This Research aimed to study on effect of foliar spraying with zinc (as zinc sulphate), nitrogen (as urea) and iron (as sulphate and chelated Fe) on growth parameters, quality of fruit, flower characteristics, chemical constituents and nutrients content of leaves on grapevine. Applied nutrients were zinc sulphate (Zn) of 0.0 and 1.5gl-1 and urea (N) at 0.0 and 5 gl-1 and Fe (1) control (low Fe)...

On an intensively prepared site, a complete fertilizer applied at planting, and control of herbaceous and woody plants for the first 4 years, increased Pinus taeda L. volume at age 5 to 25.9 m3/ha compared t o 11.8 m3/ha without the...

BACKGROUND The aim of this study was to evaluate the effects of nitroxin biofertilizer and chemical fertilizer on the growth, yield, and essential oil composition of dill. The experiment was conducted under field condition in randomized complete block design with three replications and two factors. RESULTS The first factor was the concentrations of nitroxin biofertilizer (0%, 50%, and 100%) o...

objective(s) previous studies have demonstrated that the nitric oxide (no) dependent death of murine peritoneal macrophages activated in vitro with ifn-g and lps is mediated through apoptosis. in the present study, we investigated the synergistic effect of lps, ifn-g and iron on no production and apoptosis. materials and methods after determination of iron cytotoxicity, the peritoneal macrophag...

Nutrients in the form of fertilizers and/or other additives such as amino acids, dramatically influence plant development and growth, plant nutrient composition and the level of soil pollution. Moreover, the treatment of soil microbiota is emerging as a new strategy in plant breeding to achieve desirable traits. Thus, integrated study of fertilizer application and soil microbiota might lead to ...

abstract to evaluate the effect of different sources of p fertilizer on grain yield and yield components of two barely varieties, this experiment was conducted in research farm, college of agriculture, university of tehran in 2010. the experimental treatments were arranged as factorial based on randomized complete block design with three replications. the treatments consisted of two barely vari...
