The experiment was planted in the January 24, 2006 AD.
Here are the top search results in this season:
1 - Aswan give the product the highest productivity of the floral cups, where the productivity of 404.82 kg / ha dry floral cups, followed by Siwa where he produced 331.55 kg / ha dry floral cups.
2) product items, Siwa was the highest in the concentration of vitamin "C" in floral cups, where he was 67.427 mg / 100 g, followed by Aswan concentration of 63.075 mg / 100 gm.
) Category items, Siwa was less in the concentration of calcium oxalate floral trophies, and contains 1.846 mg / 100 g, followed by Aswan concentration 2.228 mg / 100 gm.
4) varieties Sudan Sudan-1 and -2 were concentrated in fewer varieties of vitamin "C" and higher categories in the concentration of calcium oxalate in the floral cups.
5) give the rate of nitrogen fertilization 368 kg N / ha, the highest yield of cups floral dry, where the productivity 386.93 kg cups floral dry / ha and even with the morally average 276 kg N / ha, the productivity of 363.91 kg glasses vase / ha followed by average 184 kg N / ha and zero nitrogen / ha.
6) the concentration of vitamin "C" Top morally under the influence of fertilization rate of 276 368 kg N / ha, as they were 66.45 0.62 mg / 100 g, respectively.
7) did not show significant differences between the four nitrogen fertilization rates in effect on the concentration of calcium oxalate in the floral cups. |
