ABSTRACT
In India fnger 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 efciency. 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 diferent 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

recorded signifcantly 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–fnger millet rotation in alfsol of semi-arid region. Cropping system approach either sequential
or intercropping with legume was found benefcial. Treating seeds with Azospirillum brasilense (N fxing
bacterium) and Aspergillus awamori (P Solubilizing fungus) @ 25 g kg

seed of fnger millet found to be
benefcial. 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 diferent options of nutrients
application to fnger millet for sustainable productivity is reviewed.
Highlights
m The maximum yield potential of fnger millet can be achieved through proper nutrient application.
m Balanced fertilization and cropping system infuence fnger millet productivity.
m Integrated nutrient management and STCR based nutrient management are beter options of nutrient
management in fnger millet.

Millets exhibit unique characteristics amongst
cereals. These can grow well under dry and aberrant
weather conditions, can cope with relatively poor
soils and require comparatively less external inputs
than major cereals, namely rice, wheat and maize.
Millets are a staple food with superior nutritional
qualities and used both as food and fodder. In
addition, millets sequestrate carbon, thereby adding
to CO

abatement opportunities, contribute to
enhanced agro-biodiversity by their rich varietal
diversity, ecologically benefcial (Brahmachari et al.
2018), allow for mutually benefcial intercropping
with other important crops (Maitra et al. 2000).
Under the changing scenario of global warming and
climate change, cultivation of ecologically sound
and hardy millets may be a wise alternative for
optimum output with food and nutritional security.
India is the largest producer of various kinds of
millets. Out of the total minor millets produced,
fnger millet (Eleusine coracana L. Gaertn) accounts
for about 85% of production in India (Sakamma et al.
2018) and it has the pride of place in having highest
