ABSTRACT
Introduction:
Canola is an important agricultural crop generally grown for oil and biofuel generation.
Materials and Methods:
The agroindustrial solid wastes of oregano and cumin wastes were used in a vegetation experiment to determine their effect on the nutrition, yield and quality of the canola plant (Brassica napus L.) The experiment was performed on 12 plots of 6 m2 and was conducted with four treatments of composted oregano and cumin wastes, mineral fertilization and control in three replications. Physical and chemical properties and macro-micro nutrients were determined in the soils at the beginning and the end of the experiment.
Results and Discussion:
The leaves showed sufficient levels of N, P, K, Ca, Mg and low sufficient levels of Na, Fe, Cu, Zn and Mn. The boron content of the leaves was insufficient. Manganese and B were affected significantly by the applications. The applications did not affect plant height, shoot and carob number per plant, and seed numbers per carob significantly. Statistically, the highest number of plants per m2 was observed in the plots to which cumin wastes were applied, and these plots also showed the maximum yield.
Conclusion:
Seed yield, protein and oil percentages were not affected significantly by the applications.
