The new variety of sesame has compactly packed capsules in the stem.
SESAME (GINGELLY) is a short duration oilseed crop of promise, and it can be ideally integrated into crop rotations with long duration crops.
It can be raised with residual soil moisture, and with a few irrigations it can establish itself well to yield rich dividends.
Being an early crop with high productivity, it is always preferred by the farmers. There are a number of improved varieties of sesame suited for different regions available for commercial cultivation.
Now, one more high yielding variety has been added to that. Named, Thillarani, the new variety was developed by the scientists at the Kerala Agricultural University (KAU), Thrissur.
It was evolved by combination breeding to combine the yield potential of Thilak and the duration of Kayamkulam-1, the two varieties released by KAU earlier.
Thillarani has a high yield potential and it can yield on an average about 580 kg seeds per hectare. Its seed oil content is 50.2 per cent.
The compact packing of capsules in the stem is the special feature of this promising variety. It comes to maturity in 77 days, according to the scientists.
The new variety is ideal for broadcast sowing, and a seed rate of 5 kg is required to cover a hectare.
The field should be thoroughly worked to bring it to a fine tilth. About 5 tonnes of ripe farmyard manure should be incorporated with final ploughing.
The recommended dose of nutrients is 30 kg each of nitrogen and potash, and 15 kg phosphorus per hectare. The entire dose of the nutrients should be applied as basal dressing. The field should be kept free of unwanted vegetation. Two to three manual weedings would be needed to eliminate the undesirable vegetation. Thinning should be done within 15 days of sowing to maintain a healthy population retaining a spacing of 15-20 cm between the plants. The variety responds well to sound crop and nutrient management practices.
Though, it is drought tolerant variety, a few irrigations at critical stages of crop development such as peak vegetative phase and at flowering stage would prove to be rewarding. The yield will improve considerably with good water management strategies.
The crop also responds well to foliar spraying with 3 per cent urea at 25 days of sowing, according to the scientists.
The crop may be harvested when the leaves turn yellow and when the compactly packed capsules in the stem are well formed and start turning brown.
The whole plants are harvested, and allowed to dry for a while before threshing. The seeds with high oil content will get a good price in the market.
