K Damodara Chari Thank you for your query. The dose of biofertilizer depends on the following factors:
1. Formulation of the biofertilizer (Either it is Liquid or Carrier based/Solid). If that is liquid formulation doses should be in ml/ha. If it is solid then kg/ha etc. Thumb rule is confirmation of the coating of the seeds or the root dipping.
2. Type of crops: If the crop is agronomic crops (e.g. cereals/vegetables/other intensively grown crops) then apply as per dose given by Dr. Nikolay in early answer. If it is fruit tree then go for ring application with manures with twice of the referred doses for optimal result.
