Onion is one of the most important bulb crop grown all over the world. 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 experimental farm, Dholi (Muzaffarpur), a campus of Dr. Rajendra Prasad Central Agricultural University, Pusa (Samastipur), Bihar. The experiment was laid out in RBD (Randomized Block Design) with ten treatments and three replication. The crop was planted in a plot (size 3m × 2m) at a spacing of 15 cm × 10 cm. The observations recorded on at 30, 45 and 60 DAT of plant height and number of leaves per plant, average weight of bulb per plant, A grade bulb, B grade bulb, marketable bulb yield, marketable bulb percentage, total bulb yield was recorded. In treatment T3 (NPKS + soil application of ZnSO4 @ 50kg/ha). The maximum polar and equatorial diameter was recorded in treatment T6 (NPKS + soil application of Borax @ 15 kg/ha).The lowest collar thickness at 30, 45 and 60 DAT, neck thickness, doubler bulbs, bolters and C grade bulb was found in treatment T3 (NPKS + soil application of ZnSO4 @ 50kg/ha). Results were found to be significant in most of the growth and yield contributing parameters of Kharif onion.
