Ragi
Ragi (finger millet), a staple food grain for the rural population and is a rich source of calcium, iron, protein, and fiber. The cereal has low fat content and its carbohydrates have the unique property of slower digestibility and can be regarded as food for long sustenance. Most of the soils in the semi-arid tropics, where finger millet is grown, are deficit of major micronutrients, mainly due to continuous cropping, low use of mineral fertilizer and low rates of organic matter application which limits yield potential . Therefore, it is important to optimize nutrient management practices and other related factors affecting finger millet cultivation in order to attain better yields under the comparatively marginal local growing conditions Various bio-fertilizers and manures that can be used for extensive production are mentioned below :-
- Nitrogenous (N) bio-fertilizer
- Phosphatic (P) bio-fertilizer
- Potash (K) bio-fertilizer
