Results of the research showed that fluted pumpkin stands with the longest vines of 4.72 and 5.89 cm; highest number of leaves of 48.77 and 44.29 as well as highest germination percentage of 35.25 and 35.00% in 2019 and 2020 cropping seasons were recorded by seeds located within the distal position of the pod. Similarly, days to 50% flowering of 75.50% and 76.00% in both cropping seasons revealed that seeds within the proximal position produced stands that gave early flowers over distal and middle positions which recorded late flowering. From the results therefore, seeds within the distal positions of fluted pumpkin pod gave stands with improved growth indices and are therefore recommended for the cultivation of fluted pumpkin (Telfairia occidentalis Hook.

Management of trees has a critical contribution to soil improvements. People's use of shelterbelts is varying across agroecology zones of Ethiopia. Some nations use it as their cultural expression, while the others use it as area demarcation (farming and home). In shelterbelt agroforestry practice, Millettia ferruginea, Sesbania sesban and Acacia abyssinica legumes tree species were deliberately planted for soil management across agro-ecologies. Considering the population and the farm size of farmers in Ethiopia, most farmers' knowledge of shelterbelts for soil management is scantly documented. This is due to a low level of awareness and expert consultancy. Therefore, this paper reviews the soil management roles and possible threats, opportunities, and challenges of shelterbelts. This review paper was developed through using related published papers. Scientists reported that areas covered by well-managed shelterbelts had good soil physical, biological, and chemical properties. The soil quality and fertility of the area further improved through good soil microbial activities. The tree crop compatibility, climatic factors, land use policy, and scarcity of land were among the possible threat and challenges to shelterbelts establishment. Generally, good tree and shrub management skills result in a high level of land productivity. Therefore, further development planners should focus on the extensive demonstration of shelterbelt practices as well as training and monitoring of farmers on such issues for their livelihood improvements.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136007609","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}

Its exceptional characteristics such as drought tolerance, high adaptability to extreme conditions, disease resistance, and low cultivation inputs, make it particularly suitable for cultivation by resource-poor farmers. However, the potential use of grass pea is limited due to the presence of anti-nutritional factors, including protease inhibitors, especially trypsin inhibitor. This study aimed to develop a rapid and reliable method for measuring TI activity in seeds of grass pea and to investigate the influence of genotype and environment on trypsin inhibitor (TI) activity in seeds of grass pea. A set of 25 grass pea accessions from seven European countries was cultivated in Slovenia at the Agricultural Institute of Slovenia, and a set of 12 grass pea accessions from the Serbian gene bank was grown in Serbia at the Institute of Field and Vegetable Crops. The TI activity varied considerably among the grass pea accessions studied, with values ranging from 26.7 to 90.3 TUI/mg. To further evaluate the effects of environmental conditions on TI activity, eight grass pea accessions originating from Serbia were grown in both Slovenia and Serbia. The TI activity of the accessions grown in Slovenia ranged from 26.7 to 81.0 TUI/mg, while the activity of the accessions grown in Serbia ranged from 40.3 to 57.0 TUI/mg. The correlation of TI activity between grass pea accessions grown in Slovenia and those grown in Serbia was 0.39, with genotype diversity being the largest contributor (55.9%). This study provides a valuable insight into the variability of TI activity in grass pea and shows the possible influence of environmental conditions on this trait. However, since the data are only from a one-year field trial, further studies are needed to fully evaluate the influence of different environmental factors on TI activity.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136007595","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}

Focusing on the importance of tomato in human nutrition and the problem of narrowed genetic variability, the aim of the study was to assess morphological and chemical diversity in IFVCNS germplasm collection. Twenty genotypes were analysed for the morphological and chemical fruit traits: average mass (g), length (cm), diameter (cm), pericarp thickness (mm), locules number, moisture content (%), total soluble solids (°Brix), ash content (%), total acidity (%) and pH value. Selected plant material for analysis included: landraces, traditional varieties, breeding lines and commercial varieties. Differences among tomato genotypes in all fruit traits were determined. Fruit mass and locules number had the highest coefficient of variation. The least differences between genotypes were observed in the fruit moisture content. Four principal components accounted for 90.6% of total variance or 36.5%, 24.2%, 19.8% and 10.1%, respectively. Along the axis of the first main component, genotypes were classified into three groups. The first component was defined by fruit length, diameter and mass. The second component was correlated with pericarp thickness and locules number, and the third with moisture content, ash content and total soluble solids. Based on the cluster analysis, genotypes were classified into three groups which were in agreement with the PCA groups. Hybridization between genotypes from different groups was proposed in order to create new hybrids and varieties and to increase tomato germplasm diversity. By crossing those genotypes, improved recombinations in morphological and chemical traits can be expected.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71045690","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}

Meloidogyne arenaria is present in regions with continental climate in glasshouses attacking a large number of host-plants. In October 2018, potato crop var. Balathon Rose with galls on 70% of all tubers was noticed during quarantine nematode species Meloidogyne chitwoodi and M. fallax survey in the locality Horgoš, municipality of Kanjiža, Vojvodina Province. Symptoms of stunted and wilted plants were detected as well. Females were used for morphological and molecular identification. Morphological identification of species based on females' perineal patterns indicated the sample as M. arenaria. Species identification was confirmed by molecular analyses using group-specific primers in the rDNA region and species-specific SCAR primers for M. arenaria species identification. To our knowledge, this is the first record of highly damaged potato crop caused by M. arenaria in the field in Serbia. The severity of the damage M. arenaria can cause to potato in the open field has not been observed in the part of Balkan peninsula with continental climate before. This tropical Meloidogyne species may become an emerging phytosanitary problem within Europe in the future due global warming and climate change.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71045817","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}

Therefore, certified hybrid seeds of maize (Oba super II), were exposed to three different doses of X-ray radiation: 3 MGy, 6 MGy, 9 MGy and a control, no exposure (0 MGy) to assess the effect of irradiation on growth performance, grain yield and nutritional status of maize. The field research was conducted in 2016 cropping season at Michael Okpara University of Agriculture, Umudike (latitude 05º 29'N; longitude 07º 33'E; altitude 122 masl), southeast Nigeria. The experiment was laid down in a randomized complete block design with three replications. The results indicated that X-ray irradiation significantly affected growth, yield and nutritional status of maize. The application of 6 MGy of X-ray dose gave the longest cob, highest 100-seed weight and grain yield (4,973.00 kg ha-1 ) as well as nutritional values of the crop such as b-carotene, vitamin C, protein and phosphorus relative to the other treatments suggesting a possible genetic synergy from the dosage level. Correlation showed that above ground dry matter, crop growth rate and absolute growth rate had positive and significant (P≤0.05) relationships with grain yield. The mean sequence of grain yield obtained from maize due to X-ray bombardment of the seeds before planting was in the order: 6 MGy X-ray irradiation>9 MGy X-ray irradiation>3 MGy X-ray irradiation>0 MGy X-ray irradiation.

The genetic diversity in spring camelina proved to be limited, so the identification and characterization of genetic variations in germplasm originating from different sources is considered very useful for development of efficient breeding programmes. The aim of the study was to use SSR markers in order to investigate genetic variation of twenty spring camelina accessions of different origin and estimate their genetic relatedness. Forty-five individual samples were taken from each accession and used for amplification of SSR markers P4C11, P6E4 and LIB19. Percentage of polymorphic loci, number of alleles, effective number of alleles, expected heterozygosity and Shannon's information index were used to estimate genetic variation. The accessions expressed different levels of genetic variation. The highest variability was found in cultivar Zavolzskij, breeding line CK2X-7, cultivar NS Zlatka and breeding line CK2X-9. The most uniform were cultivar Pernice, and population Maslomania. AMOVA (analysis of molecular variance) showed that 64% of the total genetic variation was attributed to variance within accessions and 36% to variance among them. IBased on genetic distance, accessions were divided in two clades, which both were further divided in two subclades. Genetic distance analysis indicated that there was overlapping in certain breeding programs and exchange of breeding germplasm.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71045474","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 study includes detailed analytical calculations of the realized value of production, cost calculation, and the realized financial results of carrot production on three farms of different sizes, as well as comparison of the obtained results. The cost calculation presented in the production calculations is based on the actual costs made during the technological process of carrot production and obtained from the producers. The economic categories were included and calculated for carrot production per hectare at all three farms. Production calculations provide producers with an insight into the costs of production, giving them the opportunity to better manage them. The calculations confirmed that each of the mentioned three farms had a specific production technology. The amount of costs in the surveyed farms was different, while the value of production and the achieved volume of production were at approximately the same level. Land consolidation and farm expansion would result in increased efficiency of agricultural production on smaller farms with a larger number of plots. Profits from carrot production can be increased by association of agricultural producers, for the purpose of a more favourable supply of inputs, more efficient product distribution with joint marketing, higher share of machinery as opposed to using manual labour, as well as careful monitoring of innovations introduced in the production process. All three farms achieved a positive financial result, which indicates that carrot production is profitable on both smaller and larger areas.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71045758","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 order to identify action of genes for grain yield plant-1 and its correlation with main yield components, incomplete diallel crossing was applied. The field trial was conducted at the experimental field of the Agricultural Advisory Service in southeastern Europe, during season 2012-2013. Mean values of F1 generation showed that crosses Apache × Prima had the highest value of grain yield plant-1 and Jackson × Balkan had the lowest. Common type of inheritance for grain yield plant-1 was over dominance. The ANOVA revealed that this trait was controlled by additive and non-additive effects. The best general combiner for grain yield plant-1 was Apache, and two crosses (Dragana × Jackson; Balaton × Nevesinjka) showed significant SCA effects. Components of genetic variance showed that dominant was more important than additive component, and the total number of dominant genes were in excess over the number of recessive genes in all parents. Furthermore, moderately low value of narrow sense heritability (h2=31.96%) was observed for grain yield plant-1 . Parent Sana contained maximum dominant genes, whereas parent Jackson had maximum recessive genes. Grain yield plant-1 was significantly correlated with tillers numbers plant-1 at genotypic level (rg=0.494).
