this exploratory study aimed to investigate a possible relationship between learners’ beliefs about language learning and one of their personality traits; that is,locus of control (loc). both variables, beliefs and locus of control, are assumed to influence the language learning process. the internal control index (ici) and the beliefs about language learning inventory (balli) were administered...
Black soldier fly (Hermetia illucens) larvae (BSFL) production is increasing, which will leaves substantial amounts of leftover excrement, called ‘frass’ that may be a beneficial organic fertilizer. In this study, sweetpotato (SP) (Ipomoea batatas) cuttings (‘slips’), were grown with BSFL frass as one-time top dressing at either 333.7g/m2 or 667.4g/m2, respectively, daily applications tea (225g...
iron deficiency or lime induced chlorosis is a common problem in calcareous soils. application of mineral iron fertilizer in these soils is not usually fully effective in curing iron deficiency as compared to organic chelates. cow manure and iron refuse (oxides), a by-product of iron melting factories were mixed in different properties of: 0, 5, 10, and 20 % v/v to make mixtures which of after ...
In order to investigate the effect of integrated management of phosphorus (P) fertilizer and phosphate solubilizing microorganisms on nutrients concentration and yield of two barley cultivars, a factorial greenhouse experiment was carried out based on randomized complete blocks design with three replications in 2011. Treatments consisted of two barley cultivars (Bahman and Fasih) and five types...

in order to evaluate the effects of different organic and chemical fertilizers on yield, yield components and seed oil content of sesame an experiment was conducted in a split plot layout based on randomized complete block design with four replications at research station, faculty of agriculture, ferdowsi university of mashhad in year 2006. four types of fertilizer, including chemical fertilize...
Excessive application of P fertilizers, use of the bicarbonated water sources for irrigation concomitant to a low level of organic matter have resulted in widespread iron deficiencies in crop plants in Iran. One of the strategies to overcome this problem is to select tolerant genotypes to iron deficiency (i.e. iron-use-efficient genotypes) or bred genotypes with high-micronutrient-uptake abili...
Nitrogen and and phosphorus are important components of plant nutrition. However inappropriate use of these nutrients can affect physiological aspects of plant. Therefore, in order to evaluate the response of some physiological parameters in purslane sucuulent plant to plant nutrition, an experiment was conducted as a RCBD with a split plot in time arrangement, which that nine levels of plant n...
this fertility experiment was carried out using split plots based on a randomized complete block design of three replications in 2006 at sari agricultural sciences and natural resources university. the aim of the experiment was to investigate some macronutrient and micronutrient accumulation in leaves of different soybean cultivars as influenced by some organic fertilizer types and levels. main...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...
