Enriching soils with composts and organic waste material will be necessary because high C soils have strong climate change resilience and guarantee stable yields. Annually ≈1 billion tons of agricultural waste is produced which can be brought back to soils after adequate treatment and can relieve atmosphere from CO2. In a field trial municipal solid waste compost (MSW), sphagnum peat (WT), and black peat (HT) were tested. Basic soil parameters pH, C-content and plant nutrients (K, Mg) are significantly increased by MSW. WT and HT were uninfluential. Similar effects are found for microelements Fe, Mn, Zn, and Cu. MSW increased microelements significantly.

In viticultural ecosystems, considered energy-intensive systems, the amplification of biocoenotic imbalances with the onset of pest explosions, is a problem and also an evidence of the biodiversity’s decline. In this study the biodiversity was quantified in Târnave vineyard, in the period 2016-2018, in the experimental plots of SCDVV Blaj cultivated with the Fetească regală cultivar, for two cultivation technologies, the extensive agroecological (EA) and the intensive conventional (IC). The determined biodiversity characterization indicators were: the species richness, Simpson biodiversity index (D), Shanon biodiversity index (H) and Equity index (E). In case of the Heteroptera group EA technology doubled the number of the arthropods (11.333 ± 0.882 for EA versus 5.33 ± 1.453 for IC). The reverse effect was observed for Coleoptera were in the case of EA it was found a taxa richness of 8.667 ± 0.882 and for IC one of 15.667 ± 1.764. Considering the increase of the number of useful species from the order Heteroptera in the agroecological variant compared to the conventional variant, we consider that the implementation of the agroecological technology for a longer period (5-10 years) can be a long-term solution that will contribute to reducing the risk induced by the intensive practices, while reducing the dependence of culture on conventional energy resources.

This study was carried out to analyse the market participation and consumption of Vigna unguiculata in Ibadan Metropolis of Oyo State, Nigeria. Primary data were collected from a total of 300 households in 4 Local Government Areas of the State using multistage sampling technique. Data were analysed using descriptive statistics and double-hurdle regression model. Age of household head, sex of household head, marital status, years of household head education and primary occupation of household head influenced market participation while years of education, total expenditure, price of cowpea and its attributes such as weevil damage tolerance and presence of foreign particles influenced consumption of cowpea. This study recommends that for consumers to participate in the market and consumption of cowpea, then research and breeding institutes should endeavor to develop cowpeas with the required qualities; and that policy makers should target policies that are pricing-related through subsidization.

To reduce economic losses caused by viruses and phytoplasmas, one of the main preventive measures is to use 'certified' plant material. A nuclear-stock plum collection under insect-proof house is conserved at FRDS Bistrița and consists in twenty-one varieties and one rootstock used for stone fruits propagation. A widening of Romanian plum varieties at Pre-basic category is required to create the opportunity to establish a larger national valuable nuclear-stock collection and to secure the prerequisite for a good transfer of Romanian plum breeding results to the practical application. Plants belonging to other six Romanian plum varieties (Diana, Silvia, Tita, Pescăruș, Gras românesc and Tuleu dulce) were monitored in the field along two consecutive years for potential viral symptoms and tested by serological and molecular tools according EPPO standards. Selected trees of each variety were grafted onto virus-free Saint Julien rootstocks, into insect-proof house, and retested. Three grafted plants from each of the six varieties were chosen to become Candidate Pre-basic material and they were biological indexed onto virus free plants of GF 305. Thus, candidate Pre-basic material, the precursor for Pre-basic category, was established to other six valuable Romanian plum varieties.
为了减少病毒和植物原体造成的经济损失，主要的预防措施之一是使用“认证”的植物材料。在FRDS Bistrița保存了一个防虫房下的核砧木李子，包括21个品种和1个用于核果繁殖的砧木。罗马尼亚李子品种的扩大需要在前基础类别创造机会，建立一个更大的国家有价值的核储备，并确保罗马尼亚李子育种成果向实际应用的良好转移的先决条件。另外6个罗马尼亚李子品种(Diana、Silvia、Tita、pesccreatrucu、Gras rom nesc和Tuleu dulce)连续两年在田间监测潜在的病毒症状，并根据EPPO标准通过血清学和分子工具进行检测。选择每个品种的树木嫁接到无病毒的圣朱利安砧木上，进入防虫房，并重新测试。从6个品种中各选择3个嫁接植株作为候选Pre-basic材料，并与GF - 305脱毒植株进行生物学标记。由此，确定了候选的Pre-basic材料，即Pre-basic类别的前体，与其他6个有价值的罗马尼亚李子品种相比较。

The aim of this study was to assess phenotypic diversity in terms of fruit quality traits and yield, and also to establish valuable genotypes for breeding purpose suitable for different direction of use. Ten cultivars of hot peppers bred at VRDS Buzau were collected and fruit quality (dry matter content, fruit firmness, the total soluble solids, titratable acidity and ascorbic acid content) was evaluated at different ripening stages. A very highly significant difference (p<0.01) was found for the studied quantitative parameters, showing a great variability among the studied accessions. During ripening, the dry matter content, the firmness, the TSS content and the titratable acidity increase for all studied cultivars and there were significant differences between them. A broad range of variation was noted in Vitamin C content in both stages of maturity. In the present research work, a great variability among the studied accessions was found. Fully ripe fruits were found considerably richer in the bioactive factor than unripe fruits. Our results have selected two important genotypes: A12A, an accession suitable for obtaining chili powder, due to the his low content in dry matter and total soluble solids and accession A135 suited for fresh consumption and for long shelf life because it has a high firmness.

While cotton cultivation is considered as the main cash crop for Greece, cultivation practices and their environmental-friendly level are the focus of recent research. Research is examined the main sources for greenhouses gases in cotton cultivation. Until now, crop cultivation stimulates greenhouse gas (GHG) emissions only from soil. For this reason, main sources are found to be agricultural practices such as irrigation and fertilization. It is imperative to be estimated sources of greenhouses emission in cotton cultivation for the territory of Greece. The present study takes into account all the factors related to the cotton cultivation, from the fertilizers production to energy consumption for all cultivation techniques such as tillage. The data were calculated using Cool farm tool software. In order for the data to be representative and verifiable, the average of all the fields is referred in the study. The analysis of the emissions concerned all the fields where cotton is grown in a remarkable area. The total CO2e emissions coming from an average value of 117.32 ha are 43.11 k kg. The main source of emissions are the fuels used for all processes in the field such as harvesting, cultivator, irrigation, etc. Many factors significantly affected the GHG emissions from cotton field in Greece. Although water supply and N fertilizer are the main source for emissions only from soil, there are many factors to exanimated in order to minimize adverse effects of climate change.
虽然棉花种植被认为是希腊的主要经济作物，但种植方法及其环境友好水平是最近研究的重点。研究了棉花种植过程中温室气体的主要来源。到目前为止，农作物种植只会刺激土壤中的温室气体(GHG)排放。因此，发现主要来源是农业实践，如灌溉和施肥。必须对希腊境内棉花种植中的温室气体排放源进行估计。本研究考虑了与棉花种植有关的所有因素，从肥料生产到耕作等所有种植技术的能源消耗。数据采用Cool农具软件计算。为了使数据具有代表性和可验证性，在研究中引用各领域的平均值。对排放的分析涉及在一个显著区域种植棉花的所有田地。平均117.32公顷产生的总二氧化碳排放量为43.11 k kg。排放的主要来源是用于田间所有过程的燃料，如收割、耕种、灌溉等。影响希腊棉田温室气体排放的因素很多。虽然供水和氮肥只是土壤排放的主要来源，但为了尽量减少气候变化的不利影响，还有许多因素需要检查。

Tuta absoluta (Meyerick) is a serious pest of tomato crop with larvae causing even 100% loss, if not effectively controlled. Native from South America, currently, it can be found throughout Europe, Africa and parts of Asia. In Romania, it was reported for first time in 2009 (Leaotă, 2009). In this study, 12 concentrations of Metarhizium anisopliae and Lecanicillium lecanii were prepared and tested on T. absoluta larvae to study the impact of entomopathogenic fungi on larvae mortality, under laboratory conditions. The results showed that only four experiments had a mortality rate of over 50% on T. absoluta larvae. The higher concentration had the highest mortality rate. Research shows that microorganisms are effective, but at very high concentrations, leading to a higher cost of production. In these conditions, we could recommend either to increase the colony forming units in the commercial products, or to enrich the crop area with beneficial microfauna before establishing the crop. The present study might be useful in developing future integrated management strategies for tomato leaf miner.

Phaseolus vulgaris is one of the most important vegetables with high nutritional value consisting in proteins, iron, magnesium, folic acid and complex carbohydrates. The aim of this study was to obtained a dwarf french bean genotype with the following characteristics: yield and quality potential, earliness and extreme environmental conditions. The variety was obtained by repeated individual selection and now is submitted to the conservative selection program. For all agro-morphological characters, descriptive statistics were calculated. The pods of Anisia beans are yellow and have a simultaneous maturation, easing the harvesting process. The average weight of a pod at consumption maturity was 4.23 g. The yield potential of fresh pods varies between 18-20 t/ha. From our studies, Anisia cultivar is suitable for cultivation both organically and conventionally. The research has been completed with obtaining of a new variety of dwarf french bean that has been registered in the Official Catalogue of Romanian Crop Plants under the name ‘Anisia’. The variety has a distinct phenotypic expressiveness with a high yield and quality potential.

The variety was obtained by repeated individual selection and now is submitted to the conservative selection program. For all agro-morphological characters, descriptive statistics were calculated. The pods of Anisia beans are yellow and have a simultaneous maturation, easing the harvesting process. The average weight of a pod at consumption maturity was 4.23 g. The yield potential of fresh pods varies between 18-20 t/ha. From our studies, Anisia cultivar is suitable for cultivation both organically and conventionally. The research has been completed with obtaining of a new variety of dwarf french bean that has been registered in the Official Catalogue of Romanian Crop Plants under the name ‘Anisia’. The variety has a distinct phenotypic expressiveness with a high yield and quality potential.","PeriodicalId":9406,"journal":{"name":"Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90628229","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}

Even though Delta-9-tetrahydrocannabinol (THC) is a psychoactive substance, studies indicate that it has therapeutic properties. Moreover, the modification in Greece legislation regarding the legalization of cannabis has resulted in new business opportunities for medical-cannabis related companies. This study aimed to evaluate whether different greenhouse cover materials affect THC yield and propose a business plan for any potential medical-cannabis related company in Greece. A greenhouse experiment was conducted in order to evaluate the effect of different plastic cover films in greenhouses for the cultivation of Cannabis sativa. Furthermore, the economic viability of a potential medical-cannabis related business in Greece was evaluated based upon a financial analysis. Yields were increased in greenhouses with double plastic cover materials (compared to the control). According to the results of our comparative economic analysis the production of medical cannabis in greenhouses constructed with double layered cover materials would significantly increase profits. Finally, greenhouse medical-cannabis production is much promising in Greece. Nevertheless, the use of appropriate greenhouse cover materials should be considered as they affect THC yield and therefore, the profit of the company.
