The field experiment took place at the Fruit Research Station in Khengarvav, Junagadh Agricultural University, Junagadh, during the period of 2022 to 2023. The outcome of the experiment indicated that the application of NAA (Naphthalene acetic acid) at a concentration of 40 ppm resulted in various positive effects on the ber fruit. Notably, it led to significant increases in multiple parameters related to fruit quality and yield. Specifically, the use of NAA at 40 ppm resulted in the highest values for various attributes including fruit weight (27.83 g), fruit length (3.53 cm), fruit diameter (3.62 cm), fruit volume (29.31 ml), pulp weight (25.41 g), and the maximum pulp to stone ratio (11.62). Additionally, the application of NAA at this concentration led to a fruit set of 11.65%, a minimal fruit drop of 40.83%, and the highest recorded fruit yield per tree (11.88 kg/tree) as well as yield per hectare (3.29 t/ha). In conclusion, the study demonstrates that the use of NAA at 40 ppm has a positive impact on various parameters related to ber fruit production, including fruit quality and overall yield. The key findings emphasize the potential of NAA to enhance ber cultivation and its yield. This investigation contributes to the understanding of optimizing the growth and yield of ber fruit.
