| Popis: | The research in the period 2010-2011, within the Ezareni Farm from Iasi, were focused on the influence of inoculation, fertilization and harvesting growth stage on the leaf/shoot ratio and dry matter (DM) yield, at alfalfa ( medicago sativa L.) in the second year after sowing at the first harvest. The results indicated that the interaction between inoculation, fertilization and harvesting growth stage determined increases of yield in the range of 23-110%. The control plot where fertilization was not applied, without inoculation, which was harvested at early bud registered the lowest yield, 3.21 t/ha D.M., and the biggest yield (6.72 t/ha) was registered at the plot with inoculation, fertilized with N 75 P 50, harvested at 10% blooming. The leaves/shoots ratio registered differences in the range of +11% to -42%, accordingly to the interaction between the inoculation, fertilization and harvesting growth stage. The highest leaves/shoots ratio, 0.64% was observed at the plot with inoculation, unfertilized, harvested late bloom, and the lowest leaves/shoots ratio (0.33) was observed at the plot without inoculation, fertilized with N 75 P 50 harvested at full bloom. |
