Grow complex is a common soil inhabitant of tropics. It is an associative symbiotic nitrogen fixing bacterium. The organisms form associative symbiosis with many plants particularly with those having the C4 - dicarboxyliac pathway of photosynthesis. It fixes nitrogen in the roots of many non-leguminous crops like cereals, millets, forage crops and vegetables, etc. Besides fixing nitrogen,it also produces growth promoting substances/hormones such as indole acetic acid, gibberellins, pantothenic acid, thiamine and niacin required for vegetativegrowth of the plants. Moreover, it promotes root proliferation and improves the plant growth and yield. Grow Complex increases the rootlet density and root branching resulting in the increased uptake of mineral and water.
