2015-2017, seed crop of onion cv. Palam Lohit was sprayed with zinc, boron, molybdenum and their combinations. Foliar application of micronutrients was given as zinc sulphate, boric acid and sodium molybdate at a concentration of 5%, 1% and 0.05%, respectively, at 3 stages i.e. vegetative stage, prior to flowering and at seed set stage. The sprays of zinc @ 5% and boron @ 1% showed maximum values with respect to number of leaves plant-1 (12.67), leaf length (49.53 cm), plant height at final harvest (54.60 cm), number of umbel plant-1 (7.60), number of flower umbel-1 (465), number of seeds umbel-1 (386.67), seed yield (222.67 g plot-1 of 3.24 m 2 i.e. 618.52 kg ha-1), 1000 seed weight (3.97 g) and minimum for ovule to seed ratio (7.21) and days to bolting (113.43). The present studies revealed that onion seed crop sprayed with zinc @ 5% and boron @ 1% at vegetative stage, prior to flowering and at seed set stage significantly enhanced plant growth, yield contributing characters and seed yield. 2.

“…Seed production is widely adapted to temperate and subtropical regions. The quality and yield of onion seed could be increased by the use of improved varieties, increasing growing area, or by improving agronomic practices (Haque et al, 2014). According to onion seed traders, more than a 30% increase is observed in the adoption of hybrid onion CO (On) 5 seed (Pandiselvam, Pragalyaashree, Kailappan, Thirupathi, & Krishnakumar, 2014; Pandiselvam et al, 2020).…”

The post-harvest unit operations of onion umbels are being carried out manually. To mechanize this process, the present study was carried out to develop an onion umbels thresher. The developed machine works on the principle of abrasive and impact actions from rasp bars. Thresher performance was evaluated at different numbers of rasp bars (2, 3, 4, and 8 numbers), feed rates (25 ± 1, 30 ± 1, and 35 ± 1 kg/h), concave clearance (6.5 and 7.5 mm), and peripheral speeds (2.5 and 3.3 m/ s). At 35 ± 1 kg/h feed rate, 2 numbers of rasp bars, 7.5 mm concave clearance, and 2.5 m/s peripheral speed recorded higher threshing efficiency (97.82%) and lower seed damage (2.08%). The parameters such as the number of rasp bars on the threshing cylinder, peripheral speeds, concave clearances, and feed rates recorded significant effect (p < 0.01) on threshing efficiency and seed damage.

Bulb weight and plant density affect onion (Allium cepa L.) seed quality. A field experiment was conducted to investigate effects of bulb weight and plant density on yield and yield attributes of onion, cv. Taherpuri, seed. Bulbs with weights of 5 ± 2, 10 ± 2, and 15 ± 2 g, and plant densities of 100, 120, 133, 150, 160, and 200 plants/6 m 2 were used to determine effects. Plant emergence, number of green leaves/plant, umbel diameter, number of flowers/umbel, seed yield/plant, seed yield/plot, and germination percentage were measured. Maximum umbel diameter (7.46 cm), number of flowers/umbel (371.39), number of seeded fruit/umbel (245.16), seed yield/plant (2.94 g), and highest seed germination (96.45%) were with 100 plants/6 m 2 and highest seed yield/plot (286.00 g) was obtained at 200 plants/6 m 2 when heaviest bulbs were used. The lowest seed yield/plant was when small bulbs were grown at a density of 200 plants/6 m 2 . For quality onion seed production, a heavy bulb established at the lowest plant density provided the best results.
