Abstract
Effects of application of different nitrogen sources i.e., ammonium nitrate (AN) with different rates of nitrogen ( 0, 20, 30 and 40 kg N fed.-1 ) and anhydrous ammonia (AA) as well as biofertilizer (Rhizobium radiobacter sp.) as PGPR strain either alone or in a combination with AN rates on faba bean (Vicia faba L., cv. Nubaria 1) were studied on a loamy sand soil at the Experimental Farm of Ismailia Agriculture Research Station, Egypt during the two successive winter seasons of 2013/2014 and 2014/2015. The results could be summarized as follow: Inoculation with (Rhizobium radiobacter sp.) + 40 kg N fed.-1 as ammonium nitrate led to highest increases for number of pod plant-1, seed yield, pod yield and seed Mn content , inoculation with (Rhizobium radiobacter sp.) + 30 kg N fed.-1 as ammonium nitrate led to increase for P and K contents in seeds. Similar increments for 100-seed weight, protein content along with N, Fe and Zn contents of grain were recorded with anhydrous ammonia at rate of 40 kg N fed.-1 as ammonium nitrate. The uptake of macro and micronutrients significantly increased in combined treatment of (bio+N40) . In soil after harvest, inoculation with (Rhizobium radiobacter sp.) + 40 kg N fed.-1 as ammonium nitrate led to highest decreases of both soil pH and EC but increases of available P, K, Fe and Zn contents. The highest values of available N was recorded due to inoculation with (Rhizobium radiobacter sp.) + 30 kg N fed.-1 as ammonium nitrate , available Mn increased with anhydrous ammonia at the rate of 40 kg N fed.-1 as ammonium nitrate.
