to evaluate effected of supplemental irrigation and seed priming on yield and some quantity and quality characteristics of vetch (vicia dasycarpa) rainfed maragheh cultivar, an experiment was carried out at the research farm of faculty agriculture of urmia university, west azarbaijan province, iran, during 2011. the experimental design was split-plot, laid out in randomized complete block with...
the present study aimed to investigate representation of discourse markers and metadiscourse markers in conversations and readings of general elt coursebook series used in the language centers of iran. to this aim, four elt coursebooks popularly taught in language centers of this country were analyzed based on fung and carter’s (2007) framework regarding discourse markers and hyland’s (2005) fr...
The litter carbon (C) pool of a single litter cohort in an agroecosystem is the difference between net primary productivity and decomposition and comprises 1113% of the total C pool (litter and soil 0-15 cm depth) post-harvest. This litter-C pool is highly dynamic and up to 50% can be decomposed in the first 12 months of decomposition. Thus, understanding litter-C dynamics is key in understandi...
In order to evaluate the effect of drought stress and nitrogen (N) fertilizer levels on yield, yield components and protein content of two barley cultivars (Yousef: six-rowed and Nimrouz: two-rowed), field experiments were conducted at the Fars Agricultural Research Center – Zarghan Station, during 2010-11 and 2011-12 growing seasons. The experiment was carried out as split-split plot based on ...
Eucalyptus plantations occupy almost 20 million ha worldwide and exceed 3.7 million ha in Brazil alone. Improved genetics and silviculture have led to as much as a three-fold increase in productivity in Eucalyptus plantations in Brazil and the large land area occupied by these highly productive ecosystems raises concern over their effect on local water supplies. As part of the Brazil Potential ...
there are about two of millions rainfed fig trees in estahban. this main location of iran rainfed production is faced with death and destruction as a result of recent droughts and since rain is the only source of water supplied to the trees in rain-fed conditions. the effects of different levels of water stress on the plants stomata and guard cell response were investigated throughout this work...
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
A field experiment was carried out during 2009-11 on a sandy loam soil of IARI, New Delhi on wheat with four levels of irrigation (rainfed, irrigations to replenish 30, 60 and 100% moisture deficit from field capacity) as main plot factors and four levels of nitrogen (0, 30, 60 and 120 kg N/ha) as subplot factors in a split plot design. The soil moisture storage in the profile showed inverse re...
Water deficit is an important factor limiting crop growth all over the world. In order to evaluate genetic variation, heritability and the interrelationship between agronomic traits, twenty chickpea genotypes were cultivated in two separated randomized complete block experiments with three replications under normal irrigated and rainfed conditions. The experiments were carried out at the Agricu...
