Study the effect of phosphate-solubilizing bcteria on lentil yield and some soil properties in Deraa governorate-Syria

الملخص EN

A field experiment was conducted in order to study the effects of phosphate- solubilizing bacteria on lentil yield and some soil properties.

The experiment included eight treatments (control, 50% mineral fertilizers as per the recommendations of Ministry of Agriculture and Agrarian Reform (MAAR), 75% mineral fertilizers, 100% mineral fertilizers, phosphatesolubilizing bacteria, 50% mineral fertilizers + bacteria, 75% mineral fertilizers + bacteria, 100% mineral fertilizers + bacteria)] with three replications at Izraa Research station in Deraa in the growing seasons 2010 and 2011.

The soil was analyzed pefor-cultivation and upan harvesting.

N and P were estimated in both soil and plant.

Also, some plant parameters were identified in addition to the lentil yield Soil total N, available P, leaves N content and leaves P content were increased by inoculation with PSB in all treatments compared to those non-inoculated in the two seasons.

PSB significantly affected no.

of days to germination, no.

of days to flowering, no.

of days to maturity, percent germination and plant height.

In addition, lentil yield significantly increased in treatments amended with PSB in the two seasons compared to the control.

Moreover, treatment amended with 75% of chemical fertilizers and PSB (Biological yield was 4.25 ton/ha at season1 and 6.633 ton/ha at season2) was significantly better than that amended with full dose of chemical fertilizers (4.038, 6.383 ton/ha at the two season respectively).
