SESAME CULTIVATION PRESENTED BYAASTHA SINHA ID NO. - 13001 ADVANTAGES OF GROWING SESAME CROP • One of the most water efficient crops. • Fit almost any cropping system. • Offers more potential return for less cost (less risk) than other crops. • Can be more profitable with limited resources than other crops using the same level of resources. • Excellent drought and heat tolerance, performs where other crops fail. • Common equipment used for other crops can be used to produce sesame. • Has shown excellent disease and insect tolerance and has shown to grow well in cotton root rot infested soils. ADVANATAGES CONTINUED… • Deep tap root may reach and utilize nutrients and moisture below the root zone of other crops. • As a non-host for root-knot nematodes, rotation with sesame has shown to reduce nematode levels. • Has worked well as a catch crop option when wheat or cotton crop failed. YIELD AND MARKETING OF SESAME •Yield of sesame is around 100-150kg/acre •TNAU has adviced farmers to immediately sell sesame after harvesting in may-june as price remains high during this period and farmers can easily sell it for Rs8085/kg. •Sesame oil price varies between Rs. 250-280/litre. •Total sesame production in india = 7.25 lakh tonnes. 0.15 lakh tonnes used as seed, 3 lakh tonnes for export and remaining for domestic consumption.

On capsule formation, larvae bore into capsule and feed on developing seeds. • 2- Aphids: - Crinkling and curling of leaves. Leaves appear shiny and sticky due to honeydew excreted by the insects. • 3. Gall fly : Asphondylia sesami • Maggots feed inside the floral bud • Leading to formation of gall like structure which do not develop in to flower/capsules. • The affected buds wither and drop. • 4. Linseed gall fly: • Fully grown larvae make a hole in the bud and damage the flower. •5. Hawk or Dead head moth (Sphinx caterpillar): •The young larvae roll together a few top leaves and feed them. •In the early stage of infestation, the plant dies without producing any branch or shoot. •In later stage of attack, infested shoots stop growing. •At flowering, larvae feed inside the flowers and on capsule formation, larvae bore into capsule and feed on developing seeds. Diseases of sesame • 1. Phyllody• All floral parts are transformed into green leafy structures followed by abundant vein clearing in different flower parts. • 2. Dry root rot• The fungus attacks young seedling, their stems become water soaked soft and incapable of supporting the seedling which falls over and dies. • 3. Phytophthora blight Disease can occur at all stages of the plant. SYMPTOMS•Initial symptom is water soaked spots on leaves and stems. •The spots are chestnut brown in the beginning later turn to black. •Premature leaf fall occurs. •Diseased plants produce shriveled seeds and gives blighted appearance. • 4. Alternaria blight DISEASE SYMPTOMS: The pathogen attacks all parts of the plant at all stages. •Small, dark brown water soaked, round to irregular lesions, with concentric rings appear on the leaves. •The lesions may also appear on the midrib and veins of the leaves. •Milder attacks cause only defoliation, in severe cases the plant may die. INTEGRATED PEST MANAGEMENT STRATEGIES 1.CULTURAL PRACTICES •Deep ploughing to reduce population of soil harbouring insect pests and nematodes. •Timely sowing and thinning operation should be done. •Keep the crop weed free for upto 45 days after sowing by hand weeding at 20 and 35 days after sowing. •Intercropping with green gram, red gram and pearlmillet is beneficial. •Grow resistant varieties as under: NAME OF VARIETY TOLERANT AGAINST TKG-21 Bacterial and cercospora leaf spot TKG-22 Phytophthora blight B- 67 Phyllody Krishna Alternaria leaf spot vinayak Leaf spots Gujarat til 2 Bacterial blight, wilt and phyllody Haryana til 1 phyllody 2. MECHANICAL PRACTICES •Collection and destruction of larvae of hawk moth, leaf roller/capsule borer and hairy caterpillar •Uproot phyllody affected plants. •Mechanically remove the roots of previously harvested crops as they harbour nematodes. 3. BIOLOGICAL CONTROL • seed treatment with Trichoderma viride (20g/5kg seeds) helps in controlling root rot. 4. Chemical control •INSECT PEST •To control defoliators, capsule borer and gall midge, spray 2 rounds of neem oil 2% at interval of 7 days. •Spray any of the following chemicals ( Dust formulation- 10kg/acre, liquid- 500ml/100L) chemical formulation Endosulfan 0.07% Carbaryl 0.15% Quinalphos 0.05% Dimethoate 0.03% Malathion 5% D Endosulfan 4% D CHEMICAL CONTROL OF DISEASES •Dryroot rot, alternaria leaf spot and phytophthora blight can be treated by mancozeb spray 0.25 – 0.5kg / acre in 300 l of water at 10 days interval. •Phyllody can be treated by 2-3 foliar spray of Dimethoate 30 EC (1 ml/lit of water). WEED CONTROL •Alachlor or Thiobencarb can be used as PRE spray for effective control of weeds •Use of PRE herbicides followed by one hand weeding around 30 DAS is the most appropriate way of weed management in sesame. DO’s and DONT’s in sesame IPM DO’s DONT’s •Grow resistant and tolerant varieties. •Adopt crop rotation. •Use organic manure, FYM, neem cake and bio-fertilizers. •Adopt synchronised sowing. •Discourage susceptible varieties. •Avoid monocropping. •Discourage excessive use of chemical fertilizers. •Avoid staggered sowing Basic precautions in pesticide usage •Always cover nose, eyes, mouth and use hand gloves, face masks and cap. •Avoid carrying bulk pesticides on shoulder/head/back. •Always read container before preparing solution and don’t use defective equipments. •Don’t apply on strong windy days or against the direction of wind. •Avoid entry of workers and animals in the field immediately after spraying. TYPES OF SESAME SEEDS • Brown Seeds- Known for their high content of oil around 45-50% and are used for extraction of oil. • White Seeds- known for their nutty flavor and it is mostly found sprinkled over buns and cakes. • Black Seeds- The black seeds are rich in flavor and are mostly used as a seasoning in salads and also for medicinal purposes. • Red Sesame Seeds-The red seeds are rich in aroma so they are mainly used in dishes to enhance the taste. VARIETIES AND CROP ROTATION • White seeded varieties- Rajeswari, Swetha, Pratap • Black seeded varieties- Krishna, Soma • Reddish brown variety - Rama. • High yielding varieties of UP are Pragati and shekhar • Rice / Potato – Sesame. • Cotton – Sesame – Wheat. • Sesame – Groundnut / Cotton / Maize • INTER CROPPING:Sesame + Greengram (1:1) Sesame + Pigeonpea (2:1) Sesame + Soybean (2:1) Requirements • SOIL It is highly sensitive to water logging. Very sandy and alkaline soils are not suitable. In case of alkaline soil add gypsum (5kg/300 square meter area) to reduce pH. • CLIMATE Generally, it requires fairly hot conditions during growth for optimum yield. Ideal optimum temperature for growth is 25-270 C and most suitable time is rainy season (JulySeptember). Sowing is done in june-july. Seed rate, spacing and treatment • SEED RATE: Under broadcasting – 5-6(Kg/Ha) Row seeding – 4-5(Kg/Ha) Mixed (or) Intercropping - 1 Kg/Ha • SPACING:30 X 10 Cm (all seasons) 45 X 15 Cm is also recommended. • SEED TREATMENT:Seed treatment with Thiram (3g/kg) is effective against seed borne diseases. Seed treatment with azospirillum (25g/5kg seeds)is also beneficial. Methods of sowing • 1. BROADCASTING Broad casting is usually most widely used in all situations. Seed is mixed with sand in equal quantities 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 – it is generally done with seed drills to promote higher yields. Optimum depth of sowing is 2-3 cm. Integrated Nutrient management • Integrated nutrient management consists of seed treatment with azospirillum (1 packet or 200g for 10kg seeds) • Application of 5 t/acre of FYM • 4 packets of Azospirillum (800 g/acre) and 4 packets (800 g/acre) of Phosphobacteria or 8 packets of Azophos(1600 g/acre)as soil application. • Spray 1% DAP (1KG in 100 litres of water) at the time of first flowering and again 10 days after first spray. • METHOD OF APPLICATION :Placement of fertilizer at seeding using seed drills is more effective than broadcast application. Irrigation schedule • Sesame is a drought tolerant plant and can grow in soil which has retained moisture from last rainfall. • 1st irrigation - at sowing • 2nd irrigation - 3 Weeks After Sowing • 3rd irrigation - 6 WAS • 4th irrigation - 8 WAS • 5th irrigation - 9 WAS • CRITICAL STAGES- Flower initiation and capsule filling stages are most sensitive to water deficits. 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. • 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. Processing of sesame •Manual processing and oil extraction can be done by ghani process(large sized mortar and pestle are used) or using small level expeller. Small processing equipments •Small level expellers are used. •manual oil extraction machines or screw press oil extraction machines are used. Mechanical processing of sesame • The Plant covers the complete process from Pre Cleaning, De hulling, Post Cleaning & Colour Sorting to give seeds that are; Clean & Color Sorted as per required purity. • The cleaned seeds are used for confectionary or production of value added products like Tahinia, Halwa, Turkish delight, etc. USES OF SESAME • Primary use of sesame is as a cooking oil. Sesame contains natural oil-soluble and water-soluble antioxidants. • Foods fried in sesame oil have longer shelf-life. • As with other vegetable oils, sesame oil has been used to make soap and margarine. • The oil is used in many intra-muscular injections as a carrier to spread the medicine faster. • Many insecticides use sesame oil as a synergist for the active agent. USES OF SESAME CONTINUED…. • Sesame paste is mixed with peanut butter to enhance the flavor and the extend the shelf-life. • In the Middle East sesame is made into a sweet known as halva, which is considered as a high energy food. Similarly, sesame is used in many sweets throughout Asia. • In the western world sesame is primarily used as a confectionary. The seed is dehulled and placed on top of buns and breads. • The seeds are incorporated into crackers, food products and items such as sesame sticks. • • • • • • • • Full of protein. Helps prevent diabetes. Reduces blood pressure. Lowers cholesterol. Prevents cancer. Helps in digestion. Good for the health of skin. Helps lessen anxiety. THANK YOU
