Abstract

The field experiment of study the "Response of fertility levels on growth, yield and quality of Kharif onion" was conducted at farmers field at Trichy. The experiment comprising 8 fertility levels (Control, 75%, 100% and 125%) recommended dose of NPK vermicompost 2.5 t ha-1 with 25 per cent, 50 per cent and 75 per cent recommended dose of NPK. The application of 50 per cent recommended dose of NPK + vermicompost 2.5 t ha-1 significantly improved the plant height, number of leaves at harvest, equatorial diameter thickness of scale, volume of bulb, yield and TSS, vitamin "C" and allyl propyl disulphide content.
