Abstract

                                A field experiment was conducted at Agricultural Research Station, Bhavanisagar, to evaluate the yield, quality and economics as influenced by different drip fertigation treatments on aggregatum onion during kharif 2017. The treatment consists of 100 per cent N through fertigation with 100 per cent P and K applied as basal, 100 per cent N and K through fertigation with 100 per cent P applied as basal, 100 per cent N, P and K through fertigation, 75 per cent N, P and K through fertigation and 25 per cent N, P and K applied as basal, 75 per cent N through fertigation with 75 per cent P and K applied as basal, 75 per cent N and K through fertigation with 75 per cent P applied as basal, 75 per cent N, P and K through fertigation, 75 per cent of 75 per cent N, P and K through fertigation and 25 per cent of 75 per cent N, P and K applied as basal, 50 per cent N 100 per cent P and K applied as basal and 50 per cent N applied on 30 days after transplanting (DAT), absolute control. Among different fertigation treatments imposed 100 per cent N, P and K through fertigation registered higher quality, yield (23.24 th) and was comparable with 75 per cent N, P and K through fertigation.

Key words : Aggregatum onion, Drip fertigation, Yield, Quality and Economics.
