Abstract

In order to determine the effect of different amounts of nitrogen application in different SOWING DATES on phonological, characterictics and grain yield of canola (Hyola 401), the experiment, a randomized complete block design, arranged in a split-plot with four replications in Biekola Agriculture Research Station in Neka city during 2007-2008. Five SOWING DATES including 29 October, 8, 18, 28 November and 8 December were considered as main plots and four levels of nitrogen UREA FERTILIZER application including 150, 200, 250 and 300 kg/ha urea were considered as sub plots. Results revealed significant differences of sowing date and nitrogen for number of days to flowering, number of days to end of flowering, number of days to maturity, 1000 seed weight, biological yield and grain yield. The nitrogen effect was significant on each studied trait except duration of flowering and harvest index. The interaction between sowing date and nitrogen application were not significant for all studied traits except the number of days to maturity and 1000-seed weight. Significant positive correlation was observed between seed yield and each phenological trait, indicating in the first and second SOWING DATES and also high amount of nitrogen levels make increasing amount of phenological traits and seed yield.In the first sowing date the seed yield related to four nitrogen application levels were 2864, 3026, 3276 and 3707 kg/ha respectively. For fifth sowing date seed yields were 1754, 1835, 1973 and 2268 kg/ha respectively. Therefore one of the effective ways of compensating for decreasing yield components and seed yield due to late planting date is increasing the amount of nitrogen application.
