The Institute of Agricultural Science carried out fertilization experiments on rice varieties
The results showed that under the same other conditions, if potash fertilizer was more than phosphate fertilizer, variety 1 grew better than variety 2, and if phosphate fertilizer was more than potash fertilizer, the growth of variety 1 was better than that of variety 1
Except potash fertilizer and phosphate fertilizer, Variety 1 and Variety 2 do not need other fertilizers.
