 9 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88807574","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}

This industry can bring many economic and social benefits to society and the economy. The paper provides a description and analysis of the current situation within the dairy industry in our country. Milk production rates in our country are analyzed, with a comparative approach to production rates at global and European levels. In the Republic of North Macedonia, milk production is characterized by many traditional small farmers (80% of the total) with 1-3 cows and low annual milk productivity (2-3 thousand liters per cow). The number of large specialized farms with more than 15 cows (about 3% of the total) with annual milk production of about 5 thousand liters per cow is minimal. Only 1% of all farms have more than 50 cows. The Republic of North Macedonia is an absolute importer of milk and its products. The quantity and monetary value of imported milk and its products are many times higher than the quantity and value of exported milk. Today, the dairy industry faces various challenges in the three main pillars of sustainability: economic, social and environmental including fluctuating market prices, high labor costs, and demographic characteristics of the population in terms of age. In conclusion, for the dairy industry to be sustainable, all activities should be carried out in partnership with the industry (along the value chain), policymakers and a wide range of stakeholders, including consumers.","PeriodicalId":14882,"journal":{"name":"Journal of Agricultural Sciences, Belgrade","volume":"19 19-20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72493456","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}

As truffle is a natural product with nutritional and functional properties, it is important to find an optimal method for truffle storage. As the microbiota contribute to truffle aroma, the bacterial and yeast compositions in the rhizosphere and fruiting body of the truffle and the impact of different freezing methods on the volatile profile of the truffle Tuber aestivum during 90 days of the storage were determined. Bacteria and yeasts isolates were identified using 16s rRNA and 18s rRNA. The effect of freezing truffles at -20?C and -80?C with and without previous dipping in liquid N2 on the volatile compounds was observed using GC/MS. The results demonstrated that the isolated bacteria belonged to the phylum Proteobacteria, Firmicutes and Actinobacteria, and the identified species mainly belonged to Firmicutes, genus Bacillus sp. Isolated yeasts were identified as Cryptococcus sp., Debaromyces hanseinii, Candida fermentati and Rhodotorula mucilaginosa. The GC/MS analysis revealed that frozen truffle samples were richer in the compounds 2-butanone, 2-methyl-butanal, methanethiol and 2-butanol after freezing or during storage. The content of DMS, acetaldehyde, 3-octanone, ethanol, and 2-methyl-1-propanol significantly decreased immediately after freezing. Overall, the gained results indicated that freezing of truffles as a preservation method had profound effects on the volatile compounds, while previous dipping in liquid N2 showed no significant impact on the volatile profile of truffle Tuber aestivum.","PeriodicalId":14882,"journal":{"name":"Journal of Agricultural Sciences, Belgrade","volume":"149 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135447574","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}

Thus, 32 ecotypes (landraces) were assessed in the randomized complete block design layout with four replications. Positive and statistically significant correlations were determined between total dry weight (TDW) and all measured traits except for internode length (IL) [r=0.29, P>0.05]. Regarding the variance inflation factor (VIF) as a multicollinearity statistic, number of nodes per main stem (VIF=1407.4) and number of internodes per main stem (VIF=1371.6) were removed from the analysis. Path coefficient analyses indicated that number of leaflets per leaf (NLL) [0.59 direct effect], height of the longest stem (HLS) [0.42 direct effect], and dry weight/fresh weight ratio (DFR) [0.27 direct effect] were influenced by TDW as a first-order trait. Five traits considered secondary or tertiary traits affected TDW - number of stems per area (NPA), number of stems per plant (NSP), number of leaves per stem (LS), length of inflorescence (LI) and stem weight/leaf weight ratio (SLR).
