Dear RG Colleagues,
I am trying to study the effect of a biofertilizer and I am confuse about the experimental design.
So I have :
3 plant species and only one factor "Biofertilzer" and my area is 400 m2.
How should I proceed and How many replicates (plants) should be used at the sampling stage ?
Thank for your contributiom

Thank you Dear Janerson José Coêlho and Vikki Wong for your answers.
I am working with only one concentration of a biofertilizer.
So, as you suggest, I will choose a randomized complete block design with 4 replicates (Blocks) in my 400 m2 and for the 3 studied species. It will be 16 m2 for each block.
If you allow my next question, at the stage of harvesting, how many plants should be sampled and how in each block?
A esearch paper with a clear figure of the experimental design will be a good help.
Thank you again for your attention and considertion.

Randomized complete block design (RCBD) or simply block design as mentioned above can be used to eliminate effects from any factors that may cause variation within the 400m2 area that you are using. As long as factors such as planting density, biofertilizer application method and interval, drainage or watering system if applicable are consistent and your blocking method is correct, then it should be fine.
