As organic agriculture represents one of the most sustainable ways of agricultural land use, the key purpose of this research was to improve confectionary sunflower production in organic agriculture. The trial compared seed yield per plant of conventional confectionary sunflower hybrids in organic vs conventional production. Subsequently, 1000 seed weight, seed yield per plant and kernel ratio of confectionary hybrids treated with the following fertilizers used in organic production: fertilizer of animal origin (G), fertilizer based on amino acids and nitrogen (T) and microbiological fertilizer (N) were compared with untreated control (C). Fertilizers enhanced yield of sunflower compared to untreated control; the highest yield was recorded in combined of G+N and G+T, all in organic agriculture system. NS Gricko had the lowest seed yield per plant compared to the other hybrids that significantly increased when treated with G+N fertilizers; same results were obtained in treatments of NS Slatki, and NS Leviathan. Preliminary results of the study indicated that application of organic fertilizers can have a positive effect on yield of sunflower in organic production conditions, which indicates that further research is necessary.

Estimation of the level of durum wheat germplasm genetic diversity is important for its classification and efficient use in breeding programmes. The aim of this study was to assess genetic diversity of durum wheat genotypes developed at the Institute of Field and Vegetable Crops in Novi Sad, Serbia, with 26 morphological characteristics based on the International Union for Protection of New Varieties of Plants guidelines. The Shannon diversity index was used as an indicator of morphological diversity and it ranged from 0.283 for glaucosity of lower side of the flag leaf blade and density of hairiness of uppermost node of the culm, to 0.950 for the ear colour, with the mean value of 0.616, indicating a medium to high level of morphological diversity. On average, the diversity was higher for traits relating to generative organs than for those associated with vegetative plant organs. The 21 morphological characteristics were sufficient to distinguish unique profiles of all durum wheat genotypes. The estimation of varietal diversity and identification of morphological characteristics with the highest discriminative power were done by multiple correspondence analysis. The traits that contributed the most to the distinction of genotypes were the ear colouration, length of beak of the lower glume, lower glume shape, ear length of awns at tip relative to ear length and colour of awns. Morphological characterization using the traits with the highest discriminative power could be a useful complementary method for durum wheat germplasm classification and diversity analysis.

Dill (Anethum graveolens L.) is a one-year herbaceous, spicy plant, which has aromatic smell and taste. One of its important ingredients is essential oil. The experiment showing the effect of irrigation on essential oil and biomass yield of dill was conducted in rainy 2016 and dry 2017 in two variants: control (without irrigation) and variant with irrigation. Favourable water balance of the soil was provided by applying drop-by-drop irrigation method. The average yield of fresh biomass was 8,252 kg ha-1 (10,194 kg ha-1 under irrigation and 6,310 kg ha-1 in control). Under irrigation, the yield of biomass was higher than the control variant by 78.59% in 2017 and 47.41% in 2016. Under irrigation, essential oil content and yield were higher than the control by 10.73% and 95.97% in 2017, respectively, and 3.93% and 54.06% in 2016, respectively.

In 2018, a total of 58 mustard samples from two different localities in Serbia (Rimski Sancevi and Senta) were collected and tested for the presence of Turnip yellow virus (TuYV), Cauliflower mosaic virus (CaMV) and Turnip mosaic virus (TuMV) by DAS-ELTSA. TuYV was serologically detected in 42 tested samples while all collected samples were negative for CaMV and TuMV. By using aphid transmission tests, five test plants were inoculated with two ELTSApositive TuYV samples of naturally infected mustard plants. Virus species identification was performed by amplification of a 780 bp fragment in all tested samples using the specific primers TuYVorf0F/TuYVorf0R. The RTPCR products from two isolates 88Sal (MK144816) and 98Bni (MK144817) were sequenced and compared with the GenBank sequences of TuYV. Serbian isolates showed the highest identity with Poland TuYV isolate (EU022489). Phylogenetic analysis showed that TuYV isolates from Serbia were clustered with other TuYV sequences retrieved from the GenBank.

Conventional mutation breeding techniques have often been used to improve yield, disease and pest resistance in crop plants. In the present attempt, two well-known mutagenic agents ethyl methane sulphonate and EMS were employed in order to induce genetic variability variety of chick pea Co -4 obtained from Tamil Nadu Agricultural University. The seeds were treated with different concentrations of EMS (10-50 mM) and Gamma rays (20-60 kR). A total of 369 mutants which alter the height, leaf structure, colour of flower, seed, size of pod, duration of the plant were isolated and characterized. Among them, five true breeding mutants namely Early flowering mutant (EFM), Bold pod mutant (BPM), Bold seed mutant BSM), High yielding mutant (HYM) and High protein content mutant (HPC), which directly influenced the economic value of the crop were selected for further study. The results revealed a significant positive increase in the qualitative traits among the mutant lines. The RAPD profiling of isolated mutants revealed a total of 129 bands, among them 92 were polymorphic with an average of 70.99 percentage of polymorphism. Apart from 28 bands, all the bands seemed to be mutation. The presence of new bands and absence of existing bands might be the reason for quality improvement of chickpea. The RAPD is considered as an excellent marker to differentiate mutants from their parents, to assess genetic variation and phylogenetic relationship.

The most critical aspect of plant survival and reproduction is seed germination. Considering the specificity of the Cannabis sativa production, obtaining high-quality hemp seed is not an easy task. Germination testing is often the most reliable way of assessing viability, but the selection of appropriate methods is complex. This study aimed to evaluate the effect of different conditions (i.e. various methods of germination testing) on the successful process of hemp seed germination, achieving maximum germination potential. Our results showed that C. sativa seeds germinated well in different methods, such as between filter papers, top of filter papers and sand, but there were significant differences between the applied methods. This means that the hemp seeds may have different requirements for germination than conditions covered by the Rules recommended methods. Further, the results show that hemp seed may have certain residual dormancy that needs to be investigated in detail.

Wild perennial pea Vavilovia formosa is a relic and an endangered species of the upper alpine flora of Armenia, specialized to scree habitats. The populations of V. formosa in Armenia, as well as in other sites of the world, are in danger of extinction and need both in situ and ex situ complementary investigation and conservation. Present article contains information on V. formosa Aknasar mountain population studies. Data on natural conditions, flora composition, ecological and coenotic characteristic of the habitat and bio-ecological features of V. formosa are given. The present state of Vavilovia population of mountain Aknasar is satisfactory. The activation of seed reproduction along with vegetative propagation is observed. One of the natural threats leading to the change and reduction of Vavilovia population was estimated to be the overgrowing of mobile scree habitats with turf-forming grasses, which creates conditions for the mountain-meadow vegetation development. V. formosa ex situ conservation strategy is one of the possible ways of its adaptive capacity estimation to environment changes as well as for its saving and using in basic and applied researches. An introductory experiment on the cultivation of Vavilovia in the Yerevan and Sevan Botanical Gardens has started, and some data on bio-morphological and eco-physiological peculiarities under ex situ conditions were obtained.

Alfalfa is an autotetraploid, perennial forage crop adapted to different environments and management systems. Trial with 12 alfalfa populations was established in spring of 2014. The research involved 9 commercial alfalfa varieties from IFVCNS, Serbia, and included 3 experimental populations in the final phase of breeding program. The main objectives of this paper were to examine the impact of variety selection on alfalfa yield and plant height in intensive cutting management in order to define harvesting strategies (using 6 and 5 cuts per season), with main goal to maximize profit on alfalfa farms in Serbia and Southeast Europe. Our study clearly demonstrates that there is genetic potential in some Serbian varieties (NS Sila, Nera, NS Jelena, and Banat VS) for use in intensive cutting systems with 6 cuts per year that can meet farmers' needs in conventional or organic type of alfalfa hay production.This research represents an initial guideline for the alfalfa variety selection in intensive cutting management systems in Serbia and Southeast Europe.

This study assesses the potential of antibiotics-producing Pseudomonas chlororaphis strains to increase potato yield and to inhibit the mycelial growth of phytopathogenic fungi Fusarium oxysporum (Fo) isolated from potato. P. chlororaphis subsp. aurantiaca strain Q16 (PchlQ16) caused the highest growth inhibition (67.07%) of FoA2 isolate in vitro. In field trials the effect of PchlQ16 was measured as the number of stems, number and weight of tubers and a total potato yield of the Rudolph potato variety. Application of P. chlororaphis and the number of treatments exhibited a significant effect on the yield. Two treatments of PchlQ16 increased the total yield of tubers from 4.9% to 33.05%, while four treatments from 9.3% to 92.35%, compared to the control. Based on our field results we can recommend a frequent application of PchlQ16 (4 times) during potato growth season. The results of our in vitro experiment support these findings as the bacterial strain suppressed growth of F. oxysporum. In this investigation PchlQ16 was confirmed as an effective growth promoting agent in potato production and can be highly effective in prevention of F. oxysporum infection.

In field trials the effect of PchlQ16 was measured as the number of stems, number and weight of tubers and a total potato yield of the Rudolph potato variety. Application of P. chlororaphis and the number of treatments exhibited a significant effect on the yield. Two treatments of PchlQ16 increased the total yield of tubers from 4.9% to 33.05%, while four treatments from 9.3% to 92.35%, compared to the control. Based on our field results we can recommend a frequent application of PchlQ16 (4 times) during potato growth season. The results of our in vitro experiment support these findings as the bacterial strain suppressed growth of F. oxysporum. In this investigation PchlQ16 was confirmed as an effective growth promoting agent in potato production and can be highly effective in prevention of F. oxysporum infection.","PeriodicalId":20996,"journal":{"name":"Ratarstvo i Povrtarstvo","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71044068","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}
