Item type:Publication, INFLUENCE OF FOLIAR FERTILIZING ON YIELD AND QUALITY OF THE TABLE GRAPE cvs. CARDINAL AND AFUS ALI(Ss. Cyril and Methodius University, Faculty of Agricultural Sciences and Food, Skopje, 2016)Poposka, HristinaDuring three consecutive years (2012-2014) an experiment has been conducted with an aim to determine the influence of the foliar fertilization on yield and quality of table grapes, cvs. Cardinal and Afus ali. The experimental site has been established in Tikvesko Vinogorje, at vineyards of AD ,,Goce Delcev,, location’s Trstenik, Kavadarci. The experiment has been conducted according the method of random block system with seven variants and three repetitions. The foliar fertilizers with different nutrient contents were applied in concentration of 0.5 %, four times during the growing period, at the stages: before and after blooming, buckshot berries and verasion. The following characteristics were investigated: content of macro and micro nutrients in leafs and shoots, yield, mechanical analyse of grape grains and chemical properties of must. On the base of the results gained, we can bring the following conclusion: foliar fertilization with a different content of macro and micro nutrients, aplicated in the same concentration and growing stages, showed biological justification in terms of increasing the content of macro and micro elements in the leaves and shoots, yield and the quality of the grape cardinal and afus ali. In both studied varieties the highest average yields has been achieved in variant 4 (Polyfeed GG 18-9-27 + 2MgO + ME). With the cultivar cardinal, the average yield is 5,23 kg/vine and 17,01 t/ha, which is significantly higher than control variant with increasing index of 25 %. The highest average yields with variety afus ali were 5,23 kg/vine and 20,66 t/ha, with a statistically significant difference from the control variant, on the level of probability P≤0,05 and P≤0,01, with increasing of 28 %. Foliar application of this fertilizer on both varieties leaded to the highest content of macro and microelements in the leaves and shoots, best grapes quality and the highest sugar content in the must. - 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, 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. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Microphenophases on some junebearing strawberry varieties in region of Skopje(Bulgarian Journal of Agricultural Science, 2013)Ana Selamovska, S. Kratovalieva, S. Petrovic, M. DimitrijevicThis paper gives an overview of the results from the microphenophases on junebearing strawberry varieties: Pocahontas, Evita, Marmolade, Belrubi and Elsanta in Skopje region, Republic of Macedonia. The beginning of the flower bud differentiation among the studied strawberry varieties is, on average, during the first half of August when the day lasts for 13.5-14 hours. The calyx is formed the second half of September, stamens during the first half of October, and the pistils during the second half of October. Archesporial tissue and meiosis are formed in November. The microspores are formed in December. Pocahontas variety has earliest flower bud initiation (FBI), followed by Evita, Marmolade and Belrubi. Elsanta variety has the latest FBI. The higher temperatures and a photoperiod (duration of sunshine)have positive influence on early FBI. - Some of the metrics are blocked by yourconsent settings
