Abstract
|
|
|
To confirm the increase effect of MNH₄ which has been compounded as a result of two years´ potted rice experiments, we have established simple experiment areas in the paddy field of Kyung-Puk, Kyung-Nam and Chon-Puk Provinces and have done the completely randomized design experiments with the following results.
1. Comparison of the gross weight of the harvested rice (Straw included) : The MNH₄ 1-area has produced 10-28% more harvest than that of control-area.
2. Comparison of the weight of the Unpolished Rice: The MNH₄ 1-area has shown 10-23% increase compared with the control-area.
3. In the comparison of the nutrients of the rice from the MNH₄-area with those of the rice from the control area, MNH₄-area showed increase of N₂, P₂O_5 and SiO₂ but a slight decrease of K₂O.
