Method of Planting
Hand Drill/ Wheat drill
Drill the seed in lines (45 cm apart) in good moisture (water) condition. Ensure that seed placement should be at depth of 2-2/12 cm.
Tractor mounted Drill
In case of Tractor mounted drill, prior to sowing, check the drill thoroughly and tractor speed should not exceed 8 km/hour to avoid the uneven sowing depth and seed placement.
Surface moisture influences the sowing depth and ultimately the seed germination. To achieve satisfactory germination, shallow depth of 2-2 1/2 cm is recommended. Deep sowing will result in poor emergence. As the temperature in Kharif season (June, July) is near 40 C, seed depth can be maintained at 3.5 cm (1 1/2 inch) to avoid drying effect and ultimately better plant emergence.
Soil fertility is the major manageable factor in sesame production. Nutrient balance is of vital importance. To achieve the best results, apply the fertilizers as mentioned below:
- Urea (1/2 bag) + DAP (1 bag)/ acre or,
- Urea (1/2 bag) + Nitrophos (1 bag) / acre
- Apply either combination prior to sowing
Usually 3-4 irrigation are required during whole season. Number of irrigation varies with the environmental conditions. In case of no rain, first irrigation should be given at 15-20 days after sowing (DAS). Second irrigation be also given after 30-40 DAS. Third irrigation at the time of flowering, because the irrigation at flowering, capsule formation and seed development is necessary to avoid moisture stress at these stages in order to ensure better yield formation.
Thinning and Hoeing
Plant emergence takes about 5-6 days after sowing. When the plants attain height of 10-15 cm, single out the weak and diseases plants by keeping 10 cm spacing between plants following 222000 plants/ha. First hoeing is done after 15-20 days and second after 30 days of germination with khurpa or Tarphali.
The following commercial sesame varieties should be planted. Pb.Til-90, – P-37-40, – Til-93,
– S-17, – PR-19-9, – Ts-3
In addition, there are various promising and improved pipeline varieties developed by Oilseed Res Programme at National Agricultural Research Center (NARC), Islamabad. These include:
Rattodero-1, Rattodero-2, Sanghar-1, Johi-1, VCR No.5, S-209.
The yield potential of these improved varieties is upto 1800 kg/ha.
