Nitrogen Metabolism in Scenedesmus as Affected by Environmental Changes.

Nitrogen Metabolism in Scenedesmus as Affected by Environmental Changes.

In recent years investigations into the physiology of green algae have been stimulated by a recognition of their possible commercial use (6) in addition to their common acceptance as research tools for certain fundamental problems. These physiological studies have shown that green algae have a high nitrogen content. A correspondingly high protein content has been inferred (28). Relatively littl...

Changes in weed seed banks and the potato yield as affected by different amounts of nitrogen and crop residue

In order to evaluate the impact of crop residues (zero, 25 and 50%) and nitrogen (zero, 125 and 250 kg ha) on weed seed bank and potato yield, two-years research was conducted as a split plot arranged in randomized complete block design in Rozveh Agriculture Research Station, Freidan-Esfahan. Numbers of weed species in seed bank, aboveground, and both seed bank and aboveground were 1, 2 and...
