Abstract

The present investigation was carried out on 22-year-old aonla (Emblica officinalis Gaertn.; variety NA-7) trees during the years 2023 and 2024 at Kalyanpur Nursery, Department of Fruit Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur. The design of the experiment was randomized block design with three replications involving ten treatment combinations formed by applications of Azotobacter, PSB, Amritpani, Jeevamrit and Panchagavya. Significant improvements were recorded on the growth, flowering and yield traits, with T9 (Azotobactor(5 g/tree) + PSB (50 g/tree + Amritpani (10  %) + Panchagavya (5  %) consistently outperforming others. Among the evaluated treatments, T9 (Azotobactor(5 g/tree) + PSB (50 g/tree +Amritpani (10  %) + Panchagavya (5  %)  exhibited the highest performance in key growth traits, recording maximum plant height (11.04, 11.42 & 11.23 m), stem girth (72.25, 74.56, 73.41 cm), plant spread in the north-south direction (7.58, 7.64, 7.61 m), plant spread in the east-west direction (7.69, 7.74, 7.72 m) and number of shoots per tree (10.54, 10.66, 10.60) during 2023, 2024 and pooled, respectively. Similarly, T9 also recorded the highest values for flowering and yield attributes such as total number of flowers per meter shoot (562.32, 569.33, 562.82), male flowers per meter shoot (552.09, 558.90, 555.50), female flowers per meter shoot (10.23, 10.34, 10.29), male: female flower ratio (53.97, 54.06, 54.02), fruit setting percentage (74.62, 75.22, 74.92 %), fruit drop (69.35, 68.75, 69.05 %), fruit retention (30.65, 31.11, 30.88 %), number of fruits per shoot (154.23, 157.37, 155.47) and fruit yield per tree (57.56, 61.17, 59.36 kg) in 2023, 2024 and pooled, respectively.
