Abstract: 
The effect of prior soil amendment with different N sources at 50 mg N (kg soil)(-1) on nodulation and N-2 fixation of faba bean (Vicia faba L. cv. Troy) using wheat (Triticum aestivum L. cv. Star) as reference crop was assessed in a pot experiment. Four treatments viz legume manure (LEGM) as clover shoots, cereal manure (CEREM) as barley straw, N fertilizer (FERT-N) as Ca(NO3)(2), and no-manure control (NOMAN) were investigated consecutively at 45, 70, and 90 days after sowing (DAS). Faba bean nodulated profusely, with an increase on average from 629 nodules per pot at 45 DAS to nearly 2.3- and 3.3-fold at 70 and 90 DAS, respectively. Low nodule numbers and nodule dry matter occurred under FERT-N and CEREM,, whereas high values were found for NOMAN and LEGM. Soil amendment affected percent N-2 fixation in relation to N source and plant Age. Highest percent N-2 fixation ( greater than or equal to 90 %) was found under the lowest N-supplying amendments, no-manure, and cereal manure, respectively. FERT-N depressed N-2 fixation particularly at 45 DAS when N-2 fixation was reduced to as low as 23 %. The rise in, N-2 fixation thereafter suggests that faba bean adjusted after depletion of mineral. N in the soil. N-2 fixation was also decreased after cereal straw application, even though N N concentration in faba bean plants was high. The results indicate that plant residues, both with high and low N concentration, applied to soil to raise its fertility May interfere with N-2 fixation of faba bean.
