Silver birch (Betula pendula Roth) seedlings were grown individually in containers arranged in rows radiating from a central point (Nelder plot) at densities spanning the range from 207 to 891 plants m(-2). Height of one set of seedlings was measured at weekly intervals and additional seedlings were harvested each week for dry mass and leaf area measurements. Height and shoot:root dry mass rati...

This research was conducted to evaluate the effect of soil application of nitrogen (N) and iron (Fe) fertilizers on morphological traits and shoot mineral contents of bread wheat via factorial arrangement based on randomized complete block design with four replications. The factors included three level of nitrogen (100, 200 and 400 mg N kg-1 dry soil applied) as Ca(NO3)2 and three rate of Iron ...

Crop show morphological and physiological responses to microbial, physical or chemical factors which are known as elicitors. Chitosan is a natural biopolymer modified from chitin, which is the main structural component of squid pens, cell walls of some fungi and crab shells. Water stress is one of the most important abiotic stresses that affects plant physiological and morphological traits. In ...

BACKGROUND: Super absorbent polymers (SAP) by increasing the capacity of water storage and nutrition materials, reduction of wasting water and evaporation from the surface of soil improve crop production under water stress condition. Bio-fertilizers have the significant advantages to chemical fertilizers; for instance, they do not produce toxic and bacterial substances in the f...

BACKGROUND: Soil nutrition management is an important factor, which determines the plant growth. Soil fertility is determined by the presence or absence of nutrients i.e. macro and micronutrients, which are required in optimum level for crop. OBJECTIVES: Evaluate the effect different amount of nitrogen and phosphorus fertilizers in maize field under sugarcane ...

Objective: Chamomile is one of the commercial medicinal plants produced in Ethiopia. Besides, it is priority crop in national aromatic and medicinal plants research project in the country. As chamomile production affected by production techniques this activity was conducted to identify the effect of seed storage duration and seedling raising methods on its seedling establishmen...

in order to study compatibility of 30 white bean genotypes under karaj climate, an experiment was conducted based on randomized complete block design with four replications. evaluation and statistical analysis was performed for 18 important traits. analysis of variance results showed that there are significant differences between varieties for all traits. results of genotypes means comparison w...

which permits use and distribution in any medium, provided the original work is properly cited, the use is non-commercial and no modifications or adaptations are made. Abstract This experiment was conducted with the objective of evaluating the performance sage (Salvia officinalis L.) in different agroecology of Ethiopia for morpho-agronomic and chemical traits at Wondo genet, Hawassa, Qoqa and ...

Large plants are often more conspicuous and more attractive for associated animals than small plants, e.g. due to their wider range of resources. Therefore, plant size can positively affect species richness of associated animals, as shown for single groups of herbivores, but studies usually consider intraspecific size differences of plants in unstandardised environments. As comprehensive tests ...
