Mid-Season Use
Cotton at first boll set receives 150–200 kg/ha NK 15-15 to support boll development and fibre quality. Sunflower at bud formation uses 120–180 kg/ha for head size and oil content. Apply to moist soil and incorporate where possible.
FAQ
How does NK 15-15 compare to applying urea and MOP?
NK 15-15 saves one field pass and ensures uniform N:K ratio at every application point. Cost per kg nutrient is typically 5–8% higher than straight fertilizers but operational savings offset the premium.
Can NK 15-15 be used at planting?
Only if soil P is confirmed adequate. Most programmes use NP or NPK at planting and switch to NK 15-15 for mid-season top-dress.
Is NK 15-15 available in bulk for blending?
Yes. Bulk vessel or truck delivery for toll-blending with micronutrients or secondary products at regional blending plants.
