Yellow Mustard (Brassica juncea) is a quick-growing annual seed crop prized for its many uses in the kitchen, garden, and beyond. This dual-purpose vegetable herb produces flavorful, slightly spicy greens that can be harvested young for salads or cooked as a nutritious leafy vegetable. The seeds can be ground for mustard spice or added whole to pickles and spice blends.

Versatile and easy to grow, Yellow Mustard is also used as a green manure, helping suppress weeds, improve soil structure, and naturally boost organic content. Its quick maturation rate makes it ideal for crop rotation and soil regeneration.
