Effect of Planting Geometry and Organic Sources of Nutrients on Keeping Quality of Onion ( allium Cepa L.) Cv. Bellary Red

The results obtained in the experiment revealed that, the minimum PLW and rotting (17.33 and 21.94%, respectively at 120 DAS) was recorded with the application of 50 per cent FYM (12.50 t ha- 1) + 50 per cent VC (2 t ha-1) + biofertilizers ( Azospirillum and phosphate solubalizing bacteria @ 5 kg ha- 1 each) with 15 cm x 10 cm spacing and sprouting was less when crop provided with 50 per cent FYM (12.50 t ha-1) + 50 per cent VC (2 t ha-1) with 15 cm x 10 cm spacing. However, with respect to bulb quality parameters, application of 50 per cent FYM (12.50 t ha-1) + 50 per cent VC (2 t ha-1) + biofertilizers ( Azospirillum and phosphate solubalizing bacteria @ 5 kg ha-1 each) with 15 cm x 10 cm spacing recorded maximum values (13.27, 13.36 and 49.28 % of TSS, dry matter and marketable bulbs at 120 DAS, respectively) followed by the crop nourished with 50 per cent FYM (12.50 t ha-1) + 50 per cent VC (2 t ha- 1) + biofertilizers ( Azospirillum and phosphate solubalizing bacteria @ 5 kg ha-1 each) with 15 cm x 15 cm spacing.
