Abstract:
Seed vigour is an important determinant on successful plant establishment in the field which determines the crop performance and the final yield. This study investigated the effect of biopriming with a commercial biofilm biofertilizer (Biofilm-R) on seed germination and seedling vigour of two vegetable varieties, Solanum lycopersicum (tomato) and Capsicum annuum (bell pepper). The seed germination parameters were determined using the Ragdoll method and growth performance was tested in soil in a pot trial six weeks after sowing. The means of the control and the bioprimed treatment of each parameter were compared using the T Test (p≤0.05). Biopriming improved germination parameters of both varieties ranging from 6 - 78% in bell pepper and 133 -171% in tomato. Seedling parameters too were enhanced by biopriming ranging from 53 - 402% in bell pepper and 35 – 285% in tomato. The results indicate that the Biofilm-R is a potential
biopriming agent and it has the potential to continue to support plant growth of both varieties. However, further investigations under field conditions are needed.
