Guar plant develops, nodules on its roots, in which a special kind of bacteria live and convert the free nitrogen of the atmosphere into a form of fertilizer which is absorbed by the roots of the plant.
This symbiotic relation of the bacteria and root nodules is useful in saving cost of nitrogenous fertilizers. Therefore, before sowing the seeds are inoculated with these bacteria so that their population increases in the soil, with the growth of the plant. This is done by preparing a 10% sugar or gur solution in boiling water. This sugar solution is allowed to cool.
On cooling 3 -4 packets of guar bacterial culture are mixed with solution to make a thin paste. This paste is coated over to the seed. Seed is dried under shade for 30 -40 minutes before sowing.
what is the bacteria strain ?
