Abstract

In order to determine the effect of different amount of nitrogen application in different SOWING DATEs on PHONOLOGICAL TRAITS, plant height and SEED YIELD OF CANOLA (Brassica napus L.) Hyola 401 cultivar, an experiment in a randomized complete block design arranged in a split-plot with four replications in Biekola Agriculture Research Station in Neka city during 2008-2009 was coducled. 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 of SOWING DATE and nitrogen for number of days to flowering, number of days to end of flowering, plant height, number of pods per main raceme, number of pods per plant, number of seeds per pod, 1000 seed weight and Seed yield. The nitrogen effect was significant on each studied traits except duration of flowering. Interaction SOWING DATE and nitrogen application were not significant for more studied traits except the number of pods per plant and 1000-seed weight. Among yield components, number of pods per main raceme and pods per plant had significant correlation with seed yield, indicating variations of these traits in different SOWING DATEs, and also more effect of different nitrogen levels on seed yield. Significant positive correlation was observed between seed yield and each phonological trait, indicating in first and second SOWING DATEs and also high amount of nitrogen levels make increasing amount of PHONOLOGICAL 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 the fifth SOWING DATE, the seed yield were 1754, 1835, 1973 and 2268 kg/ha respectively. Therefore one of the effective ways for compensating of decreasing yield components and seed yield due to late planting date is increasing amount of nitrogen application.
