The content of the present paper is summarized as follows:-
1) Complete with lime, Lot 6: the largest yield and the superior growth occurs in this cylinder which received three principal fertilizers constituents and lime; this is due to the improvement of the soil properties by the application of lime chemically and physically.
2) Complete, Lot. 1 comes next in its yield and growth and it still shows more satisfactory result than any other cylinder.
3) No kali, Lot. 4: comes after; in view of this fact it is seen that the kali has no serious effect upon the plant whether it is applied or not.
4) Phosphoric acid with lime, Lot. 8: showing mean result and it is rather good than otherwise.
It comes to this, that, as previously stated, the leguminous plant is able to fix the atmospheric nitrogen through their roottubercles, and the necessary amount of kali is always contained in the common soil, hence the nitrogen and kali can not be recognized as necessary constituents relatively, only the phosphoric acid, however, having no other means but to be applied artificially and therfore it should be one of the most valuable nutriments.
By this reason it may be imagined that, when the phosphoric acid was applied with the lime, both the constituents were brought together and a good result could be obtained.
5) No nitrogen, Lot. 2: and Phosphoric acid singly, Lot. 7: there can be no wide difference between these two cylinders in growth or yield of the plant, hence we consider it may be cultivated to a certain extent by using phosphoric acid alone.
6) No manure, Lot. 5: showed such a poor result that the yield of the cylinder amounted to only one six of that of complete cylinder.
7) No phosphoric acid, Lot. 3: gave most unsatisfactory result all ovar the trials.
According to our experiences in many cases it is usual that No phosphoric acid lot comes next to No. kali lot, notwithstanding this to show such a contrary result in this ca e is quite unknown, we could, however, recognize only the fact that the phosphoric acid is a more important constituent anyhow than the nitrogen in the “Hagi” culture.
In brief, the phosphate is one of the most valuable fertilizers in the culture of “Hagi” in accordance with our aforementioned result, we should therefore, in manuring other leguminous plants, pay special attention to this fact.
