Effect of micronutrient application on quality and shelf-life of kharif onion (Allium cepa L.)

Onion (Allium cepa L.) is one of the most important commercial vegetable crops being grown all over the country. Onion belongs to family ‘Amaryllidaceae” and Locally known as Pyaj. The experiment was carried out during Kharif season of 2016-2017 at Tirhut College of Agriculture, Dholi kothi farm, Dholi (Muzaffarpur), a campus of Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar to study the effect of micronutrient application on quality and shelf-life of kharif onion. The experiment was laid out in RBD design with ten treatments and three replications. Significant observations were recorded for maximum TSS, dry weight of leaves/plant and dry weight of bulb/plant was with treatment T3 (NPKS + soil application of ZnSO4 @ 50kg/ha). The minimum sugar contains, bulb rotting and physiological loss of weight was recorded with treatment T5 (NPKS + soil application of Borax @ 10 kg/ha).The lowest sprouting percentage was found in treatment T3 (NPKS + soil application of ZnSO4 @ 50kg/ha).
