11. Oilseeds are energy rich crop
Brassicasare also no exception and contain 25.7 MJ /kg of seeds
It is a annual herb
Harvest index 0.20 to 0.30%
Harvest index is positively correlated to yield
Morphology of Plant

12. •Rapeseed & Mustard -tropical& temperate zone crops
•In tropics at high elevation –1000 m
•Require relatively cool temperature for satisfactory growth & yield
•Temperature 3 to 40°C
•Optimum 18 -28°C. Cool and dry clear weather
•Seed oil content high at temperature 10 to 15°C
•10 hours brighter sunshine for growth and development
•Rainfall 350 -550 mm
•High rainfall, high humidity, cloudy atmosphere at flowering undesirable.
•Sensitive to frost –adverse effect on flowering pollen production & pollen viability.
CLIMATIC REQUIREMENTS

13. Wide range of soils –Alluvial, loamy to clay
Sarsonand Taramiramostly in light soils
Toria–loam to heavy soils
Raya –All types of soils
Mustard on any soil, rapeseed in light soil ideal
Well drained soil is more suitable
Water logging will affect the crop
Prefers neutral soil withstand some extent alkalinity
Come up will with residual moisture of rice fallows
SOIL REQUIREMENTS

14. SEASON
Most situated to rabi
Sowing starts from August & ends at December mid
Rapeseed requires early sowing
Taramirain mid September to October end
In Rajasthan Mid November to mid December

Varieties

16. Land Preparation
Requires fine seed bed as the seeds are small
Ploughing 3 -4 times followed by harrowing
After cultivation planking to conserve the moisture
Flat bed for using fertiseed drill

17. Optimum seed rate 4 -6 kg
3 -5 g/1000 seeds
As mixed & intercrop 1-2 kg
Spacing 30 x 10 or 30 x 15
Optimum population 22 to 33 plants/m

Seed rate & Spacing

18. Sowing
Sowing behind country plough
Sowing with ferti seed drill
Avoid shallow sowing, depth 3 -4 cm
Broadcastmethod can also adopted
Cover the seeds by planting to give better contact of seed & moist soil for
germination
Better germination & establishment soak the seeds over might with
one gunny bag
It can be mixed with equal quantity of sand for uniform distribution
It rains follow the sowing in a day or two adopt re sowing for better
establishment

19. •Apply 10 t of FYM/ha
-1
once in 2-3 years especially under rainfed
•If previous crop is heavily manured in irrigated condition, it can be raised with residual
fertility
•It removes huge nutrients
•General recommendation 60:40:40 for irrigated
•Half N at 30 DAS others as basal
•20 -40 kg elemental sulphur of soil with < 100ppm
•30:20:20 for rainfed -all basal
•Integrate with biofertilizer is desirable i.e. Azotobactor
•Some specific recommendation
•Rainfed brassica 40:20: 0 kg NPK/ha
•Irrigated toria 40:20:15 kg NPK/ha
•Irrigated Sarson 60:30:20 kg NPK/ha
•Irrigated Raya 80:40:25 kg NPK/ha
•All nutrient as basal
Manuring

20. Total water requirement 400 –600 mm
Flowering& pod formation & filling stage are critical to moisture stress
Two to three irrigation
One at rosette 20 –30 DAS
One at flowering 50 -60 DAS
One at pod or silique stage 80-90 DAS
IW/CPE ratio of 0.6 is optimum
Water management

21. The first 35 -40 days are the critical period of weed competition
Initial weeding by intercultural operation by 5 -10 days after first irrigation
Hand hoeing is desirable to aerate the soil
It also conserve the moisture
Herbicidesalso can be used
PE Pendimethlin @ 0.5 1.0 kg/habased on soil moisture
Fluchloralin @ 1.25 kg as preplant incorporation
POE isoporturan 0.75 kg/ha at 2-3 leaf stage
Nitrofen @ 1.5 –2.0 kg/ha can also done.
Weed management

22. Colour of leaves stem & silique turns to pale yellow
Lower silique looks dried appearance
 [
Seeds in the silique make rattling sound
Silique with 2 carpels and a false septum
During over maturity the two carpels split and seeds shed
 [
Premature harvest leads to shriveled grains
Harvesting & Threshing

23. Threshing
After sun drying
Beating pods along with the plants either manually or mechanically
Walking bullock or tractorcan also be engaged
Winnow the seeds, clean & drying to 8 to 10% moisture for storage
Averaging Yield
Irrigated rape seed 1.5 to 2.0 t/ha
Rainfedrape seed 1.0 to 1.5 t/ha
Irrigated Mustard 2.0 to 2.5 t/ha
RainfedMustard 1.5 to 2.0 t/ha

24. Sequential cropping
Fallow/millets/pulses –Mustard
Rice –Rape seed
Maize –Mustard
Intercropping
Mustard + chickpea
Sugarcane + Mustard
Barley/wheat/chickpea + Mustard
Potato + Mustard
