Sunflower (Helianthus annuus L.) can have an important role in vegetable oil production. Also, appropriate soil fertility is necessary to obtaine higher seed yield and quality of the crop. This experiment was conducted to investigate the effect of fertilizer treatments of macro and micronutrients on seed yield and other agronomic traits in sunflower. The effects of thirteen fertilizer treatemts...

background and purpose: according to fao's report, lentil yield in iran is much lower than average yield in the world. this is due to low quality seedling production, low germination and emergence capacity, biotic and abiotic stresses and poor seedling establishment which was forced to looking for a way to enhance these components. seed priming is one of the strategy for increasing the rat...
Certain microorganisms in soil have phosphate solubilizing ability. Phosphorus has an important role in plant nutrition and N2 fixation in legumes. The interactive effect of three phosphate solubilizing bacteria (PSB) and Bradyrhizobium japonicum on yield and N, P, K uptake and nodulation of soybean root (Glycin max L. CV. Harcor) was studied under greenhouse conditions. In greenhouse experimen...
Inclusion of cover crops in crop rotations has several benefits such as supplying nitrogen for the next crop. To investigate the effect of cover crops and different levels of nitrogen fertilizer on tuber yield, yield components, and different nitrogen efficiency indices of potato, a filed experiment was conducted as split plots arrangements in randomized complete block design with three replica...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
The experiment was conducted to assess the impactofZn and B application on sunflower growth, yield oil content in sub-tropical condition. laid out randomized complete block design (RCBD) with twelve treatmentsand replicated thrice. treatments comprised viz; T1: Without fertilizers (absolute control), T2: RDF (N80P40K40), T3: N80P40K40Zn0.5%, T4: N80P40K40Zn4, T5: N80P40K40B0.2%, T6: N80P40K40B2...
This descriptive cross-sectional study determined the prevalence and sources of verbal and physical workplace abuse in the last 6 months, the nurses' reactions to abuse, and their opinions about it. Datawere collected by questionnaire from 447 nurses working in various departments in 3 hospitals in Amman. The prevalence of verbal and physical abuse was 37.1% and 18.3% respectively. Younger, les...
The needs of the dysphasic patient with a stroke, in whom the effect of physical damage is so often intensified by loss of morale, are well recognised. Both the numbers who survive and the long periods for which support is needed create a problem that is unlikely to be relieved without help from the community. A pilot scheme using untrained volunteers working within a responsible organisation a...
