They are widely varied and include several important crops, which are mainly used as sources of fibre, food and beverages, medicines, timber. The species of the family Malvaceae: annual, Malva crispa and Malva meluca, native to East Asia, and perennial, Sida hermaphrodita, from North America, grown in monoculture in the experimental land of the Botanical Garden (Institute), served as subjects of the research, and the traditional crop Medicago sativa was used as control. The importance of the studied species of the family Malvaceae consists in their very rapid emergence and fast growth. The analysis of the chemical composition suggested that the dry matter of the studied species, at the 1st mowing contained 15.67-21.67 % raw protein, 2.15-4.46 % raw fats, 8.35-11.53 % minerals and 34.74-40.66 % nitrogen free extract, Medicago sativa - 17.03 %, 2.30 %, 33.31 %, 8.01 % and 39.41 % respectively, making them good candidates for use as livestock feed and for biomethane production. The nutritive value of 100 kg fresh mass of the studied Malvaceae species was 14.9-16.6 nutritive units and 153-173 MJ metabolizable energy, a nutritive unit contained 154.2-191.0 g digestible protein with high concentrations of limiting amino acids, the control - 21 nutritive units, 228 MJ and 164.3 g digestible protein, respectively. The calculated capacity of biomethane production of the studied Malvaceae species can reach 231-267 l/kg organic matter, Medicago sativa - 248 l/kg organic matter. The theoretical ethanol yield from structural carbohydrates of the dry biomass of stalks averaged 437-527 L/t in Malvaceae species, as compared to 485 L/t in corn. The best results were achieved by Sida hermaphrodita, due to its high amount of structural carbohydrates. These species may serve as feed for livestock, but also as multi-purpose feedstock for biorefinery in Moldova.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"68 1","pages":"126 - 133"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82352890","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 the same time, the effect of foliar fertilization on increasing the efficiency of nitrogen use by biostimulating the plant up-take was highlighted. Urea and ammonium nitrate labeled with 15N isotope (10% from total nitrogen content of the fertilizers being covered by 15N isotope) were incorporated in soil. In order to highlight the efficiency of foliar fertilization, fertilizers having NPK matrix with mezo and microelements and proteic organic compounds (animal and vegetal) were designed and obtained. The effects of experimental treatments on isotopic indicators (15N/14N isotopic rate, δ 15N isotopic accumulation degree, 15N isotope export, absorbtion degree of 15N isotope) from plant were assessed. The tested plant was maize (Cortes hybrid). The values obtained were statistically analyzed by using variance analyze, with two factors, Duncan test of multiple comparison, multiple comparison threshold α= 0.05. The results of agrochemical testing showed that the absorbtion degree of 15N isotope from soil into maize plant was highest for the amidic (N-NH2) form of the nitrogen comparing with the other forms (N-NO3, N-NH4).","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"73 1","pages":"86 - 92"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86913645","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}

Alternative ways for fungal contamination control involve natural products, based on microorganisms, many of them being already available for use. The selection and characterization of new biological agents useful for plant pathogens control are permanent goals for plant protection researches. In the last decade, several studies revealed that Streptomyces species are promising biocontrol agents against a wide range of phytopathogenic fungi, including Fusarium spp., one of the most important wheat pathogens. In our study, 60 strains of Streptomyces spp. were isolated from soil or compost and evaluated for in vitro antifungal abilities by dual confrontation method. At least 30% of the isolates presented inhibitory activity against F. culmorum and F. graminearum. The bacterial strains were also tested for their ability to produce various bioactive compounds, possible involved in fungal inhibition. The capacity of some of the bacterial isolates to produce cellulases, amylases, lipases and volatile metabolites was proved. In addition, a new screening method for chitinases production was developed, based on the use of a combination of Congo red and Lugol solutions, which allowed the detection of chitinases in several Streptomyces spp. strains. Moreover, the reduction of the level of some Fusarium mycotoxins was detected by HPTLC analysis. As a conclusion, antagonistic interactions between Streptomyces isolates and fusaria could involve antibiosis, competition and parasitism and suggested that at least some of the selected isolates could be used in obtaining biological control products.","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"18 1","pages":"594 - 600"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82605126","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}

Soils have been collected from forested areas of Lake Region. The isolated bacteria have been tested at the conventional farm in Mediterranean region. Nine isolated and one cocktailed bacteria suspensions have been applied to rhizosphere of corn plants under regular cultivation practices in conventional production systems. The results revealed that all isolates are showing either positive or negative effect on both plant performance and nutrient uptake. No statistical differences were observed on grain yield; however, Isolates 3 and 9 showed improved grain-excluded biomass performances by 37.1% and 38.5% respectively. Phosphorus, zinc and manganese uptakes were the highest in Isolate 6 whereas the highest Fe uptake was determined in Isolate 8 at the tuft formation stage. Although all isolates represent their specific individual performances as far as any plant nutrient uptakes are concerned, their cocktail was not as effective.

Among the variables of the terroir, the clone of Feteasca neagra is also a factor. Thus, in Murfatlar region we find either clone 9Mf or the massal selection, in Stefanesti clone 4VI is planted, while in Pietroasa and Bucharest clone 10Pt is cultivated. To assess the behaviour of the variety in different wine regions physico-chemical analyses of the grapes were performed, along with the determination of the uvological and phenolic maturity parameters. The results show a high variability, induced both by the cultivation conditions and the selected clone. Although the harvesting was done at approximately the same date, differences in all assessed parameters are found to be directly dependent on the clone, even in the case of the cultivation in the same region (Murfatlar), while the same clone (10Pt) shows a different behaviour when cultivated in separated regions (Pietroasa or Bucharest). The most important characteristics of the grapes are presented and discussed, with a special emphasis on the parameters related to phenolic maturity, which are the most important for the colour and aging potential of the wines. The other compositional parameters are discussed as well, as they also influence the wine’s balance. The favourability of the different regions for the cultivation of Feteasca neagra is assessed, taking into account the wine style which can be obtained from the raw materials, such as wines destined for aging or wines suitable for consumption while young","PeriodicalId":6413,"journal":{"name":"“Agriculture for Life, Life for Agriculture” Conference Proceedings","volume":"7 1","pages":"238 - 243"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77830186","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}

Increasing the activated sludge concentration in a wastewater treatment plant is an effective method by altering the process dynamics and by reducing the produced sludge volume. There are proposed and discussed in terms of technical and cost efficiency different technological wastewater treatment schemes.
