Abstract: In the present system of agriculture, chemical fertilizers are used indiscriminately throughout the world. However, the cost of these fertilizers has been increasing, exponentially and at the same time polluting soil and ground water. In this scenario, the use of eco-friendly bio fertilizers, particularly arbuscular mycorrhizae (AM) is one of the promising alternatives to increase the productivity of agricultural crops. An attempt was made to study the chemical and enzymatic parameters of soil with the occurrence and prevalence of AM fungi in different agricultural crops of Andhra Pradesh. Root and rhizosphere soils of four major crops such as cotton, sugarcane, rice and black gram were collected at different growth stages of the crops and assayed for AM fungi colonization and spore density. Also, the soil chemical and enzymatic parameters such as organic carbon, alkaline phosphatase, glomalin were assayed from these soil samples. Our results showed that the four crop roots colonized by AM fungi. The percent root colonization by AM fungi was maximum in cotton (82.3%) followed by black gram (70%) and rice (35.6%). Whereas the spore number was highest in black gram (42/100g of soil) followed by cotton (39.2/100g of soil) and rice (26.6/100 g of soil). The chemical and enzymatic parameters measured such as organic carbon was maximum in rice (0.79%), followed by sugarcane and cotton (0.73%). Alkaline phosphatase was highest in sugarcane (32.73 p-nitro phenol μg/g wt. of soil/hour) followed by black gram (23.93 p-nitro phenol μg/g wt. of soil/hour) and glomalin was highest in sugarcane (7.96 mg/g) followed by black gram (5.49 mg/g). Our results showed that there was a positive correlation between chemical and enzymatic factors measured with the AM fungi prevalence in the roots and rhizosphere soils of the crops evaluated.
