Abstract
ABSTRACT
Four field experiments were carried out during 1998, 1999 and 2000 summer seasons. The first and second experiments were conducted at the Experimental Station of the Faculty of Agriculture, Cairo University, Domo, El-Fayoum Govemorate in 1998 season. The third and fourth experiments were conducted at the High Institute of Agriculture Cooperation Farm, Wadi El-Faregh, Cairo-Alexandria desert road, 62
Kilometers away from Cairo in 1999 and 2000 seasons. The study aimed
to investigate the effect of some abiotic stresses on vegetative growth characteristics of soybean (Glycine max (L.) Merr.) throughout growing ten soybean genotypes under sandy and saline soils conditions and water stress by skipping one day of drip irrigation under sandy soil conditions from flowering stage up to harvest. As a result of salinity, plant height,
number of green leaves/plant, number of branches/plant and leaf fresh
weight decreased considerably compared to sandy soil condition over all studied genotypes with a reduction of 54.6, 67.7, 54.1 and 75.4 %, respectively. Highly significant differences between soybean genotypes were obtained under both sandy and saline soil for all vegetative growth
• characteristics except for plant height under sandy soil condition in 1998 season.
