Economically Important Part

Leaves are the most economically important part of Amaranthus

Conditions for Cultivation

Amaranthus is widely distributed in both tropical and sub tropical regions.

It is cultivated throughout the year in tropics and in autumn, spring and summer seasons in temperate regions.

Amaranth comes up well in well drained loamy soil rich in organic matter.

The ideal is pH is 5.5-7.5 but there are types which can come up in soils with pH as high as 10.0.

The soil should be brought to a fine tilth by ploughing 3-4 times followed by planking.

Major Challenges

Biotic Causes:
- Major Pests: Weevil, Caterpillar and Webber
- Major Diseases: Anthracnose, Damping Off, Wet Rot and Leaf Spot.
Abiotic Causes:
- Bolting

Crop Schedule

Crop Stage	Products	Dosage	Method Of Application	Benefits
2-3 weeks after sowing	Geoxol (Liq.)	10 ml per liter of water	Soil Drenching	Improves soil properties and promotes root development
3-4 weeks after sowing	PeakMAX	2 ml per liter of water	Foliar Application	Reduces disease pressure Rejuvenates plant growth quickly
3-4 weeks after sowing	Nutrin Combo	1 ml per liter of water	Foliar Application	Optimizing nutritional status
2 weeks before harvesting	Silixol OSA WP	2 g / ml per liter of water	Foliar Application	Improves quality of leaves , reduces incidence of abiotic stress
Deficiency of Iron	Nutrin Fe 12%	650 g / hectare / application, if soil Fe (less than 4.5 ppm),repeat application is recommended based on deficiency. Suitable for foliar sprays for crops grown on all types of soil.	Foliar spray	Corrects Iron deficiency
Deficiency of Iron	Nutrin Fe EDDHA 6%	2.5-5.0 kg / hectare / application, if soil Fe (less than 4.5 ppm),repeat application is recommended based on deficiency. Suitable for calcerous soils with pH above 7.5	Soil application	Corrects Iron deficiency
Deficiency of Boron	Nutrin Boron 20%	650 g / hectare / application, if soil Fe (less than 25 ppm),repeat application is recommended based on deficiency	Foliar spray	Corrects Boron deficiency
After 15-20 days of crop establishment	Mycoxol 4G	500 g/hectare/application, if soil pH (less than or equal to 7.5) and availble P (more than 15 kg/ha) - if fertigation is available	Soil application	Reduces incidence of soil borne diseases, improves availability of phosphorous and other micronutrients
After 15-20 days of crop establishment	Mycoxol Granules	10-20 Kg/ha/application, depending upon soil properties - if crop is on flood irrigation	Soil application	Reduces incidence of soil borne diseases, improves availability of phosphorous and other micronutrients
