6. CLIMATE:-

Sesame is essentially a tropical crop grown in arid and semi-arid areas.
Lis generally cultivated in tropical and sub-tropical countries.

t's main distribution is between 250 s and 250 N Latitudes

ts altitude range is normally below 1250 m although some varieties locally adopted up to 1500 m.

Generally, it requires fairly hot conditions during growth for optimum yield.

rwrwrvwveyY

deal optimum temperature for growth is 25-270 C, Extremely low temperatures of 100 €, there is a
complete ceasing of growth,

Temperatures >40 C seriously affect the pollination when there is less number of capsules.

Sesame is a short day plant,

The crop can be grown entirely on stored soil moisture,

7. VARIETIES:-

> Popular varieties in Andhra Pradesh -Gauri, Madhavi, YLM-11, YLM-17, .
> Latest Variety in Andhra Pradesh -Chandana (ICS-94)

» Brown seeded varieties -Grown in Coastal areas.

> Gauri, Madhavi, YLM-11, YLM-17, Varada, Usha, TMV-6 ete.

> White seeded varieties -Grown in Telangana area

> Rajeswari, Swetha, Pratap, RT-125, Mrug-1, TG-22, T-12, T-78 etc.,

> Black seeded varieties -Krishna, Soma, etc.,

> Reddish brown variety -Rama.

8. SOILS:-

> Sesame comes up well on soils with slightly acidic (or)
neutral reaction. It can be grown on well drained soils and
performs well in light loamy soils.

> Itis highly sensitive to water logging.

> Very sandy, saline and alkaline soils are not suitable,

10. SEEDS AND SEEDING:-

SEED RATE:-

Rainfed Irrigated
Under broadcasting (Kg/Ha) 6 5
Row seeding (Kg/Ha) 5 4
Mixed (or) Intereropping-| Kg/Ha

SPACING:-
30 X 10 Cm in Telangana (all seasons)

45 X 15 Cm is also recommended.

12. SEED TREATMENT:-

> Seed treatment against seed and soil born diseases is essential for stand
establishment by preventing damage to seeds and seedlings emerging from soil.

> Seed can be treated with cow urine, Jeevamrutham, Panchagavvya, Biofertilizers
and Amruthapani,

13. » SEASON - TIME OF SOWING:-

> Season Time

> Telangana Kharif Second fortnight of July
> Rabi Middle of January

> METHODS OF SOWING:-

> |. Broad casting is usually most widely used in all situations. Seed is mixed with
sand in equal quantities (or) 3 times to facilitate uniform distribution of yield.

» After sowing, seed is covered by shallow ploughing and planting by cultivators
and harrowers

> 2. Line sowing (or) Row seeding is done with seed drills to promote higher yields.

> Optimum depth of sowing is 2-3 cm,

14. MANURES and FERTILIZERS:-

+ N-P-K REQUIREMENT:-

> Rainfed Irrigated

PON 40 60 '4 basal

»P 60 60% (30-35 DAS)
»K 40 40

> Fertilizer in organic farming depends on the following factors:

> On nutrients such as those in the soil.

> On the nutrients from the rain.

> On top of the soil fertilizer,

» Above ground microorganisms (nitrogen fixing bacteria, phosphorus, solubilizer bacteria, potash solubilizer).
> Depends on the nutrients sprayed on the crops.

> 10 tonnes of cattle manure per acre in the last Tillage,

» Spray the liquid Jecvamrutham once every 15 de

16. INTERCULTIVATION:-

> Sesame is sensitive to weed competition during the first 15-25 DAS. A
minimum of two weeding, one after 15 DAS and another 35 DAS are
required to keep the field relatively weed free. Row seeded crop facilitates
use of blade harrows for intercultivations. Two intercultivations, 15 DAS
and 35 DAS followed by one hand weeding keeps the field free of weeds.

19. IRRIGATION:-

> Water requirement is 300-350mm. For rabi crop 5-6 irrigations are required,

> [st irrigation -at sowing

> 2nd irrigation -3 WAS

> 3rd irrigation -6 WAS

> 4th irrigation -8 WAS

> Sth irrigation -9 WAS

> CRITICAL STAGES FOR IRRIGATION:-

> For rabi/ summer sesame, a pre sowing irrigation is necessary for optimum seed germination

and adequate stand establishment, Flower initiation and capsule filling stages are most
sensitive to water deficits,

21. SCHEDULING IRRIGATION:-

> Scheduling irrigations at 50% DASM is adequate. If irrigations are
scheduled based on IW/CPE ratio, a ratio of 0.6 is optimum under most
situations. Depending on soil type, weather conditions and crop duration,
irrigations may be given once in 12 to 15 days. If irrigation water is not a
limiting factor, flower initiation, maximum flowering and capsule filling
results in optimum seed yield. Depending on the duration, sesame water
requirement ranges between 350 and 450mm. The crop is usually irrigated
by check basin method of irrigation.

25. HARVESTING:-

> Depending on the variety, sesame crop takes 80-150 days for
maturity. The crop is harvested when the leaves, stems and capsules
begin to turn yellow and the lower leaves start shedding. To prevent
shedding of seed, the crop should not become dead ripe in the field.
The ripe plants are cut at the ground level carried to threshing yard,
stacked for a week in the sun with the cut ends upwards.

27. QUALITY CHARACTERS:-

> Sesame is the oldest oil seed crop of the world. The
seed has high food value because of the

> higher contents of good quality edible oil and
nutritious protein

28. SEED COMPOSITION:-

> Sesame seed protein content varies from 20-28% with an oil content ranging
between 48-55%, Its mineral content is around 6%..

> Among oilseed proteins, sesame seed proteins are more nutritious It is rich in
methionine and tryptophane. Like other oil seeds, it is also deficient in lysine.
The other limiting amino acids are thionine, isoleucin and valine. Sesame seed
contains 21-25% carbohydrates, 1% calcium and 0.7% Phosphorous.

> Sesame oil has two constituents namely sesamin and sesamol. They are
responsible for very high stability of oil at room temperature, and frying
temperatures. The sesamin content ranges from 0.07 to 0.6%.
