Niger also known as Ramtil is an erect, stout, branched annual herb grown for its edible oil and seeds. Plant is average of 1.4 m, but can vary significantly as a result of environmental influences and heights of up to 2 m. It is normally adapted to different environments: cool tropical Eastern Africa, hotter tropical and subtropical lowlands of India and temperate Europe. It grows on almost any soil as long as it is not coarse-textured or extremely heavy. It is usually sown in areas with a 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.
