| Abstract | ||
| A field experiment was conducted during the growing season of 2016 -20117, in Al-Muthanna province, to study N P K availability in soil, number and weight of root nodules and yield broad bean by adding HA and FA acid to soil. A simple experiment designed by using RCBD method included adding HA and FA acid (0, 5 ,10 ,15ml ha-1). Significant increases in N P K availabilities were accompainied with H2 treatment for N and K 32.76, 204ml.kg-1 sequentially. H3 gave the highest rate of N.P.K. availabilities 28.62 ,14.30 , 155 ml kg-1 s, respectively. H3 gave highest nodule fresh weights 616.00 mg. Besides the highest rate of plant yield 169g, and 134.8g, as compared to control. | ||
