Urban agriculture is a concept that has great potential growth in developed countries, where the urbanization rate will increase by FAO data to 65%, by the year 2025. The rate of urbanization is growing also in the other countries, sustainable development of the developing countries an urban development of rural areas, e.g. situation of Romania. Feeding and especially the food which contributes to the growing urban population health becomes an issue of national strategy. The role of fruit in general and ecological in particular, especially remarked in balanced dietis certainly undeniable. For this reason is therefore very important to encourage the increasing number of trees in urban area sand of course the diversification of species and varieties of trees and shrubs grown. Successful implementation of such a strategy is based among others on knowledge. In this knowledge, we want to make our contribution by presenting the results of research synthesis developed over the years 2007-2014 at USAMV Bucharest, regarding the fruit growing ecosystem sustainability and increasing the diversity of species and varieties of trees and shrubs adapted to the urban agriculture.

Initially, each soil type has a certain level of acidity depending on the composition, the natural vegetation, the amount of rainfall and various other factors that cause changes in soil pH over time. Soil amendment in order to obtain an optimal pH improves also the yields for long-term. This paper refersto the selection of an agriculture lime material to be used in experiments on acidity correction of an acid soil. In Romania, according to official data are obtained annually approximately 75 000 t of steel slag. If the slag is not dangerous for the environment and public health, then the priority should be given to the use of recycled materials. Considered an unconventional amendment, steel slag was selected taking into account its quality and association with legislation. Steel slag presented an Amendment Neutralization Potential very high (ANP = 114%) reported to the content of calcium oxide and magnesium oxide. Steel slag can be considered a mineral amendment used to improve soil acidity, and also a source of calcium and magnesium. Using steel slag as amendment for acid soils can be considered a potential and significant environmental risk, which is why the whole process of amendment must be conducted in terms of environmental protection.

The recently emerged interest in using renewable vegetable sources as feedstock for biofuel production requires the identification of effective solutions aimed to follow the principles of sustainable development. Biofuels from the first generation were produced from sugarcane, starch and oils derived from agricultural products, but they may not be sustainable because are competing with the agricultural production. Currently, studies are focused on the obtaining of a second generation of biofuels that originate from plants other then food crops, from agricultural residues and from municipal wastes. Being economically attractive and having certain agro-technical advantages, the Camelina sativa seed oil is considered a sustainable source for obtaining second generation biofuels. The aim of the present research was to record the effect of genotype in 3 foreign varieties of Camelina sativa (CALENA, GP 204 and GP 202) and in 3 autochthonous ones (CAMELIA, one local population Fundulea and one hybrid line) as regards both the growth characteristics and the yield components in a greenhouse experiment, in order to evaluate their potential performance and adaptability in field conditions. Periodic phenological observations were performed on the occurrence of flowering, on the pod maturation and genotypic differences of the biometric measurements such as plant height, number of branches, number of pods per plant, number of seeds in pods and thousand seed weight are discussed.

Livestock genetical structure improvement from one generation to another request, among others, the knowledge of their genetical parameters. The guidance of livestock genetical structure involves the knowledge of the share caused by genetical and environmental factors concerning the variability observed at the livestock level. The knowledge of heritability coefficient values makes easy the livestock genetical improvement, this one indicating the resolution of the traits to be improved. In this respect, there was estimated the milk production heritability, of the protein percent, of the fat percent, in a line of Holstein-Friese, during three generations. The heritability coefficients analysis, estimated by means of the interclass correlation method, for the three traits in the lactations dynamics, emphasized different values from one lactation to another, values justified by different sample genetical structures and respectively the different environmental conditions where these ones evolved. With little exceptions, the heritability coefficients values were comprised between 0.2 and 0.4, values which frame the traits within the group of those intermediary heritable. This genetical determinism of the analysed traits within the line of Holstein-Frieserecommends that this one may be relatively easy to improve.

This paper aims to monitor the cherry fruit fly, as well as for possible actions to combat it by non-chemical methods. The Entomology Department of the USAMV Cluj-Napoca in collaboration with the UBB Cluj-Napoca researchers, started a study regarding the functionality of some Semi-chemical products to attract adults of Rhagoletis cerasi L. The chemistry research laboratories synthesized them and then, under natural conditions, screening studies of their attraction power were performed. The experiment was conducted over two experimental years, 2016 and 2017. Six variants of semiochemical formulations were tested: 2-hexanone, 3-heptanone, nonanal, beta-felandren, geranil acetate and (+) –limonen. The V6 variant that blends the acetylation made most capture. Therefore, the mixture of volatile substances in this variant may present a higher level of attractiveness.

Maize leaf weevil (Tanymecus dilaticollis Gyll) produce high damages at maize crops, in south and south-east of the Romania. Until end of the year 2013, seed treatments were generalized. After neonicotinoid treatment restrictions, as result of EU directive 485/2013, no insecticides remain available, for maize seeds treatment, against T. dilaticollis, in Romania. As result, researches from last years were focused for finding possible alternatives to replace neonicotinoid insecticides, used for maize seed treatments, in eventuality of permanent ban of these, in 2016. In this paper, authors collective present results concerning testing of two active ingredients (cyantraniliprole and thiacloprid), for controlling of the maize leaf weevil, used high pest pressure, in laboratory conditions. The results obtained at variants treated with cyantraniliprole, thiacloprid or different combinations of these two active ingredients were compared with one standard active ingredient, clothianidin and control (untreated) variant. In this laboratory assessment, in conditions oh high pest pressure, after 8 days from pots infestation with T. dilaticollis adults, higher insect mortality was registered in case of variant treated with clothianidin active ingredients (67.50%). At the rest of the treated variants, insects mortality, after 8 days of observations, presented low values, ranged between 6.25 and 12.50%. On a scale from 1 (not attacked) to 9 (total damage), attack intensity of the T. dilaticollis at the maize untreated plants, was of 8.67. In conditions of high pest pressure, untreated plants were destroyed. The lowest attack intensity values was registered in case of variant treated with clothianidin active ingredient (I=3.92). Cyantraniliprole and thiacloprid active ingredients didn’t provide effective protections of the maize plants, in first vegetation stages (BBCH 10-14), against T. dilaticollis attack, in conditions of high pest pressure.

Ourdays, the identification of friendly solutions in order to enhance physiological development of cereals is one of the main priorities of agriculture. This approach, also contributes to the promotion of the practices of the sustainable agriculture. A practice, which occupies more and more space is the use of endogenous type substances, as phytohormones, in order to increase cereals’ physiological development, and nutritional traits. This is the context where the aim of our study is placed, meaning that we focused on determining the effects of GIBB A3 phytohormone on two maize hybrids content in macro-, and microelements, within specific environmental conditions of Transylvania. Two maize hybrids were studied, Turda Star, and Turda 200, respectively, and their elemental content was quantified by AAS, and raw data were processed with IBM SPSS Version 20. The results of our trial show the influence of GIBB A3 hormone upon the analyzed macro- (K, P, S, Cl, Mg, Ca), and microelemental (Fe, Mn, Zn) content of studied maize hybrids, mainly K, and P, which may also be considered as indicators of physiological status of the plant.
