Abstract: The research showed that by quick conditioning, the external layers of the grain get better moisture than the internal ones and this type of proportion is being kept in a certain amount until the end of the grinding. The maximum heating of the wheat is determined by the temperature action upon the protean complex. For the wheat with a poor amount of gluten a more powerful heating must be used and for the wheat with normal amount of gluten and mostly for the one with a rich amount the heating must be more reduced. The heating temperature must be established according to the wheat quality and the degree of improvement of the baking features followed by the action of heat when applying the quick conditioning method. Steam treatment of the wheat grains is the main composing element of the quick conditioning process that exerts the most intense act on the milling proprieties and wheat baking.

Abstract: From the research made on the hygroscopic proprieties of cattle cakes we can say that these absorb vapors from the surrounding atmosphere and the quantity of absorbed vapors is bigger if the relative air humidity is bigger.The oleaginous cattle cakes not only have the ability to absorb water but they can also give it away when surrounding atmosphere humidity goes down. It was shown that at the hydrating and dehydrating process of the cattle cakes in an environment with different relative humidity the balance values of the water content do not coincide - the hysteresis phenomenon. It was shown that cattle cakes with the water content above 11 – 13% kept a longer period of time at relative air humidity above 71% had fungus growth.

Abstract: Generally the maize yield per unit area responds to density changes. Optimum plant density for maximum grain yield per unit area may differ from hybrid to hybrid. Objective of the study was: to estimate the optimum density for maximum grain yield per unit area to seven hybrids, the density impact on stand uniformity,  to evaluate how some hybrids, important yield parameters (yield per plant, ear length and kernel row number) respond to density changes. Experimentation was conducted at the Agricultural Research Station, Turda, Romania, during the 2006 and 2007 seasons under natural conditions, without irrigation. Seven single-cross hybrids (FAO 320 - 450) were grown at three densities (2.5, 4.2, 8.4 pl/m2). Comparison of means was conducted by least significance difference (LSD) after analysis of variance for a two-factor split-plot design. In maize culture should take the necessary measures to achieve the optimum density for the chosen hybrids and the most uniform stand possible.

Abstract: Spring barley malting varieties (Ebson, Malz, Nitran) and their response to environmental conditions, year and fertilization were investigated in 3-years experiment (2005 – 2007). Treatments of fertilization: 1. control, 2. LAV (ammonium nitrate with limestone) 20 kg ha-1 of net nitrogen, 3. LAV for grain yield level of 5 t ha-1 applied at the end of shooting, 4. DAM 390 (ammonium nitrate with urea) in rate 20 kg ha-1 of net nutrient N applied at the end of shooting. The highest yields of grain were achieved in 2005 and the lowest in 2007, which demonstrated the statistically significant influence of year. The lowest yield was at control variant – 5.09 t ha-1. The average yields of grain in 3-years period were: Ebson – 6.82 t ha-1, Nitran – 5.74 t ha-1 and Malz – 5.46 t ha-1. Following parameters of grain quality were evaluated: thousand kernel weight (TKW), kernels bulk density and proportion of grain over the sieve 2.5 mm.

Abstract:  The paper present a research on the productivity of oat-lentil intercropping, for evaluating his adaptability on natural conditions of South Romania and ecological cultivation. The experiment was carried out in the spring of 2008, in Moara Domneasca Experimental Field, on reddish preluvosoil, in randomized variants, in 4 replications. The seeds used for experiments were ecological. Oat and lentil were sown in alternating rows, in 12.5 cm distance between rows, at a 3-4 cm depth. Oat had a density of 200 seeds/m2 and lentil of 150 germinable seeds/m2. It was determined productivity elements, land equivalent ratio and yields. Average grain yield for oat in monoculture was of 2386.5 kg/ha and in intercropping with lentil was of 1767.5 kg/ha. In monoculture, lentil yield was of 1403.3 kg/ha and in intercropping with oat, it was obtained 780.4 kg/ha. The value of the land equivalent ratio (LER) in the oat-lentil intercropping was 1.29, which means that it is a real advantage of this type of crop system comparatively with oat and lentil raised in monoculture.

Abstract:  The research was made with the purpose of establishing the varieties on which, in the favorable pedoclimatic conditions for rape from the Vest Plain in our country, can be obtained the highest oil productions. In this way, was studied to the influence of the fertilization upon the oil content, at an assortment of seven rape varieties. The researched biological material was formed of seven rape varieties new for the reference area, as follows: Valesca, Orkane, Ader, Potomac, LG, Belini, Milena. To point the negative effect of the nitrogen fertilization, to optimize the doses upon the oil content, was accounted the agrofond dose, in domain N0-N150. The research was made on a fund of P80 K80, so that varieties can expose their productive potential and the specific oil content. The results obtained accentuated the fact that the seven rape varieties studied, in the fertilization domain N0-N150, the oil content varied between 43,1% and 47,7%. The highest oil content was registered on Milena variety. The oil production was calculated on the base of the determined oil content and the seeds production. Fertilizers with nitrogen, negatively influenced the oil content, at all the studied varieties, the oil content being inferior on the agrofond fertilized with nitrogen, towards the agrofond that wasn’t fertilized with nitrogen. The researches results are important for the growers, because they increase the possibility to obtain oil productions higher than 1t/ha.

Abstract: Maize is the first-ranged field crop in Serbia and Croatia (harvested area status in the 1996-2007 decade period: 1264000 ha and 296000 ha, for Serbia and Croatia, respectively). Aim of this study was testing maize yield variations over the years in Serbia (Kragujevac and Zajecar regions = KGr and ZJr) and Croatia (Osijek–Barannya and Zagreb Counties = OBc and ZGc) with emphasis on precipitation and temperature regime impacts. Weather characteristics of two growing seasons (2000 as less favourable year or LFY and 2005 and more favourable year or MFY: comparison data of Kragujevac = KG and Osijek = OS Weather Bureaus) could be used as a typical examples of precipitation and temperature regime influences on maize yields under middle and eastern European environmental conditions. Precipitation for three months (June–August) period of LFY 2000 was in KG 71 mm or only 35% of long-term mean (LTM) and in OS 78 mm or 37% of LTM. At the same time, air–temperatures were 22.90C (KG) and 22.60C (OS) or 2.50C (KG) and 2.30C (OS) higher in comparison with LTM. As result of water shortage and high temperatures stresses, maize yields in tested areas were only 1.78 t/ha (KGr) and 3.96 t/ha (OBc). However, under MFY 2005 conditions, precipitation in three summer months in KG were 255 mm (or 25% higher than LTM) and in OS even 521 mm (or 1.5 times more than LTM), while air–temperatures were in level of LTM. As results of favorable weather conditions were maize yields 4.27 t/ha (KGr) and 6.98 t/ha (OBc) or 140% higher (KGr) and 76% higher (OBc) compared to yields in these areas under LFY conditions.

Abstract: In the decade period 1998-2007 maize harvested area in Croatia was, depending on year, from 288380 ha to 407272 ha while annual yield variation was in range from 3.93 t/ha to 6.92 t/ha. The region eastern Croatia represents 22 % of the state territory, it participating in maize harvested area near to 50 % and maize yield in this region is near to 20% higher compared to the state level. Mean air-temperature in Osijek for May-August period (the decade 1998-2007) was 20.7 oC  or for 1.5 oC higher compared to 30-year (1961-1990) mean. At the same time, precipitation was for 9% higher. Depending on year, precipitation in May-Aug. period were in range from 104 mm to 567 mm and air-temperatures from 19.1 oC to 22.5 oC or from  –61% to +110% (precipitation) and from -2 % to +17% (air-temperature) deviation from 30-year means. The growing seasons 2000, 2003 and 2007 were less favourable for maize because of drought and the higher air-temperatures. For example, in the period May-August precipitation in Osijek were for 61 % (2000), 39 % (2003) and 40 % (2007) lower (2003) in comparison with 30-year mean. At the same time, air-temperatures were for 2.3 oC, (2000 and 2007) and for 3.2 oC (2003) higher. Under these conditions, maize yields in the region were lower for 28% (2000), 25% (2003) and 18% (2007) compared to the decade mean (6.01 t/ha).

Abstract: Two data sets have been used in this analysis of climatic conditions and their effects on sugarbeet yield. The first is a period from 1963 to 2007; the second is a period 1988 - 2007. Both periods were as analyzed for the same parameters. A comparison of the two data sets indicated that the average temperature for the growing season was increased by 0.40C (2.2%), the precipitation by 13 lm-2 (3.5%), ETR (actual evapotranspiration) by 4 lm-2 (1%), and the precipitation deficit by 10 lm-2 (5.6%). However, the overall picture changed when the climatic data were partitioned into three sub-periods, the dry sub-period (25% of the analyzed years), the average sub-period (50% of the years) and the humid sub-period (25% of the years). When the data were analyzed in that fashion, the drought became pronounced in the dry years, slightly increased in the average years and practically insignificant in the humid years. Unfortunately, yield performance did not follow this trend in climatic conditions, particularly not in the humid years.

Abstract: The knowledge of strong wind climatology is important for the precise forecast of their occurrence and also for the elaboration of efficient protection methods against their harmful effects. In meteorology, strong winds are defined as atmospheric phenomena characterized by air currents with a speed of ≥ 15m/s (calculated for a time period of 2'). In the synoptic activity, the average wind speed of ≥ 10m/s (calculated for a time period of 10') is included in the category of “warning messages”, characteristic to the dangerous meteorological phenomena. The strong winds represent one of the risk hydrometeors with particular impact on the agricultural activities (especially on the tree and vine culture). The well-known marine breezes are formed close to the sea (up to 15-20 km inside the province) and they influence positively the relative air humidity but also contribute to a decrease in the rain regime. Thus, Dobroudja has been known as the land of winds since Antiquity. The wind speed is between 18-90 km/h, while the frequency is up to 85%, the dominant directions being north, north-west and north-east (43.8%), then south and south-east (30.4%).

Abstract: In our country, the problem of the structure crops has an important place, since the proportion of large grains which required by the national economy and the decreased number of agricultural species grown since 1990 at the country level. This requires systemic thinking and a complex view from the experts and practitioners, as regards the rational crop rotation respecting the principles of modern and efficient agriculture. Regarding maize, the data obtained in 9 years of testing shows that have a better behavior in monoculture than wheat. Borcean I., (1992) show that in the extended monoculture of corn reduces humus content, the structure degrades, a progressive acidification of the soil, the soil is exhausted in the macro and micro elements recommending the use of rotation for 4-6 years. Results from the world shows that fertilization contributes 30-50% to increase yields per unit area, the most cultivated plants and products from various countries of the world are closely correlated with the types and doses of fertilizers used.

Abstract: Cotton is a thermophile plant, whose geographical area does not exceed the 45° parallel to the north. However, at this latitude, it does not always mature. The sum of temperature degrees needed by this plant to mature is 3200-2800°C. The minimal temperature for germination is 12°C, while the sunlight duration must be at least 1 500 hours. Even though water consumption is high, cotton can withstand drought (a frequent phenomenon in Dobrogea) better than other plants such as certain cereals, for example. The fertilized cultures can withstand drought better than the unfertilized ones. Cotton vegetates normally at a rain regime of 400-500 mm yearly, if at least 200 mm and at most 300 mm fall between May-August (the rain excess during summer is harmful because the heat and light are reduced during rain, causing thus a delay in ripening and consequently a diminished production). In regards to the soil, cotton needs fertile soil with good drainage that allows air, heat and water to enter the layers explored by the roots. Currently, there are no cotton cultures in Romania, but the Dobrogea plateau offers proper soil and climate conditions in certain regions.

Abstract: The crop rotation has slow effects, which show their results in time, influencing the fertility through their structure and the alternant crops, mainly due to the effect of the precursory plant. Its action has a biological nature, which manifests itself in the quantity of the organic remains left in the soil, the root secretions, biological processes of discomposure and synthesis, all finally reflected over the yield. The precursory plants for the autumn wheat must respond to the following requirements: they have to clear the area as soon as possible during the summer, so there is left enough time to prepare the soil in the best conditions and for the realization of the sowing in time; they have to leave the area clear from weeds, with improved physical and chemical characteristics and with a high content of organic matter and nutritive substances. In order to emphasize the importance of crop rotation the quantitative and qualitative production of the Dropia autumn wheat cultivar has been analysed in the conditions of monoculture sowing, wheat – corn rotation and wheat – corn – pea rotation.

Abstract: The study of the interaction of several factors, in the case of wheat yield technology, lead to the elaboration of various and more precise conclusions, than in the case of a single factor experiences. Due to the previously mentioned information, I have analyzed the interaction of the technological factors used in the yield process of the Dropia autumn wheat cultivar seeds, in order to deal with a more precise interpretation of the overall effects of these factors. In order to obtain a bigger and constant production per hectare, efficient under the economical aspect, the appliance of the nitrogen fertilizers must take into account the necessities of the wheat implied for this element and the level of supplies present in the soil. Due to this fact, the appliance of the chemical nitrogen fertilizers becomes necessary and compulsory in order to ensure the continuous nourishment of the plants with this element, essential for their natural evolution. To emphasize the favorable effect of the use of the nitrogen fertilizers, the interaction between the fertilization level with nitrogen and the sowing period, the interaction between the fertilization level and the sowing density were analysed. The interaction between the sowing period and the sowing density was analysed too.
Key words: wheat, fertilization, relative yield, sowing period, sowing density.

Summary:   This paper presents the results of researches from SCDA Caracal, regarding the dynamic of ammoniacal nitrogen on chernozem in condition of irrigation function of the method of soil tillage and fertilization. The experiment took place over a period of three years and regarded the following factors: A factor – irrigation, B factor – the method of soil tillage with 3 phases, C factor – nitrogen fertilization on constant fund of phosphorus with 4 phases. The content of ammoniacal nitrogen is presented on the dates it was taken as sample during the vegetation period at 0-20 cm depth. The dates for samples were: November 1, before applying the first dose of nitrogen, December 8, after 30 days from the first dose, April 25 after 30 days from the second dose and July 28 when the plants were mature.   The determinations regarding the dynamic of ammoniacal nitrogen in the soil for wheat culture, highlight important aspects, but also the effect of soil tillage, creating new situations nitrogen supply for the plants. The analyses regarding the content of ammoniacal nitrogen were made in the last year of experiments. Analyzing the content of ammoniacal nitrogen function of the soil tillage, we recorded values almost similar at the sample dates after using different machines. There are differences between the normal plough at 18-23 cm (6.23 ppm N-NH4+) and chisel at the same depth (6.94 ppmN-NH4+) or at 8-10 cm depth (6.46 ppm N-NH4+).

Abstract: The paper presents the results of the researches carried out at the Agricultural Research Station Oradea, between 1996 and 2002, regarding agricultural yield of spring wheat, cultivated on a luvosoil polluted under control with oil brought from the exploitation site at Suplacu de Barcãu, Bihor County. The experimental device was made out of micro parcels of 1 m², set up in a randomized manner, in a Latin square, polluted with a concentration of: 0, 1, 3, 5 and 10 % (0, 3, 9, 15, and 30 l/m²), oil in the ploughed layer, in 4 repetitions. The experience was than cultivated with in the first three years with millet, a plant that is considered to be resistant to pollution, and than until 2002 with spring wheat. The analysis of the yield losses from the parcels polluted with oil in various concentrations, have shown that these decreases in time, becoming insignificant after 7 years in the concentration of 1 %, 8 years in the concentrations of 3  - 5 %, and 9 years for 10 %. This shows the biodegradation of the oil without any sort of agropedomeliorative measures. By analyzing the correlations between the wheat yields in the last 7 years of research and the climate factors (rainfall and air temperature) registered in the vegetation period, very significant square, spatial polynomial correlations were established for each oil concentration. The fact that correlation report decreases from 0.7458, for the parcels unpolluted (0 % oil), to 0,4170 for the parcels polluted 10 % oil points out the influence of the increase of the pollutive agent.

Abstract: Research was carried out in an area that is very favourable to bread-making winter wheat and aimed at improving cultivar structure and fertiliser response with effect on yield and quality features. We set comparative crops with 10 cultivars developed in România, Serbia, and Hungary. The studied cultivars were Alex, Ciprian, Dropia, Flamura 85, Faur, Krystina, Lilijana, Mina, Mv Marsall, and M.V. Palma. Fertilisation levels were N0P80K80, N80P80K80 and N100P80K80. Experiments were of the bi-factorial type and organised after the sub-divided plot method with 3 replications. The soil type on which research was carried out was carbonatic, gleyed aluvisoil. Soy was the pre-emergent crop. Upon harvesting, we measured hectolitre volume, protein content, moist gluten content, deformation index, gluten quality index, and fall index. Results contribute to the establishment of a cultivar structure for the mentioned area and of fertilisation improvement with a view to obtain high yields with superior bread-making features.

Abstract: The study of the nitrogen fertilizing influence during maize seeding on the sprouting and growing vigor uniformity in the main hybrids cultivated in Transylvania, using different calibers seeds, is presented in this paper. This study was performed starting from the assumption that ammonium nitrate dissolution near maize seeds is an endothermic process and this could influence the germination processes and manifestation of their vigor. Experimental results obtained shows that nitrogen application on the sowing line may have contradictory effects. Nitrogen large seed induced a reduction in the rate of sprout vigor and growth, and seed size smaller growing stimulates growth and vigor of plants.
