A field experiment was conducted during 2006-2007 and 2007-2008 seasons at Herbal garden, Rajendranagar, Hyderabad, India to study the influence of different sowing dates and spraying of brassinosteroid (BR) on yield and fruit quality of watermelon. The study consists of four sowing dates (October 4th week, November 2nd week, November 4th week and December 2nd week ) and two levels of brassinosteroid 0.1 and 0.5 ppm as foliar spray, and untreated control. Crop sown on December 2nd week was significantly superior over remaining other sowing dates and recorded highest yield. Spraying of BR 0.1 ppm at 2nd and 4th leaf stage was highly effective in increasing the yield of watermelon. The maximum number of fruits per plant was recorded in December 2nd week sowing and sprayed with BR 0.1 ppm. Crop sown on December 2nd week had significant influence on quality characters like total soluble solids, total sugars and lycopene content.
