Item type:Publication, TIMING OF INOCULATION WITH SELECTED WINE BACTERIA ON THE KINETICS OF MALOLACTIC FERMENTATION AND SENSORY PROPERTIES OF VRANEC WINE FROM TIKVESH WINE REGION(Faculty of Agricultural Sciences and Food, 2019) ;Goran Milanov ;Dushko NedekovskiMilena Taseski-GjorgjijevskiThe aim of this investigation is to determine the influence of timing of inoculation of four different lactic bacterias by co inoculation during the fermentation and post-fermentation of Vranec variety, to obtain more balanced wines with refined aromas. VP 41, ML Prime, O-Mega and PN4 are the types of commercial available lactic bacterias produced by Lallemand producer, used in malolactic fermentation (MLF) of wine Vranec. The kinetic of transformation of malic into lactic acid was measured. Also, chemical composition of wine (alcohol strength, specific gravity, total extract, total acids, volatile acids, pH, free and total SO2) wasperformed. The sensory descriptive analysis was performed. Seven wine experts were involved for the descriptive evaluation of the investigated wines. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, POTENTIAL AND POSSIBILITIES OF REBO – NEW GRAPEVINE VARIETY (Vitis vinifera L.) IN GROWING CONDITIONS IN REPUBLIC OF NORTH MACEDONIA(Goce Delcev University of Štip, 2019) ;Dushko Nedelkovski1 ;Klime Beleski ;Goran Milanov1 ;Venelin RoychevVioleta DimovskaRebo (Rigotti 107-3) is a vine variety that originates from Trentino, North Italy. It was selected by the researcher Rebo Rigotti by crossing the varieties Merlot x Terlodego at the agriculture and forest experimental station in S. Michele all’ Adige. According to the literature the idea of the breeder was to produce new variety that would be similar to Merlot but more resistant to cold climate conditions. Our idea to plant Rebo in Macedonia was to grow this variety on sites with higher altitude locations that are difficult for growing Merlot. The vineyard for this study is located in the north part of Macedonia on the mountain German near the town of Kriva Palanka, area typical for growing frost resistant varieties. In this research paper we analyzed the mechanical structure of the grape cluster and berries, the quantity of sugar and titratable acids in the grapes. In the wine we analyzed the quantity of total phenols, total anthocyanins, wine colour (CI;H), total flavan-3-ols and standard chemical analysis of the wine - Some of the metrics are blocked by yourconsent settings
Item type:Publication, YIELD AND MINERAL COMPOSITION OF GRAPEVINE AS AFFECTED BY MAGNESIUM AND IRON FOLIAR NUTRITION(Goce Delcev University of Štip, 2019) ;Hristina Poposka ;Dusko MukaetovDusko NedelkovskiThe aim of this study was to evaluate foliar fertilizers (Magni mag helat and Magni fer helat) effects on yield, quality parameters and nutrient contents of the leaves of vine cultivar Cardinal in comparison to control variant (without foliar fertilizer). Field trials has been organised according the method of random block system with three variants (including control variant I) in three repetitions. Foliar fertilizers were applied in concentration of 0.5 %, four times during the vegetation period (before and after blooming, buckshot berries and version). Results for 3 years indicated that Mg and Fe fertilizers application affected the yield of grape and its quality. Fertilized Variant III had higher average yield with 14.87 t/ha. Foliar fertilizing with Fe has significant effect on increasing of: total cluster weight, berries weight per cluster and percentage of berries. Treated variants had a lower weight of skin and seeds, compared with the control. A substantial influence of foliar fertilizers on analysed element contents in leaves has been identified, also. The 3-years average content of macro and micro elements showed higher content of P (0.35 %), Ca (3.03 %), N (2.25 %), Mn (133.24 mg/kg) and Cu (18.18 mg/kg), at Variant II. Results of leaf tissue confirmed some antagonistic relations between analysed elements, like: Fe/P, Mg/K and Fe/Mn. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Примена на нов препарат врз база на зеолит кај растенијата и негово влијание врз намалување на загадувањето на околината(МАКЕДОНСКА АКАДЕМИЈА НА НАУКИТЕ И УМЕТНОСТИТЕ MACEDONIAN ACADEMY OF SCIENCES AND ARTS (RESEARCH CENTER FOR ENVIRONMENT AND MATERIALS), 2019-04)Биљана Коруноска, Владан ПешиќAbstract In the R. Macedonia still has good ecological conditions for the life of people, animals, and above all for the cultivation of healthy plants and for the production of healthy and unpolluted food. But pollution globally caused by industry and urbanization, increasingly have in our country. As a consequence, it is with us in the air, water, soil, etc. certain zones of pollution with harmful particles have been identified. Therefore, a large number of scientists in the R. Macedonia is seeking concrete solutions to reduce pollution, especially in urban areas. Especially critical regions are those, where there is intensive agricultural production (food production) in urban areas. In these environments there is a huge pollution due to the use of modern machinery (fuels) and the use of pesticides (poisonous chemicals) Hrenović, Ivanković and collaborators [1, 2]. In addition, in our work, we offer a concrete solution by applying a new preparation based on the zeolite mineral in two variants - Terra Foster and Terra Powder. Our studies have shown that these preparations can replace most of the harmful pesticides used for plant protection. Also, quality, healthy and unpolluted plants are obtained. And most importantly, when applying the zeolite, it has an absorbent character and acts as a "cleaner" of soil from certain heavy metals and acts on the soil pH correction, (comparisons were made according to Blake's geological analysis) [3]. These preparations are especially suitable for use in food production in urban areas. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, AGRICULTURE, ENERGY AND MATERIAL FOR SUSTAINABILITY IN THE EDUCATION PROCESS(JOURNAL OF ENVIRONMENTAL PROTECTION AND ECOLOGY, 2018)V. Pesic; N. Shaban; V. Weingerl; E. Kadhum; B. KorunoskaAbstract. It is widely understood that agricultural production is based on the exploitation of natural, primarily biological, chemical and physical resources. Thus, the soil (lithosphere) represents the physical source, i.e. the foundation for cultivation of cereals, field crops, fruit- and vine growing. Furthermore, it represents the chemical source supplying the crops with an adequate amount of both major and trace elements and other nutrients. Indirectly, it is also a source of the nutrients required in livestock production. The definition of an ecosystem and agriculture as its constituent part offers a better understanding of the importance of energy investments, consumption and production of energy in agriculture. The abiotic or non-living component part is made up of chemical and physical factors of the environment of the biotic component part (namely, climate, water, air and soil). Water presents the abiotic component part of a pond, whereas air, soil and sunlight present the abiotic factors in either a garden, a wheat-growing field or on a pasture. Producers, consumers and decomposers present the three biotic component parts of each ecosystem. In the case of energy flow through the ecosystem, the implementation of the First and the Second Law of Thermodynamics showed that more than 90% of the total energy captured by the producers, disappeared from the food chain each time it was converted and moved from one to another trophic level. The greatest amounts of energy in an ecosystem or food chain were found to be stored in the primary producers and had a declining trend with each trophic level that followed. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, THE INFLUENCE OF THE RUNNER ORDERING OF THE PLANTS ON THEIR QUALITY, ROOTING AND YIELD OF STRAWBERRIES(Zbornik Matice srpske za prirodne nauke /Proc. Nat. Sci, Matica Srpska Novi Sad,, 2010)Ana T. Selamovska, Olga V. NajdenovskaIn this work, we presented the influence of the runner ordering of the plants on their quality, percentage of root hair formation, and yield of two varieties of strawberries: Senga Sengana and Pocahontas depending on the time of planting. The runner ordering of plants and time of their planting have influence on the quality of plants, the percentage of root hair formation after the planting, and the yield. There has been established strong correlation among the diameter of the crown and the rooting when planted and the yield. Primary plants have higher quality, with bigger diameter of the crown, they take root better, and they have higher yield than secondary plants. Rosettes planted in August have higher yield than the ones planted later. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Effects of rosettes quality and ordering on yield potential in strawberry(ISHS Acta Horticulturae, 2009)Ana Selamovska, K. NikolicThe influence of the rosettes quality and ordering depending on planting period upon the yield potential, the yield and the fruit quality of strawberries was determined during the researches. The primary rosettes are of better quality, they have a bigger diameter of the root crown, form bigger yield potential and give a higher yield than secondary rosettes. The biggest differences between researched parameters are found the first year after planting. Significant differences between fruit mass of primary and secondary rosettes are not found. Primary and secondary rosettes that are planted in August form a bigger yield potential; they give a higher yield and form bigger fruits than the ones planted later. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Influence of some factors on microsporogenesis in strawberry(ISHS Acta Horticulturae, 2009)Ana Selamovska, S. Kratovalieva, G. PopsimonovaMixed first and second order flower buds of both mother and runner plants of the Fragaria x anannassa ‘Pocahontas’ and ‘Senga sengana’ cultivars were studied in dependence of the climate factors and the management of the plantation. The climate factors, the runner plants ordering and the plantation management determine the start of microsporogenesis in strawberry cultivars. Microsporogenesis of mother plants and of first rosettes starts 10-15 days earlier than in the secondary rosettes. Microsporogenesis of plants cultivated in an orchard on black foil starts 7-10 days earlier than of plants cultivated in an orchard without foil - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Comparative research on yield in some strawberry rosettes depending on planting time.(Institutul de Cercetare-Dezvoltare pentru Pomicultura Pitesti-Romania, 2008)Ana Selamovska, Boris Ristevski, Katerina NikolicThe influence of planting time and the quality of rosettes on yield in two strawberry cultivars: Senga sengana and Pocahontas was researched. We used three kind of rosettes: unrooted, produced from mother orchard mulched on black folio; rooted rosettes with developed root, produced from mother orchard on bare soil and rooted cuttings. The rosettes were planted in three occasions: 15.08, 15.09 and 15.10. According to the results, all kinds of rosettes planted first gave the highest yield, and this was found with high and significant statistical differences. The rosettes planted on the 15th of August gave 73-79% higher yield versus the later planted rosettes of the 15th of September and 15th of October. Rooted rosettes produced on mother orchard on bare soil gave 17% and 27% higher yield than rooted cuttings and unrooted rosettes. Statistically significant differences between cultivars with regard to the quality of the rosettes and the planting time were not found. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Interaction of environment conditions and genotypes on expression of genetic background in micro-phenophases of strawberry mixed flower bud.(GENETIKA, 2013)Ana Selamovska, S. Kratovalieva, K. NikolicThe aim of this research is differentiation of microphenophases of reproductive organs on two junebearing strawberry (Fragaria x anannassa) varieties senga sengana and pocahontas, depending on climate conditions, rosettes ordering and cultivate manner (orchard mulched on black foil and orchard on bare soil). The beginning of differentiation of flower buds is genetic characteristic depending on climate conditions (insulations, day length, higher the sum of rainfalls from the beginning of May until the end of July), order of rosettes and cultivate manner. The sum of effective temperatures over 10oC from 1st of May till the beginning of differentiation has no influence on beginning of flower buds differentiation. First morphological changes of the apical meristem were started in the first decade of August that has coincided with the day length of 14 hours and day insulations of 9.3 hours. Micro-phenophases were undergoing almost at the same time in both varieties, only the beginning at pocahontas was 2-3 days earlier. Primary rosettes differ 10-15 days earlier than secondary rosettes. Plants that grown on black foil had 7-10 days earlier flower bud differentiation compared to those grown on bare soil.
