A field experiment was conducted during kharif seasons of 2007 to 2011 at AICRP for Dryland Agriculture, UAS, Bangalore to study the response of fingermillet to limiting nutrients and balanced nutrition in Alfisols. The pH of soil increased due to liming. Application of Ca, Mg and B along with major nutrients (recommended dose of N and K₂O + borax at 10 kg/ha, and recommended dose of N and K₂O + lime at 300 kg/ha + MgCO₃ at 150 kg/ha + borax at 10 kg/ha) showed improvement in soil fertility status. The latter treatment also recorded significantly higher grain yield of fingermillet (3,706 kg/ha), B:C ratio (2.78) and SYI (0.82) compared to application of recommended fertilizer. Higher uptake response, nutrient use efficiency and nutrient recovery was also observed in the same treatment.
