There have been several questions and arguments for the usage of guar gum in food related applications. Ten years ago, there had been concerns on the level of pesticides usage in guar gum production. This concern has however been addressed and closed.
The guar crop is grown from seeds, where one hectare requires at least 30 kilograms of seeds. It is done at a spacing of 50 cm between rows and 25 cm between plants. Sowing is done in ridges approximately 3 cm deep. Fertilizer application is required during the growing period. In production, one hectare can produce 5 tons of seed and 50 tones of bio mass. It is drought and salinity tolerant.
