Onion (Allium cepa L) is the most economical vegetable often used as a spice. The farming of onion on rainfed areas, by using broad casting method is very difficult. Broadcasting method results in the higher amount of seed rate, non-uniform distribution of seeds, poor bulb maturity, higher nutrient competition, and more over it is a time consuming and laborious process. By taking all these factors into consideration an animal drawn onion seeder was developed under rainfed onion crop cultivation with a reasonable cost of operation. The field area was divided into 6 no. of plots with length 20 m and width of 1.6 m. Number of germinated seedlings in a square meter, plant to plant spacing and row to row spacing were replicated 5 times in each plot with â…“rd, ½, â…â€rd volume of filling in drums. The number of seedlings/ sq. m, in â…“rd volume of drum filling with double row holes (29) were more and found to be 150 number, and single row holes (14) was less and found to be 52 number, In plant to plant spacing, ½ drum filling single row holes (14) gave more spacing which was about 10.57 cm and â…“rd drum filling double row holes (29) gave less spacing which was about 5.358 cm. In row to row spacing, with ½ filling single row holes (14) gave more spacing which was found to be 11.55 cm and with â…“rd filling double row holes (29) gave less spacing 6.073 cm. The seeder with single row holes open with â…†rd of drum filling was selected to drop the onion seed in the rainfed area. The recommended onion seedlings should be in the range of 75 to 80 per sq. m with a row to row spacing of 7.5 to 8 cm and plant spacing of 6 to 8 cm. The above recommendations were met with single row holes (14) opened with â…†rd of drum filling. Field capacity of the seeder with single row holes (14) open and â…†rd of drum filling were 0.32 ha/hr. Row to row spacing was 7.9 cm with germination percentage of 97.3. The cost of the developed animal drawn onion seeder was Rs. 16,100.
