Use and response to phosphorus by potato clones in two cropping systems
The selection of potato plants (Solanum tuberosum L.) that are efficient in the use of phosphorus (P) plays an important role in increasing crop productivity, reducing the cost of production due to the high price of phosphate fertilizers, as well as reducing the pollution of the environment due to t...
