Abstract
Field experiments were was conducted during the two successive seasons of 1996/1997 and 1997/1998 to investigate the effects of soil moisture (manifested as irrigation intervals) and nitrogen fertilizer on vegetative growth , yield nutrient uptake , concentTation of chlorophyll and carateniods and water consumptive use of lelluce and table beetsin El-Kanater Horticultural Research Station, Kaliobiya, Governorate . Lettuce and table beet plants were grown under different combinations of
3 soil moisture regimes : wet, n1cdiun1 and dry expressed as l
irrigation treatments having intervals of 8, 16 or 21 clays, respectively ; and 4 fertilization treatments (urea "U" 46 %N , ammonium sulphate AS 20% N , ammonium nitrate 33 %all at
40 kg N ; and no N.). Results may be sun11narizecl as follows
(means of the 2 seasons)
