Time of application
Irrigated crop Basal application: 50% N + full of P & K Splitting of N- 25% at 30 DAS (button stage) and 55 DAS (flowering)
stage. Rainfed crop
Basal application: 50% N + full of P & K Splitting of N- remaining N at 30 DAS

Method of application Basal application of fertilizer with drilling If seeding is done in plough furrows, a tube may be attached
for proper fertilizer placement N splitting by broadcasting Micronutrients sprayed

Form of fertilizer
SSP is the best source of phosphorus supplyBased of soil test value
