Pruning native plants can enhance seed dry weight, therefore leaf area would be increased which leads to more photosynthesis and seed storage materials [1,5] with the manipulation of the castor bean growth through the pruning at different planting densities concluded that the nipping of the apical shoot at the 6th; 10th and 14th node of the main stem reduced the plant height, but it did not affect seed yield.
