Abstract
A field experiment was conducted in agricultural second research station, Agric. College, Al- Muthanna Univ., Iraq, during 2016 – 2017 growing season to determine the effect clover inoculation with bacterial, and different mixture ratios of oats Avena sativa L. (25{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, 50{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, 75{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} and 100{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}) with amount of Trifolium alexandrinum L. seeds (40kg. h-1)] on growth, green forage yield, for five cutting. Bacterial inoculation treatment recorded the highest 5th cutting in plant nitrogen content 0.44{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, 4th cutting in branch numbers 2265 branch.m-2. Clover alone gave 0.97{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} in the 2nd cutting. Clover and Oats mixture treatment was superior over others in plant nitrogen contents 0.75{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, in 2nd cutting, The highest forage fresh and dry weights in 2nd cutting 80.30 and 10.73 ton ha-1, respectively, were confined to mixture treatment of 75{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} Otas + Clover. 50{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} Oats + Clover x bacteria inoculated mixture showed the highest plant nitrogen content0.66{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d}, in 4th cutting. Clover only x bacterial inoculation gave the highest yield of green forage in 4th cutting 99.70ton ha-1. 75{8aa0d92a9d700de00931fb59e75e46e902b43698544c97f28f7bec3700555d1d} oats +Clover x bacterial inoculation revealed the highest dry yield weight in 4th cutting 12.17ton ha-1 .
