Abstract
In this experiment, Five N efficiency parameters, seed yield and seed oil content was investigated under different fertilizer management in field-grown canola plants. Treatments include four levels of nitrogen (zero, 50, 100 and 150 kg ha –1 ) as main factor and two levels of zinc sulfate (zero and 50 kg ha –1 ) and two levels of biological fertilizer (with and without) as sub-factor were arranged in a factorial design. The results showed that different treatments had significant effects on all the N efficiency parameters, seed yield and seed oil content. Highest value for N use efficiency, N agronomic efficiency and N recovery fraction were observed in the plants treated with combination of 50 kg ha –1 N and Zinc sulphtae. But the highest value for N physiological efficiency and seed oil content were observed in plants treated with combination of 50 kg ha –1 N and Zinc sulphtae and biofertilizer. Moreover, plants treated with 150 kg ha –1 N and Zinc sulphtae and biofertilizer had the highest seed yield and the lowest seed oil content. This study revealed that using integrated fertilizer management a considerable reduction in fertilizer N-demand is possible leading to lower N-balance surpluses in canola production, thus minimizing environmental risk.
