The present study was carried out to examine the effect of integrated nutrient management on the growth and yield of sunflower. Treatments included T1=Control (untreated), T2=N alone (100 kg per ha), T3=N+ P(100+50 kg per ha), T4=N+ P+K (100+50+50 kg per ha), T5=NPK+Boron (100+50+50 kg per ha +B@2g/L water), T6=NPK+ Humic acid (HA): (100+50+50 kg + HA @ 10 kg per ha) and T7=PK (Basal) + N in the form of urea as foliar spray. Observations were recorded on various characters of economic importance such as: seed germination, plant height (cm), stem girth (cm), head diameter (cm), number of seeds per head, weight of seeds per head, seed index/1000 seed weight (g), seed yield per ha (kg), harvest index (%) and oil content (%). The results indicated that all the growth, seed yield characters and oil content were remarkably influenced by various integrated nutrient management approaches with the exception of seed germination, where non-significant influence was recorded.
