Question
There is a mutual antagonistic effect on the uptake of
K, Ca & Mg. What is the ideal ratio of K, Ca & Mg for Groundnut?Solution
Groundnut is sensitive to imbalanced nutrient supply. The K:C: Mg ratio is more important than the total amount. Increase in conc. of Mg in nutrient solution decrease K uptake by groundnut & also decreases Ca uptake. The ideal ratio of K, Ca & Mg is 4:4:2.
