Planting arrangement were placed in two levels of diamond and square in main plots, nitrogen supply resources in three levels of chemical fertilizer, manure and vermicompost in sub plots and bush density in three levels of 30 × 30 cm, 40 × 40 cm and 50 × 50 cm in sub sub plots, too.
Traits such as bush height, stem diameter, number of leaves per bush, leaf and stem dry weight and lateral branches were Measured.
The results indicated that greatest bush height, number of leaves and lateral branches and dry weight related to usage of nitrogen fertilizer.
The greatest stem diameter, later...
