Effect of Improved Fertilization on potato Yields in Tibet
IPNI-2007-CHN-XZ7
Effect of Improved Fertilization on Potato Yields in Tibet, 2008 The experiment was initiated in 2007 in a river valley in the Shannan region, the main potato production base in Tibet. The project was aimed at determining the optimal rates of N, P, and K fertilizers for potato and provide scientific fertilizer recommendations for the region. Treatments include an optimal treatment (OPT) using 105-75-120 kg N-P2O5-K2O/ha, three nutrient omission treatments, and an unfertilized check. Read more

| 2007 | Effect of Improved Fertilization on Potato Yields in Tibet, 2007 Potato is a very important and traditional food crop in Tibet where people rely on the tuber as a vegetable. Because of its good adaptability to poor soil conditions and harsh weather, it is scattered from mountains to river valleys on the plateau where it can grow and be harvested. Though it has a long history of cultivation in Tibet, balanced fertilization programs for this crop were just initiated in 2007. |
