A master's thesis at the College of Agriculture, University of Basra, investigated "The Response of Indian Mustard to Phosphate and Potassium Fertilization under Plant Density."

The thesis, presented by researcher Anfal Amin Khudair, aimed to determine the optimal combination of phosphorus and potassium fertilizers applied to the soil, the best plant spacing to achieve optimal density, and the interaction between these factors and its effect on the growth, yield, and quality of mustard oil.

The study examined the effect of nine combinations of phosphate and potassium fertilizers and two plant spacings on the growth, yield, oil quality, and medicinally active compounds of Indian mustard seeds.

The study recommended fertilizing with phosphate at a rate of 80 kg P/ha and potassium at a rate of 60 kg K₂O/ha, and planting with a spacing of 40 cm between mustard plants. It also recommended introducing and comparing several varieties of Indian mustard with the local variety to determine the best varieties in terms of oil production, both in quantity and quality.
