Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...
Increasing the current precision of nutrient management will need analytical tools that aid in collecting site specific data. A technology with potential is hyperspectral remote sensing. Modern, portable spectroradiometers permit reflectance data in the spectral region between 350 and 2500 nm to be collected quickly. With the limited sampling, handling, and processing required the technology al...
The percentage of population below age 6 years is an indirect indicator of the fertility level. In general, a large proportion of population under age 6 is symbolized with higher fertility norms. In other words, its higher proportion leads to young age-structure, i.e., a higher level of young dependency ratio. Therefore, lower the proportion of population below age 6, higher will be the index v...
consumption of organic manures such as vermicompost and spent mushroom compost in a system based on organic agriculture beside to maintenance soil health improvement and yield of medicinal plant spearmint. therefore, an completely randomized design experiment with four replication on spearmint (mentha spicata l )was conducted in horticultural department of mohaghegh ardabili university. experim...
this study purported to compare and contrast the use of self-mention and evidentials as two mtadiscourse features in opinion columns of persian and english newspapers. the theoretical basis of this study is the idea that metadiscourse features vary across cultural boundaries. for this purpose, 150 persian and 150 english opinion columns were collected based on three factors of topic, audience a...
A global study of relationships between leaf traits, climate and soil measures of nutrient fertility
Aim This first global quantification of the relationship between leaf traits and soil nutrient fertility reflects the trade-off between growth and nutrient conservation. The power of soils versus climate in predicting leaf trait values is assessed in bivariate and multivariate analyses and is compared with the distribution of growth forms (as a discrete classification of vegetation) across grad...
the present study was an attempt to determine the types of motivation and levels of foreign language learning anxiety among efl students studying at azad and state universities in kermanshah and to determine the relationship between these two factors and language proficiency and gender. to this end, the foreign language learning motivation scale, by deci and ryan )1985(, were administered to 12...
widespread changes in women’s roles in society, in turn, leads to their increasing participation in the social arena, therefore, by increasing women’s autonomy in different aspects of life, they are more likely to reach to higher positions and status than they were in earlier decades. this situation provides the context for changes in fertility ideals (fertility behavior, desires, and ideals) o...
Background: Due to its nutrient content, a variety of spoilage microorganisms can grow in bee pollen, especially when handling practices are not appropriate. So, this survey was designed to assess the physicochemical and microbiological properties of bee pollen collected from Bulgaria. Methods: In June 2014, 13 fresh and 19 dried bee pollen samples were collected from Bulgaria. Water activity ...
