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.
