This work presents the behaviour of two hybrids in seed growing; these hybrids, DKC 3203 (Monsanto) and Clarica 3893 (Pioneer), are simple hybrids and they are part of FAO 300-400 group. The seed batch was placed within Urleasca locality radius, Brăila county, on a chernozem type of soil, with physical and chemical characteristics which are favourable to maize plants’ growth and development, area which is characterized through a semi-droughty steppe climate, with a sprinkling system well refurbished. For the hybrids analysed, after harvest, there were determined the productivity elements (number of kernels/cob, cobs’ average weight, the weight of the kernels/cob), the yield and the quality indices, purity and germination; also, there were performed biometrical measurements (the length and diameter of the cob, and corn car’s diameter) and finally, there were determined the productions obtained. The biometrical measurements showed that the cobs of DKC 3203 hybrid have both the length (13.9 cm) and the diameter (4.1 cm) higher than the ones from Clarica hybrid, 13.6 cm respectively 3.2 cm. At Clarica 3893 hybrid, the cobs have a higher number of kernels (310.15), but the weight of the kernels on a cob (81.69 g) is smaller, due to the fact that the kernels are smaller and not equal in size, as compared with DKC 3203 hybrid, which has smaller number of kernels (304.33), but the kernels are larger (107.35 g) and more uniform. At DKC 3203 hybrid, the yield was 5.1% higher than at Clarica 3893 hybrid, this being correlated with a production higher by 205 kg/ha obtained from the same hybrid. It was observed that at the hybrid from Monsanto company, DKC 3203, it was obtained a production of 3840 kg/ha and a profitability ratio of 62.85% as against the hybrid from Pioneer company, Clarica 3983, at which there was obtained a production of 3635 kg/ha and a profitability ratio of 62.82% in the same climatic conditions and with applying the same technological elements, thus resulting that both hybrids are profitable from economic point of view in order to produce seed, due to the fact that crop’s profitability is over 50%.

Nitrogen-fixing symbiotic bacteria known as rhizobia can exist in different soils and adapt to different environmental conditions. The aim of this study was to determine the impact of pH on the growth of Rhizobium trifolii and Sinorhizobium meliloti. Rhizobial species were isolated using yeast extract mannitol agar medium) in which the pH values were adjusted to 5.0, 6.0, 8.0 and 9.0 by adding HCl and NaOH. The optimum pH for rhizobia is neutral or slightly alkaline (pH 8) and they are more sensitive to acidity. Sinorhizobium meliloti developed better in an acid medium compared to Rhizobium trifolii.

The region of Apuseni Mountain has suffered many changes over time, which is due to supra intensive exploitation of the wood mass, depopulation of villages, decreasing the number of livestock and land abandonment. The civilization of villages from „Stone Landâ€Â is represented by a specific landscape which includes reliefs forms, the pastoral construction generated by a way of life is seriously threatened by current developments. The purpose of this study was to track the time evolution of the structure of agricultural land, livestock and prospects of the area. The information about agricultural surfaces, livestock ( their evolution in time ) were taken from the Agricultural Registers of Băișoara, Beliș, Călăţele villages,  ( General Urban Plan -1998-2010-2011) , but also from villages records ( 1990-2011) from I.N.S. Cluj. Demographic data necessary for this study were taken from the 1990-2011 Censuses of Population to trace the trend of evolution of the area studied. These data were graphically processed. The results show that during the years 1990-2011, the Băișoara, Beliș, Călăţele villages have occurred important changes in the categories of land use, livestock and degree of depopulation of villages. It was found that over time, the population of the villages taken to be studied ( Băișoara, Beliș, Călăţele ) decreased and therefore changes occurred regarding land use, the number of livestock decreased and pastures are under cargo. The close relationship between the grassland condition and number of animals and degree of intensification of crop systems determines the direction of their evolution.

In the context of issues regarding ecology and environmental protection, a particular role is played by efficient waste management. This paper presents a modality for managing waste that has been less considered, i.e. polystyrene waste used in packaging for the protection of various products during transportation. The study establishes the maximum proportion of replaced sand in the aggregate used, a proportion allowing to maintain the technical characteristics of acceptable plastering mortar. This is demonstrated by the results of physico-mechanical determinations performed in test samples. The determinations show that the resulted mortar is a material with good thermal and sound insulating properties.

In this paper, author collective present results and methodology of the insecticides testing against maize leaf weevil, in laboratory conditions. Year by year at NARDI Fundulea, in field conditions, it has tested insecticides used both like seed and vegetation treatment for control ling of the maize leaf weevil. Because climatic conditions from the spring are not favorable for this pest every year, laboratory testing is one of the best methods for evaluate of the insecticides used like seed treatment. At eight days after insects are added in the pots with maize plants, highest adults mortality and lowest attack intensity has registered in case of plants emerged from the seeds treated with products on base of thiametoxan ( Cruiser 350 FS ) , clothianidin ( Poncho 600 FS ) or thiametoxan+teflutrin ( Force Zea ) . In case of seeds treated with product on base of imidacloprid ( Nuprid 600 FS 8,0 l/t ) , even if the insects mortality was lower, the attack intensity has low values. All plants from the untreated variant were destroyed. At treated variants, saved plants percent were at least 90 %. Seed treatments provide a satisfactory protection of the maize plants, in first vegetation stages against maize leaf weevil.

Concerning the management of durmast seedlings cultures in nurseries, the main methodology applied for enhancing their development and resistance against diseases, relies on the following issues: irrigation, high biological value seedlings, mechanization, disease fight specific chemicals, and, at last but not at least, an appropriate fertilization. The aim of this paper is to identify of the most efficient fertilizing option, in order to form an important variable for increasing the resistance to the powdery mildew attack. The trial was carried on during experimental year 2009 in a durmast nursery from Transylvanian Plain. During vegetation period, the attack degree of Microsphaera abbreviate was recorded. A monofactorial design was put into practice, using 3 variants. Basic statistic and correlations were calculated using STATISTICA v. 7.0. The biggest attach degree of Microsphaera abbreviata on durmast seedlings was recorded in the variant where fertilization was performed with maximum mineral fertilizer dose, N80P80K80 (6.31%), respectively, followed by attack degrees recorded for other mineral fertilizer doses N60P60K60 (5.54%) and N40P40 is classified on the 5th place. Our trial shows that N80P80K80 with poultry manure is the fertilization solution, which confers to durmast seedlings the biggest resistance against the attack degree of Microsphaera abbreviata mushroom.

Hammer mills are machines used in agriculture to obtain concentrated fodder mix. The hammer mills grinding materials is produced upon impact of the hammer material and crushing plate located inside the grinding chamber. Depending on the hammers rotor assembly mode, the following types of mills can be used: hammer mills articulated and fixed hammer mills.
