Effect of potassium and phosphorus on yields and quality of cash crops
IPNI-2000-CHN-SN5
Effect of potassium and phosphorus on yields and quality of cash crops, 2001 Potassium (K) is one of the major factors influencing cash crop quality and yield in apple, grape, cotton, and several vegetables grown on loess soils [available K ranging from 100 to 271 parts per million (ppm)]. Locally it is believed that K has no effect on crop yields if available K is more than 100 ppm. The objective of this experiment is to change that perception. Read more
