Abstract
The experiment was applied during spring 2020 at the farm of College of Agricultural Engineering Science Dohuk university to mingute the effect of various bio fertilizer levels on production nodules and some chemical and physical soil attributes after bio fertilizer soil application. The treatment consist of five rate of bio fertilizer (0,12,16,20 and 24 Kg ha-1) (Corabac® G), using randomize complete block design(RCBD) with three replications using local variety of chickpea, The results exhibited that the bio fertilizer levels were highly significant effect on number of nodules, plant seed yield, first pod height and number of pods plant-1.The level 24 Kg ha-1 gave highest values for nodules plant (73) by increasing 48% compare with control, the maximum yield value 610 Kg ha-1 was recorded by the same levels and also the results showed the highest values for plant height (55 cm), number of main branches plant-1 (4.0), secondary branches 8.33 and number of pods plant-1 25. The application of bio fertilizer decreased pH from (7.94 to 7.5), EC from (0.55 to 0.522 ds.m-1) while increase K from (0.17 to 0.21 mmolc.l-1) and organic matter from (17.1 to 19.4 gm.kg-1). this results indicated that the bio fertilizer application to soil remarked positively from plant development and attributes to change in some physical and chemical properties of soil.
