“…However, no significant difference in days to 50% flowering was noticed between 100% RDF and 125% RDF. Similar findings were reported by Triveni et al (2018). 125% RDF recorded an increase of 10.1% in plant height, 34.5% in productive tillers per plant, 18.4% in fingers per ear, 9.1% in earhead length respectively over 75% RDF; however it was on par with 100% RDF.…”

A field experiment was conducted at Agricultural Research Station, Vizianagaram during kharif, 2017 to know the fertilizer responsiveness of improved short duration finger millet genotypes. Experiment was conducted in split plot design with NPK fertilizer levels were assigned to main plots and improved finger millet genotypes were assigned to subplots. Results revealed that among the NPK fertilizer levels, performance of growth as well as yield attributes of finger millet at 100% RDF was on par with 125% RDF, however it was significantly superior over 75% RDF. Similarly yield and economics in 100%RDF was onpar with 125% RDF. Among the finger millet genotypes, highest growth, yield attributes, yield and economics were recorded in VL 386 when compared to other genotypes.

“…Among different NPK fertilizer doses, highest grain yield was recorded in 125% RDF which was 233.9%, 31.1%, 13.2% higher than absolute control, 75% RDF and 100% RDF respectively (Table 1). These results are in conformity with the results reported by Triveni et al (2018). In a long term fertilizer trial at Bengaluru, it was proved 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 (Sankar et al,2011) [5] .…”

A field experiment was conducted at Agricultural Research Station, Vizianagaram, Andhra Pradesh during kharif, 2019 to evaluate the fertilizer use efficiency of improved finger millet cultivars. Experiment was conducted in split-plot design with NPK fertilizer doses as main plot treatments and finger millet cultivars as sub plot treatments. Experimental results indicated that 125% recommended dose of fertilizer significantly increased plant height, productive tillers, earhead length, number of fingers per earhead, grain yield and straw yield apart from recording higher net returns and B:C. Among four improved cultivars, VR 1101 and WN 559 have outperformed in terms of yield and economics than other cultivars and national check varieties.

“…These improved varieties of finger millet responded well to the applied fertilizers/manures and resulted in better yields. Similarly, earlier studies also reported differential response in terms of growth and yield attributes of finger millet varieties to different fertilizer doses ( 25 , 26 ). It is evident that the yield differences between varieties was mainly due to their genetic potential and also due to higher tillers, ears m −2 and fingers ear head −1 .…”

Finger millet (Eluesine coracana L.) is gaining importance as a food crop with the increasing emphasis on nutritional aspects and drought resilience. However, the average productivity of the crop has stagnated at around 2,000 kg ha−1 in India. Recently released nutrient responsive high yielding varieties are reported to respond better to application of fertilizers/manures. Further, substitution of chemical fertilizers with organic manures to maintain sustainable yields and improve soil health is gaining attention in recent years. Therefore, identifying the appropriate rate and source of nutrition is important to enhance the productivity of finger millet while improving the soil health. A field experiment was conducted during two rainy seasons (July–November, 2018 and 2019) to study the response of finger millet varieties to chemical fertilizers and farmyard manure (FYM) on growth, yields, N use efficiency, N uptake and on soil properties. Two varieties MR-1 and MR-6 were tested with four nutrient management practices viz., unamended control, 100% recommended dose of fertilizers (RDF; 40–20-20 kg NPK ha−1), 50% RDF + 50% recommended dose of nitrogen (RDN) as FYM and 100% RDN as FYM. Among the varieties, MR-6 outperformed MR-1 in terms of growth, yield, N use efficiency and N uptake. The yield enhancement was up to 22.6% in MR-6 compared to MR-1 across the nutrient management practices. Substituting FYM completely or half of the fertilizer dose increased the growth and yield of finger millet compared to application of chemical fertilizers alone. Similarly, the average biomass yield, ears m−2, grain yield, total N uptake and N use efficiency in response to nutrient management practices followed the order of 100% RDN as FYM > 50% RDF + 50% RDN as FYM > 100% RDF. The soil organic carbon, available N, P, K, and S improved by 25.0, 12.9, 5.7, 6.1, and 22.6%, respectively in the plots under higher rate of FYM application (8 Mg ha−1) compared to plots under chemical fertilizers alone. We conclude that substituting chemical fertilizers either completely or by up to 50% with organic manures supplies adequate amounts of nutrients, improves the yield of finger millet, economic returns, and soil properties.
