Abstract

The test conducted on the site “Ouéllé 2C” at SUCAF Gabon, aims at determining the type and efficiency of the substrate that should be applied to get an optimal seedling and growth rate in sugarcane nursery. To do this, eighteen (18) treatments were formulated from five (5) amendments (bagasse, boiler ashes, scum, horse manure and sawdust) in various combinations to assess their effect on lifting and sugarcane growth. The control (T0) corresponds to the substrate composed of bagasse and scum. The variables measured were seedling (one month’s plantation) and growth through the height (cm), diameter (mm) and tilling on the 49th day after planting (DAP). The results obtained showed that the introduced amendments influenced positively the seedling rate because she was true to the 11th DAP, seven treatments were a strike rate of 100%. For the growth parameter, statistical analyzes revealed a significant effect (p-value <α) at the 5% level. The highest average values of: 68.38 ± 3.92 cm; 22.05 ± 0.27 mm and 34 ± 2.08 respectively tillers for height, diameter and tilling compared to control T0 (32.63 ± 0.75 cm; 13.25 ± 0.85 mm and 20 ± 1.5 tillers) were obtained DAP 49th, with the combinations of treatments based scum associated with horse manure and boiler ashes. It follows a treatment effect from these substrates. However T14 presented a depressive effect on the high setting. In light of the results obtained, we recommend the treatments T9, T16 and T18 for better lift and efficient growth of nursery sugarcane.
