The average yield was 4.42 kg. 329.86% higher yield was obtained from the treated trees than from the control trees. Indoor analysis showed that the treated trees gained 5.5 g of fruit weight per plant compared with the control, the weight of seed kernel was 0.16 g lighter, and some of the kernels were burnt, and the edible rate increased by 5.85 percentage points, which was a very significant effect.
