PRODUCTIVITY OF SOME GEMMEIZA WHEAT CULTIVARS UNDER DIFFERENT SOWING DATES AND N FIRTILIZATION LEVELS

Abstract
Two field experiments were carried out in Belcas, Dakhalia Governorate,
Northern Delta, Egypt, during to winter seasons 2002/2003 and 2003/2004. The study
included three factors, viz., Gemmeiza (Gmz) cultivars (Gmz 3, Gmz 7 and Gmz 9),
three sowing dates (November 5th 15th and 25th) and three N levels (80, 100 and 120
kg N/fed). The results were as follows:
1- The CV Gmz 7, early sowing and highest N rate significantly surpassed the other
two treatments within each factor, with most studied traits
2- The cultivar Gmz 9 was the best one for producing straw yield/fed. Meanwhile, Gmz
3 successeded ¡n the production of heaviest grains.
3- The combinations which included Gmz 7, early sowing and higher N rate gave the
greatest values in the first as second order interaction, in most cases. The Gmz 9
replaced Gmz 7 ¡n the combination of producing sounded straw yield/fed.
4- Simple correlation within each pair of the studied traits was positive and significant
in most cases. .
