In the present study, two parameters were studied firstly, the impact of various AM fungi on the growth and barbaloin content of Aloe vera and secondly the experimental design technique of Genichi Taguchi was devised specifically to optimize the effect of Am fungi, Azoobacter, rock phosphate and soil type for improvement of the growth and barbaloin content of Aloe vera plant.
However, parameters such as AM fungi, Azotobacter, rock phosphates and soil type have significant influence on the plant growth performance and barbaloin yield.
