Tomatoes are one of the most widely consumed fruits globally, and their quality plays a crucial role in determining their market value and consumer acceptance. The application of nano-fertilizers, such as nano urea, has emerged as a promising approach to enhance crop productivity and quality. In this context, a study was conducted to investigate the "Impact of nitrogenous fertilizers (Urea and Nano Urea) on Quality and Sensory Attributes of Tomato Fruits" at the University of Horticultural Sciences, Bagalkot, during 2022-2023. A randomized complete block design with 12 treatments and 3 replications was employed for testing different levels of nitrogen (100%, 75%, and 50%) applied through urea and nano urea (2 ml L^-1). The results revealed that, the plants treated with 100% RDN: 50% as basal dose of urea and another 50% through foliar application of nano urea (2 ml L^-1) at 30 and 45 DAT (T₄) exhibited superior fruit quality, characterized by optimal firmness (1.47 N), fruit colour with respect to L*, a* and b* value (37.54, 39.79 and 27.08, respectively), and sensory scores for color (8.67), texture (8.67), appearance (8.67), and overall acceptability of the fruits (9.00). These findings highlight the potential of nano urea in enhancing tomato quality.
