Abstract/ Executive Summary:

Seed production ability of three cultivars of onion was studied a the Bangladesh Agricultural University, Mymensing. the cultivars were Hissar-2, N-53 and Faridpur local. The Hissar-2 and N-53 are the cultivars of Indian origin and Faridpur local is an indigenous cultivar of Bangladesh. Under the experimental conditions, yield of seed was the highest in bulb-raised plants of Faridpuri local (1197.6 kg/ha) followed by the seed-raised plants of the same cultivar. Seed-raised of both the introduced cultivars failed to give a satisfactory yield of seed.

Keywords: Seed, Production ability, Onion

Location: Bangladesh Agricultural University, Mymensingh.

Start Date: 00-09-1980

End Date: 00-05-1981

Program Area: Seed Technology

Commodity: Onion

Objectives:

To investigate the seed production ability of three cultivars of onion under Bangladesh conditions.

Methodology:

The present research work on seed production ability of three cultivars of onion, namely, Hissar-2, N-53 and Faridpur local was carried out at the Bangladesh Agricultural University, Mymensingh during the period from September, 1980 to May, 1981. To compare the seed production ability of the three cultivars by seed-to-seed method with that of usual method practiced in Bangladesh, bulbs of the Faridpuri local cultivar were also planted.The experiment was laid out in the randomised complete block design with four replications. The size of unit plot was 4.88 m x3.66 m.The field plot was situated on a sandy-loam soil with a pH of 6.6. Seeds of all the three cultivars were sown in seed beds on 25 September,1980 and the seedlings were transplanted on 20 November, 1980. The bulbs of the Faridpuri local cultivar (Treatment-4) were planted on the same date of transplanting of the seedlings. Planting was done in single row system with a spacing of 30.5 cm x 15.2 cm. The basal dressing of cowdung manure, oil cake and triple super phosphate at the rates of 10 t, 404 kg and 127 kg/ha respectively were applied during the land preparation. Half of the total doses of urea and muriate of potash was applied during the final land preparation and the rest half was applied during the final land preparation and the rest half was applied in two equal top-dressings after 30 and 60 days of transplanting. The total doses of urea and muriate of potash were 101 and 76 kg/ha respectively. Irrigation, weeding and all other intercultural operations were done as and when needed. Mature seeds from the plants raised from mother bulbs of Faridpuri local were harvested during the period from 28 March to 10 April, 1981, and the seeds from the seed-raised plants of the same cultivar were harvested during 20 April to 30 April, 1981. While the seeds from the seed-raised plant of Hissar-2 and N-53 were harvested from 5 May to 15 May, 1081. The harvested seeds were dried, threshed , cleaned and stored in sealed polythene bags.
