The document discusses nutrient management practices for sunflower. It recommends applying the right quantity, form, time and method of nutrients. The recommended NPK application rates vary by state and type of cultivation. Other important nutrients for sunflower include sulfur, boron and zinc. Studies showed increasing yields with nitrogen rates up to 120-140 kg/ha, and benefits of potassium and sulfur applications. Integrated nutrient management using organic and inorganic sources provided better yields and quality than inorganic-only applications.

15. 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

 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
