Abstract
A field study was conducted on the “Effect of NPK Levels and Micronutrients with and without Liquid Bio-fertilizer on Soil Health and Yield Attributes of Maize (Zea Mays L.)” Cv. K-25” at the Soil Science & Agricultural Chemistry Research Farm, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Kharif season 2018 and 2019. The soil of experimental area falls in order Inceptisol and soil texture was sandy loam. The result showed that in treatment T19[140:80:50 NPK kg ha-1 + Zn (20 kg ha-1) and Mn (25 kg ha-1) + Azotobacter (200 ml ha-1)+ PSB (200 ml ha-1)] nitrogen uptake in maize grain & stem (34.86 & 68.44 kg ha-1during 2018, 52.89 & 63.65 kg ha-1during 2019), phosphorus uptake in maize grain & stem (25.16 & 11.87 kg ha-1during 2018, 24.11 & 20.51 kg ha-1during 2019), potassium uptake in maize grain & stem (20.16 & 89.22 kg ha-1during 2018, 19.73 & 86.27 kg ha-1during 2019), zinc uptake in maize grain & stem(5.10 & 5.98 kg ha-1during 2018, 5.24 & 5.96 kg ha-1during 2019), manganese uptake in maize grain & stem(7.58 & 7.24 kg ha-1during 2018, 6.78 & 6.85 kg ha-1during 2019) as compared to T0 (absolute control).
