Soil and Climate Requirements for Growing Kalmegh

It can be grown on a wide range of moderately fertile soils, from loamy to lateritic soils. It can also be grown in dark wastelands. The plant needs warm, humid conditions with plenty of sun to thrive. With the onset of the monsoon, the plant develops abundantly and begins to bloom in September, when the temperature begins to normalize. The plant thrives in tropical and subtropical climates across India. It can withstand a few hours of partial shade from trees, although it is grown in open areas.












Nursery

  • At the beginning of September, the seeds are soaked in water for 24 hours before being sown in nurseries.

  • For one hectare of land, about 650-750 grams of seeds are needed.

  • The nursery is prepared with a 1:1:1 ratio of soil, sand and organic matter and sown in early September at 5 cm spacing in rows, germination taking 8-10 days.

  • Seedlings are planted in the field at a spacing of 30X15 cm or 15X15 cm when they are six weeks old.

  • The seeding rate for a direct planted crop is 1.5 kg/ha and it is dispersed in a thin layer. Although it matures quickly, it is best grown in a nursery.

  • FYM is mixed into the soil at the rate of 20 kilograms per square meter for nursery beds.

weeding

The field should be free of weeds as it is a herbaceous plant. During the growing season, two to three weedings are necessary, at 20 days and 60 days after transplanting.

Application of manure and fertilizer

Kalmegh should be grown without the use of chemical fertilizers or pesticides. For better quality yield, organic fertilizers such as farmyard manure (FYM) at 10 t/ha and vermicompost at 2 t/ha can be used.












Harvesting and processing

The crop matures after 120 days from sowing and is ready for harvest. When the majority of the plants flower, they are harvested. Plants should be uprooted at this stage. A small number of healthy plants, however, should be left in the field for seed production. When the fruits are fully ripe, they should be harvested and dried in the sun, and the seeds should be collected. The seeds must be completely dried in the sun. After that, they are kept in airtight containers until they are ready to sow again.












Yield

A well maintained crop grown during the monsoon season gives a yield (whole pants) of 2.5 tons per hectare. It has a large demand and brings a reasonable profit to growers.
