Abstract
An experiment was conducted according to randomized complete block design (RCBD). In loamy sand soil in pot at 9 kg. to study the effect of four isolates for two types of bacteria Azotobacter ( A.chroococcum , A.vinelandii) and four concentrations of water S0, S1, S2, S3 (0,5,7.5,10) dS m-1 on the growth and grain yield of wheat plants (Triticum aestevium L .) the Culture IPA-99. The results showed that there were significant increase in all vegetative growth characteristics plant height, leave area, content of chlorophyll, dry weight of vegetative and root system and grain yield compared without inoculation irrespective with application of salinity. The isolate A14 from A.vinelandii gave higher number of plant height, leave area, contant of chlorophyll, dry weight of shoot and root system and grain yield. The increase of salinity water caused significant decrease in the average of all studied characteristics. Inoculation of pots with A.chroococcum , A.vinelandii caused significantly increased in plant height, leave area, content of chlorophyll ,dry weight of vegetative and root system and grain yield for all of salt levels compared withnot inoculation. The highest values of plant height and leaf area and the content of chlorophyll a, b and the total of chlorophyll had been obtained of the isolation A14 A.vinelandii bacteria isolated from soil salinity.
