Abstract:
The experimental study entitled “Effect of integrated nutrient management on growth, yield and quality of onion (<em>Allium cepa </em>L.)” was carried out at the experimental farm of Department of Horticulture, Doon (PG) College of Agriculture Science &amp; Technology, Selaqui, Dehradun, Uttarakhand in the Rabi season of 2017-2018. The objective of the study was to investigate the effect of different treatments on growth, yield and quality of onion cv. ‘Palam Lohit’. In this study, 10 treatments, <em>viz</em>. T1: Control: RDF (FYM @ 250 q ha<sup>-1</sup> and NPK- 125:76:60 kg ha<sup>-1</sup>), T2: RDF (NPK) + VC @ 8 t ha<sup>-1</sup>, T3: 75 % RDF + Azotobacter, T4: 75 % RDF + Azotobacter + VAM, T5: 50 % RDF + Azotobacter, T6: 50 % RDF + Azotobacter + VAM, T7: VC @ 8 t ha<sup>-1</sup> + Azotobacter + VAM, T8: FYM @ 25 t ha<sup>-1</sup> + Azotobacter + VAM, T9: VC @ 4 t ha<sup>-1</sup> + Azotobacter + VAM and T10: FYM @ 12.5 t ha<sup>-1</sup> + VC @ 4 t ha<sup>-1</sup> + Azotobacter + VAM, were compared in a Randomized Complete Block Design (RCBD) having three replications with a plot size of 3.0 Ñ… 1.5 m<sup>2</sup> and a plant spacing of 15 cm Ñ… 10 cm. The observations were recorded on leaf length (cm), no. of leaves per plant, bulb yield per plot (kg), bulbs yield per hectare (q), total soluble solid (°Brix) and neck thickness (cm). The results revealed that T4 (75 % RDF + Azotobacter + VAM) was rated as the best treatment for majority of characters like leaf length (cm), no. of leaves per plant, bulb yield per plot (16.80 kg), bulb yield per hectare (373.33 q) followed by T2. Therefore, on the basis of present study, it is concluded that application of biofertilizers (Azotobacter and VAM) in combination with 75 % RDF can be suggested cost effective combination for enhanced growth, yield and quality onion production in mid hills of Uttarakhand.
