Abstract:
The present investigation entitled “Effect of AM fungi on growth of custard apple (Annona squamosa L.) Seedlings” was carried out during December 2021 to May 2022 at center of excellence for protected cultivation (CEPC), Dr. Y.S.R Horticultural University, Venkataramannagudem, West Godavari. The experiment was laid out in Completely Randomized Design (CRD) with four treatments Glomus fasiculatum @ 3 g, Glomus leptotichum @ 3 g, Glomus fasiculatum @ 1.5 g + Glomus leptotichum @ 1.5 g, non mycorrhizal) and five replication.The results revealed that the application of Glomus fasiculatum @ 1.5 g+ Glomus leptotichum @ 1.5 g resulted in significant improvement of seedling height (19.27, 27.61, 38.98, 45.67 and 53.17 cm), number of leaves per seedling (11.88, 16.38, 19.23, 22.34 and 25.12), stem diameter (3.65, 4.42, 4.85, 5.45 and 6.13 mm) and total chlorophyll content (8.91, 9.56, 10.74, 11.00 and 12.16 mg/g^-1) at 70, 90, 110, 130, 150 days after sowing.
