Current Til Rate 

Til Rate Today in Pakistan range from 10,500 to 13500 PKR for a 40kg bag and the price of sesame per kg ranges between 260 to 340 PKR.

Selecting the Right Varieties and Season for Til Crop Cultivation

Maximizing the yield and quality of til crop cultivation hinges on selection of varieties and sowing times, which should be selected carefully. Cultivation of til is determined by a number of factors including variety selection and planting schedule.

Popular Til Varieties for Commercial Cultivation

In addition to improving yield and disease resistance, several VRI varieties have been developed for commercial cultivation. These cultivars are adaptation-specific. The VRI varieties perform best when summer planted between mid-February to early March under irrigation. 

• Til varieties that achieve an early harvest are optimal for regions with a shorter growing season span. 
• Farmers are advised to plant varieties that are known to be resistant to prevalent diseases and pests in their locality.

Recommended Seasons for Planting in Various Regions

Sesame is best grown in the temperature range of 25°C and 30°C. Til is grown at an elevation of up to 1250 meters but has a narrow range of temperature within which optimal growth is attained. In many places, sesame is grown as a kharif (monsoon) crop in the arid and semi-arid tropics, while in cooler regions, it is grown as a rabi crop if sufficient irrigation is provided.

• In the semi-arid tropics, til is predominantly cultivated as a kharif crop. 
• Along with sufficient irrigation, cooler areas can support til during the rabi cultivation period.

Soil and its Preparation in Land Management

In the context of til cultivation, land preparation is one of the first and most important steps as it has a bearing on soil condition as well as crop yield. This type of farming requires deep, well drained and fertile land with appropriate soil reaction.

Til Cultivation: Ideal Soil Conditions

Til performs best when embedded in sandy loam or loamy soil with a ph between 6.0 to 7.0. The soil must also be well aerated and possess good retention of water.

Techniques: Step-by-Step Land Preparation

To prepare the land for til cultivation, follow these sequential steps:

• Start by plowing the whole field with a tractor two times, a moldboard plow three times, or a country plow five times to break up clods into fine tilth.
• Soils with hardpan formation need chiseling at 0.5m intervals perpendicular to the primary tillage direction roughly every 3 years.
• During soil preparation, such composting activities like 12.5 tons of farmyard manure or composted coir pith per hectare enhances soil fertility and its structure markedly.
• For irrigated til cultivation, form level raised beds of 10m² or 20m² and ensure precision leveling.
• In rice fallow systems, fields should be plowed lightly once with optimum soil moisture, seeded immediately and covered with a thin layer of soil from light plowing.

Applying the above land preparation p techniques enables farmers to foster optimal conditions for til coherence, enhancing vigorous development and increasing yields.

Selection, Treatment, and Sowing of Seeds

To achieve an optimal yield of til, focus should be placed on treatment, sowing methods, and especially seed quality. Adopting a positive approach towards these factors will greatly determine the productivity of til crops.

Seed Quality and Rate

Purchasing good quality seeds constitutes the first step towards effective til cultivation. The seed rate must correspond to variety, as well as the type of soil. Certified seeds lead to enhanced germination rates and uniformity in the crop.

Seed Treatment Methods

Seed treatment is important for safeguarding the seeds from various pests and diseases. With proper fungicide or insecticide treatments, seed and seedling vigor can be enhanced. This process aids in robust crop stand establishment.

Proper Sowing Techniques and Their Specific Spacing 

Sowing seeds in lines is preferred over broadcasting sowing as it improves crop management. Even distribution is achieved by mixing dry sand with seeds at a ratio of 1:4 and then distributed along furrows.

As the best results are obtained when rows are spaced 25-35 cm apart with an inter-row distance of 10-20 cm, then carefully placing seeds at 3 cm depth, this method minimizes resource use while optimizing healthy growth. 

Water Management and Irrigation Practices 

Til crops water management directly affects the success of the cultivation. Traditionally til is grown under rainfed conditions, though supplemental irrigation could improve yields significantly whenever water resources are available. 

Irrigation Schedule for Different Growth Stages 

For every growth stage within a til crop, irrigation schedule will differ. During critical stages such as 4-5 leaf stage, branching, flowering, and pod formation, irrigation should be performed at field capacity every 15-20 days after thinning. Surface irrigation during these periods should be maintained at 3cm depth, which provides a 35-52% increase in yield. During the vegetative phase (which is usually the 4-5 leaf stage or branching), as well as in the reproductive phase (flowering or pod formation phase), applying 2 irrigations of 3cm each will enhance both water efficiency and yield.

Water Management In Rainfed Compared to Irrigated Conditions

In the case of rainfed agriculture, efforts for moisture retention like mulching, maintaining the right population of crops, and contour farming become crucial. On the other hand, irrigated systems have to deal with scheduling issues which should avoid water logging and allow for enough drainage. If only one irrigation is feasible, it should be during the reproductive stage when the crop is the most sensitive to water stress.

Nutrient Management Along With Fertilizer Application

Paddy til farming requires optimally adjusting fertilizer application as well as managing nutrients differently to achieve high yields. Effective nutrient management requires understanding the essential nutrients needed for til crops and applying the appropriate fertilizers at the right times. 

Essential Nutrients For Til Growth

Like all crops til require proper nutrition for enhanced crop growth. In macronutrients nitrogen, phosphorus and potassium are found. Nitrogen is important for the leaves, phosphorus enables the roots, and potassium helps the entire plant.

Fertilizer Recommendations and Application Methods

The application of fertilizers should be based on soil test results to determine the nutrient deficiencies. For til cultivation, a balanced fertilizer dose is recommended. The fertilizer application methods include broadcasting, band placement, and foliar application.

Organic Manure and Biofertilizer Options

The use of organic manure and biofertilizers is a sustainable approach to nutrient management in til cultivation. Applying 5-6 tons of well-rotted farmyard manure or compost per hectare during land preparation improves soil structure and fertility. Biofertilizers like Azospirillum and Phosphobacteria can substitute up to 25% of the nitrogen requirement. The TNAU MN mixture is applied at 7.5 kg/ha for rainfed sesame and 12.5 kg/ha for irrigated sesame as enriched FYM.

Pest and Disease Management in Til Crops

Pests and diseases pose a significant threat to til cultivation, necessitating effective management strategies. Til crops are vulnerable to a range of pests and diseases that can drastically reduce yield if not properly managed.

Common Pests Affecting Til Cultivation

Til crops are affected by various pests, including insects that feed on the plants, reducing their growth and productivity. Regular monitoring is essential to identify these pests early and implement control measures.

Major Diseases and Their Control Measures

Til crops are susceptible to diseases such as Phyllody or leaf-curl and leaf-spot. To control leaf-spot, three sprays of Agrimycin at a rate of 100 PPM at two-week intervals are recommended. For Phyllody or leaf-curl, spraying Dimethoate 0.05% or Phosphomidan is effective. Removing and destroying affected plants can also help control the spread of these diseases.

Integrated Pest Management Strategies

Effective management of pests and diseases in til crops involves a combination of strategies. These include:

• Crop rotation and timely planting to reduce pest pressure
• Use of resistant or tolerant varieties when available
• Cultural practices like field sanitation and removal of crop residues
• Biological control agents such as predatory insects and microbial formulations
• Judicious use of chemical controls based on economic thresholds

By adopting these integrated management strategies, farmers can minimize the impact of pests and diseases on til crops, ensuring better yields and productivity.

Harvesting and Post-Harvest Handling

Effective harvesting and post-harvest handling are crucial for maximizing til crop yields and maintaining seed quality. Timely harvesting ensures that the seeds are collected at the optimal stage of maturity, which is vital for both quality and quantity.

Identifying the Right Time for Harvest

The right time to harvest til crops is when the leaves turn yellow and the capsules start to dry. This usually occurs around 90 to 100 days after sowing, depending on the variety and growing conditions. Monitoring the crop regularly is essential to determine the exact timing.

Harvesting Techniques to Minimize Seed Loss

To minimize seed loss during harvesting, it is recommended to cut the crop close to the ground and dry it further in the sun. Seeds should be collected after thorough drying to prevent moisture-related issues.

Post-Harvest Processing and Storage

After harvesting, the seeds should be winnowed to remove chaff and debris. Proper drying is critical; spread seeds in thin layers in the sun for approximately 3 days, stirring every 3 hours. Store the dried seeds in clean, dry gunny bags or airtight containers to maintain quality.

• Dry seeds to a moisture content of 6-8% for safe storage.
• Store seeds in a cool, dry place away from direct sunlight.
• For seeds intended for planting, consider additional care, including treatment with protectants.

Conclusion

To maximize yield and quality in til cultivation, farmers must adopt a holistic approach. This involves careful variety selection, meticulous land preparation, and judicious water management. By adopting recommended agronomic practices, farmers can significantly improve oil content and overall sesame seeds quality.

• Achieving successful til crop cultivation requires attention to detail at every stage.
• The economic potential of sesame continues to grow with increasing global demand for nutritious seeds.
