Alasi ladoos are a local savory among indigenous communities in the undivided Koraput district, Odisha. Children prefer these Alasi ladoos and are consumed during their breakfast. These are sold in the local shandies (haats). Niger oil also has diverse industrial use.
Niger (Guizotia abyssinica) also known as Alasi in Odia and Ramtil in Hindi, is an erect, stout, branched annual herb grown for its edible oil and seeds. It belongs to the same family as Sunflower – Asteraceae. Niger or Alasi as it is locally called in Koraput is an oilseed crop. Niger crops, more poetically called “Alasi” in Odia, literally means ‘Lazy She”. Winter brings miles and miles of golden yellow fields, Stretching horizon to horizon, like a golden carpet. It is edible and is one of the important commercial crops for the local tribal communities. The local indigenous communities get cash by selling the Alasi seeds in the haats. They use this precious cash component to buy their other household-level food items and salt, in the rather barter economy in the region.
Alasi is mainly cultivated in during the monsoon season on hill slopes. It is a winter crop that grows abundantly in all parts of India up to the Himalayas at a height of 6000 feet above sea level. The crop differs in color, shape, and size as per the area it is cultivated. Accordingly, Alasi can be found in red, white, yellow, and black varieties. The yellow Alasi flowers during winter months along the hill slopes of Koraput is a treat for the eyes. It can be grown on degraded soils and requires little water and care. Generally, niger seeds are broadcasted by local indigenous communities. However, line sowing gives a better yield. The average yield of Niger is 350 kg/hectare.
The plant is an average of 1.4m but can vary significantly as a result of environmental influences and heights of up to 2m. It grows on almost any soil as long as it is not coarse-textured or extremely heavy. It is usually sown in areas with rather poor soil or on heavy clay soil under poor cultural conditions. Niger tolerates waterlogged soils since it grows equally well on either drained soils or waterlogged clays. Niger is extremely resistant to poor oxygen supply in soil because of its ability to develop aerenchymas under these conditions.
Niger seed and its crude oil is widely used in traditional nutritional and medicinal applications. It is high in micronutrients like calcium, phosphorous, sodium, potassium, fibers and has antioxidant properties. They add important nutritional values to diets as they are, high-quality proteins as well as oil-soluble vitamins like vitamin A. The seed contains 37- 47% oil, which is pale yellow with a nutty taste and a pleasant odour. The oil is used for culinary purposes, anointing the body, manufacturing paints and soft soaps, and lighting and lubrication. The niger oil is a good absorbent of the fragrance of flowers it is used as a base oil by the perfume industry.
Inadequate intake of micronutrients is a major public health problem, especially in populations of developing countries in which pregnant women and children are affected. Since infants need the proper amount and type of micronutrients for their healthy body growth, they need special attention in supplementing with micronutrients. Oilseeds like Niger can be used as sources of micronutrients. It can combat malnourishment caused by micronutrient deficiency.

Diseases and Pests
Niger is not affected by pests and diseases and can be grown with minimal care. However, niger blight (Alternaria sp.) and leaf spot are the most serious diseases. The other diseases include Alternaria leaf spot and Cercospora leaf spot, powdery mildew, and root rot disease. The pest populations include white flies and hairy caterpillars.

The way forward
- Niger can be promoted in most rainfed agricultural cropping systems by adopting natural farming practices.

- Conservation of these valuable resources in its natural habitat would be an appropriate approach for ensuring food and nutrition security for future generations.
- Conventional plant breeders and biotechnologists should undertake scientific validation of Niger crops to make their value explicitly known. This knowledge could be utilized for crop improvement and bio-prospecting.
- There is also scope for equitable sharing of benefits if used by the seed and pharmaceutical industries in the future.
