Abstract:
A field experiment was conducted to determine the response of integrated plant nutrition on growth, yield and quality of Onion at Department of Horticulture, Faculty of Agriculture, Annamalai University., During 2010 in randomized block design with eleven treatments of integrated nutrient management <em>viz</em>., T<sub>1</sub>- FYM 25 t ha<sup>-1</sup> + 100% RDF (60:60:30 kg NPK ha<sup>-1</sup>). T<sub>2</sub>-FYM 25 t ha<sup>-1</sup> + 75% RDF (45:45:22.5 kg NPK ha<sup>-1</sup>) + sulphur @ 45 kg ha<sup>-1 </sup>+ panchagavya 3%.
