Different makes use of
Tender shoots might be taken as salad. Meal or seedcake could be very nutritious feed for livestock.
Origins: (a) Ethiopia and Afghanistan; (b) India and Myanmar
Many cultivars differing in flower coloration, diploma of spininess, head measurement, oil content material, resistance to ailments.
Local weather and soil
Safflower is grown as summer time crop in areas of medium altitude as winter crop in low altitudes; is customized to dry land or irrigated cropping system.
Not appropriate in areas with rainfall above 1000 mm. Mild, effectively drained soils with a pH of about 7 is discovered to be greatest. Crop is inclined to elevated humidity or extended waterlogged circumstances, notably in the course of the flowering season.
Dry circumstances are favorable for flower improvement. Thrives effectively as a winter crop within the South (Tsirang) and as a summer time crop in Western Bhutan (Paro / Thimphu).
Sowing and Planting
Sowing time
Subject is ready by plowing a few times till high quality texture is achieved. Elevate beds at 1 m width holding the lengths as permitted by the sphere. Irrigate the sphere previous to sowing whether it is dry.
Sowing is carried out within the months of April-may and September -October within the areas of medium altitude and low altitude respectively. Sowing time must be adjusted to keep away from rainfall throughout blooming stage. Presoaking of seed for 24 hours is usually recommended to make sure good germination. Seed charge varies from 17-20 kg / ha.
Sowing Distances:
• Row to row: 20 cm = 5 furrows / mattress
• Plant to plant: 10 cm
• Depth: 2.5 cm
Manures and fertilizer: Apply Farm yard manure when vegetation begin to type buds to extend flower manufacturing. Add 10 tons of FYM.
Cultural practices
Safflower could be very delicate to weed competitors throughout its rosette stage; subsequently preserve vegetation weed free throughout this vital part (weeding a minimum of twice after germination and after 4-leaves stage). An essential operation clipping to induce flowering is carried out after two months of plant improvement.
Harvesting petals
Petal harvest begins 5 months from sowing. Petals are cleanly nipped with the assistance of scissors at their clump three days after bloom. We advocate to repeat petal harvest after 2 to three days.
Harvest most popular throughout morning hours to realize max. Substances and coloration. Unfold petals on a clear tarpaulin and dry underneath shade. Pack in air tight moisture free containers.
Highest yield of 120 kg / acre proven in third week of March as proven in graph.

It’s delicate to the provision of sunshine particularly within the first yr.
Caraway grows effectively on quite a lot of soils. Sandy loam soils wealthy in natural matter are most popular. The best yield might be obtained when cultivated in deep, humid (though with out floor water) medium soils. Dry sandy soils, areas the place water accumulates and arid soils should not appropriate for the cultivation of cara
Vegetation are raised both from seeds. Plow twice & take away weeds fastidiously. Apply enough manure (as much as 15 tons of FYM / acre) and put together a high quality floor for sowing. Seeds are sown immediately within the subject both by broadcasting or sown on traces 2-Three cm deep, 20-30 cm aside @ 1.Three kg / acre throughout months of March and April. After germination when the plantlets are about 5-6 cm tall and have 6-7 leaves, skinny out the seedlings to a spacing of 30-40 cm. Weed commonly and irrigate each two weeks in dry months. The vegetation over winter and re-emerge subsequent spring (second yr). When vegetation are about 10 cm tall (April) apply effectively matured compost or FYM as a facet dressing after a spherical of weeding.
Harvest & Put up-harvest Operations
Harvesting is finished by chopping under the bottom department or pulling up the plant. Keep away from abrupt shaking to forestall seed shattering. Harvest throughout early hours of the day. In subtropical areas the place the crop is planted in autumn, it’s prepared for harvesting in March -April, whereas in temperate areas the plant flowers solely after winter is over. It matures within the subsequent yr in July after 15 months. The crop is harvested when the oldest seed has turned brown.
