Glycine Betaine (GB) solution at concentration 0.08 molar was used for soaking grains of bread wheat variety (Sham _6_) before sowing at these periods of time (0,6,12,18,24 hours) to evaluate its effect on plant height , number of spikes/plant, weight of spikes / plant, weight of 100 grains, grain yield / plant, and biological yield. The results indicated that there were significant and desirable decrease in plant height and significant desirable increase was observed for 6 hours treatment for all traits. High significant differences were detected for genetic, environmental and phenotypic variances for all characters. The environmental variances was more than genetic one. The broad senses heritability was medium for plant height , number of spikes /plant, weight of spikes /plant, weight of 100 grains, grains yield /plant and biological yield.

Experimental studies were conducted in a wire house .It includes evaluating the effect of soil remnant which had been planted with two cultivar of wheat(Al-ize and Talafar-3-) when mixed previously with remnant of fenugreek plant with both ,shoots and roots parts and with two stage s of growth (seedlings and mature) on the growth of fenugreek plants (cultivar Indian) All data were subjected to statistical analysis. The results showed superiority of fenugreek plants grown in soil cultivar wheat Al – ize that was planted on soil previously had a groining wheat class Talafar -3- in most of the physiological parameters of growth (leaf area duration (LAD), Biomass duration (BMD), Leaf area ratio (LAR), Relative water content and grain yield. On the other hand, fenugreek plants grown in soil without fenugreek residue has overtaken in physiological parameters (Leaf area duration (LAD), relative water content grain yield) compared with the soil residues . which did not show the impact of the two phases of growth in most of the characteristics of growth, except for high values of each of leaf area duration (LAD) in seedling stage residue, and (NAR) in mature stage residue.
