Abstract
At the Faculty of Agriculture Research Farm in Wadura, a field experiment was carried out for two consecutive Rabi seasons in 2020 and 2021 to determine the impact of integrated nitrogen management on onion (Allium cepa L.) yield and quality. Randomized block design (RBD) was used to set up the experiment, and the treatments were run in triplicate. When compared to other treatments, the onion yield in the plots receiving 50% N through vermicompost and 50% N through urea during Rabi 2020 and 21 was significantly higher (24.29 t ha-1 and 24.43 t ha-1, respectively), although it was comparable to the treatment receiving 50% N through FYM and 50% through urea. The quality parameters such as ascorbic acid, total soluble solids and pyruvic acid were also found higher in treatments receiving 50 per cent nitrogen through organic sources either through farmyard manure or vermicompost.
