Four  field  experiments  were conducted at EL- Minia Governorate in new reclaimed sandy (samalout District , west bank of the Nile ) and Mallawi Agricultural   Research   station ,   during  the   two  successive  seasons in  1999/ 2000 and 2000 / 2001   to study the effect of biofertilizer on barley productivity under new reclaimed sandy  and silty clay loam soils . The studied characters were number of spikes / m²  , plant height in cm , spike length in cm , number of kernels / spike , weight of  kernels / spike in gm , 1000 - kernels weight in gm , grain yield in ardab / fed and straw yield in ton / fed  Results showed that the  application of biofertilizer with the  recommended doses of nitrogen and phosphate fertilizers under new reclaimed sandy and Silty clay soils in middle Egypt increased significantly the most characters of barley crop compared with the control  without the application of biofertilizer. Also application of biofertilizer significantly increased plant height , number of spikes / m2 , grain yield (ardab / fed ) and straw yield ( ton / fed ) in both seasons compared with the treatment of control without application of  biofertilizer. while spike length and number of kernels / spike were significantly increased in  the second season and the first season . respectively , The increases of spikes/ m²  withapplication of  biofertilizer compared with control in new reclaimed sandy soil were 40.90 % in the first season  and 25.58 % in the second one while in silty clay  soils the percentage of increases reached  15.32%  in the first season and 15.30 % in the second one However  the average increase percentages in new reclaimed sandy and silty clay loam soils  were 25.52 % in the first season and 20.02% in the second one The increases in grain yield due to  using biofertilizer compared with control in sandy soil were 47.36 % in the first season and 26.49% in the second one but in silty clay loam the increase percentages were 19.50 in the first season and 20.18 in the second one while the mean  percentages in sandy and silty clay were 33.45% and 23.39% in the first and the second seasons respectively . The increases of straw  yield as a result of using biofertilizer in sandy soil  were 61.79% in the first season and 33.33% in the second one while in silty clay loam  increase the percentages were 8.58% in the first season and 16.79% in the second one. However the average  increase percentages in sandy and silty clay loam were : 28.25 % in the first season and 23.69% in the second one . The percentages of increases due to using biofertilizer with nitrogen and phosphate recommend on number of spikes  / m2  , grain and straw yields obtained more amount in new reclaimed sandy than the silty clay . Thus , it can be concluded that application of biofertilizer with the recommended doses of nitrogen and phosphate fertilizers gave  the maximum productivity of barley crop in new sandy more amount than silty clay loam  under EL-Minia  governorate conditions .
