Split application of K is useful in high rainfall areas to save on Leaching.
Application of potassium in split doses enhanced the enzymatic activities, probably causing higher mobilization of nutrients in soil and plant and translocation of photosynthetic in plant system, which ultimately resulted in higher grain and straw yields.
When soil loses essential water-soluble nutrients needed for crop growth due to excessive rain or irrigation, the process is referred to as leaching.
