| Abstract: | The experiment results show that nitrogen and phosphorus fertili-zation has significant increasing yield effects on the tobacco in Yuxi hilly region. The output value of applying nitrogen 3 Kg per mu is higher than that of applying nitrogen 2 Kg per mu. The most suitable ratio of N and P2O5 is 1 and 1 to 1.5. |
