Field Assessment of Two Micronutrients (Zinc and Boron) on the Seed Yield and Oil Content of Mustard

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−1) seed output, the maximum (1.9 T ha−1) and minimum (1.5 T ha−1) stover production, the maximum (4.9) and minimum (3.99) number branches plant−1, and the longest (114.6 cm) and shortest (87.44 cm) plant height were observed from 4 kg of Zn ha−1 and 0 kg of Zn ha−1, respectively. On the other hand, we discovered that applying 0.8 kg and 0 kg of B ha−1, respectively, resulted in the highest (1.6 T ha−1) and lowest (1.3 T ha−1) seed yield, the highest (1.8 T ha−1) and lowest (1.5 T ha−1) stover yield, the maximum (4.75) and minimum (4.02) number of branches plant−1, and the longest (118.7 cm) and shortest (85.15 cm) plant heights. The maximum seed (1.9 T ha−1) and stover output (2.0 T ha−1), tallest plant (140.9 cm), and most branches per plant−1 (5.47) were obtained when 4 kg of Zn ha−1 was given with 0.8 kg of B ha−1. 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−1 combined with 0.8 kg of B ha−1 may be advised as an effective approach in terms of seed yield and oil content.
