in order to study the effect of foliar zinc spraying on photosynthetic pigments and yield of chickpea under water stress conditions, a factorial experiment carried out based on randomized completely block design (rcbd) with three replications in university of mohaghegh ardabili agricultural research station in 2012. the treatments consisted of three levels of irrigation (irrigated at planting, ...

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)...

background: biosynthesis and metabolism of phytochemicals in medicinal and aromatic plants are vigorously affected by different abiotic elicitors including chemicals. objective: this experiment was designed to investigate the effects of three levels of copper sulfate (cu: 0, 5, 25 mg kg-1) and zinc sulfate (zn: 0, 10, 50 mg kg-1) and their combinations on yield, chemical compositions of essenti...

The present study aims to assess the effect of Thiobacillus and sulfur on morphological and biochemical properties of medicinal pumpkinproperties under deficit irrigation based on a split-plot design. For this purpose, water stress was applied as a main factor in three levels (control, no irrigation in flowering stage, no irrigation in fruiting), and Thiobacillus and sulfur fertilizers as sub-p...

high-density planting system is one of the effective methods for improving production and profitability of tree orchards. in this research, the effects of four planting densities (1904, 2666, 3137 and 4800 tree/ha) on annual shoot growth, tree yield, physicochemical properties of fruit and leaf mineral contents of apple (malus domestica borkh cv ‘granny smith’treegrafted on m26 clonal rootstock...

To study the effect of Zn and B as foliar spray on growth and yield of sweet orange, cv. Blood red at Dargai, Malakand Agency, Pakistan during 2006 and 2007. The micronutrients zinc (Zn) in the form of zinc sulphate (ZnSo4.7H2O) as zinc source at the rate of 0.5 % and 1.0 % and boron (B) in the form of boric acid (H3BO3) at the rate of 0.02 % and 0.04 % were applied as foliar spray at three dif...
