Abstract

In order to study the effect of various amounts of nitrogen (N) and zeolite (clinoptilolite) on the yield of winter canola (Brassica napuse L. ) and nitrogen leaching, in a light soil, a field experiment was conducted in the research farm of Tarbiat Modares University, on 2012-2013. The experiment was conducted as factorial trial in a randomized complete block design with three replications. The experimental factors contain zeolite (0, 3, 6 and 9 t. ha-1) and nitrogen (90, 180 and 270 kg ha-1 in urea form). The result showed that the highest Grain yield (2452 kg/ha) obtained from N270Z9 treatment and N90Z0 produce the lowest Grain yield (1569 kg/ha). Moreover using 270 kg N/ha without zeolite (N270Z0) has the highest amount of N leaching (142 kg/ha). zeolite application has significant effect on the reduction of N leaching in each N level. It could be concluded that a combined application of zeolite (9 t. ha-1) and chemical N (270 kg ha-1) for canola production is recommended to ensure an acceptable yield and for environmental protection from excess N leaching.
