Poor seed set and filling is one of the most common problems encountered in sunflower cultivation.The yield of sunflower could be increased to a considerable extent by using brassinolide, a plant growth promoting substance, isolated from the pollen of rape, which prevents the formation of empty achenes, thus increasing the number of filled seeds.Field experiments were carried out at Tamil Nadu Agricultural University, Coimbatore, India during the summer (March-May) and South West Monsoon (June-September) seasons of 1997 to study the effect of brassinolide and NPK levels on the yield and yield attributes of sunflower.The experiments were laid out in a split plot design.
