بررسی تأثیر سطوح مختلف نیتروژن و روی بر کمیت و خواص کیفی کلزا در شرایط شور

in order to investigate the effects of the nitrogen and zinc fertilizer effect on yield and quality of two oilseed rape in saline conditions, a field experiment was conducted at Agricultural Research Station of East Azerbaijan Research Center for Agriculture and Natural Resources, Tabriz, Iran, in 2009-2010. The experiment was arranged by using a completely randomized block design based on factorial fashion with three replications. The experimental treatments included the nitrogen levels (0, 50 and 100 kg. ha-1), different zinc levels (0, 5 and 10 kg. ha-1) and salinity levels (8 and 16 dS/m). Based on results, nitrogen application had a significant effect of increasing plant height and grain yield of canola. However, oil percentage of canola was decreased as result to nitrogen levels. In addition, plant height and grain yield of canola were decreased by increasing salinity levels (from 8 to 16 dS/m).
