Abstract
In order to explore the effects of different sources and levels of nitrogen on agronomic characteristics of canola. Tow field experiments were conducted at the Experimental Farm, Faculty of Agriculture, Ismailia Governorate, Egypt during 2013/2014 and 2014/2015 seasons. Nitrogen fertilizer in the form of Ammonium Nitrate (AN) was added in two equal doses, the first dose, after three weeks of planting and the second one after seven weeks of planting at the levels of 0, 50,75 and 100 kg ha-1. But nitrogen in the form of Ammonium Sulfate (AS) was practical in one equal portion after sowing and before irrigation at four levels, i.e. 0, 15, 30 and 45 kg ha-1. Results designated that all agronomic characters increased with increasing N application, but the oil content diminished particularly with Ammonium Nitrate. Application of 100 kg N ha-1 in form of AN or 45 kg N ha-1 in form of AS chronicled the maximum seed yield in the two seasons. It could be determined that the cultivation of plants in the presence N in the form AN or AS enhanced the nutritional values of the yielded seed under the new reclaimed soils inEgypt.
