Item type:Publication, Possible Replacement of Wheat Post Herbicides with Soil Herbicide Pendimethalin(University of Zagreb, Faculty of Agriculture, Zagreb, CROATIA, 2022-01-23)Arben MEHMETI Jeton RAMADANI Zvonko PACANOSKI Rozafa FETAHAJ Elez KRASNIQIThe experiment was conducted between 2016-17 to evaluate the efficacy of PRE emergence and POST herbicides for effective weed control in wheat crops and analyse if pendimethalin may replace usually spring post-applied herbicides. The applied PRE emergence herbicide was pendimethalin and POST herbicides were prosulfuron, amidosulfuron + iodosulfuronmethyl- natrium + mefenpyr-diethyl, pyroxsulam, amidosulfuron + iodosulfuron-methylnatrium + mefenpyr-diethyl + fenoxaprop-p-ethyl. The weed population consisted mainly of annual and some perennial weeds. Weediness comprised 31 plants m-2 in the control plots and 1.3-9.0 plants m-2 in the plots treated with herbicides. The highest numbers of individuals were recorded for Persicaria maculosa (8.0 plants m-2), Chenopodium album (7.3 plants m-2), Apera spica-venti (7.0 plants m-2) and Convolvulus arvensis (3.0 plants m-2). Most POST herbicides effectively reduced dominant weeds with the highest efficacy in plots treated with herbicide amidosulfuron + iodosulfuron-metil-natrium + mefenpir-dietil (95.9%). Furthermore, the efficacy of PRE herbicide pendimethalin with two doses was lower compared to POST herbicides, besides amidosulfuron + iodosulfuron-metil-natrium + mefenpir-dietil + fenoxaprop-p-ethyl. The treated plots with herbicides showed a statistically higher wheat yield compared to control plots. The PRE herbicide pendimethalin may replace POST herbicides, but this depends strongly on used dosage, climatic conditions and weeds that germinate in the spring. Wheat yields differed among PRE herbicide pendimethalin applications and POST herbicide, ranging between 5115 and 7003 kg ha-1. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Management Systems for Biannual Seed Crop of Italian Ryegrass (Lolium multiflorum Lam.) Grown at Various Nitrogen Fertilization: I. First-Production Year Characterized by Limited Crop Lodging and High Seed Shattering before Direct Combine-Harvesting(MDPI, Basel, Switzerland, 2022-02-26)Zlatko Sveˇcnjak, Dario Jareš, Ana Milanovi´c-Litre, Zvonko Pacanoski , Darko Uher and Dubravka Dujmovi´c PurgarLittle is known about the best management systems for seed production of Italian ryegrass. The main objective of this study was to determine the influence of management systems on the firstyear seed crop grown under various nitrogen fertilization (0, 60, 120 and 180 kg ha1). Management systems of single-purpose crops were with (SeedPGR-crop) and without (Seed-crop) plant growth regulator application. The dual-purpose crops incorporated early spring forage cut during stem elongation (EF-seed-crop) and late cut at the onset of heading (LF-seed-crop) followed by seed harvest. Compared to the single-purpose crops, the dual purpose-crops shattered much less seeds but still yielded less because their plants had lower number of visible nodes on stems, shorter ears, fewer spikelets per ear, fewer flowers per spikelet in various ear sections and lighter seeds. Despite similar lodging incidence, the SeedPGR-crop produced relatively small, but significantly larger seed yield than the Seed-crop because plants in the SeedPGR-crop had shorter stems with fewer vegetative tillers, and shattered seeds slightly less. Nitrogen fertilization consistently improved seed yields in all management systems regardless of associated increases in lodging and seed shedding. These yield increments were mainly associated with the increased number of early- and late-formed reproductive tillers, and partly due to improved number of florets per spikelet and slightly heavier seed in early formed reproductive ears. In spite of larger seed losses through shattering, the single-purpose crops largely out-yielded and had higher seed germination than the dual-purpose crops at all nitrogen fertilization rates, with maximized yields produced in the SeedPGR-crop. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, EFFECTIVENESS OF DIFFERENT ADJUVANTS ON EFFICACY OF STELLAR (TOPREMAZONE PLUS DICAMBA) APPLIED AT REDUCED RATES IN MAIZE (Zea mays L.)(Estonian Academic Agricultural Society, 2022-05-07)Zvonko Pacanoski, Alirami Saliji, Arben MehmetiField experiments were carried out in 2017 and 2018 on two individual farms that grew maize for grain, in Tetovo and Skopje locality, to determine the effectiveness of different adjuvants on the efficacy of Stellar applied at reduced rates. Herbicide treatment selectivity and influence on grain yield were estimated, as well. Both sites were naturally infested with a high population of Polygonum lapathifolium L., Chenopodium album L., Echinochloa crus-galli (L.) P. Beauv. and Sorghum halepense (L.) Pers. Overall efficacy of herbicides in control of weeds 28 DAT was ranged of 77% (Stellar + White oil applied at 0.125 + 0.2 L ha–1) to 98% (Stellar + Trend applied at 0.75 + 1.0 L ha–1) in Tetovo locality, and 64% (Stellar + White oil applied at 0.125 + 0.2 L ha–1) to 99% (Stellar + DASH applied at 0.75 + 2.0 L ha–1) in Skopje locality, respectively. In both localities, the efficacy of the full rate of Stellar (90 and 80%, respectively) was on the level of Stellar + White oil applied at 0.25 + 0.2 L ha–1 (90 and 78%, respectively). Herbicide efficacy 56 DAT was similar to the previous period of estimation. Efficacy of herbicide and herbicide plus adjuvants treatments in control of prevailing weeds 28 and 56 DAT ranged from 22–100% in Tetovo locality and 30–100% in Skopje locality, respectively. No visual maize injured was determined by any herbicide treatments in both localities for both years. Maize grain yields for each treatment in both localities generally reflected overall weed control. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, The impact of using combinations of N, S and B in oilseed rape - Brassica napus L. on quantitative properties of seed(ISAF, 2017-10)• Igor Iljovski, Romina Kabranova, Zoran Dimov, Vjekoslav Tanaskovikj, Ile Canev, Tatjana PrentovicAs a result of the use of the following elements - nitrogen (N), sulphur (S) and boron (B) - quantitative properties of two genotypes of oilseed rape - Brassica napus L., Zorica (variety) and Rohan (hybrid) were determined. The main purpose of the study was determination of the production mode, set in both genotypes of oilseed rape versus managing various nutrients. An experiment was set in the Skopje region, on total experimental area of 650 m2. For this purpose, the following combinations of fertilizers were used: N1 with 110 kg/ha nitrogen, N2 with 150 kg/ha nitrogen, S1 with 30 kg/ha sulphur, S2 with 70 kg/ha sulphur, B1 with 1.0 kg/ha boron, and B2 with 2.0 kg/ha boron (at spring time, foliar application) versus standard variant: N:P:K in the ratio 10:20:30 (N 50 kg/ha, 90 kg/ha P2O5 and 180 kg/ha K2O) used in autumn. During the experiment the following parameters were monitored: height of plants (cm), number of branches per plant, number of pods per plant, length of pod (cm), number of seeds in the silique, and seed yield (t/ha). From the combinations of nutrients and variations that have been set in terms of genotypes, the results of yield showed statistical significance at level of 0.05 from variants N2PK, N2PK+S2+B2 in variety Zorica and N1PK+S1+B1 in the hybrid Rohan. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Introduction of Mating Disruption Pheromones in apple orchards in Fyr of Macedonia(Integrated Protection of Fruit Crops IOBC-WPRS Bulletin, 2017)Stanislava Lazarevska, Mile Postolovski, Zoran Dimov , Sterja Naceski, Vesna Krsteska3, Shpend Shahini , Ivan PostolovskiDuring the 2014 and 2015 seasons, the control of codling moth (CM), Cydia pomonella (L.), in apple orchards in Prespa Region in Fyr of Macedonia was conducted with mating disruption pheromones. The apple is a dominant crop in this region and the codling moth pressure is constantly very high. Mating disruption technique in apple orchard was utilized for the first time with a single application of Isomate C TT dispensers per season. Population density of codling moth and fruit damage at harvest were kept at a low level. At the same time, population density of the pest and fruit damage in the conventionally treated orchards were higher and was serving as a reference. Based on our results, Isomate C TT dispensers may represent a promising alternative to traditional programs trying to control high initial infestation by codling moth and should be involved in the Integrated Pest Management practices on apple crops. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, VARIABILITY OF QUANTITATIVE PROPERTIES IN OILSEED RAPE - Brassıca napus L., AND EFFICIENCY FROM APPLICATION OF CERTAIN MACRO AND MICROELEMENTS(Trakya University Publisher, 2019-11-06)Iljovski, Igor, Dimov Zoran, Kabranova Romina, Arsov Zlatko, Canev Ile, Tanaskovic Vjekoslav, Dimovska DanielaDetermination of quantitative characteristics by using macro and microelements that have great importance on the development of oilseed rape - Brassica napus L. started by setting the experiment (2014), and applying Mg and Mn as elements corresponding for the purpose. The trials were set in order to see the impact of magnesium and manganese on the quantitative properties of winter oilseed rape genotypes - Brassica napus L.. For this purpose, certain concentrations of magnesium sulphate and manganese chelate by foliar fertilizer application was applied on 3 genotype winter oilseed rape (Hybrirock, Petrol and Speed) in 5 variants, as follows: Variant 1 Control Ø NPK, Variant 2 NPK+MgSO4 25%, Variant 3 NPK+MgSO4 35%, Variant 4 NPK+Mn chelate 20%, and Variant 5 NPK+Mn chelate 30%. By specifying the appropriate fertilizers with Mg and Mn (their concentrations), except for quantitative properties, the adaptability of the tested genotypes of specific agro-climatic and soil conditions was observed and the following parameters were monitored: plant height (cm), the number of branches/plant, number of pods/plant, pod length (cm), the number of seeds in the pod and seed yield (t/ha). According to the results of the preliminary experiment can be concluded that higher concentrations of magnesium sulphate (35%) and manganese chelate (30%) leads to increased the components of yield and seed in tested genotypes. Efficiency of variants, generated by certain concentrations of fertilizers has also confirmed impact of higher concentrations; in terms of dosages and prices of yields (NPK+Mn chelate 30% and NPK+Mg SO4 35%). - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Soil distribution in Crna river basin and its importance for agricultural production(University of Zagreb, Faculty of Agriculture, Zagreb, Croatia, 2020-02-21)Mile Markoski, Tatjana Mitkova, Vjekoslav Tanaskovik, Velibor SpalevićThis paper is a result of many years of field and laboratory research of the soils in Crna river basin, spread out on 497 514,81 ha, ranging from 150 to 2601 m above the sea level in order to gain a better understanding of the productive capacities of the soils and measures for their improvement. The catchment area of Crna River is a spatial area that extends in two states in the southwest of the Republic of North Macedonia and the northern part of the Republic of Greece, whose boundaries are naturally clearly defined. The filed research of the soils and preparation of soil samples has been done according to ISO 10381-1 and ISO 10381-2 protocols. In laboratory, the following analyses have been carried out on the soil samples: hygroscopic moisture; mechanical composition; pH of the soil solution; humus content and total nitrogen; content of carbonates; available nutrients P2O5 and K2O. The mechanical composition and chemical properties of the soils have been determined by standard methods.This area is very heterogeneous, with numerous relief forms, with different expositions and inclinations, and with great differences of altitude. Additionally, there are several geological formations of a very heterogeneous petrographic-mineralogical composition and climate-vegetation zones. Long-term effects of human involvement should also be noted. The vast diversity of the factors required for soil formation in catchment area of Crna River are the reason for the formation of many different soil types as well as the lower taxonomic units. There are 14 (fourteen) different soil types distributed in the Crna river basin together with a considerable amount of subtypes, varieties and forms. The most represented with the largest area are: Fluvisol, Fluvisol (Colluvial Soils) and Cambisol. These types of soils are characterized by different properties (chemical, physical, physical-mechanical and productive). Therefore, they have varied effects on agricultural production (field crop, viticulture and fruit production).
