In an experimental investigation, we looked into how different zinc (Zn) and boron (B) dosages affected the production and the amount of oil in mustard. Zn and B treatments, respectively, were separated into four levels: 0, 1, 2, 4, and 0, 0.4, 0.6, and 0.8 kg per hectare. We observed considerable Zn as well as B effects on mustard yield and its oil content. The maximum (1.6 Ton per hectare) and minimum (1.3 T ha<sup>−1</sup>) seed output, the maximum (1.9 T ha<sup>−1</sup>) and minimum (1.5 T ha<sup>−1</sup>) stover production, the maximum (4.9) and minimum (3.99) number branches plant<sup>−1</sup>, and the longest (114.6 cm) and shortest (87.44 cm) plant height were observed from 4 kg of Zn ha<sup>−1</sup> and 0 kg of Zn ha<sup>−1</sup>, respectively. On the other hand, we discovered that applying 0.8 kg and 0 kg of B ha<sup>−1</sup>, respectively, resulted in the highest (1.6 T ha<sup>−1</sup>) and lowest (1.3 T ha<sup>−1</sup>) seed yield, the highest (1.8 T ha<sup>−1</sup>) and lowest (1.5 T ha<sup>−1</sup>) stover yield, the maximum (4.75) and minimum (4.02) number of branches plant<sup>−1</sup>, and the longest (118.7 cm) and shortest (85.15 cm) plant heights. The maximum seed (1.9 T ha<sup>−1</sup>) and stover output (2.0 T ha<sup>−1</sup>), tallest plant (140.9 cm), and most branches per plant<sup>−1</sup> (5.47) were obtained when 4 kg of Zn ha<sup>−1</sup> was given with 0.8 kg of B ha<sup>−1</sup>. However, while Zn and B were not applied, the lowest output for all of the crop attributes assessed was observed. As a result, for mustard, 4 kg of Zn ha<sup>−1</sup> combined with 0.8 kg of B ha<sup>−1</sup> may be advised as an effective approach in terms of seed yield and oil content.
