1. Purpose
In order to test the quality improvement and yield-increasing effect of Dora Polytite on potatoes, the open field cultivation method was used to study the fruit weight and inside quality in the harvest.
2. Materials & Methods
2.1．Materials
The potato variety tested was’ Weiyu’, Dora Solution is based on Dora Polyite, NPK fertilizer.
2.2．Methods
The experiment was conducted in Guangming Village, Changshu, Jiangsu Province. The application of Polytite started from soil application, seedling stage, vegetative stage, until fruiting.
Group A: Control, use regular fertilizer.(MKP + NPK15-15-15)
Group B: Apply Dora Polytite, starting from soil application, seedling stage, and vegetative stage, until fruiting, along with the same fertilization in Group A.
Collect the data on potato yield, size, potato starch, and VC content.
3. Trial Data Collection
4. Test Results
4. 1. As illustrated in Figure 1, the implementation of Dora Polytite results in a 17.3% increase
in crop yield relative to the control group. The bar chart clearly demonstrates that the
application of Dora Polytite, represented by the right bar, led to a significantly higher yield
for the treated crop compared to the yield for the untreated control crop, shown by the left
bar.
This substantial augmentation in yield highlights the potential benefits of utilizing Dora
Polytite as an agricultural input for increasing crop productivity and farmer profitability.
4. 2. As is evident from Figure 2, the size distribution of potatoes skews substantially larger
for the treated group compared to the control group. The histogram illustrates that the treated crop exhibited a peak frequency of potatoes within the 15-16.9 cm size range, represented by the taller red bar, indicating that the majority of the potatoes from this group fell within this large size category.
In contrast, the histogram shows that potatoes from the control crop demonstrated a peak frequency within the 12-14.9 cm size range, represented by the taller blue bar, signifying that most of the potatoes from this group were of a smaller size. These results imply that the treatment contributed to a notable rightward shift in the size distribution towards larger potato sizes.
4. 3. Figures 3 and 4 provide a visual demonstration that the treated group exhibited
considerable advantages in terms of both starch and vitamin C content relative to the control
group. As illustrated in Figure 3, the bar chart shows that starch content for the treated crop,
represented by the right bar, was markedly higher than starch content for the untreated
control crop, represented by the left bar.
This indicates that the treatment resulted in a significant increase in the amount of starch accumulated by the crop. Similarly, as depicted in Figure 4, the histogram demonstrates that vitamin C content for the treated crop, shown by the taller blue bar, was substantially elevated compared to vitamin C content for the control crop, shown by the shorter bar. This suggests that the treatment was effective at enhancing vitamin C biosynthesis and accumulation within the crop. Taken together, Figures 3 and 4 show that the treatment conferred strong benefits for both starch and vitamin C production.
5. Conclusion
The key findings are:
1. Dora Polytite increased yield by 17.3%.
2. Dora Polytite treated potatoes were larger in size.
3. Dora Polytite enhanced starch and vitamin C content.
4. Dora Polytite shows the potential to boost crop productivity and marketable yield.
The recommended dosage of Dora Polytite is 10-15L/Ha with (drip) irrigation or 500 times
of foliar spray.
