بررسی تأثیر میزان بذر و روش کاشت بر عملکرد و اجزای عملکرد دانه کلزا

In order to determine the best planting pattern and optimum plant density of rapeseed, an experiment was carried out in 2011 and 2012, at Agricultural Research Station of Varamin. The experiment was a split-plot design on randomized complete block basis with four replications. The main plots included four planting methods pattern (one row on furrow with 60 cm width, two rows on furrow with 60 cm width, two rows on furrow with 50 cm width and one row on furrow with 50 cm width) and the sub plots included three seed rates (6, 8 and 10 kg/ha). The results of combined analysis showed that effect of planting pattern was significant on characteristic such as number of pod per plant, number of seed per pod, 1000 seed weight and seed yield. The effect of interaction between planting pattern and seed rates was significant on number of pod per plant and 1000 seed weight. The results of mean comparison analysis of this experiment showed that the high best results for investigated characteristic were obtained from application of 6 kg/ha seed rate and planting pattern of one row on furrow with 60 cm width.
