Description The present investigation entitled “Effect of date of nursery sowing and seedling age on growth, yield and quality of Rabi onion in Chhattisgarh plains” was conducted at Research and Instructional Farm, Department of Horticulture, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur (Chhattisgarh) during Rabi season of year 2011-12.
The experiment was laid out in factorial randomized block design with three replications. The treatment consisted of twelve treatments of sowing date and seedling age viz; 25th Oct X 30 days (D1A1), 25th Oct X 40 days (D1A2), 25th Oct X 50 days (D1A3), 25th Oct X 60 days (D1A4), 5th Nov X 30 days (D2A1), 5th Nov X 40 days (D2A2), 5th Nov X 50 days (D2A3), 5th Nov X 60 days (D2A4), 15th Nov X 30 days (D3A1), 15th Nov X 40 days (D3A2), 15th Nov X 50 days (D3A3) and 15th Nov X 60 days (D3A4).
The different sowing dates and seedling ages exhibited significant influence on various growth, yield and yield attributing characters in the present study and their interaction was also found to be significantly affecting all these parameters.
All the growth and yield characters significantly declined with delayed sowing from 25th Oct to 15th Nov and advancement in seedling age (30 to 60 days old seedling). The treatment D1 (25th Oct) with A1 (30 days old seedling) significantly registered the highest performs in comparison to rest of the treatments.
Maximum plant height was recorded under (D1A1), number of leaves per plant (D1A1), pseudostem length (D1A1), pseudostem width (D1A1), equatorial diameter (D1A1), polar diameter (D1A1), diameter:length ratio (D1A1), weight of grade A bulbs (D1A1), weight of grade B bulbs (D1A1), weight of grade C bulbs (D1A4), weight of grade D bulbs (D2A3), weight of double bulbs (D1A1), total bulb yield (D1A1), marketable bulb yield (D1A1), average bulb weight (D1A1), average bulb dry weight (D1A1), bolting percentage (D1A1 and D2A2).
Minimum plant height was recorded under (D3A4), number of leaves per plant (D3A4), pseudostem length (D3A4), pseudostem width (D3A4), equatorial diameter (D3A4), polar diameter (D3A4), diameter:length ratio (D3A4), weight of grade A bulbs (D2A3), weight of grade B bulbs (D3A4), weight of grade C bulbs (D3A3), weight of grade D bulbs (D2A1), weight of double bulbs (D1A4), total bulb yield (D3A4), marketable bulb yield (D3A4), average bulb weight (D3A4), average bulb dry weight (D3A4), bolting percentage (D1A3, D2A4 and D3A1).
The quality character like TSS was not significantly affected due to different treatment combination.
It is suggested that sowing of onion should be done on 25th October and seedlings should be raised for 30 days for production of marketable yields. The similar treatment combination gave the best yields and highest net return of Rs. 209737.3 as compared with other treatment combinations.
The present investigations revealed that in case of delayed sowing, the transplanting of younger seedlings may improve the bulb yield in comparison to other seedlings
