A field experiment was conducted during k harif 2017 on sandy loam soil of S. V. Agricultural College wetland farm, Tirupati campus of Acharya N.G. Ranga Agricultural University to study the effect of zinc fertilization in combination with organic and inorganic sources of nutrients in finger millet. Yield attributes and yield was significantly influenced by the application of zinc in combination with either inorganics or integration of both inorganics and organics.Application of 100 percent RDF through inorganics + Soil application of ZnSO4 @ 50 kg ha produced significantly higher yield attributes (number of earheads m-2, number of fingers earhead-1, earhead length, earhead weight, grain weight earhead and thousand grain weight) and yield (grain yield, straw yield and harvest index). However, it was comparable with application of 75 per cent RDF through inorganics + 25 per cent RDF through FYM + Soil application of ZnSO4 @ 50 kg ha were significantly superior over the rest of the treatments tried.
KEY WORDS: Finger millet, zinc application, inorganics, organics, yield
