Abstract
Field experiments were carried out at Sids Agricultural Research Station, Agric. Res. Cen., Bani- Suef Governorate, during the three successive seasons 1995/96, 1996/97 and 1997/98.
The experiments aimed to investigate the performance of 6 new long spike wheat varieties under different N levels. The experiments were executed in clay fertile soils.
The evaluated varieties were: Sids 1 (a commercial cultivar grown as a check variety ), and the long spike varieties : Sids 4, Sids
5, Sids 6, Sids 7, Sids 8, and Sids 9. The nitrogen levels were : 0, 30,
60, 90, 120 and 150 kg/ fad. TheN carrier was ammonium nitrate
(33.5% N).
A split plot design with four replications was used. N levels were distributed randomly in the main plots and varieties occupied the sub plots. The sub plot area was 8.4 I m2 • Phosphorus fertilizer was applied as calcium superphosphate (15.5 P205) at a rate of 150 kg/ fad. Potassium sulphate (48% K20) was also applied at 50 kg/ fad.
Sowing date was 26 th, 20 th and 17 th of November in the first, second and third season, respectively. Harvesting was followed on
8 th, 4th and 5 th of May, respectively. The normal cultural practices as
recommended for the region were followed.
The results of the combined analysis of the three seasons average could be summarized as follows:
