Nutrient Management in Finger Millet (Eleusine coracana L. Gaertn) in India
In India finger millet is mostly cultivated in resource poor soils of tropics and sub-tropics. Synchronizing nutrient supply with crop demand is essential to maximize yield and fertilizer use efficiency. It has been found that incorporation of N fertilizer during seeding stage increased yield as compared to broadcasting of fertilizer. The continuous application of inorganic N fertilizer reduced the soil organic carbon level. The foliar application of 2% urea produced higher grain and straw yield. Application of fertilizer P @ 125% recommended dose of phosphorus (RDP) with recommended N, K and FYM in different fertility soils recorded higher grain and straw yield. Nutrient management for targeting production and sustainability, integrated nutrient management (INM) will be the most suitable option. Application of 100% NPK along with FYM @ 10 t ha-1 recorded significantly higher grain and straw yield and enriched the soil organic carbon. Application of farmyard manure (FYM) alone or in a combination with chemical fertilizers contributed to higher amounts of carbon inputs and build up a higher soil organic carbon pool in rain fed groundnut–finger millet rotation in alfisol of semi-arid region. Cropping system approach either sequential or intercropping with legume was found beneficial. Treating seeds with Azospirillum brasilense (N fixing bacterium) and Aspergillus awamori (P Solubilizing fungus) @ 25 g kg-1 seed of finger millet found to be beneficial. Soil test crop response (STCR) need to be considered for supplying nutrients more precisely with a target yield output. In the present paper, the available literature on different options of nutrients application to finger millet for sustainable productivity is reviewed.
