Effect of different levels of nitrogen fertilizer and plant density on yield and yield components of canola
Journal Title: Scientific Journal of Crop Science - Year 2014, Vol 3, Issue 10
Abstract
In order to assess the effect of different levels of nitrogen and plant density on Performance and yield components in winter rapeseed (figure Hyola401) experiment in 1388, form band split plot, a the mold a randomized complete block design with four replications, in the city of Sari, was performed. Treatments were included plant density at three levels including 80, 100 and 120 plants per square meter, and nitrogen in four levels, including zero, 5/34, 69, and 5/103 Kg per hectare ,as urea, respectively. Results showed that different levels of plant density had significant effect on number of pods per plant, grain weight, grain yield and harvest index, whereas the number of seeds per pod, biological yield and grain yield influenced by this treatment, were not. Different levels of nitrogen fertilizer, a significant effect on all characteristics, except harvest index found. In this experiment, it was observed that increasing nitrogen levels, effects on all characteristics found. The maximum grain yield, the density of 120 plants per square meter, and maximum application of nitrogen (5/103 kg per hectare), with an average of 4012 kg per hectare, respectively.
