Sesame til sowing time, spacing and yield for kharif in Rajasthan.

Sesame (til) is a low input kharif oilseed that suits light, well drained soils. Sow with the onset of monsoon, usually late June to mid July, at a low seed rate of about 3 to 4 kg per hectare, often mixed with sand for even spread, keeping 30 to 45 cm rows and thinning plants to about 10 to 15 cm apart. Use improved varieties recommended for your zone. Yields are modest, commonly 3 to 6 quintal per hectare under rainfed conditions, but sesame fetches a high price. Watch for waterlogging, which sesame cannot tolerate, and for phyllody disease and leaf webber pest. Harvest when lower capsules turn yellow and stack to dry. Confirm recommended varieties with your KVK.
Mixing the tiny seed with dry sand or sieved soil before sowing gave me a much more even stand. Broadcasting it alone, the seed fell in clumps and I had to thin a lot. After germination I thin to keep one plant every 10 to 15 cm so each plant branches well.
Waterlogging is the real killer here. The low spot in my field where rain water stood for a day or two lost the whole sesame patch, while the well drained part did fine. Sow til on the lighter, higher draining part of your land and on ridges if heavy rain is likely.
Rogue out phyllody affected plants early; they show leafy green flower parts and never form proper capsules. They act as a source and the leafhopper that spreads it can carry it to healthy plants. Pulling them out as soon as I spot them kept the disease low on my crop.
