In this paper was evaluated the effectiveness of three cover crops on soil chemical properties and weed suppression. The experiments were performed on cambic chernozem soil from NARDI Fundulea Romania in two contrasting years regarding the amount of precipitation. Three cover crops were studied. The cover crop consisting of peas + triticale has increased more soil carbon content and infestation with weeds were lower as compared with cover crop consisting of peas or triticale. The differences concerning carbon sequestration, soil organic carbon, carbon to nitrogen ratio, weed suppression were influenced also by level of precipitations from experimental site. Cover crops were slow to impact C/N ratio of soil. In contrast, the floristic composition, and the degree of weed infestation were very significantly influenced by the composition of the cover crops. The use of cover crop mixtures offered an additional benefit to weed suppression that of individual cover crops.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71120114","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On average for the study period, the grain yield from the organic production system was by 35% lower than that achieved from the conventional production system. Hectolitre weight was also, affected by production system showing in the organic system values by 2% lower than in the conventional system. The cultivar Miranda was more stable than the other studied cultivars in both conventional and organic production system.

Crantz), has gained considerable attention in Europe as a potential oil seed feedstock for biofuels and bioproducts, although as cultivated surfaces it remains a marginal crop. As well in Romania progress has been made towards camelina’s yield potential but this under organic agriculture conditions has not been studied enough. Given this increased interest in camelina, six genotypes were compared to characterize camelina’s production potential in organic farming. Field experiments were conducted out in a randomized complete block design (RCBD) with four replications, six genotypes in three growing seasons (2016-2019). Plant population, frequency (F%) of downy mildew attack, weeds infestation and yield were evaluated. The higher amount of spring rainfall (in 2017 and 2019) and cooler temperatures favoured a significant downy mildew plant infection, with some variations among genotypes. GP 202 proved to be most sensitive to downy mildew attack followed by Lena. The most resistant genotype was Calena, which recorded, for the three different years, the lowest degree of attack. In weeds suppression the variation due to year was higher than that due to the genotype and interactions of the factors. Results identify, in relation to climatic conditions, the most suitable genotypes for the tested environment, in terms of resistance to downy mildew and weed infestation. Calena, Camelia and Lindo genotypes were more less affected by downy mildew, weed infestation was less and the yield was higher as compared to the other genotypes studied.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71120538","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results showed that the lowest percentage of normal seedlings, seedling emergence immediately and one year after seed pelleting and rate of germination coefficient immediately after pelleting, was in case of pelleted seeds with 2 mm diameter. Non-pelleted seeds had the highest germination and seedling emergence did not decrease significantly one year after pelleting. The results of this study showed that all seed disinfection treatments improved germination and seedling emergence percentage in floating seedbed trays and transferable seedlings, also seedlings infected with collar rot, sciaridae fly and aphids were reduced.

Cereal fields and orchards are often in close vicinity to sunflower fields, and herbicide drift from these areas can adversely affect sunflower. Fields experiments were conducted at Edirne and Ankara, Turkey, in 2018 and 2019 to quantify the sunflower (IMI - resistant) response to various simulated drift rates of glyphosate, glufosinate, and indaziflam. Herbicides were applied to sunflower at 12.5, 6.25, 3.125, and 1% of recommended rates. Crop injury was visually evaluated at 7, 14, and 28 d after treatment (DAT), and plant responses to herbicides were assessed at harvest. Sunflower was injured by all rates of glyphosate applied, with 15 to 100% (in Edirne) and 9 to 84% (Ankara) injury at 28 DAT. Glufosinate - related injury was 5 to 58% in Edirne and 7 to 43% in Ankara at 7 DAT, and decreased with time. In contrast, indaziflam caused no significant crop injury or yield losses. The recommended rates of 6.25% and 12.5 of glyphosate killed all sunflower plants in 2019, while in 2018 the yield loss was 100% only at recommended rate of 12.5% glyphosate. Lower rates of glyphosate reduced yield by 2 to 87% in 2018 and 18 to 62% in 2019. On the other hand, the two highest rates of glufosinate resulted in a yield reduction of 9 and 6% in 2018, respectively, but not in 2019. Injury at early stages after exposure is a good indicator of the impact of glyphosate drift on sunflower yield.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71120939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this regard, CBF systems have the most important role in tolerating cold stress in plants. It is very important to study and compare the sequence of CBF gene and determine the phylogenetic and evolutionary relationships of this gene in different plants using bioinformatics tools. In this study, by examining the amino acid sequence of protein expressed from CBF gene in durum wheat (tetraploid), from Plantcare, NCBI and EXPASY databases and also to investigate the relationships of this gene in forty different plant species, their homology from in terms of protein similarity with MEGA5, UPGMA and Bioedit software was determined. Bioinformatics analysis showed that the nucleotide length of this gene among the forty plants studied above varied from 453 nucleotides for pine to 759 nucleotides for rice. It also showed that the length of this gene in hexaploid wheat plant contains 214 amino acids. The results of analysis of variance showed high diversity between plants. The evolutionary matrix was calculated based on Poisson correlation and showed that there is the highest distance (4.324) and the lowest distance (0.007) between the protein sequences of CBF gene in plants. Based on the results of cluster analysis by UPGMA method, the protein sequence of this gene was divided into three groups. AP2 and ABRE regions were observed in the initial sequence of CBF gene and also the presence of CAAT box in most plants. The existence of genetic diversity of CBF gene in different plants confirms that the differences in gene expression and differences in protein form are due to environmental effects, which in the long run have epigenetic effects and genetic modification of that gene in that plant.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"1 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71119970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The LARS-WG6 model was employed to simulate the meteorological data obtained from Rasht Meteorological Station under the RCP8.5 and RCP4.5 scenarios for the 2020-2050 and 2060-2090 periods. The simulated values were assessed based on the measured values of total biomass and grain yields using the coefficient of determination (R2 ), the relative error parameters, and the normalized root mean square error (RMSEn). The calculated values of RMSEn varied from 7 to 4% for grain yield and from 3 to 7% for biomass yield at the calibration and validation stages, respectively. The results suggested that the AquaCrop model had suitable accuracy in predicting biomass and grain yields. The findings indicate that climate change decreased mean rice grain yield by 17 to 23% under the RCP4.5 scenario and by 18 to 23% under the RCP8.5 scenario for 2050 and 2090, respectively, in non-flooded irrigation management. The lowest simulated mean biomass and grain yields were obtained under irrigation at 11-day intervals in scenario RCP8.5 for the second future period (2060-2090). In general, non-flooded irrigation management had negative effects on rice grain yield under climate change. Moreover, the mean rice growing period under both RCP8.5 and RCP4.5 scenarios declined by 2090. These findings can be used for a broad spectrum of users such as farmers, agricultural engineers, and project managers in practical policymaking and making correct decisions compatible with the region in order to increase rice grain yield productivity under future climate conditions in northern Iran.","PeriodicalId":49589,"journal":{"name":"Romanian Agricultural Research","volume":"26 4 1","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71120557","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
