dc.description.abstractA field experiment entitled “Integrated Nutrient Management in onion (Allium cepa L.) cv. N-53” was conducted during the rabi season in 2014-15 at the Horticulture cum Instructional Farm, Department of Horticulture, Rajasthan College of Agriculture, Udaipur, Rajasthan. The objectives of experimentation were to assess the effect of inorganics, organic sources, bio-fertilizers with reduced level of inorganic fertilizers on growth, yield and quality of onion and economics of the treatments and NPKS status of soil befor and after completion of crop. The experiment consisted of thirteen treatments. The results were revealed that the application of 60 per cent recommended dose of NPKS + NC 6 q ha-1 + VC 20 q ha-1 + Azotobacter + PSB (T12) recorded significantly maximum growth parameters in terms of plant height at 30, 60 and 90 DAP (19.24 , 29.71 and 41.94 cm) respectively, number of leaves per plant (3.27, 5.33, 7.60) and minimum bolting percent (2.25%) at 90 DAP followed treatment T13 by 40 percent recommended dose of NPKS + NC 9 q ha-1 + VC 30 q ha -1 + Azotobacter + PSB. Similarly, the yield components of onion viz., bulb diameter (5.20), fresh weight of bulb (52.32 g), yield per plot of bulb (16.05 kg) and yield per hectare (27.17 t) followed by treatment T13 with the application of 40 percent recommended dose of NPKS + NC 9 q ha-1 + VC 30 q ha -1 + Azotobacter + PSB. The bulb yield of onion was increased 16.45 per cent over recommended dose of 100 % NPKS (120:60:60:40 kg/ha) through inorganic fertilizers.

The bulb yield of onion was increased 16.45 per cent over recommended dose of 100 % NPKS (120:60:60:40 kg/ha) through inorganic fertilizers. The quality parameters were reaveled that the maximum value of TSS (15.19%), chlorophyll content of leaves at 90 DAP (0.76 mg), carbohydrate content (8.82%) dry matter content (16.39%), ascorbic acid (13.01 mg), protein content (6.10%), sugar content (6.70%) and pyruvic acid content (2.73 umol/100g) was achieved by combined application of 60 percent recommended dose of fertilizer of NPKS + NC (6q/ha) + VC (20q/ha) + Azotobacter + PSB (T12). However, treatments T4, T8 and T9 were at par with each other in respect to quality parameters. Similarly, the maximum uptake of NPKS (233.53 kg ha-1, 52.78 kg ha-1, 297.99 kg ha-1 and 238.03 kg ha-1) was recorded in the treatment T12 (60 percent recommended dose of fertilizer of NPKS + NC 6 q ha-1 + VC 20 q ha-1 + Azotobacter + PSB), followed (229.51 kg ha-1, 52.78 kg ha-1, 290.14 kg ha-1 and 221.26 kg ha-1 ) by T13 (60 percent recommended dose of fertilizer of NPKS + NC 9 q ha-1 + VC 30 q ha-1 + Azotobacter + PSB) in comparison of T1 treatment (100 % RDF of NPKS 120:60:60:40 kg ha-1 through chemical fertilizers). After final harvesting of onion, the maximum available nitrogen NPKS (195.21 kg ha-1, 28.24 kg ha-1, 265.90 kg ha-1 and 15.68 kg ha-1), were resulted with the application of T12 treatment in comparison T1. The application of integrated nutrients also improved the post harvest fertility status of the soil after harvest of the crop. As far as economics is concerned, maximum net return of 􀀀 325507 ha-1 and benefit cost ratio 3.97 was also recorded by the application of 60 percent recommended dose of fertilizer of NPKS + NC 6 q ha-1 + VC 20 q ha-1 + Azotobacter + PSB over recommended dose of NPKS (120:60:60:40 kg ha-1) through chemical fertilizersen_US
