Abstract

A field experiment was conducted in Akola, Maharashtra, India, to determine the effect of integrated nutrient management on growth, yield and quality of Onion during the rabi season of 2009-2010. Significantly higher values of all growth attribute parameters were recorded in the treatment (T7) i.e. application of 75 % RDF + 1.65 t ha-1 VC and Azotobacter, PSB each 5 kg ha-1 to the crop found to be sound integrated practice, where it recorded maximum plant height (84.95 cm), number of leaves (11.02), chlorophyll content (1.66 mg 100 gm-1), diameter of bulb (7.33 cm), weight of bulb (75.26 gm), yield (11.23 kg plot-1, 416.04 q ha-1), total soluble solids (14.26 %), oleoresin content (249.12 gm kg-1) over all the other treatments. Whereas Minimum (0.94 cm) neck thickness was recorded in control and minimum (120.53) days required for maturity was observed in T12 i.e. RDF+ Azotobacter and PSB each 5 kg ha-1.
