The goal of three-year investigations was to determine the influence of precipitation upon the drainage discharge in two different climatic regions (Croatia and Lithuania) at two different pipe drainage spacing in each region (first region with 15 m and 20 m drainage spacing and second region with 12 m and 24 m drainage spacing), to calculate the soil water balance according Thornthwaite's method and compare the measured drainage discharge and the calculated surplus of water in soil. Investigations were carried out at the experimental amelioration sites in the central Sava River Valley (Croatia) on hydroameliorated Gleyic Podzoluvisol soil and in Middle part of Lithuania on hydroameliorated Hypogleyic Luvisol soil in the period 2009 - 2011. The research results showed that the drainage discharge and its duration depended on the amount and distribution of the precipitation during the study period. There isn't difference in the total drainage discharge between the tested drainpipe spacing in each investigation year, but there are differences in the duration of the drainage discharge both on an annual scale and depending on drainpipe spacing. In each year, the duration of drainage discharge was smaller at the 12-15 m drainpipe spacing than at the 18-20 m drainpipe spacing. The calculated surplus of water followed the monthly amounts of precipitation, but in all years was higher than the drainage discharge. The 12 to 15 m pipe spacing is more efficient for draining the surplus water from drained soils, since the surplus of water from soil is drained in a shorter period of time and better water-air relationships in soil are created faster, which is a prerequisite for timely application of agricultural management practices on hydroameliorated arable areas.

Technological characters determine the so-called technological - commercial quality of tobacco and tobacco products during fabrication. Three-year trials were performed with variety YK 7-4/2 (check) and three Basmak varieties - MK-1, MB-2 and MB-3. The trial was designed in randomized blocks with five replications. The aim of investigation was to determine water retention capacity, density, filling capacity and fractional composition of tobacco by insertions. WRC was determined by the method of ( Boceski, 2003), filling capacity (cm 3 /g) and density (g/cm 3 ) were determined using the Borgwaldt densimeter by the method of Shuto (1972) and fractional composition by the method of Dorahova and Dikker. During the three years of investigation, WRC ranged from 16.87% in the lower leaf of variety MB-2 to 23.70% in the middle leaf of MB-3, which proves that the investigated varieties of Basmak tobacco have higher WRC compared to the check. The lowest density by insertions and years and the highest filling capacity was recorded in the middle leaf of MB-2 in 2009 (0.195 g/cm 3 ). In the three years of investigation, the lowest average density was recorded in lower leaves of the variety MB-3 (0.213 g/cm 3 ) and the highest in top leaves of the check variety YK 7-4/2 (0.303 g/cm 3 ). The filling capacity was the highest (5.13 cm 3 /g ) in middle leaves of the variety MB-2 and the lowest (2.91 cm 3 /g) in undertop leaves of the variety MB-3 in 2009. In average, the lowest positive fraction was measured in lower leaves of the variety MB-2 (78.99%) and the highest in middle leaves of the variety MB-3 (93.23%), while the negative fraction ranges from 10.16% in MB-3 to 21.11% in the check variety JK 7-4/2. The data obtained show that the characteristics of the investigated Basmak varieties are typical for the oriental tobacco. presented by insertions: water retention capacity, positive and negative fraction, density and filling capacity.

The consumption of vegetables is one of the most important pathways for heavy elements to harm human health. Direct deposition of contaminants from the atmosphere onto plant surfaces and accumulation of heavy elements in flooded arable soil are of great concern because of the potential health risk to the local population. Thus, the present study was carried out to analyse distribution and soil-plant transfer of Pb, Cd, As, Co, Cr, Ni, Cu, Mn and Fe in potato, carrot, celery, parsnip and onion in order to evaluate their potential effects on human health. Total content of heavy elements in 26 vegetable samples collected from different flooded fields was analysed by atomic absorption spectrometry with a graphite furnace (AASGF) after microwave digestion of the analysed samples. Average concentrations of lead (Pb) and cadmium (Cd) in some of the investigated vegetable samples were higher than maximum allowable concentrations set by EC/Serbian regulation. On the other hand, arsenic (As) was not detected in any of the analysed samples. Accumulation and translocation of analysed elements were varied from element to element as well as among selected vegetable crops. The results showed that the parsnip had highest uptake for the most analysed elements (Fe (107 mg/kg) ˃ Mn (6.98 mg/kg)˃ Cu (1.94 mg/kg)˃Ni (0.34 mg/kg)˃ Pb (0.13 mg/kg) compared with the other investigated crops. The bioaccumulation factor (BA) for analysed elements in different vegetables was found in order of Cd (0.08)˃Fe(0.07)˃Cu (0.06)˃Pb (0.01)=Ni˃Mn (0.001), indicating that analysed crops are categorized as excluder (BA<1). The total health risk associated with the consumption of investigated vegetables grown in studied flooded arable soil was assessed using target hazard quotient (THQ). The THQ values estimated for investigated crops were notably below the safe limit of 1, except for Mn (2.10) and Fe (11.65).

The aim of the paper is to raise, direct and encourage awareness of the importance of biomass in energy production, as well as to present various possibilities of its use. Increasing demands for energy and growing environmental issues impose the need for energy production from renewable resources. Fossil fuel reserves are finite and their deficit is projected for the coming period. Biogas is one of the renewable resources. The said gas consists of a large amount of methane gas produced by fermenting organic substances from biomass, manure or any other biodegradable material in anaerobic conditions. Electricity production from renewable resources on farms needs to meet numerous conditions, such as environmental protection, bio-safety and animal welfare, as well as a series of technical, organisational, construction, manufacturing and economic requirements imposed by this kind of production. The Lazar Company Ltd. from the town of Blace owns a farm with 600 dairy cows, a dairy which processes 60 000 litres of milk per day, as well as an energy production plant based on biogas, with the capacity of 1mW/hour. In addition, special attention is paid to organic farming, where biomass is said to have multiple applications in energy production in the context of a long-term development trends of certain industries.

In this review the focus is on few agricultural energy crops, which means crops that are grown exclusively or primarily for the purpose of producing biomass for energy purposes in an agricultural rather than a forestry context. However, cultivation of most of these crops is restricted to certain regions, e.g. by requirements for a certain climate zones. Having in mind the similar agro ecological conditions in R. Macedonia and Bulgaria, but also needs of the crops for successful growth and development, species as miscanthus , switch grass and sweet sorghum are introduced as a potentially used energetic plant species for this part of the Balkan region. optimum N rates for switchgrass varied, from 50 – 110 kg ha -1 year -1 (Planting and Managing Switchgrass as a Biomass Energy Crop) up to 160 – 220 kg ha- 1 year -1 (Is switchgrass a low nutrient input crop or not?). Split applications are more suitable for rates greater than 100 kg ha -1 or for a two-cut harvest system. Investigations from Muir et al., (2001) and Parrish and Fike (2005), reported little or no yield response of switchgrass to phosphorus fertilization. Hovewer in soils with low plant available P, application of 45 kg P ha −1 increases biomass yield by up to 17% (Kering et al., 2012). The single use of potassium (68 kg ha -1 ) did not affect the yield level. Applied together with N (135 kg ha -1 ) has positive influence of increasing yield, indicating that for maximum biomass production, proper nutrient management (N, P, and K) is required (Maru et al., 2013).
本审查的重点是少数几种农业能源作物，即在农业而不是林业环境中专门或主要为生产用于能源目的的生物质而种植的作物。然而，大多数这些作物的种植被限制在某些地区，例如由于某些气候带的要求。考虑到马其顿共和国和保加利亚相似的农业生态条件，以及作物成功生长和发育的需要，我们引进了芒草、柳叶草和甜高粱等物种，作为巴尔干地区这部分地区潜在的能源植物物种。柳枝稷的最佳施氮量不同，从50 - 110公斤公顷-1年-1(柳枝稷作为生物质能源作物的种植和管理)到160 - 220公斤公顷-1年-1(柳枝稷是否是低营养投入作物?)分开施用更适合于大于100公斤公顷-1或两次收割系统。Muir等人(2001年)和Parrish和Fike(2005年)的研究报告称，柳枝稷对磷肥的产量响应很小或没有。然而，在植物有效磷含量低的土壤中，施用45公斤磷肥每公顷可使生物量产量提高17%(开云等，2012)。单施钾肥(68 kg / h -1)对产量无显著影响。与氮肥(135 kg ha -1)一起施用具有提高产量的积极影响，这表明为了最大限度地生产生物质，需要适当的养分管理(N、P和K) (Maru等，2013)。

The genotype specificity in the uptake of the main nutrients according to the fertilization rate was investigated in Triticum aestivum L. varieties under conditions of a vegetation experiment. Four fertilization rates were tested: N 0 P 0 K 0 , N 200 P 200 K 200 , N 400 P 200 K 200 and N 600 P 200 K 200 . The response of the varieties to the nutrition conditions provided was studied during several stages of growth and development. The different nutrition regimes used lead to manifestation of the specific abilities of the varieties to take up nutrients. Genotype and mineral fertilization had a higher effect on nutrients uptake than stage of development. During the initial stage of wheat development, the differences established in the uptake of macro elements were greater between the varieties than between the individual fertilization rates. The differences were most evident at maturation. This specificity was well expressed in nitrogen and phosphorus uptake in total biomass and to a lesser extends - in potassium uptake. Varieties Slaveya and Milena had highest amounts of nitrogen uptake in grain.
在植被试验条件下，研究了不同小麦品种对主要营养物质吸收的基因型特异性。试验了4种施肥水平:N 0 P 0 K 0、N 200 P 200 K 200、N 400 P 200 K 200和N 600 P 200 K 200。在不同的生长发育阶段，研究了品种对所提供的营养条件的反应。不同的营养制度导致不同品种吸收养分的特殊能力的表现。基因型和矿质施肥对养分吸收的影响大于发育阶段。在小麦发育初期，品种间对宏量元素的吸收差异大于单个施肥量之间的差异。这种差异在成熟时最为明显。这种特异性在总生物量的氮和磷吸收中表现得很好，在钾吸收中表现得较少。品种Slaveya和Milena籽粒吸氮量最高。

The aim of this study was to determine the effect of different irrigation regime on winter wheat yield and water-use efficiency (WUE). The field experiment was carried out between the year 2009 and 2011 at Murted Basin in Turkey with 4 different irrigation treatments which was Rainfed (RF), Full irrigation (FI), Moderate irrigation (MI), and Deficit irrigation (DI). Soil moisture was measured with neutron probe. According to results average wheat yield was obtained 3.35 t ha -1 , 4.54 t ha -1 , 4.22 t ha -1 and 4.31 t ha -1 and average harvest index was 29%, 31%, 32% 31% and 32% for RI, FI, MI and DI irrigation treatments respectively. The highest WUE value with 9.1 kg m -3 was calculated at DI treatment. A significant negative correlation was found between grain yield, total harvested biomass and the WUE. The results presented in this work suggest that the amount of soil water content affects grain yield and water use efficiency. It might be recommended that irrigation concentrated in the after heading period (DI) increase WUE in semi-arid climate condition such as Central Anatolia Region of Turkey.
本研究旨在探讨不同灌溉制度对冬小麦产量和水分利用效率的影响。本试验于2009 - 2011年在土耳其Murted盆地进行，采用雨灌(RF)、充分灌(FI)、适度灌(MI)和亏缺灌(DI) 4种不同的灌溉处理。用中子探针测定土壤水分。结果表明，RI、FI、MI和DI处理的小麦平均产量分别为3.35 t ha -1、4.54 t ha -1、4.22 t ha -1和4.31 t ha -1，平均收获指数分别为29%、31%、32%、31%和32%。DI处理的WUE值最高，为9.1 kg m -3。籽粒产量、总收获生物量与水分利用效率呈显著负相关。研究结果表明，土壤含水量影响粮食产量和水分利用效率。在土耳其中部安纳托利亚地区等半干旱气候条件下，建议在抽穗期后集中灌溉以提高水分利用效率。
