abstract the cr(iii) and zn(ii) complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl)benzoic acid as ligand have been prepared by reacting cr(no3) and zn(no3)2 and ligand in cloroform. the cr and zn complexes with 2-((9,10-dihydro-1-hydroxy-9,10-dioxaanthracen-4-yloxy)carbonyl) were also prepared in chloroform and aceton solutions. the uv-visible and ft-ir spectra of...
in order to evaluate the effect of water deficit and different fertilizer levels on yield and some agro-morphological characteristics of moldavian balm, a split plot experiment was conducted in a randomized complete block design with three replications at the research farm of shahrekord university during 2013-2014 growing season. main factor was three levels of irrigation regimes including: 100...
In order to investigate the possibility of using organic fertilizers in tobacco floating nursery, an experiment was conducted at tobacco research institute of Urmia in 2010. The experiment was done as factorial trail based on randomized complete block design (CRBD) with four replications. The levels of first factor were disinfected poultry manure, disinfected pigeon manure, a complete fertilize...
BACKGROUND: Management of water deficit is a great factor to sustainable crop production, especially in arid and semi-arid regions. Vermicompost is an organic compound that is microbial active and rich in nutrients that results from the interaction of earthworms and microorganisms with organic matter decomposition. OBJECTIVES: This research was carried out to ...
introduction: in recent decades, excessive use of chemical fertilizers causes environmental problems such as water resource pollution and decrease in soil fertility. organic matters are excellent sources of plant-available nutrients and their addition to soil could maintain high microbial populations and activities. in crop studies, prabha et al. (2007) reported that there was excellent plant g...
BACKGROUND: Management of nutrients, especially nitrogen, in order to have economic production, maintain sustainable agriculture and provide food security, is considered to have an important priority. OBJECTIVES: Current study was conducted to evaluate effect of different level of nitrogen fertilizer and vermicompost on quantitative and qualitative traits of w...
In this research the effects of organic and chemical fertilizers on essential oil content and composition of lemon balm were investigated. This research was conducted in completely block randomized design with 4 replications in 2019 and 2020. Treatments were organic fertilizers (from source of horse, sheep, cow, hen and vermicompost) and complete chemical fertilizer of NPK (20-20-20). The most ...
