The origin of montmorillonite in vertisols from the Southern Serbian Pcinja District
This paper presents research results of the mineral composition of vertisols from Pcinja District in the southern part of the Republic of Serbia. Geological substrates were identified and positioned on the geological map of Serbia, soil profiles (no.1, 4 to 6) were opened and soil samples were taken in order to perform soil analysis. The mineral composition of soil samples was revealed by the X-ray powder...

Effects of different media on the transplantation of Huperzia serrata (Thunb.) Trev.
Wild Huperzia serrata was transplanted to moss, sand, corrosion soil, experimental garden soil, vermiculite mixed with perlite (1:1), and corrosion soil mixed with garden soil (1:1). The highest survival rate (90.0%) was observed in the moss medium, the second highest rate (53.3%) was detected in corrosion soil medium, and the lowest rate was found in garden soil medium. The physiological indices...

Contents of oxalic acid, nitrate and reduced nitrogen in different parts of beetroot (Beta vulgaris var. conditiva Alef.) at different rates of nitrogen fertilization
Beetroot has many positive effects on human health but can also accumulate considerable amounts of harmful nitrate and oxalate. A two-year open field trial was carried out to evaluate the influence of nitrogen fertilization on the content of different N compounds and oxalate in beetroot. Three nitrogen rates were applied: 0, 75 and 150 kg of N ha-1. Dry matter, oxalate, nitrate N and reduced N were determined in storage...

Marketing price transmission analysis in the Iranian rice market
The goal of this paper is to test whether changes in the marketing margin between the farm and the retail prices can result in an asymmetric relationship between the on farm and the retail prices in the rice market of Iran. By separating the transaction cost variation into two regimes, this paper utilizes a two-type TVECM with the error correction. The empirical results show that when the marketing margin is lower than...

Analysis of protein by colorimetric and computer color based intensity measurement method with anatomical sections of gram (Cicer arietinum) stem at three stages of growth
This research work is based on the establishment of new and easy techniques for the analysis of total proteins from anatomical sections. The proteins were measured from three different growth stages of stems of gram (Cicer arietinum). Firstly, protein was measured by colorimetric method and then analyzed from the cross sections of the same part of plant, sections were then stained with two different dyes and after that...
