Phosphorus (P):
Critical for establishing an extensive root system and enhancing nitrogen-fixing nodule formation.
Promotes timely ripening and increases the number of filled pods and shelling percentage.
Potash (K):
Maintains plant turgor and controls stomatal movement, improving drought tolerance.
Essential for moving sugars and photosynthates from leaves to developing pods.
Significantly improves kernel size, test weight, and oil content.
Sulphur (S): As an essential element for oilseed crops, sulphur is vital for synthesizing methionine and cysteine amino acids, directly increasing oil yield and protein content.
Calcium (Ca):
The most critical nutrient for preventing “pops” (empty pods).
Essential for proper plumule development; a deficiency can lead to darkened plumules and poor seed germination.
Reduces susceptibility to pod rot and helps prevent aflatoxin contamination.
Zinc (Zn):
Vital for auxin production, which promotes cell division and overall plant vigor.
Acts as a metal activator for several enzyme systems and aids in chlorophyll formation.
Boron (B):
Crucial for flowering, pollen tube germination, and effective pod setting.
