>> Saturday, August 21, 2010
Crop name: Mustard (Brassica sp.)
Origin: Eurasian origin.
Climate: Grows well in cool and moist climate (below 25c). In general, high temperatures (higher than 25) cause a sharp decrease in oil content.
Soil: Fairly tolerant to salinity and prefer well-aerated soils and cannot resist
water logging. It can be grown in light, sandy soils.
In Bangladesh, silty soil.
Land preparation: 3 ploughing + 4 laddering in light soils.
6 ploughing + 7 laddering in heavy soils.
Varieties: SS- (Sonali sarisha), TS- 72 (Kalyania), Sampad, Sambal, Daulat, Tori-7, Rai-5, BARI Sarisha-6, 7, 8
Seed rate & Sowing time: -Traditionally last week of October. Better time for
sowing mustard is November 1-15 in dry areas.
-November 15- early December in other areas.
-Generally seed rate is 7.5-10 kg/ha.
-Both line sowing and broadcasting.
-In case of line sowing 25-30 cm apart.
Weeding: Two weeding at 15 and 40 DAS after sowing.
Water management: Irrigated crop, in adequate moisture supply, yield
Increases sharply.
-Very sensitive to water stress in case of flowering and pod filling.
-Two irrigations- one at 35 DAS & another at pod filling stage.
-½ kg Urea + all fertilizers should be applied during land preparation.
-Rest of urea applied during flowering.
Harvesting: The crop is taken to be mature when stems and pods become yellow,
Seed takes black and the pods give rattling sound.
Yield: Average yields 700 kg/ha.
