Abstract:
An experiment was conducted to evaluate four aonla varieties viz; Chakaiya, NA-7, Kanchan and BSR 1 during 2017 – 2020 for their yield and quality characters at Regional Research Station (RRS), Tamil Nadu Agricultural University, Aruppukottai, Virudhunagar Dt., Tamil Nadu state in twelve years old aonla plantation under dry vertisol condition. The plant height varied from 2.77 to 5.37m in all varieties. The number of primary and secondary branches was ranged between 2.33 to 5.53 and 5.33 to 9.62 respectively. The increased stem girth of 79.01cm observed in the variety Kanchan. The variety BSR 1 showed enhanced plant spread in both East – West (4.53 m) and North – South (4.37 m). The aonla variety Chakaiya showed higher individual fruit weight (34.31 g) and pulp weight per fruit (32.03 g). Kanchan recorded the increased fruit diameter (40.79 mm) and reduced seed weight per fruit (1.55 g). The increased number fruits per tree (3744.33) and reduced individual fruit weight (13.68) was recorded in BSR 1. The aonla variety NA 7 showed increased yield per tree of 72.79 kg and yield per ha of 19.62 t. The enhanced TSS content of 15.33⁰ Brix was observed in the variety BSR 1.
