“…Different nutrient management treatments had similar but significantly higher harvest index compared to unamended control. Differences in harvest index of finger millet to varied supply of organic and chemical fertilizers was reported by Chowdary and Patra ( 40 ). Mineral nutrition has a major role in influencing the harvest index ( 41 ).…”

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.

Aims: To study the effect of zinc fertilization through soil and foliar at different stages of finger millet on yield, yield attributes and quality in two major finger millet varieties under rainfed alfisols of southern zone, Andhra Pradesh Study Design: Split-plot design Place and Duration of Study: Wetland farm, S.V Agricultural College, Tirupati and during kharif season of 2019 and 2020 (Two seasons) Methodology: Zinc fertilization to two major finger millet varieties viz., Vakula and Tirumala through soil and foliar application at different crop stages with following treatments viz., Control (No fertilizers and manures); RDF (60 -30-20 kg N-P-K + FYM @ 4 t ha-1); RDF + soil application of ZnSO4 @ 25 kg ha-1 as basal; RDF+Soil application of chelated-ZnSO4 @ 5 kg ha-1; RDF+foliar application of 0.2% ZnSO4 at ear head emergence stage; RDF+foliar application of 0.2% ZnSO4 at grain filling stage; and RDF+foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stage. The yield, yield attributes and quality parameters viz., protein, zinc and iron content in grains were determined by adopting standard protocols. Results: The application of zinc significantly (p<0.05) improved the yield and quality parameters over control. The foliar application of 0.2% ZnSO4 at ear head emergence and grain filling stage was significantly (p≤0.05) improved the yield and yield attributes of finger millet over RDF. The grain yield, straw yield, no. of productive tillers per plant, no. of fingers per plant were increased to 57.0%, 83.2%, 44.6% and 51.7%, respectively over RDF i.e., 60-30-20 kg N-P-K + FYM @ 4 t ha-1. The quality parameters namely protein, grain zinc and iron also increased up to 40.7%, 69.5% and 43.2%, respectively over RDF. Conclusion: Application of zinc sulphate at ear head emergence and grain filling stages enhanced the yield, yield parameters and quality parameters compared to other treatments of tirumala variety under rainfed alfisols of southern zone of Andhra Pradesh.
