Abstract

A study was conducted during the season of 2022-23 at the fruit research station in Imalia, which is affiliated with the Department of Horticulture at the JNKVV in Jabalpur. The objective of the study was to evaluate the positive effect of foliar sprays containing NAA, Urea, Nano-urea, and Biofertisol on the fruit quality of mango (Mangifera indica L.) cv. Langra. The experiment was laid out in Randomized Block design in three replications and all the treatments were replicated thrice by using the single tree as a unit. Each treatment was carried out with one tree for each replication.  At the full bloom and pea stage, the spraying of three different concentrations of NAA (20 ppm, 30 ppm, and 40 ppm), Urea (2%, 3%, and 4%), Nano-urea (0.2%, 0.3%, and 0.4%) and Biofertisol (5 ml/l, 10 ml/l, and 15 ml/l) was compared with the control, which consisted of no spraying. According to the findings of the experiment, applying a foliar spray containing 40 ppm of NAA resulted in a significant improvement in the quality parameter, as measured by a maximum TSS value of 22.22 oBrix, a maximum TSS: acid ratio of 117.13, maximum ascorbic acid content of 26.70 mg/100g, a minimum acidity content of 0.19%, and reducing sugars of 6.74% and total sugars of 17. During the evaluation, it performed at the same level as T3 (NAA 30 ppm), T2 (NAA 20 ppm), and T7 (Urea 4%).
