Abstract
A B S T R A C T A field experiment was carried out in two successive winter seasons of 2011/2012 and 2012/2013 to study the effect of nitrogen sources (ammonium nitrate, ammonium sulphate and urea) and rates (30, 45 and 60 kg N/fed.) on the productivity and nutritional value of canola plant grown in calcareous soil at El -Areish Agricultural Research station, )ARC) North Sinai Governorate, Egypt (lat. 31.05 and long. 33.50 and 30.57m above the mean sea level). The main results were: In most cases, ammonium nitrate achieved a significant positive effect on most yield characteristics and seed yield as well as N, P, K, Oil and protein percentages as well as Oil yield in both seasons. However, branches number, plant highest, N content and protein % of seed did not respond significantly toward the nitrogen sources in first season, flowering 100 % in the second one as well as flowering 50 %, P content and oil % in both seasons. The highest nitrogen level significantly affected positively all canola tested parameters compared to other levels in both season. Generally, the highest obtained values for most characteristics of canola under investigation were achieved when the plants received ammonium nitrate with highest rate. Meanwhile, there were insignificant differences due to the interacted treatments on No. of branches / plant in the first season.
