a trial study was carried out to assess the influence of the plant residue management in conjuction with application of different nitrogen sources on wheat yield and components, at the agricultural faculty of shahidchamran university of ahvaz during 2011-2012.the experimental design was splitplot at randomized completed block design arrangement. the main plot were different wheat residue manage...

understanding of relations and interactions between ecosystem’s components and plants is one of the main conditions for sustainable production of medicinal plants. to study the effect of simultaneous application of organic and biological fertilizers on yield and yield components of zucchini squash, a split plot arrangement of factors based on randomized complete block design with tree replicati...

The Greek coastal waters are subjected to harmful algal bloom (HAB) phenomena due to the occurrence of species characterized as toxic (TX), potentially toxic (PT), and non-toxic, high biomass (HB) producers causing harm at multiple levels. The total number of (TX), (PT) and (HB) algae reported in this work are 61, but only 16 species have been associated with the occurrence of important HABs ca...

To survey the effects of chemical and biological phosphorus on the yield and essential oil of Satureja hortensis L. as an important medicinal plant, factorial experiment was conducted based on randomized complete block design with three replicates at Research Station of Faculty of Agriculture, Urmia University in 2011. The treatments were chemical phosphorus fertilizer with four levels (0, 50, ...

The goal of this paper is to provide an overview of an emerging new framework for understanding early phonetic development – The Natural Referent Vowel (NRV) framework. The initial support for this framework was the finding that directional asymmetries occur often in infant vowel discrimination. The asymmetries point to an underlying perceptual bias favoring vowels that fall closer to the perip...

in order to examine the effects of biological and chemical fertilizers with the use of salicylic acid on the agronomic characteristics of corn as a factorial experiment in randomized complete block design with three replications at the agricultural research station in 2011 was boroujerd. factors examined included three levels of phosphorus fertilizer (0, 100 and 150 kg ha), two levels of biolog...
