“…Based on a two year field trial, Bhoite and Nimbalkar [54] reported that application of 60 kg N ha −1 and 20 kg P2O5 produced the best finger millet yield in Maharashtra, India. Based on a 25 year long term experiment conducted under rainfed conditions on alfisols in Bangalore (Southern India), it was observed that application of N:P2O5:K2O at 50:50:25 kg ha −1 increased finger millet yield and soil fertility status compared tonon-fertilized plants [29]. The authors further observed that application of FYM and maize residues along with NPK enhanced the yield and soil fertility status.…”

“…The authors also claimed that the benefit/cost ratio was higher with the above treatment than the traditional farmer practices and in par with the recommended NPK at 100%. Sankar et al [29] also found that application of FYM at 10 t ha −1 + 50% recommended NPK fertilizer produced a much higher yield than the recommended NPK application at 100% (Table 2). …”

“…Hegde and Gowda [22] reported that the required application rate of NPK fertilizer depends on whether the conditions are wet or dry, with a higher rate of fertilizer required under irrigated conditions (100, 50, 50 kg N, P2O5, K2O) compared to dryland conditions (50, 37.5, 25 kg N, P2O5, K2O) in order to achieve their respective yield potentials (i.e., there is more biomass produced under wet conditions). Similarly Sankar et al [29] found that the benefit of applying inorganic fertilizer increased under high moisture availability compared to low moisture availability (<500 mm).…”

“…Some of these studies have been noted above. Generally application of FYM along with recommended NPK fertilizer enhances finger millet yield and soil fertility [25,29,30,34,37,42,58]. Kumara et al [37] found that application of FYM along with the recommended NPK fertilizer increased yield parameters of finger millet under an irrigated system in Bangalore, India (ear length, 1000 grain weight, number of fingers per ear head, ear weight per plant, and grain weight per plant).…”

“…The authors also found that poultry manure was a better source of manure than FYM or green manure for finger millet to achieve better growth and yield. Based on a very long-term comprehensive study , Sankar et al [29] found that application of FYM and maize residues increased millet yield as well as sustainability in rainfed semiarid tropical alfisols (Table 2). Furthermore, based on a long-term field experiment, Pushpa et al [36] found that application of FYM along with 100% NPK + lime increased root growth and root nutrient content (major, secondary and micro nutrients) compared to plants treated with 100% NPK alone ( Table 2).…”

Finger millet (Eleusine coracana (L.) Gaertn) is a staple food crop grown by subsistence farmers in the semi-arid tropics of South Asia and Africa. It remains highly valued by traditional farmers as it is nutritious, drought tolerant, short duration, and requires low inputs. Its continued propagation may help vulnerable farmers mitigate climate change. Unfortunately, the land area cultivated with this crop has decreased, displaced by maize and rice. Reversing this trend will involve achieving higher yields, including through improvements in crop nutrition. The objective of this paper is to comprehensively review the literature concerning yield responses of finger millet to inorganic fertilizers (macronutrients and micronutrients), farmyard manure (FYM), green manures, organic by-products, and biofertilizers. The review also describes the impact of these inputs on soils, as well as the impact of diverse cropping systems and finger millet varieties, on nutrient responses. The review critically evaluates the benefits and challenges associated with integrated nutrient management, appreciating that most finger millet farmers are economically poor and primarily use farmyard manure. We conclude by identifying research gaps related to nutrient management in finger millet, and provide recommendations to increase the yield and sustainability of this crop as a guide for subsistence farmers.

The understanding of the impact of nitrogen (N) fertilization on the field water cycle and corresponding water use efficiency (WUE) is very important for optimizing fertilization rates and conserving stressed water resources. We modeled soil moisture dynamics of maize (Zea mays L.), finger millet (Eleusine coracana Gaertn.), and lablab [Lablab purpureus (L..) Sweet] plots using calibrated HYDRUS‐1D model on two experimental sites (rain‐fed and irrigated) for three seasons under different N treatments. The results indicate that the effects of N depended on plant specific properties such as N‐fixation and drought tolerance, and on plant available water content governed by soil structure and rainfall seasonal variability. Maize WUE of plots which received 150 kg/ha of urea (46 N) were 10–30 kg/ha/mm higher than plots which received none; likewise, millet that received 50 kg/ha of urea had a 7–10 kg/ha/mm higher WUE than control plots in both experiments. However, differences in water cycle components were noticeable between N treatments only in the rain‐fed experiment, where higher N levels led to around 60 and 30 mm higher transpiration, 30 and 20 mm lower evaporation, and 30 and 15 mm lower percolation per season for maize and millet, respectively. In 2018, which was the driest year, the difference in maize WUE between the high and low N treatments was only 1 kg/ha/mm, which corresponded with low actual to potential transpiration ratios (). This indicates higher sensitivity of maize to water stress compared to the other crops. The results of lablab indicate a positive impact of N fertilization on WUE only under water‐limited conditions.
