| Abstract |
Drought resistance is the ability of a plant to maintain favorable water balance and turgidity when exposed to drought, thereby limiting or avoiding stress and its consequences. The aim of this research was to confirm the effect of organic amendments (OA) on plant resistance to water stress, and to get a better understanding of the processes involved in this resistance. In particular, we tried to assess whether the resistance to water stress induced by compost and vermicompost incorporated in the top layer (0-10 cm) had a positive effect on plant growth and root development. The soil was sieved (3 cm), poured into PVC column (60 cm high and 20 cm diameter) and repacked at a bulk density (ρ) of 1.3 g cm-3. We controlled 2 factors: (i) the type of organic amendments (OA) (compost (P) or vermicompost (V)) applied at a rate of 20 t ha-1; no OM was added for the control (C); (ii) the soil matric potential () during the plant development ( -100 hPa and -1,000 hPa, to produce non stressing conditions, and water stressing conditions, respectively). Chemical fertilizers were applied at identical rates in each treatment. Results indicate that OA application had an influence on plant resistance to water stress: it significantly increased plant height, above- and under-ground plant dry biomass, and corn yield as well as root dry biomass. However the positive impact of V was not found to be different from that of P. |
