Abstract

The experiment was conducted during 2013-14 at spices Research Sub-centre, Faridpur and farmer’s field of Faridpur sadar upazila and 2014-15 at farmer’s field of Faridpu rsadar upazila to validate onion seed production technologies at Faridpur region. The experiment was conducted during rabi season. In 2013-14, at farmer’s field the experiment was conducted in randomized complete block design with eight replications and at SRSC the experiment was conducted in randomized complete block design with four replications and in 2014-15, the experiment was conducted in randomized complete block design with four replications. In 2013-14, three treatments viz, 1) SRC recommended practice: planting time (2nd week of November) + bulb size (15-20g) + spacing (20 cm ×15 cm) + irrigation (five at 25, 50, 75, 100 and 125 DAP) + weeding (four at 15, 25, 45 and 60 DAP) + fungicide (Rovral+ Ridomil Gold and Nativo four alternate spray when disease appears) + insecticide ( 2-3 spraying of Regent when thrips appears) 2) Farmer’s practice: planting time (2nd week of November) + bulb size (15-20g) + spacing (30cm × 20 cm) + irrigation ( one at 15-20 DAE) + weeding (one followed by irrigation + fungicide (Rovral and Score applied at 7days interval after umbel brusting)+insecticide (Confidor applied when thrips appears) and 3) Farmer’s practice +1irrigation more (additional irrigation was given at 50 DAP) were studied. In 2014-15, one additional treatment viz, Farmer’s practice + SRC spacing was included to the above treatments. The results of the study revealed that management practices had significant impact on yield and yield attributes of onion and among the treatments the highest yield was found from SRC recommended practice in both the years. Significantly highest yield (536.5 kg) was recorded from SRC recommended practice and the lowest yield (413.5 kg/ha) was recorded from Farmer’s practice.
