Method of Fertilizer Application:

TSP, MP, Gypsum and ZnSO₄ all these fertilizers should be applied during final land preparation. Urea should be applied in three equal splits. The 1^st 1/3^rd is applied at 20 DAT as top dressing. 2^nd 1/3^rd is applied during early tillering stage at 30-35 DAT and last 1/3^rd at panicle initiation stage 50-55 DAT as top dressing.

Reasons for Split Application of Urea:

Urea becomes available in 3 days after application and remain available in one week. It is lost easily through leaching and volatilization.
